CYPECAD - User manual
1.3.2. Manual introduction
neral dead and live loads of the structure have already
been introduced when defining the floors and so need
not be introduced here. The self weight of the supporting elements (columns, walls, beams and panels) are
generated by the program and so do not have to be introduced.
If an empty job is chosen, the user must manually introduce all the properties of the job.
In order to simplify the introduction of these properties, it is
important to be methodical. We suggest the following steps
be taken to carry out the project within CY
PECAD, or alternatively, any other method can be followed as long as the
creation of the information is structured and coherent.
• Stair introduction. (Beam Definition tab, Job menu).
• Integrated 3D structures introduction. (Beam Definition tab, Job menu). Introduction of the 3D structures
defined in Metal 3D.
• General data. (Column Definition, Beam Definition
and Results tabs, Job menu). Upon creating a new
job, a name and description must be assigned to it, the
materials to be used and their respective options must
be indicated, as well as the type of control to be undertaken in its construction.
• Foundation introduction. (Beam Definition tab,
Foundation menu). Introduction of pad footings, strap
and tie beams. For mat foundations, these must be introduced from the Panels menu at foundation level.
• Column and shear wall introduction. (Column Definition tab, Introduction menu). Description of the column and shear wall geometry and their respective positions.
• Er
ror identification and correction. (Results tab,
Contour Maps and Deformed Shape). Having analysed the structure, the next step is to check the error
messages related to the structural elements. All those
requiring dimension modifications must be corrected
and then the job must be re-analysed so to verify no errors arise and for the changes in self weight of the
structure to be readjusted. This must be repeated until
those errors implying dimension modifications to be
carried out disappear. If no dimension modifications are
required, the results may be taken as valid.
• Analysis of the structure. (Beam Definition tab,
Analyse menu).
• Floor definition. (Column Definition tab, Introduction menu). Description of the levels of the structure,
group organisation, heights between floors and the live
and dead loads they must support.
• Wall introduction. (Beam Definition tab,
Beams/Walls menu. Introduction of the walls supporting the structure.
• Beam introduction. (Beam Definitio
n tab,
Beams/Walls menu. Introduction of the beams of the
floor.
• Preparation of the results. (Results tab). This is the
previous step to generating the drawings. Here, the
floor slab reinforcement can be edited or made more
uniform, column reinforcement can be modified and columns may be grouped, if the user wishes to do so. Text
positions can also be corrected here without the need
of having to wait to make the corrections in the drawings.
• Floor slab introduction. (Beam Definition tab, Panel
menu). Introduction of the floor slabs to be used in the
structure.
• Special load introduction. (Beam Definition tab,
Loads menu). This consists in introducing loads that
have not yet been taken into account, such as those
due to internal partition walls. Please recall that the ge-

1.3.3.4. Search
It is possible to import text files in columns or limited by
commas to generate the foundations based on files exported from data sheets or other programs.
Upon clicking on the Search button, the Search for job
using thesaurus dialogue box appears. This options allows the user to search for jobs in the directory selected in
the pr
evious dialogue box (File manager) which contain the
word indicated by the user in their name or description.
From the files, the different loadcases are imported, as are
the forces at the column starts for each simple loadcase
and the column base dimensions.
The import process is as follows:
Click on File > Import > Import ASCII file. A window
will emerge asking for the name of the job in which the
foundations are to be created.
Subsequently a new window will open from which the file to
be imported must be selected.
Having concluded the import, the job will have to be analysed.

1.3.3.5.3. Share
These options are found in the File manager window. All

Using this option, the user can share a job compressed
with .CYP format. The job will be published on a server and
will be accessible to third parties via a private link. Therefore, only those who know the correct link will have access
to the job.
The user can include a title and a comment on the job to be
shared. Another dialogue box will then appear which indicates the link where the job is located, which may be copied by selecting it using the left mouse button so it may be
provided to the person he/she wishes to see it. This dialogue box also opens the website where the job has been
published.

The file links.txt, which is generated in the directory
usr/cype/cypecad contains the links of all the jobs that have
been published.
1.3.3.5.1. Send
Using this option, the user can send the job to an email address selected from the scroll menu or save the compressed job to a directory of his/her choice (Only compress
job). The user can optionally select whether or not to incl
ude safety copies that may have been created from previous versions, or to include the associated files (the results from the last analysis).
Any CYPE program screen can be captured to then share
on internet via a private link which the user can then provide
to or publish wherever he/she wishes to. Only those who
know this link will have access to the captured image.

displaying the captured screen image and where the user
can assign it a name and add a comment. Within this dialogue box, the user has the option to select only part of the
captured image for it to be published. To do so, select the
area of the image by opening a selection window over the
image using the left mouse button.
Having accepted the dialogue box, the program offers the
user in a different window, two types of URL a
ddresses so
the user may insert the captures in any forum. The selected
address will depend on which forum the URL is to be published at. Within the same window, the link which allows access to the published screen from any internet connection
is provided.
The file links.txt, which is generated in the directory
usr/cype/cypecad contains the links of all the published

2. Templates
2.1. Template properties and options
2.1.1. Template fundamental properties
So to optimise the use of this module, CYPE has established a series of help proposals to define the job.
The elements to be introduced, such as the columns, external outline beams or beams defining openings in panels
should be drawn with different layers.
Fig. 2.2
Upon clicking on the Layer manager, the layers corresponding to the selected template will be displayed. These
layers can be configured: visible or not visible, name
change, colour modification, line thickness edition (if th
e
thickness is established as By size, it is possible to specify
its value); it is equally possible to leave layer texts visible
and allow object snaps on the entity of a layer.
The external outline beams and opening beams should
form a closed polygon.
It is possible to use a single layer to define the fixed point of
the columns. It will be represented by a closed polygon
containing the point of the column to be defined as fixed.
Each group should be defined by different templates or
layers when a complete template of the job is provided: columns_grd, columns_flrs, columns_roof, outline_grnd,…
To the right of the layer list, the results of the layer configuration of the template selected from the above list can be
viewed.
2.1.2. Template options
The Template views manager window can be accessed by
clicking on the
icon of the main window toolbar.
Fig. 2.1
To attach the DXF/DWG templates to the project, click on
the
button at the top of the window.
The list of imported templat
es will appear in the dialogue
box.
Fig. 2.3
CYPE

CYPECAD
Once the drawing templates have been imported, the program will return to the Template views manager where the
templates will be displayed with their respective layers.
Once the origin has been displaced, it is possible to return
it to its initial position, in other words, to the original position
of the drawing, by clicking on the
icon. This option was
brought about to be able to undo all the changes carried
out on the coordinates using the Change the origin of the
coordinates of a template option
.
To change the scale of the drawing when the scale value
is unknown, use the option Adjust the scale of a template
. The program will ask to graphically define the first
and second points of the segment as well as the distance
of the segment with a scale of 1:1.
The option Group views
allows to choose for which
groups the templates will be visible.
Fig. 2.4
Note: A view is a configuration of layers with the scale and c
oordinate origin of a DXF/DWG drawing. Generally, it will only be
necessary to create those views required as templates for each
group making up the project. Each view will be related to a template and will have a unique selection of layers.
Fig. 2.5
This option is equally accessible later on by clicking on the
icon
. However, in this case, contrary to the option window Group views, the window that opens only allows to
activate or deactivate the views per floor.
Within the top list of the Template views manager window, the available views can be seen as well as the Add,
Delete, Copy, Displace, Transformation, Group views,
Open and Save options located at the top.
By clicking on Transformation
, a window will open allowing displacements and scaled increases or reductions in
size to be applied to the template. The scaled and displacement transformations can be carried out in two different
ways: manually introducing the value within the Displacement and Scale fields, or graphically by
clicking on
to
change the coordinates or on
to vary the scale.

3. Groups and Floors
3.1. General information on groups
The program allows up to 5 floors per group.
A group is defined as an assembly of one or more equal
and consecutive floors and therefore, will contain the sa
me
reinforcement. Various aspects should be considered for
groups containing several floors:
Fig. 3.1
• Data introduction is the same for all the floors of the
group.
3.2.1. Creation of new floors
• The results that appear on screen correspond to the
envelope of all the floors belonging to the group.
Upon creating new floors, the program will ask whether the
floors to create are to be Grouped or Single.
• The design of all the floors of the group is the same.
• Therefore, a single drawing is obtained for the group,
i.e. a single floor plan, beam drawing corresponding to
a single group, etc.
• It is not necessary to regroup the floors unless a vertical
support (column, shear wall, wall) or sloped beam begins or ends at one of the groups.
Fig. 3.2
The number of floors to insert must be indicated, as well as
their heights, live load and dead load (screed, etc.). A more
specific name can also be given to each floor. The use category of the group is also to be indicated.
The use categories are defined separately (explained further down). If the
user has already defined the use categories of the building,
he/she will be able to select the use category for the group
from amongst those that had been defined. On the
contrary, if no use categories have been defined, only the
default option is displayed and the user may modify the use
category of each group later on
3.2. Floor and group introduction
Floor and group introduction is done using the option Floors/Groups from the Introduction menu within the Column Definition tab.
Unless a floor or group has been defined, the only visible
option will be New Floors. Later on, other options will become available. These include: Delete floors, Edit floors,
Edit groups, Join groups and Divide groups.
CYPE
CYPECAD - User manual
This way, the live load combinations for each use category
can be analysed correctly amongst all the use categories
and the remaining loadcases of the job for which different
use catego
ries exist per floor.
The use categories can be selected in the Additional loadcases (special loads) dialogue box within the General
data window (Job > General data > Additional loadcases (special loads)).
Fig. 3.3
3.2.2. Use categories
Different use categories can be defined for each floor
group of the structure. Examples of use categories include:
dwellings, shops, warehouses, garages, etc. The number
of use categories the program allows to choose amongst
depends on the selected code. For example, the use categories for the Eurocode are:
Fig. 3.4
• A. Domestic and household
The categories that are selected in this dialogue box are
assigned to each floor group in the Edit groups dialogue
box which opens by selecting the Loads menu within the
Beam Definition tab > Loads in groups or in the Column Definition tab > Floors/Groups > Edit groups.
• B. Offices
• C. Meeting areas
• D. Shops
• E. Warehouses
• F. Vehicle weight <= 30 kN
If a new job is created using the
automatic introduction process, the user will have to define the use categories once
the automatic introduction has concluded, then edit the
groups and select the use category. If the new job is being
defined without the automatic introduction assistant (empty
job), the user can choose whether to define the use categories before or after the groups are defined, in which case if
these are defined after creating the groups, the user will
have to edit them and assign the use categories.
• G. 30 kN < vehicle weight <= 160 kN
• H. Roofs
For the program, a use category consists of a group of live
loadcases, be they automatic or additional, which combine
with the other loadcases that have been defined in the job
with the same combination coefficients.
CYPE
27
28
CYPECAD
Fig. 3.6
Fig. 3.5
Different use categories can also be defined for a floor
group. To do so, simply do not introduce a live load for the
group and once the geometry of the floor group has been
defined, introduce
the live loads at different positions on
the group, assigned to the corresponding loadcase and
use category.
The user should bear in mind that the more use categories
are defined for a job, the more loadcase combinations the
program will create, and so, the time taken to analyse the
job will be substantially longer.

3.2.4. Creation, edition and deletion of groups
To group the floors, click on the option Join groups. This
option will allow to select the floors to be grouped.
3.2.3. Elevation of foundation plane
The elevation of the foundation plane can be indicated in
the Edit floors window. The elevations of all the floors are
automatically adjusted to the value given in the foundation.
Within this window, it is equally possible to modify the
names of the floors.

4. Columns
4.1. Definition of columns, shear walls or
starts
Having defined the starts, it will be necessary to introduce
the loads transmitted to the foundations by the columns
using the option Introduction > Columns, shear walls
and starts > Head loads.
To introduce a column, shear wall or start, click on Columns, shear walls and starts from the Introduction
menu within the Column Definition tab.
Before proceeding with the foundation design, the option
Analyse > Analyse the job from the Column Definition
tab must be
selected.
Bear in mind that if no floors have been defined, only starts
can be introduced.
Once a column, shear wall or start has been introduced,
the Columns, shear walls and starts menu will contain
more options allowing for them to be edited, displaced, adjusted, modify their fixed point, their angle, introduce fixity
coefficients, effective lengths, loads, etc.
If the foundation has been introduced, then select Analyse
> Analyse the job (including foundation).
4.1.2. Columns
4.1.2.1. New column
When introducing a new column, the initial group, final
group, fixity and buckling coefficients, angle, and external
fixity must be defined.
Fig. 4.1
4.1.1. Column starts
Starts are columns with zero height which are used to design the foundations (regardless of them being in the form of
a mat foundation, pad foundations or other) without the
need of having to introduce the whole structure and therefore, not having to define floor groups.
Fig. 4.2
CYPE
CYPECAD - User manual
Th
e type of column must also be defined for each floor. To
do so, click on the symbol located next to the floor numbers in the bottom section of the window. The program will
then ask to choose between a concrete or steel column.
Once the type has been selected, its dimensions must be
defined.
This option provides more possibilities as to the geometrical disposition of the columns within CYPECAD jobs. For
example, columns may be defined in such a way that, for
different spans, they are adjusted to different fixed points or
have different angles or dimensions which cause part of the
top span to lie within the projection of the column below.
The program allows for an infinite number of spans to be introduced over each other, in other words, a column can be
placed over another which, in turn, is placed over another,
etc. Additionally, more than one column can start on the
same column.
Fig. 4.3
Having defined the properties of the column and clicked
on Accept, the window will close and ret
urn to the main
screen where, the position of the columns can be selected
by clicking at the desired position.
Procedure
Once the option has been selected and the cursor is then
passed over a column, if it changes colour, it is possible to
introduce a column on top. This occurs when the column
ends at a floor that is not the last floor. To introduce a new
column over another, the program draws a concentric circumference with the axis of the column illuminated (this will
be the base column) on which it is possible to place the
fixed point of the new column.
4.1.2.2. New column with its start on another column
It is possible define the start of one or more columns on
another column using the option Introduce a column
with its start on another column. This option can be
found within the window that appears upon selecting Introduction > Columns, shear walls and starts.
To position the new column, left click using the mouse. The
program will ask for the coordinates of the fixed point o
f the
new column with respect to the fixed point of the base column. Having introduced the coordinates, a new window
will appear similar to that used for the introduction of the
normal columns, where the new column data will have to
be defined.
It is possible to introduce the top column using DXF or
DWG object snaps to snap to the axis, corners, or midpoint of the column faces and the faces of the base column. In these cases, the program will not ask for the coordinates of the fixed point of the new column.
Fig. 4.4
CYPE
33
34
CYPECAD
For the reference of the new column or columns that start
on a base column, the program uses the same reference
as the base column followed by a letter. The first column will
have the reference followed by the letter <>, the next
with the letter <> etc.
Fig. 4.5
Fig. 4.7
Do not forget that if the columns are not overlapping, the
column is to be introduced in the same way as any ordinary
column and not with this option as it is not a case
of a column starting at the top of another column.
Option specifications
The fixity coefficient of the top end of the column on which
the new column begins is not affected by the value in the
Fixity coefficient at last floor option (Job > General data >
button By position > button Column options). All those
elements supported by the column (top columns, beams,
slabs…) will be considered as being fixed by default, except at the top of the last column span where a fixity coeffi-

new column.
located in the option Groups > Show references in the
Beam Definition tab.
The transmission of forces from the top column to the bottom column is carried out bearing in mind the existing eccentricity. The user must evaluate the
need to provide a
construction detail to assure this transmission of forces.
It is not possible to modify the external fixity of a new column starting on another as it is not possible to have external fixity.
Fig. 4.9
4.1.2.4. Introduction of new columns using data from
another column
4.1.2.3. Column edition
Sometimes the case may arise that all or many columns of
a job possess the same properties as one another. For this
case, CYPECAD offers a tool that allows for a new column
to be introduced based on the properties of one that has already been introduced.
The column options can be modified in the menu Introduction > Columns, shear walls and starts > Edit.
They can be equally modified independently accessing the
options in the Columns, shear walls and starts window.
Within the New column window (Introduction > Columns, shear walls and starts > New column), a Copy
from button can be seen. Upon clicking on it, the New column window will close and those columns already introduce
d will appear on screen. Once one column is selected,
the New column window will reopen with all the data copied from the selected column.
For example, the fixed point of a column can be modified
directly from the Edit Column dialogue box or using the
option Modify fixed point present in the Column, shear
wall and starts window. This option allows to change the
fixed point of the column keeping the column’s original position.
Fig. 4.8
Upon selecting this option, a window will open where the
fixed point can be selected. All the columns requiring this
fixed point should then have it assigned to them.
The fixed point of all the columns can be visible whilst introducing beams and floors by selecting the Fixed point box,

4.2. Column results
The program keeps the data of the last column introduced
when introducing a new column, and so allowing a quicker
introduction in the case of similar or equal columns.
4.2.1. Column design
Once the job has bee
n analysed, those columns not passing all the code checks will be displayed in red. They
should be verified using the option Columns > Edit located in the Results tab.
Using the Copy option from the menu Introduction > Columns, shear walls and starts from the Column Definition
tab, it is possible to copy, as well as the properties that can
be copied using the option Copy from described previously, the horizontal loads and head loads of the column.
Having selected this option, click, using the left mouse button, on the column whose errors are to be consulted and a
window will emerge entitled Column design.
4.1.3. Shear walls
In order to introduce a shear wall, its geometry must first be
defined, which must be composed of rectangles. Other
data to be indicated includes: a name for the wall, its initial
and final group, followed by, in other windows, its thickness, external fixity and angle.
Once all the windows have been accepted, the wall can be
introduced at the desired point. The
types of shear walls
created are saved with the job and so can be introduced at
any time with no limit as to how many.
4.1.4. Column minimum geometric ratios
For each code and depending on the selected steel, there
are minimum values for the geometric ratios of the columns. These values are usually those applied by the program for column design and verification. Nonetheless, if
other values are required, it is possible to introduce them:
Job > General data > By position > Vertical bar options > Minimum geometric ratios for static and dynamic loading. These user values will substitute the minimum
ones from the code.
Fig. 4.12
4.2.1.1. Concrete columns
If several columns contain design errors, the following message will appear in the analysis report: “Columns (…) have
a design error. They must be reviewed using the option Columns > Edit”. The column section is also displayed in red
on screen at the floor at which the error is located.
Column errors
Within the Column design
window, those column spans
containing errors will have a warning symbol displayed on
the left. A status column can sometimes be viewed dis-

Only one stirrup is placed. Review the column reinforcement table and the layout of the stirrups when creating
the required types for the reinforcement and dimensions of the existing columns.
Fig. 4.13
• Vr: Volumetric ratio of stirrups
In the case of earthquake loading with very high ductility, the confinement geometric percentage is limited.
This percentage is the ratio between the mechanical
percentage of the stirrups and t
hat of the concrete, per
metre length of the column.
• SAe: Excessive ratio
The program considers the mechanical percentage
between the concrete and the steel in the columns
should not be greater than 100% and that the geometric percentage should not overcome 8%. If these values are exceeded, the letters SAe are displayed.
• fr: Fire resistance check
The program indicates if the section fails the fire check
according to what was specified by the user.
• Ve: Shear failure
The program checks that the shear force does not exceed the force that would produce oblique compression failure of the section in reinforced concrete columns and for those cases where it is stated in the selected code. When shear reinforcement is necessary,
the program also verifies the spacing required.
• As/Ac ratio
Within the Column design window, located in a column
on the right is the ratio of the steel section to the
concrete section expressed as a percentage.
Upon clicking on the button, a window
appears indicating the longitudinal area in the X and Y directions, the
reinforcement area of the stirrup, the forces in both directions as well as the resisted shear force in each direction.
4.2.1.2. Steel columns
If there are steel columns in the structure, a window offering
design options will appear. If the program is to design the
steel sections, the manner in which they are to be designed
must also be selected.
CYPE

CYPECAD
This includes indicating to the program whether it can design the section using all the sections of the series or using
sections greater than the current section. In the first case, if
the program finds a smaller section capable of withstanding the forces, this section will substitute the existing section. In the second case, CYPECAD will only use sections
that are greater or equal to the chosen section.
In the windows that opens, the line weight of the sections is
displayed as well as the ratio (%) of the resisted force to the
design yield stren

4.2.1.4. Column layout
When re-analysing the job, the program will carry out a
check on all the blocked columns ensuring that all the
conditions of the selected code are met. Those failing a
check will be displayed in red.
This button provides a layout of the columns of the selected or selected floors. If there is a column that has not been
des
igned, (manual reinforcement), it will be displayed in
red.
If significant errors appear in a blocked column after a new
analysis, they imply that the changes undertaken on the job
after the reinforcement has been blocked, substantially affect the columns. It is therefore recommended the column
reinforcement be redesigned.
There are two options to redesign the columns: unblock
them and then redesign (Beam Definition tab, Analyse
> Redesign columns) or keep the columns blocked and
use the Redesign option in the Column design window of
each column (Results tab, Columns > Edit).
Fig. 4.18
When modifications have been carried out implying an increase or decrease in the number of floors supported by a
blocked column, the program will automatically unblock it.
The column selected from the Column design window is
marked with a yellow circle. By clicking on another column,
the yellow circle will appear on that other column and if the
Column layout window is closed at this point, the colum
n
displayed in the Column design window will be the newly
selected column.
Unlike what occurs with blocked frames, the program undertakes a complete code check on all the blocked columns. Therefore changes made to the structure after
blocking the column reinforcement are not as conflictive.
The blocking of columns is a very useful tool to have for different project situations, for example, to study how the column reinforcement varies depending on the applied fixity
coefficient; subgrade modulus; jobs with mat foundations;
etc.
4.2.2. Block column reinforcement
The option Block reinforcement allows for the structure to
be re-analysed without modifying the column reinforcement. This tool is located in the Column menu within the
Results tab.
This option is only applicable to reinforced concrete columns, the equivalent option for steel columns can be produced if, upon selecting to analyse the job, the Design
steel sections box is left unmarked.
4.2.2.1. Things to consider when using

Within the generic block walls, Series editor window, it is
possible to activat

corner elements are to be used when the width of the block
is not equal to half its length. This way, the special corner
elements allow for a faster construction of the wall.
5.1.2.3. NORMABLOC walls
Fig. 5.6
Prefabricated concrete walls are a traditional solution due
to their properties. They can act as load bearing walls (resisting horizontal and vertical loads) as well as providing
partitions or enclosing spaces where required.
NORMABLOC walls do not have the option With corner
element, although the program is aware if the manufacturer and selected block model have these special elements
available and will use them, if necessary.
It is possible to design and check existing concrete blocks
(and those of manufacturer companies as in the case of
the Spanish group NORMABLOC: National Association of
Masonry and Concrete Block Manufacturers), optionally
provide vertical and/or horizontal reinforcement, all this respecting the criteria imposed by Eur
ocode 6 (Masonry design and construction. Part 1-1. General – Rules for reinforced and unreinforced masonry). Provision of analysis reports, takeoff and floor drawings as well as a diagram on
plan of the blocks and their reinforcement.
5.1.2.4. Masonry walls
This option allows generic walls to be introduced.
Within the General data window of the Job menu and
upon selecting the wall icon
, it is possible to define the
modulus of elasticity, shear modulus, unit weight, design
compressive strength, design tensile strength and whether
or not to consider shear stiffness, required in the case of
masonry walls resisting horizontal shear (produced by horizontal loads) and tension (in the case of walls supported by
floor slabs and connected to higher floors).
In the case of NORMABLOC blocks, it is only necessary to
select, using the option Block from the dialogue box, the
manufacturer and the type of block to be used.

To introduce the openings at their correct positions, the
floor viewed on screen must be the lower of the two floors
between which the window or door is located. For example,
if a door is to be introduced in a wall between floors 1 and
2, the introduction floor must be floor 1.
In the case of openings in concrete block walls, when using
the Wall openings option, it is pos
sible to adjust the opening within the block distribution of the wall. This way, the
dimensions and position of the opening will adjust themselves to the length of the block so to avoid having to provide special pieces.

During the reinforcement design process of concrete walls,
the reinforcement of the openings (windows and doors) within the walls is designed. This reinforcement is designed to
support any lateral pressures, forces at door and window
lintels and at window sills.
For those cases where the wall is subject to seismic loading and the acceleration is greater than 0.16 g, inclined
reinforcement is laid in the lintel and sill.

Adjustment of the beam
The use of the option is helpful in the following case: the
edge of the beam limiting the floor slab is, generally, shifted
a few centimetres due to coatings or other elements of the
façade. Usually, the lines drawn on the DXF or DWG templates are those representing the façade outline and not
the structural floor slab limits. In all cases, the introduction
line will not coincide with the adjustment line and will lie outside the width of the beam.
This option allows for the beam to be adjusted to along its
central axis or to one of its sides, in other words, change
the adjustment line of the beam.
Fig. 6.4
To understand this definition, two concepts used in the program must be explained:
Straight and curved beams
The shape on plan (straight or curved) of the beam to be introduced can be selected here. Upon clicking on this button, the four available options appear (unless the simple
beam option is activated, in which case, only the first two
options
will be visible).
• Adjustment line of the beam. This can be the axis or either edge of the beam. It is the reference line used by
the program from which the distance is measured to
the introduction line. This distance is indicated in the
Move option.
• Introduction line of the beam. This is the line that is marked with the mouse pointer during the introduction of
the beam. The Adjust and Move options vary the position of the beam relative to the introduction line.
Fig. 6.6
• Straight beams. The initial and final points of the beam
have to be marked using the left mouse button.
Changing the adjustment line can be done equally with the
shortcut. Similarly, if the adjustment is to be changed during the introduction of the beam, all that has to be done is
displace the mouse to the beam introduction menu. By
pressing Ctrl + E, the adjustment type will change cyclically.
• Curved beams. Using the left mouse button, three
points have to be marked defining the initial, passthrou
gh and final points of the curve. By pressing Ctrl +
A, the beam introduction changes from curved to
straight and vice versa. What the program is really drawing is a series of straight beams forming a polygon
adjusted to the outline of the circumference defined by
the three marked points. With regards to the introduction and adjustment lines, these work in the same way
as in the case of straight beams, except that in this
case, they can be considered as curved lines.
Beam displacements during the introduction
This option establishes the distance between the introduction line and adjustment line defined in the previous paragraph.
• Alternate introduction of straight and curved beams.
When the continuous beam introduction is activated, a

this problem is encountered, it is recommended that the

the option Beams/Walls > Define wall.
straight and curved spans can be alternated. Two options appear in the menu: one beginning with a straight
span and another with a curved span. This option can
also be accessed using Ctrl + A.
6.1.2. Beam types
The crown beam at the top of the wall cannot be specified
with the program. Consequently, the user must provide a
construction detail with the dimensions and minimum reinforcement for this element. Consult the construction details
library supplied with the program.
When introducing a new beam, the Current beam window
opens where the type and properties (dimensions, section,
shear studs, etc.) of the beam must be chosen. The following beam types are those that available in CYPECAD:
Flat beams
Non-structural or limit beams
Flat beams are those possessing a thickness equal to the
elevation difference betwe
en the highest and lowest points
of the floor slab they form the outline of.
This option is used to define the outline perimeter for a solid
slab panel when the influence of the edge beam with respect to the force resistance is negligible or is not to be
considered. Its function is simply to limit the border of the
panel. On site, if a beam is to be used to carry out this function, a generic edge beam detail of the beam to be used
should be provided.
Dropped beams
Dropped beams can be rectangular, T-shaped and with a
contributing compression head. In the latter case, the
flanges contribute to the stiffness of the beam, but, for reinforcement calculations, only the web is used. This is a
common way to model flat slabs framed by dropped
beams.
Foundation beams
Foundation beams can be rectangular, L or T, or flat beams
(the latter are used to close off panels in mat foundations).
Latticed and prestressed beams
Steel and composite beams
The properties of latticed and prestressed be
ams are defined by clicking on the icon that appears in the top right
corner of the selected window.
• Steel beams. Steel beams can be introduced as composite beams, welded in a box, separated with batten
plates or joined, etc. The same section library is available as for steel columns.
External fixity beams
External fixity type beams can simulate, for example, the
top of a wall. If the path of the walls coincide with the columns, they must be disconnected using the option Beam/Walls > Pin/Disconnect so that the vertical movement of the columns is not restrained by the walls. Note
that walls may only be disconnected from columns in joist
Castellated steel non-composite beams can be designed and verified. Within the Layout drop down menu
in the Description dialogue box, the Castellated (web

ning (hexagonal, octagonal or circular), the dimension
ratios and the number of filled openings at the ends of
the beam.
• Composite beams. It is possible to introduce (type 1)
steel sections below the floor slab with a contributing
concrete head by means of shear studs, whose geometry can be defined.
6.1.4. Polybeams
This option can be found in the Beams/Walls menu from
the Beam Definition tab.
A partial fixity coefficient of 0.05 is applied to the
connection of the composite beam with its support (in
the same way as the column heads of the last floor)
with the aim to reduce the negative moment and increase the positive moment.
For CYPECAD, a Polybeam is an assembly of consecutive
beams grouped in such a manner that if one undergoes a
geometrical change, all the others in the group will also
change. In a similar way, if one beam of the assembly is deleted, all the ot
hers will also be deleted. Nonetheless, the
reinforcement of each beam can be different.
Composite beams are designed so that in the negative
moment zone, the steel section resists all the forces
and in the positive moment zone, the composite section withstands the forces.
This option has great similarity to that of the curved beam
introduction option. A curved beam is composed of several
straight beams that change direction. If the properties of a
curved beam are to be changed, each of the straight
beams must be modified individually. To simplify the problem, it is best to group the straight beams and make a
Polybeam.
With regards to the moment calculations; it is not necessary to indicate the width of the contributing
concrete section. The program takes the minimum between the calculated effective width and the width of the
flange plus 10 cm for each side, if it does not consist of
an edge beam, otherwise, the program calculates the
width of the flange plus 10 cm.
Even though it
is not always useful, the Polybeam option is
in most cases. This is because the Polybeam option allows for other options to be used to vary the groups regardless of it being straight or curved.
To verify the positive moment sections, the effective
width is different to that taken for the bending analysis.
Therefore, in the beam editor, the width that appears is
that of the effective width in the negative moment zone
in case reinforcement is added at the supports, which
is not designed by the program in the present version.
The beams forming a curved beam are by default grouped
as a Polybeam. Using the Polybeam option from the
Beams/Walls menu, the beam can be decomposed or
modified. The beams forming a curved beam are by default grouped according to a Predefined reinforcement
span. This option, present in the Beams/Walls menu, also
allows to decompose the group.
6.1.3. DXF or DWG object snap during beam introduction
It is possible to adjust the beam with any of the DXF or
DWG objec
t snaps available (nearest, intersection, end,
mid-point, etc.) The adjustment is carried out during the introduction of the points making up the simple or contiCYPE
CYPECAD - User manual
6.1.5. Predefined reinforcement spans
• Simple. The program generates a single sloped beam
between the selected initial and final floor groups.
A Predefined reinforcement span is composed of an assembly of consecutive beams in which the bottom reinforcement does not overlap at an intermediate point of the
group. This will be applied for every group of beams whilst
the length of the steel bars do not exceed the maximum
bar length established in the program options.
• Multiple. A sloped beam is generated for each floor between the selected initial and final floor groups.
The reason for the existence of Predefined reinforcement
spans is the same as that given previously to justify the
existence of Polybeams. This allows to simplify beam reinforcement construction.
Even though the Predefined r
einforcement spans option is
useful in most cases, it is not always. This is because the
Predefined reinforcement spans options can be decomposed into various options allowing to vary the groups regardless of the beam being straight or curved.
Fig. 6.8
6.1.6.1. Diagonal braces
The composition or decomposition of the Polybeams and
Predefined reinforcement spans, which imply a change in
the number of beams making up the alignments (frames),
is useful to view the designed reinforcement. In order to obtain the new reinforcement, it is only necessary to redesign
the frames using the options in the Analyse menu.
Using the option Beams/Walls > Sloped beams > Add
diagonal braces, diagonal braces can be introduced and
then carry out other operations with them.
6.1.6. Sloped beams
For steel or concrete sloped beams. It is possible to generate a beam for each floor between the selected initial and
final floor groups.
Fig. 6.9
The window contains the following options:
• Initial and fin
al group. Floor groups at which the
brace begins and ends. These groups should have a
single floor. Nonetheless, the diagonal brace can go
through intermediate groups containing more floors.

at which the diagonal starts at is left on screen. The
braces drawn on screen may look horizontal, but this is
not the case. Two arrows are drawn within the bar indicating each diagonal.
• Simple. The program generates a single diagonal
brace between the selected initial and final groups.
• Multiple. A diagonal brace is generated at each floor
between the selected initial and final groups.
As additional information regarding diagonal braces, it
is convenient to know that a node is generated at the intersection of the diagonals and that these are designed
for tension as well as for compression. For this reason,
they generally present a slenderness problem, given
that the program verifies that the slenderness of the bar
does not overcome the maximum slenderne
ss (defined
in the code) for those elements in compression.
• Type. If a simple beam is selected, the user must indicate whether it is a concrete or steel beam. If a
concrete beam is chosen, the width and depth of the
beam must be specified, otherwise, the steel section to
be used must be selected from the section library. In
the case of a steel beam, a further option is provided
whereby it may be placed transposed or upright.
• Connection at ends. It is possible to indicate whether
the connection at the ends of the brace is a fixed or
hinged connection.
Once a diagonal brace has been introduced, new options will appear in the Sloped beams dialogue box:
• Buckling coefficients. These are required for sloped
steel beams or for steel diagonal braces. The coefficients introduced are multiplied by the complete length
of the beam between nodes. Therefore, in the case of
two sloped beams intersecting at a point, the program
will not take this intersection into account.
The vertical
and transverse buckling coefficients are established with respect to a vertical plane containing the
bar and the Z axis of the structure and its transverse
plane, not in the local axes of the bar.
Fig. 6.10
• Delete. Deletes the selected diagonal brace. In the
case of the generation being multiple, they are deleted
in all the groups.
• Copy from. If the user wishes to introduce diagonal
braces based on others that have already been introduced previously on screen, click on this option. Having
done so, click on the diagonal brace to be copied and
the window containing the properties of the selected
brace will open.
• Information. It is possible to know the type of diagonal
brace, the initial and final groups, real length, type of
section, connections and buckling. The result is also
drawn on the beam drawings of the group corresponding to the initial group.
• Add. Allows to introduce a diagonal brace. The two
end points of the diagonal have to be indicated for its
introduc

one of the diagonals starts and then on the opposite
beam, where it ends. Upon carrying out this operation,
an automatic floor jump is not produced, only the floor
• Edit. Allows to modify the data introduced for the diagonal brace. When editing the diagonal brace, regardless of whether or not it was a multiple introduction, it is
only edited in the current group.
• Move. Allows to displace the ends of a diagonal brace.
CYPE

It is possible to create a common beam for half the length
of the beam, by selecting either end of the beam. Each part
can be common to different groups.
When displacing the diagonal brace, regardless of
whether or not it was a multiple introduction, it is only
displaced in the current group.
• Assign diagonal braces. This option allows to copy
the properties of a diagonal brace to one or more diagonal braces that have previously been introduced. The
window that appears is similar to
the Add diagonal
braces window, except that in this case, as it has been
explained previously, its function is to modify the properties of beams that have already been created. Upon
assigning a diagonal brace, regardless of whether or
not it was a multiple introduction, it is only assigned in
the current group.

Option Beams/Walls > Common beam > Undo common beam. Splits a common beam into the two original
beams. This must be carried out on the associated beam.

supporting a horizontal slab which meets an inclined slab.
The beam supporting the slabs is a Common beam. The
beam is only introduced in one of the two groups. Select
this option and click on a beam; the program will then ask
for the common group to be selected. On doing so, the
beam will automatically be created in the group. The axis of
this type of beam is drawn with a discontinuous dash-dot
line. To undo a common beam, it is first recommended it be
deleted from the associated floor group, if not from the
group in which it was first introduced.
• Introduce rectangular external edge with 0 angle.
The two opposite corners of the rectangular opening

By clicking on the right mouse button, if sloped planes have
been introduced previously, an option appears allowing for
the beams to be adjusted to the intersection of the sloped
planes or the maximum slope line. The adjustment of the
planes to the intersection is necessary so to ensure the axis
of the beam separating two floor panels, of which at least
one is a sloped plane, coincides with the intersection of the
planes of these floor panels. This intersection is represented by a continuous magenta line if it does not find any
beam axes and a discontinuous magenta line in the opposite case. The axis can be adjusted to the maximum slope
line, in which case, it will be represented by a continuous
magenta line on
the beams belonging to the sloped panels
where the direction is not parallel to the maximum slope
line. This line passes exactly through the centre of the
beam (relative to its thickness and width). To adjust the
beam, it must be clicked on.
6.1.11. Corbels
These allow for a beam to be supported on a column indirectly to represent expansion joints. They should not be

6.1.13. Beam reinforcement within walls and crown
beams
1. First introduce a regular beam up to the face of the column.
2. Select the corbel to be introduced and define its type
and geometry (the dimensions of the support area
must also be specified here).
The possibility exists to optionally reinforce the beams at
floor panel level and generic masonry walls and concrete
block wall crown beams. In the case of basement walls, the
beam is reinforced at the top of the wall.
3. Click on the fac
e of the column or columns in question.
In the window Beam reinforcement within walls and
crown beams located by clicking on Job > General data
> By position > Beam options, it is possible to indicate
whether or not to reinforce the beams for the different types
of walls. The minimum thicknesses of these beams should
also be indicated.
At the centre of the support, the program will internally
place a fixed support in such a way that the beam continues up to the support and only the vertical load is transmitted to the corbel. The beam is automatically disconnected from the face of the column (any shear or moment is
not transmitted).

the case of assembly reinforcement and the first layer of
bottom reinforcement, the diameter, number of bars and
anchorage length. For the remaining longitudinal bars, the
diameter, number and length of the bars are copied. In the
case of stirrups, their diameter, separation and reinforcement length are copied. Having copied the frame, it is recommended the reinforcement be checked in case the
reinforcement laid out has been reduced with respect to
what was required, as the program does not warn of this
when it is copied.
6.2.6. Frame grouping
The frame onto which the reinforcement is t
o be assigned,
must comply with the following conditions:
Within the Beams/Walls menu in the Results tab, the option Group frames can be found, which allows for frames
to be grouped amongst themselves. This is done after the
job has been analysed. If the grouping is not possible, the
program will warn of this and provide a reason.
• All spans must be of reinforced concrete.
• All spans must be of the same type. For example, it is
not possible to copy the reinforcement of a flat beam to
a lattice beam, however it is possible to copy the reinforcement from a flat beam to a dropped beam.
This option does not undertake any checks regarding the
conditions of the grouped frames.
• The beams must contain the same number of spans.
Any modifications carried out on one frame will affect all the
others in the group.
• Any difference in span length must be less than 25 cm.
• If there are any elevation changes, their elevations and
positions must coincide.
In the beam drawings, a
single frame will appear per group,
indicating all the references belonging to the grouped
frames. The option, Ungroup frames, performs the opposite process.
If for one of the previous reasons, it is not possible to copy
the reinforcement of a frame onto another, the program displays information explaining the cause of the failure.
Finally, the option Add frame to grouping allows for new
frames to be added to a previously established group.
On the other hand, copying of reinforcement between
frames does not imply that the beam drawings will all be
the same; this will only be the case for those whose geometry is exactly the same.
6.2.7. Block frame reinforcement
The option Block frame reinforcement allows for the
structure to be analysed maintaining the reinforcement of
those frames that are selected before the analysis. This tool
can be found in the Beam/Walls menu in the Results tab.
6.2.5. Design of steel beams
Once the structure has been completely analysed, the option is av
ailable to design the floor steel beams.
CYPE
CYPECAD - User manual
6.2.7.1. Things to consider when using this option
If significant errors appear in a blocked frame after a new
analysis, it implies that the changes undertaken in the job
after the blocking of the frame reinforcement substantially
affect it and therefore it is recommended it be unblocked
and reanalysed. When the program is reinforcing an unblocked frame, the program carries out all the checks stated in the selected code (bar spacing, anchorage length,
etc) using the forces obtained in the last analysis.
The option Block frame reinforcement has been brought
about so not to loose the manual modifications of the
frames due to the job being reanalysed or due to minor
changes. This option does not intend to verify the frame
reinforcement.
If, once the reinforcement of the frames has been modified
manually, it is necessary to carry out small changes on the
structure and therefore re-launch an analysis, any manual
modi
fications made to blocked frames will not be lost.
The option Block frame reinforcement can be used to
maintain the reinforcement of those frames whose groups
have not undergone any changes or whose modifications
are insignificant.
The program offers two options to redesign the blocked
frames: Redesign all the frames or Redesign frames with
changes (available in the Beam Definition tab, Analyse
menu). This last option proves to be a useful tool as the
program only redesigns the reinforcement of those frames
that have been unblocked and those whose section has
been modified.
If the changes in the job imply a change in the number of
spans of a frame, it will automatically be unblocked.
6.2.7.2. How the option works
All these considerations should be taken into account by
the user to decide which is the best solution.
Those frames that are not blocked will be undergo the reinforcement design process each time the job is reanalysed.
Having selected the Block frame reinforcement optio
n,
the Frame selection window will appear.
Warning
Be aware that after a new job analysis, the program will
only check if the reinforcement provided (blocked reinforcement) in the blocked frames possesses the required
steel area and if the deflection conditions are verified. The
remaining checks are carried out in the regular design process (as in the case of unblocked frames). After a new analysis, any blocked frames not verifying the aforementioned
conditions will be displayed in the colour configured for
beam errors. The user should consult the reinforcement
containing errors (Results tab, Beams/Walls > Edit beams) and decide whether, to resolve the problem, a small
modification to the reinforcement is sufficient or if the frame
should be unblocked and the reinforcement redesigned.

Jobs containing panels awaiting definition cannot be analysed and so there is less probability of the user forgetting to
define a panel before the analysis.
The user can create, copy, delete, etc., generic panel types,
for use when the panel that will finally be used in the job is
unknown, as well as being a practical aid as to establish
whether the joists to be used will be reinforced or pres
tressed joists due to their deflection.
The panel awaiting definition is displayed in the 3D views.
This allows the user to have a 3D view in which openings
and slabs can be seen before the final type of panel has
been introduced.
When creating or editing a concrete joist floor slab, the following data will have to be entered:
• Reference. Panel description.
7.1.2.2. Joist floor slabs
• Compression layer thickness. Thickness of the compression layer above the form.
Depending on the selected code, various types of joist floor
slabs can be introduced.
• Form depth.
• Rib spacing. Distance between the axes of adjacent
joists.
• Rib width. The minimum thickness of the joist is to be
indicated here.
• Rib width increment. This increment refers exclusively
to the thickness of the intermediate walls of the forms
for the calculation of the stiffness and cracking moment
when calculating the deflection. This is only considered
when using concrete forms.

modify this value by activating the box and introducing
the corresponding value.
These are prefabricated joists whose data sheets or authorisations have been provided by various manufacturers.
CYPE does not assume any responsibility for the data provided and so, it is recommended these be verified before
use. Nonetheless, a logical control has been carried out on
the data introduced. On the other hand, in those cases
where the user wishes to introduce data belonging to another manufacturer, it can be forwarded to us and we can include it in the program, or, alternatively, a new data sheet
can be created using the Panel data sheet editor program.
• Type of form. The program allows to select between a
concrete, terra-cotta, polystyrene or generic form to be
used. Based on all the parameters introduced at thi

stage, the program calculates the total weight of the
panel per square metre (volume of the concrete plus
the forms). When generic forms have been used, their
surface weight must be indicated by the user.
• Deflection Code check. Depending on whether the slab
built on site is composed of reinforced or prestressed
joists, the type of joist has to be indicated so the program may calculate the deflection accordingly, as the
cracked stiffness in these cases varies greatly (the case
may occur where the cracked stiffness is practically
equal to the gross stiffness, due to the prestressed effect, and so, the cracked stiffness/gross stiffness ratio
should be consulted with the manufacturer).

according to the outdated EH-91 and EP-93 codes).
The resulting design service moment is compared,
depending on the environment defined for the joist
(using the option Slabs > Panel manager > Environment) to that of the sheet, and if it is smaller, it is
accepted. On the contrary, a joist is found verifying

7.1.2.4. Hollow core slabs
Composite slabs consist in a steel deck profile collaborating with the concrete slab and with top and bottom reinforcement. The steel deck profile can be used to work in one
of the following ways:
Hollow core slabs may be imported from CYPE’s library or
created by the user. Upon creating a new slab the program
will require an amount of data to be introduced. T
o aid the
user in its introduction, a book icon can be located in the
top right hand corner of the dialogue box, providing information on what is to be defined.
• Form deck. During the construction phase, the deck
alone resists its dead load, the weight of the fresh
concrete and the construction live loads. During the service phase, it is only the reinforced concrete slab that
has a resisting function.
Some manufacturers propose various ways to position
the deck: ‘n’ or ‘u’, depending on the properties sought
by the user. ‘n’ represents the normal position whilst ‘u’
the inverse position. Once the composite slab has been
introduced on screen, a discontinuous line will be
drawn at the deck panel overlap axis, where the width is
that indicated on the data sheet.
• Composite deck. During the construction phase the
deck works as lost formwork. During the service phase,
the deck is considered to combine structurally with the
hardened concrete, acting as reinforcement
in tension,
resisting the positive moments in the finished floor slab.
The deck is capable of transmitting shear stresses at its
interface with the concrete as long as a mechanical
connection is provided by deformations in the deck
(embossments).
