CYPECAD - Practical examples
Presentation
CYPECAD is the software for rein
forced concrete, steel, timber and aluminium structures which
provides the spatial analysis, structural element design, reinforcement and section edition, and construction drawings of the structure.
It carries out the analysis of three dimensional structures composed of supports and floor slabs,
including their foundations, and the automatic design of reinforced concrete, steel, timber and aluminium
elements.
With CYPECAD, the engineer holds a precise and efficient tool to resolve all the aspects related
to the analysis of the structure of any type of concrete as well as being adapted to the latest international
Codes.

15. Practical examples
15.1. Introduction
15.2. Example 1
Two practical examples are described below. Each example is approached in a different manner. There is no single
correct way to introducing a job. With practice, the user will
develop his or her own method of introducing and analysing a job. Nonethele
ss, the objectives of both the examples are to:
In this example, a reinforced concrete structure composed
of columns, beams and joist floor slabs is to be introduced.
• Act as guides as to how the data of the structures
should be organised.
• Show how they are to be introduced in the program.
• Analyse their results.
• Obtain the necessary drawings and reports.
Fig. 15.1
N.B.: A more advanced course is available, published by
CYPE : Practical course of CYPECAD, which can be studied once this example has been worked through.
The following practical example is included with the program. To access it and install the DXF file to be used as a
template for the data introduction, follow the following
steps:
CYPE

CYPECAD
• Open the program
• Their respective sections with their pre-designed
heights.
• Click on File > File manager. The file manager window will open.
• Angles
• Click on the Example button.
• Fixed points.
The File manager window will ope
n displaying the job
file at the following directory: \CYPE Ingenieros\
Examples\CYPECAD, which will be opened later on
during the example.
Please recall that the fixed point of a column is the corner,
mid-point or axis from which the transverse section can be
incremented. This point is defined so avoid the marked limiting boundaries of the structure to be surpassed and so to
not invade openings. The user must know which column
faces cannot be moved.
15.2.1.2. Building elevation section drawing
This drawing should contain:
• Floor numbering
• Floor group assignment
• Surface dead and live loading
Fig. 15.2
• Difference in height between top elevations of finished
consecutive floors
15.2.1. Data organising
15.2.1.3. Floor table
15.2.1.1. Column layout drawing
Based on the previous drawing, the following table can be
created:
A drawing of this type should be created, which should display:
• The start and end elevations of each vertical column alignment, shear wall an
d wall.
CYPE
CYPECAD - Practical examples
15.2.1.4. Floor plans
It is convenient for the type of floor, depth, materials, partition loads, stair loads, local surcharges, joist layout direction, etc. to be known beforehand by the user to increase
the efficiency of the data introduction.
Fig. 15.3
• In the next window (New job window) the program will
ask the user to choose the introduction mode amongst
various options. Select Empty job (for this example)
and click on Accept.
15.2.1.5. DXF or DWG template
Once the floor and column outlines, fixed point of the columns, etc. have been drawn, the building geometry can be
introduced much more quickly with the aid of a DXF or
DWG template in which these elements are already drawn.
Although other methods can be used.
Use of the DXF or DWG as a template is an advantage
compared to introducing the columns using coordinates or
other methods (relative dimensions, layout lines or outlines). It also proves to be useful for edge beams and
stair
opening beams, patios, lifts, building services, etc.
If a DXF template is to be used, before exporting the file
from the CAD program, please ensure the number of decimal places is set to 3.
Check the units of the drawing before importing it into the
program and ensure it is in the same units and order of
magnitude as the program.

15.2.2. Data introduction
15.2.2.2. General data
15.2.2.1. Job creation
Having accepted the previous windows, the General data
dialogue box will open. Here, a description of the job may
be introduced, the codes to follow selected, materials to be
used, horizontal loads to be applied, definition of load factors and additional loadcases, column effective length factors, edition of reinforcement tables and analysis options.
Follow this process to create the job:
• Click on File > New. In the window that opens introduce the name of the job and click on Accept.

15.2.2.2.1. Code and materials
The concrete, rolled-steel, cold-formed steel, wood, masonry and composite slab codes can be selected, as well
as the type of concrete for each element of the job. The
type of steel to be used for the reinforcement bars can also
be defined.
• Click on Symmetry criteria. Introduce 300 in the window that appears and Accept.
For this example, the concrete to be used will be C25/30,
steel for bars S-500 and for the codes, select the corresponding Eurocodes for each material by pressing on the
Codes button at the top of the dialogue box.
Fig. 15.8
• From the options window select Continuity criteria.
Select Apply from the next to last from the scroll
menu for the option The number of bars in the faces
must be greater than or equal to that of the higher
floor. Accept this option, Exit the Vertical bar options
window and the program will return to the General data window.
Using the By position button
, the reinforcement tables
may be accessed and ma
ny analysis options can be edited and modified by the user.
In this example, columns will be designed in such a way
that all four faces will contain symmetrical reinforcement
and be continuous. Follow the steps to apply this arrangement:
• Click on the By position button
• Click on the Vertical bar options button
CYPE
CYPECAD - Practical examples
15.2.2.2.3. Additional loadcases (special loads)
The use categories for the building are to be defined here.
Click on the Additional loadcases (special loads) button
and then on the use category icon. Select A.Domestic and
household and H. Roofs from the emerging window and
accept.
Fig. 15.9
• To define the allowable bearing pressure of the soil,
click on the Foundation data button
.
• In the emerging window, introduce an allowable bearing pressure of 0.20 MPa for persistent situations and
0.30 MPa for accidental situations.
Fig. 15.11
Fig. 15.10
The additional live loads of this example are introduced without the need of h
aving to define an additional loadcase.
Nonetheless, if other loadcases are to be created in another job, be they compatible, incompatible or simultaneous
with other loadcases, click on the Additional loadcases
(special loads) button.
15.2.2.2.2. Wind and earthquake loading
We recommend that a first analysis be launched with only
vertical forces applied so that a general adjustment of the
columns can be carried out. In the second analysis, the horizontal forces can be applied, if any, followed by the adjustment of all the resistant elements. In the case of an experienced user, predesign the columns so that only a single analysis is required.
15.2.2.2.4. Limit states (combinations)
The limit states (combinations) can now be defined:
• Click on the Limit states (combinations) button in the
General data window.
In this practical example, no horizontal loads will be introduced.
• From the scrolling menus in the Limit states window
which appears, choose the Execution control, Use
category and Snow level for the job.
CYPE

15.2.2.3. Floor / Floor group definition
• If special combinations are to be defined for a specific
material, click on the Configure combinations for
each limit state button at the bottom of the Limits
states window.
Floors and floor groups are defined as follows:
• Click on Introduction > Floors /Groups
• In the new window, select the button corresponding to
the option whose limit states are to be modified.
• Click on New floors in the emerging window
Fig. 15.13
• Click on Single and click on Accept.
Fig. 15.14
• Introduce five floors and press the Enter key. Complete
the table and click on Accept.
Fig. 15.12
15.2.2.2.5. Effective length factors
Leave the default coefficients.
If the structure is analysed with vertical forces, a value of 1
for these parameters provides results with an applied safety factor. If there are horizontal loads acting on the structure, this value is also reliable as long as t
he analysis is
carried out taking into account second order effects.
Fig. 15.15
• The Floors and Groups window will appear again but
this time with more options.
Fig. 15.16
CYPE

• Group the second and third floors. Select Join groups.
A new window will open to join the groups.
• Move the mouse cursor and click to select which floors
are to be grouped.
Fig. 15.19
• Click Edit groups and change the name of Floors 2
and 3 to 2nd and 3rd floors.
Fig. 15.17
• Click on Accept. From the dialogue box that appears,
either option can be selected as no floor geometry has
been defined yet (this option is intended for use if the
floors are grouped once their geometry has been defined and differs between the two floors. Upon grouping
them, since they both have to contain the same geometry, the program prompts as to which geometry of
the floors is to remain).
Fig. 15.20
15.2.2.4. Import DXF or DWG templates
Fig. 15.18
As mentioned previously, the
use of a DXF or DWG template is very useful when introducing the geometry of the
structure. To import the DXF or DWG file:
• Click on Accept and the Floors and groups dialogue
box will reappear.
• Select the Edit templates button
from the toolbar.
The Template views manager window will open.
• Click on Edit floors and introduce –0.90 as the value
for the Elevation of the foundation plane.

15.2.2.5. Column introduction
The columns will now be introduced.
• Click on Introduction > Columns, shear walls and
starts from the menu in the Column Definition tab.
The following dialogue box will open.
Fig. 15.23
• Click on New column. For the time being, all the columns will be introduced with the same dimensions
from the Foundations to the Lift machinery roof. Therefore, accept the data that appears in the window.
Fig. 15.21
• Click on the Add icon and the Selection of templates
to read dialogue box will open asking for a DXF or
DWG file to be sele
cted. Find the floor_geometry.dxf
file located in \CYPE Ingenieros\Examples \CYPECAD\. Select and click on Open.
• Click on Accept to return to the Template views manager.
Fig. 15.24
• Upon accepting, the dialogue box will close and return
to the main screen. Using the scroll wheel of the mouse
or by opening a zoom window using the icon in the toolbar at the top of the screen, zoom in, so to view the first
column in the DXF template.
Fig. 15.22
• Click on Accept once again, to be able to view the template on screen. Upon doing so the program will ask:
Would you like to assign the view to all the
groups? Choose Yes.
For this example, a template has been created (with a CAD
program) to be used for the floor geometry.

• Click on the bottom left hand corner. The corner of the
column has been snapped. However, the position of the
column that has been introduced does not coincide
with the column from the template.
Fig. 15.25
Fig. 15.28
â€
¢ Click on the Template object snaps
icon in the
toolbar at the top of the screen. The first column to be
introduced is a corner column, therefore the fixed point
of the column will be the bottom left hand corner of the
column.
• To adjust the column, click on the right mouse button.
The New column window will open. Click on Cancel
and the Columns, shear walls and starts dialogue
box will appear.
• In the Object snap selection dialogue box that opens,
mark the Intersection box then click on Accept.
Fig. 15.26
• Place the mouse cursor over the bottom left hand corner of the column (its fixed point, marked on the template with a red circle). Notice how a cross appears
when the mouse cursor is moved over two intersecting
lines.
Fig. 15.29
• Click on Edit followed by a click on the corner column.
In the Edit dialogue box, a diagram of the Fixed point
of the column is shown in the top right hand corner. The
possible fixed points of the column are displayed in
green, and the s
elected fixed point is displayed in red.

• Introduce the remaining columns always using the object snap to snap to the fixed point, which is displayed
with a red circle in the template. When introducing a column whose fixed point is at its centre, the adjustment
will not have to be carried out.
Fig. 15.30
• Click on the bottom left hand corner fixed point to select it.
• Click on Accept.
• Click on the Full screen icon from the toolbar to obtain
a complete view of the floor.

mouse button.
Click on New column in the Columns, shear walls
and starts window. The New column window will
open. Click on Accept.

This process may be slow and tedious. However, there is
no need in carrying out a zoom on each column, a larger
zoom window can be used to view several columns, intro-

duce them snapping to their fixed points and then adjust
each one. In this example, the process has been described
in detail so it may be understood well.
Another option is to introduce all the columns by snapping
to their centre in the DXF template and then use the Change fixed point option, from the Columns, shear walls
and starts window. This option modifies the fixed point without displacing the column.
When this tool is selected, the Fixed point dialogue box will
appear. Here the fixed point of the column can be chosen
and then assigned to the columns which are to have their
fixed point at that position.
Fig. 15.36
• Bearing in mind that the columns are number from left
to right and bottom to top, click on the Assign button
and click on the columns P1, P3, P5, P8, P9 and P10,
which will be marked in red. Click on t
he right mouse
button and select Finish.
Fig. 15.35
• Click on Exit to close the Columns, shear walls and
starts window and to conclude the column introduction, click on the Beam Definition tab.
This way of introducing the columns may result to be more
comfortable, but remember that for the columns to be introduced correctly, the dimensions must be the same as they
are in the DXF template. If this is not the case, the fixed
point will not be in its correct position. Therefore if a DXF
template is being used where the dimensions of the columns differ from one another, these must be changed
each time a new column is introduced or alternatively, once
they have all been introduced, edited one by one.
15.2.2.6. Introduction of group 1: 1st floor
Having clicked on the Beam Definition tab, the program will
situate the user on the first floor.
Firstly, activate the visibility of the element references.
Now the start and end of the columns will be modified.
• Select Modify initial an
d final group from the Columns, shear wall and starts dialogue box.
• In the window that appears, deactivate the Initial
group box and for the Final group, select Roof.

introduced. If the menu disappears, it can always be activated by reselecting the Define beam option from the Beams/Walls menu.
• Beams can be introduced and adjusted to their respective positions in the DXF template in two different ways.
One way consists in snapping the axes, faces or edges
of the previously introduced columns and then adjusting the beam to the DXF template. The other way is by
snapping to the elements of the imported DXF te
mplate, and so the beam is adjusted when it is being introduced.

This adjustment, as well as displacing the beam so its side
face coincides with the template also establishes its fixed
side, which due to it being an edge beam at the façade of
the building is displaced 5 cm with respect to the face of
the column.

Having introduced this beam, its side has to adjusted to the façade drawn on the template. To do so,
activate the Nearest object snap from the Object
snap selection window.
It is normal for the width of the beam to vary as the analysis
of the structure proceeds, and if a side of the beam is to be
maintained at a fixed position after it has been introduced, it
must be adjusted (to a template line, column face, etc.)

• To introduce a beam using any of the methods described above, beam spans do not necessarily have to be
introduced from one column to the next column. Any
beam length can be introduced and the beam will remain joined to any column it overlaps.
Fig. 15.44
o
The symbol
which appears when the cursor is
brought close to a line of the DXF template indicates that if the user clicks on the left mouse button
at that point, the star
t of the beam will be at that
point. Introduce the initial and final points of the
beam by snapping to two points along the façade
line of the template, the first close to P1 and the second close to P5.
Now introduce the remaining beams:
• Beam P5 - P8 (from column P5 to column P8). The option Beams/Walls > Extend beam can be used to extend the end of beam P1-P5 or introduce a new beam
using Beams/Walls > Define beam and then adjust it
to the template line using the option Beams/Walls >
Adjust, as was done with beam P1-P5. Each of the
spans introduced must be adjusted; in this case only
the second as the first was adjusted previously.
• Beam P8-P10, flat 0.40m width. External side adjusted
to the template line. In this case, the two ends of the
frame are introduced as column P9 is aligned with columns P8 and P10.
Fig. 15.45
o
• Beam P4-P10, flat 0.30m width. External sides (right) of
both spans adjusted to the template line.
For the beam to span between column P1 and colu
mn P5, it must be extended using the Extend beam command found in Beams/Walls > Extend
beam. The beam may also be introduced without
the need of having to extend it later on. If the initial
and final points of the beam are snapped to points
• Beam P1-P2, flat 0.30m width. External sides (bottom)
of the three spans adjusted to the template line.
• Beam P2-P3, dropped 0.20 × 0.40 m. External sides
(bottom) of the three spans adjusted to the template line.
CYPE

• Beam P3-P4, flat 0.40 m width. External sides (bottom)
of the three spans adjusted to the template line.
• 0.25 m width flat beam closing off the bottom of the lift
opening. Similar to the previous case, it is introduced at
its approximate position, then adjusted.
• Beam P5-P7, flat 0.50 m width. Not to be adjusted, therefore the program maintains the longitudinal axis fixed
in case its width varies.
• 0.25 m width flat beam which closes off the right hand
side of the lift openin

introduced at its approximate position, then adjusted.
• Click on the Edit templates icon from the toolbar. In
the window that opens, deactivate the Visible box from
the top table.
The floor layout should be as follows:
Fig. 15.48
Fig. 15.47
It can be seen that beams introduced as flat beams do not
have depth. They will automatically adopt the depth of the
panel they hold.
The beam that has just been introduced contains a span,
P6-P7, which partly defines the stair opening, but its side
does not coincide exactly with the opening.
If two panels reach the same beam, the beam will adopt
the greatest depth of the two.
What must be done in the job (the user should correct and
reflect it in the drawing) is to infill the area between the side
of the beam up to the edge of the opening.
As there are important section variations in the same beam
alignment, it is convenient that the reinforcement be divided
at these section changes.
It does not ma
ke sense to move, in this case, the beam so
that its side coincides with the stair opening (as it would
have to be moved a large distance), and therefore, the axis
of the beam would not lie within the width of the columns.
• Click on Beams/Walls> Beam alignments > Divide
an alignment.
• Place the cursor over P2. A red dot and a scissor symbol will appear. Click on the column with the red mouse
button.
• Beam P2-P6, flat 0.30 m width. External side (right) adjusted to the template line which defines the stair opening.
• Repeat over P3.
• Beam P3-(P6-P7), flat 0.25m width. The beam spans
from P3 and ends perpendicular to beam (P6-P7). The
Orthogonal on/off option can be used from the toolbar or roughly introduce the second end of the beam
and then adjust to the template line.

The types of joist floor slabs available can be selected
by clicking on their respective image. By clicking on the

of joist slab is displayed. To be able to select some of
these types, the user must have acquired the corresponding modules. The selected default option is that of
a concrete joist floor slab to be used to introduced generic precast joist slabs. This corresponds to the first
image. Click on it if it is not already selected.
Follow these instructions to introduce the floor slabs:
• Click on Slabs > Panel manager. A floating menu will
appear. Initially and whilst no slabs are introduced,
nearly all the icons in this window will appear deactivated. This window contains most of the tools required to
manage slab introduction.
Fig. 15.50
• Click on the first icon from the floating menu
Panel manager dialogue box will appear.
• The properties of the slab that is going to be introduced
have to be defined. To do so, click on the
button which
lies below the joist images. A new dialogue box opens
where the corresponding data has to be introduced.

part of the screen, the layout of the joists is defined. For
this example, select the first option: Parallel to a beam
and accept the dialogue box.

CYPECAD - Practical examples
The remaining slabs can be copied from the one that has
just been introduced. This is recommended so that joists
from adjacent slabs have a continuous layout.
• To introduce an opening where a slab has been introduced, select Delete panel
from the floating menu,
then click on the slab to be
eliminated.
• To do so click on the Copy panel icon
from the
floating menu. Click on the slab that has just been introduced. A new window will open from which the data to
copy can be selected. Accept the window with the proposed selection.
15.2.2.6.3. Loads
There are two general methods to introduce loads. The first
is to introduce the loads manually using the options in the
Loads window (Loads >Loads). The second is available
for line and surface load introduction which consists of an
automatic introduction of loads on beams in the case of
line loads (Loads > Line loads on beams) and on slabs
in the case of surface loads (Loads > Surface loads on
slabs). The latter option is the quicker option and is useful
only if the loads are to be assigned to the entire element. In
the case of loads partially assigned to the element, the user
will have to judge whether to introduce the loads manually
or automatically and then edit them to obtain the real distribution.
Fig. 15.54
Now click o
n the openings to introduce the slabs displayed
in the following figure.
Follow this process to introduce the line loads:
• Click on Loads > Line loads on beams
• First introduce the dead loads. In the window that
opens, type in a load of 7.00 kN/m. Select Dead load
for the Loadcase.
Fig. 15.56
• Click on Add and the window will close so the load can
be introduced.
• Assign the load to all the perimeter beams.
Fig. 15.55
CYPE

• Complete the remaining loads.
• To introduce the live loads transmitted by the staircase,
select the Live load in the Loadcase compartment from
the Loads window.
• Introduce the two 6.00 kN/m line loads on the stair supports.
Fig. 15.60
Fig. 15.57
• Click on the right mouse button and select Finish from
the window that appears.
• Click on Loads >Loads.
• In the new window, select Line load, type in
12.00 kN/m, leave the Loadcase as Dead load and
select New. This will correspond to the self weight of
the staircase
on both supports:
Fig. 15.61
The floor introduction has been completed. The second
floor can now be defined:
• Click on the Up a group arrow in the toolbar.
Fig. 15.58
• It may occur that, if the described beam and slab introduction order has not been followed exactly, upon going
up to a different group, the program may ask for the
depth of the beam separating the stair and lift openings.
In this case, if the beam remains divided in two spans, it
has been defined as flat but does not have a slab on either side of it.
This is of no great importance. Introduce, in this case,
the same depth as has been defined for the slab. This
way, it remains a flat beam.

15.2.2.7. Introduction of group 2: 2nd and 3rd floors
15.2.2.7.1. Beams
Beams P1-P5-P8 and P8-P9-P10 are not to be adjusted to
the template line as they are in the group below, as they do
not coincide with the façades. They must be adjusted to
the column axes. To do so:
As th
is group is very similar to the previous group, it may
be copied and then edited to carry out the necessary
changes.
• Click on Groups > Copy
from another group. In
the window that opens,
place the mouse cursor
over the first group. The
text corresponding to the
Selected group at the
top of the screen will display 1. 1st floor. Click on
that floor or press Accept.
• Deactivate all the template object snaps (in the toolbar).
• Select Beams/Walls > Adjust followed by a click on
the longitudinal axis of the beam at the centre of its
span. This will adjust its axis with the axis of the columns on which it is supported.
If the cursor is not placed at the middle of the span, i.e.
the cursor is close to one of the beam ends, only that
end will be adjusted. However, the same can be done
at the other end.
• Repeat this process at each of the aforementioned
spans.
Fig. 15.62
• Activate the template by carrying out the opposite process to that explained earlier to deactivate it. Dea
ctivate the visibility of the loads by pressing Loads >
Shown.
It must be noted that adjustment to columns (be it to their
face or axis) can only be done if the template object snaps
have been previously deactivated.
The following beams will now be introduced. When the
connection of several beams does not occur at a column,
introduce beam segments shorter than their real length.
These beam spans can be adjusted to the DXF template
lines whilst they are being introduced or first introduced and
then adjusted later. Their ends are then extended and finally the unwanted ends can be cut off.
An example of what has been described can be seen in the
introduction of the beams parallel to the west and north façades. These beams define the two overhanging slabs of
this floor group. To introduce them, follow the instructions
described below:
Fig. 15.63
• Activate the Nearest object snap from the toolbar.

ct a flat beam width 0.25 m. To do so, click on the first
button of the floating menu
Current beam selection. If this window is not visible, activate it using the
Define beam option from the Beams/Walls menu.
• Now the final point of the beam fragment that is being
defined has to be defined. This can be done by approximating the cursor to the DXF template line where
the object snap symbol will appear, followed by a click
with the left mouse button at that moment. The beam
will have the following appearance:
• Select the Left adjustment by clicking on the
button
of the Define beam window. This button may differ depending on the current adjustment at the time:

• Introduce the first point of this beam by bringing the
cursor near to the DXF template line to be snapped to
until the snap symbol
appears on the DXF template
line as is displayed in the image.

• Introduce a beam segment parallel to the north façade,
following the same procedure as in the previous ex
ample. In this case use a 0.10 m wide non-structural beam
with a width of 0.10 m.
Fig. 15.64
• Once the object snap has appeared, click on the left
mouse button. If the mouse is then moved, the beginning of a beam can be seen anchored on its left side to
the point that has just been snapped to.

The roof layout is very similar to the previous group.
Introduce the geometry of the Lift machinery roof, which is
shown in the diagram below. There are no line loads.
• Copy the group below. The line loads must be modified.
• The external line load values are changed from 7.00 kN/m
to 4.00 kN/m corresponding to the roof wall. This can be
done using the option Loads > Loads > Edit.
• The roof wall has a brief interruption when it reaches
the wall of the lift machinery room. The loads must be
moved. Do so using the option: Loads > Loads >
Move.

N/m.
15.2.2.10. Introduction of group 0: Foundations
15.2.2.10.1. Pad footings
The loads transmitted by the staircase can be reduced as
the stair only reaches the floor. The start loads of the stair
can be deleted.
The foundations of the building will consist of pad footings.
• Click on the Go to group icon in the toolbar and in the
window that opens select Foundations. The first elements to introduce will be the pad footings followed by
the strap and tie beams.
The loads around the perimeter of the lift opening are increased to 8.00 kN/m. These correspond to the machinery
slab where it is supported and the walls that support the
slab. This slab must be designed in a separate file. The
load distribution should look as follows:
• Select Foundation > Foundation elements. The following floating window will appear:

Nothing has to be selected. The scroll menus display

beams parting from the smallest that exist in the table.
Now that all the data has been introduced, the structure
can be analysed. If the data has not been completely introduced as has been instructed up to this point, this example
is available at \CYPE Ingenieros\Examples\CYPECAD.
• Therefore, click on Accept.
• Introduce the first beam between P1 and P5. It can be
seen that the balancing symbol only appears at the bottom end of the beam, which is the only position where
the balancing action is required. Now introduce the remaining beams as shown.
• Click on Analyse > Analyse the job (except foundation).
The reason why the foundation should not be analysed,
for the time being, is due to the reason that, usually, columns, beams, etc require section modifications after
the first analysis, and therefore a new analy
sis of the
structure must be launched to account for any load
changes.
The foundation of the structure can be designed, as will
be seen later on, having completed the rest of the structure.
Once the analysis has concluded, a report appears on
screen informing the user of any errors that have arisen.

15.2.4.1.1. Displacements (only with horizontal loads)
Even though horizontal loads have not been used in this
job, it is necessary for the analysis to be carried out considering second order effects (the coefficient that multiplies
the displacements will be left the assigned value of 1).
When the analysis has ended, it should be checked that
the global stability coefficient is greater than 1.20. If so, the

stiffness of the structure must be increased in that direction, as it is
easily deformed and has little stability in that direction. If the value is less than 1.1, its effect is negligible.
It must be taken into account that the forces provided by
the program belong to simple loadcases and, therefore,
they do not have an applied safety factor and are independent for dead loads, live loads, etc.
15.2.4.1.2. Force check
15.2.4.1.3. Section check
The user may consult axial forces, moments, shear and torsion forces by loadcase at any column elevation, analytically and graphically.

The worst case forces can also be consulted (loadcase
combinations which result in having to provide maximum
reinforcement) for any span.
Click on Envelopes > Forces in columns and shear
walls. Click on a column, for example P6.
Fig. 15.90
In the bottom left hand corner of the window, the Plan
view of the columns can be seen. Here, the columns
sharing the same
reinforcement (i.e. which belong to
the same column group) are highlighted with a circle;
one of them in a bold circle. In this case, P1 is in the
bold circle. This means P1 is the master column of the
group, hence any modifications carried out on P1 will
also be carried out on the other columns of the.
Fig. 15.89
It is recommended that, if not all, at least some of the columns of the structure are checked.
The axial force at the start of the column provided by the
program must be approximately equal to that calculated by
hand. The variance is due to the difference in the estimated
tributary area due to the hiperstaticity of the structure in general and especially of the slabs.
CYPE
CYPECAD - Practical examples
If horizontal loads are present, it is recommended the
section of the columns be increased when reinforcement bars with a diameter greater than 16mm appear.
This way, it will avoid, after the second analysis, 25mm
reinforcement bars being used.

A more detailed report of the checks carried out on the
column can be found in the Summary of code
checks section on the bottom right hand corner of the
Column edition window. If there are any errors, the column section has to be redesigned.
Upon modifying the column section in this window, the
reinforcement redesign of the columns will be carried
out using the simple loadcase combinations belonging
to the last analysis.
If the section modifications are important, or if they are
of little importance but horizontal wind and/or seismic
loading is prese
nt, the structure must be reanalysed
with the new sections as their inertia will have varied.

Bear in mind that these envelopes have an applied safety factor and, as was said previously in the case of
forces in columns, the tributary area considered by the
user when carrying out manual calculations is only an
approximation to what occurs in reality, due to the hiperstaticity of the slab. The user must also be aware
that the simply supported moment W L2 /8 is for line
loads but what the joists really transmit to the beam is a
series of point loads.

First option:
• Click on Foundation > Foundation elements > Edit.
• Click on the footing below P6. The following window will
open.
Fig. 15.121
A more uniform result is obtained by using this matching
method. In some occasions, the negative moment of a joist
that coincides with a column is substantially different to the
other
joists of the same panel. By matching the steel areas,
the negative moment difference is shared amongst the
joists adjacent to the joist that coincides with the column (it
is logical for the joist to behave like this in reality), and so
the difference with the remaining beams of the slab is not
so large. This, occasionally, implies that all the top reinforcement of a slab must be matched with the same reinforcement or that, at least, the difference between the top
reinforcement of the joists belonging to the same slab will
be smaller.

First and foremost is to identify how many groups (levels)
there are in the building. This example will contain 6:
ground floor, first, second and third floor, roof and lift machinery roof. As floors 2 and 3 are the same, geometrically
speaking, and their loading is also, these two floors can be
grouped, resulting in a building of 5 groups and 6 floors.
load to the slab equivalent to the increase in dead loading
corresponding to the infill. This is the case in this example,
and so a load will be introduced to represent the infill
.
If the elevation difference or surface area is large, an elevation change should be assigned to the floor slab using the
option Groups > Sloped floor slabs/El. Changes. This
way, the program creates a floor slab with two elevations
and if these are separated by a flat beam, the beam will
change to acquire the depth of the slab plus the elevation
change between the two slabs. If the elevation difference is
greater and the user does not wish for there to be a
connection between the two parts, an intermediate group
will have to be created between the current and the following floor. In this case, the height of the intermediate floor
will be the elevation change between the two floor areas.
NB: It must be taken into account that if there is going to be a
start or end of a structural element (column, wall, stair nucleus or
sloped beam), it cannot occur at a grouped floor; it must be defined as an individual floor.
15.3.1.1. Floor heights
When there is an elevation change in a floor, a
s occurs in
this example where there is an area on the ground floor
42 cm higher than the rest of the floor, depending on the
elevation difference and surface area of the floor slab, there
are different ways as to how it can be defined in the program.
15.3.1.2. Loads
15.3.1.2.1. Permanent loads
First the permanent loads acting in the example will be analysed so to then introduce them when defining the project in
the program. Note that the slab loads, once the slabs to be
introduced have been defined, will be applied internally by
the program. Therefore, the user does not have to define
them when introducing the dead loads to be applied.
If the elevation difference is small (<0.65 m) or the surface
of the higher area is not too large, the user may opt to infill
the area, without altering the height of the floor slab. In this
case, the only thing that must be done is apply a surface

15.3.2.2.3. IFC Assistant: Floor loads
Here, the live and dead loads will be introduced. The Basement does not have any loading as the structure’s foundation elements will consist of pad footings.
The ground floor is to have a live load of 5 kN/m2 and a
dead load of 2.1 kN/m2 (partitions + screed). The residential floors are to have a live load of 2 kN/m2 and a dead
load of 2.1 kN/m2. Finally, the roof and lift machinery roof
are to have an applied live load of 1.2 kN/m2 (live load +
snow load) and a dead load of 1.5 kN/m2 (roof screed).

15.3.2.3.2.5. IFC Assistant: Floor slabs
Now that the column materials to be imported have been selected, the floor slab materials are to be selected as well as
their perimeter beams and the beams defining the openings.
The assistant displays a similar list to that of the columns,
with the floors/floor slabs defined in the IFC
file. Upon
clicking on one of these, it is displayed in red in the 3Dview.
Those that are not to be imported are deactivated in the
Import column (Floor: road, Floor: pavement, Floor: Generic 100, Floor: Generic 200 mm).
Fig. 15.159
15.3.2.2.4. IFC Assistant: Columns
Having defined the floor loads, the columns are now to be
defined. The assistant displays the different materials with
which the columns have been defined; in this case only
one. The columns made of the same material as that displayed in the list are drawn in red.

Once these have been deactivated, click on Floor: Waffle
slab. To the right, in External Outlines, select the flat beam
(first on the left), assign a thickness of 30 cm to it and for
Openings select the limit beam (first on the right) with 0 cm
thickness.
All the materials corresponding to partitions will be deactivated in the Import column.
Repeat the process for Floor: Generic 300.
15.3.2.2.6. IFC Assist
ant: Partition loads
Now that the floor slabs have been defined, the partitions
to be imported are selected. These are assigned a material
which has an associated surface load. The program will
then calculate the corresponding line load to apply on the
floor slab depending on the height of the partition.
In a similar way as with slabs, upon clicking on a partition
from the list, it will appear marked in red. To assign the material, click on the Not defined button to select the type. In
the example a generic material has been used with a load
of 2.86 kN/m2.

In the Loads section of the dialogue box, activate the With
wind loading box. The Gene

new window that opens, introduce the tributary widths of
the building. Click on the By floor button and introduce a Y
value of 23 m and an X value of 17m for groups 1 to 5 and
Y = 4 m and X = 7 m for group 6. Change shape factor x
to 1 and shape factor y to 1.35. Leave the gust factor and
wind action values as they appear in the program.
15.3.3.1.1.Code and materials
Once a name has been given to the project, the General
data window appears. The codes to use, materials and
loads to be applied in the job are to be specified in this
dialogue box.
For this example the Eurocodes will be used. By clicking on
the Codes button, a new dialogue box will appear where
the codes to be used for each material can be selected:

15.3.3.1.3. Earthquake loads
The seismic loa
ding can be activated by selecting the With
seismic loading box in the General data dialogue box.
From the window that opens, select the Modal spectral
analysis option on the left. The corresponding screen will
appear on the right where the data can be defined.
For this example, an acceleration due to gravity of 0.10 g
will be used. The ductility shall be left at 2.50 and the part
of snow and live loads to consider will be left at 0.5.
As for the number of modes, the number to be selected
must be such that the whole mass of the structure is displaced. 3 modes of vibration can be considered for each independent zone, i.e. for this example 18 vibration modes
should be considered (6 floors with 3 vibration modes each).
Bear in mind that the higher the number of modes is considered, the longer the analysis will take as this number affects the number of combinations the program undertakes
when designing the reinforcement. Therefore it is preferable,
for the initial analysis whereby what is
sought is to obtain a
rough idea as to the eventual dimensions of the elements,
that the 6 default modes be left. Once the first analysis has
concluded, the report containing the participation coefficients may be consulted and if the percentage of the displaced mass is greater than 95%, then the number of modes
considered is adequate, otherwise it must be increased.

15.3.3.1.4. Fire resistance
To carry out the fire resistance checks and the structural

Columns may be introduced manually or via automatic introduction. In this second example, the structure has been
introduced automatically. Please refer to the first example
for a more detailed explanation as to how to introduce the
columns manually.
If the job has been imported using an IFC file, any floors
that are to be grouped should be specified. As was mentioned in section 15.3.1., floors 2 and 3 are to be defined as a
single group. To do so, go to option Introduction >
Groups > Join groups in the Column definition tab. In
the window that opens, a diagram of the floors is displayed
with a red bracket indicating which floors are to be joined.
Select floors 2 and 3.
After importing the job using one of the two automatic assistants, the column
s must be reorganised so that their references follow an order which allows for an easy consultation. This is especially important for large jobs where having
to locate a column without these following a specific order
can be very complicated.
To edit the references, click on Introduction > Columns,
shear walls and column starts > Modify reference.
Click on the bottom left hand column; this will be the first reference. In the dialogue box that appears, provide a reference for this column and select the Number consecutively box. Then, one by one, click on the columns in order,
from left to right and bottom to top.

If any beams have been introduced in the Basement, these
too must be deleted.
• Normabloc wall
• Reinforced concrete block wall
• Masonry walls
