Description of problems to resolve The deformation compatibility is established at all nodes, taking into account 6 degrees of freedom and the hypothesis that each floor of the structure cannot be deformed, preventing any relative displacements between nodes of the floor (rigid diaphragm). Therefore, each floor will only be able to rotate and suffer displacements as a whole (3 degrees of freedom). CYPECAD has been conceived to carry out the force analysis and design of reinforced concrete and steel structures supporting joist floor slabs (generic, reinforced, prestressed, in-situ, steel and open web joists), hollow core plate slabs, composite slabs, waffle slabs and f

The supports can consist of reinforced concrete or steel columns, reinforced concrete shear walls, reinforced concrete walls, with or without lateral pressures or masonry walls (generic or concrete block walls). The foundations can be composed of footings or pile caps, or alternatively by use of mat foundations. The foundations can be designed individually with respect to the rest of the structure by simply introducing the column starts. Reinforced concrete stairs, supported by the floor slabs can be also be introduced. The rigid diaphragm state for each independent zone is maintained even if only beams and no floor slabs have been introduced in the floor, , except for the case of exempt beams which the user disconnects from the rigid diaphragm and walls that are not in contact with floor slabs (as of the 2012.a ve

When independent zones exist on a single floor, each one will be taken as a different section when regarding the deformations of the zone and the influence of the other zone will not be taken into account. Therefore, each floor will behave as independent non-deformable planes. A column which is not connected to an element is considered as an independent zone. Using the program, the technical drawings of the structure can be obtained which include the dimensions and reinforcement of beams, columns, shear walls and walls via plotter, printer and/or DXF/DWG or PDF files, as well as the analysis reports and results. If the Metal 3D license has been acquired, Integrated 3D structures can be introduced using steel, timber and aluminium bars.

This may even cause negative reactions to arise, which represent the weight of the column or part of its weight ‘hanging’ at the wall support. • Beams These are defined on the floor layout by fixing nodes at intersections with the surfaces of support elements (columns, shear walls or walls), as well as at intersection points with floor slab elements and beams. This way nodes are created along the axis and at the ends, at the ends of overhanging beams, free ends or at contact points with other floor slab elements. They possess, by default, 3 degrees of freedom, maintaining the rigid diaphragm hypothesis between all the elements located on the floor. For example, a continuous beam supported by various columns will conserve the rigid diaphragm theory even though no floor slabs are present. Exempt beams can b

Especially in the case of a pinned connection with displacement, when a beam is connected to the end of a wall support a fixed effect is obtained due to the beam being taken as an extension of the crown beam of the wall support. This can be observed in the force envelopes whereby negative moments are present at the end. In reality, it must be verified whether or not these conditions will actually be met on site as they must be complied with when it is executed. Reinforced concrete, steel and composite beams are available. Beams are discretised as bars whose axis coincides with the mid plane passing through the vertical web, and at the height of its centre of gravity. If the beam is not a straight extension of the wall support but deviated from its axis, a hinged effect is produced. Wall support simulation.

he static moment (=wl2/16 for a uniform load) is reasonable for positive and negative moments. It is recommended the user consult the Options. 1.4.3. Torsional stiffness coefficients An option exists whereby a torsional stiffness reduction coefficient can be defined (x). This option is not applicable to steel sections. When the dimension of the element is less than or equal to the value defined for short bars, the value defined within the options will be taken. The gross section (G.S.) will be considered for torsion GJ, and for when it is required to achieve equilibrium of the structure. The bending moment envelopes will be displaced so that these minimum moments are met, followed by the negative moment redistribution that is to be applied.

The overlap at each floor level, in the case of disconnected columns, can be ignored and hence provide reinforcement without overlaps until the next floor or overlapping at all floors, even though no beams reach the columns at that floor, as long as the reinforcement is identical. If the applied minimum moment is less than the design moment, the greatest of the two is taken. • Cutting of starter bars at the last span (top of column). This option cuts the starter bars at the top of the column’s last span. Only drawings and reinforcement take-off values are affected by this option.

So, additional loadcases of a different nature may be created (dead load, live load, wind, earthquake and snow) and combine them with those that have been previously created automatically and amongst themselves (this is not compatible with wind and seismic loads). Additional loadcases associated to Lateral soil pressures and Accidental loads can also be defined. Dead loads These are estimated as being uniformly distributed on the floor. These are elements such as flooring and partitions (even though this last element could be considered as being a variable load if its position or presence varies with time).

Wind loads The program automatically generates the horizontal loads to be applied at each floor, in accordance with the selected code, in two orthogonal directions X, Y, or in a single direction, and for the two cases (+X, -X, +Y, -Y). A load coefficient can be defined for each wind direction and case. If a building is isolated the pressure will act on the windward face of the building and the suction on the leeward side. It is usually estimated that the pressure is 2/3 = 0.66 and the suction 1/3 = 0.33 of the total pressure. Therefore for an isolated building, the load coefficient is 1 (2/3 + 1/3 = 1) for each direction. If the building is protected on its left side because of an adjacent building in the X direction, the wind coefficients may be modified to reflect the situation. In this case +X = 0.33 as there is only suction in the leeward direction and –X = 0.66 as there

These curves display the total pressure as a function of the building’s height. These values are interpolated for intermediate heights, which is necessary to calculate the pressure at the height of each floor of the building. The Shape factor is a coefficient which is applied to the building to correct the wind load depending on the shape of the building. This may be due to the shape of its floors being rectangular, circular, etc. and because of its slenderness. Fig. 1.12 Once the tributary width of one floor is known, and the heights to the floor above and the floor below, if the half sum of these two heights is multiplied by the tributary width, the surface exposed to wind on that floor is obtained. If this is then multiplied by the total pressure calculated at that height and by the load coefficient, the wind load for that floor and in that direction will be obtained. A Gust factor can also be defined. This is a coefficient which amplifies the wind load so to take into account

the geographical position of the building in exposed locations such as valleys, hill-sides etc. These situations produce greater wind speeds and so should be taken into account. The total wind load applied to each floor is obtained by multiplying the pressure at its height by the exposed surface, shape and gust factors. The application point of the load at each floor is at the geometric centre of the floor, determined by the perimeter of the floor. The value of the wind load applied at each floor can be consulted and displayed in a report. If there are guardrails (or a solid perimeter wall) on the roof, it can be taken into account by proportionally modifying the band width b and using b’. For each defined code, the pressure is calculated automatically, once the initial data has been introduced which can be consulted within the code to be used.

Seismic loads can be introduced as a system of static forces equivalent to the dynamic loads, generating horizontal loads in two orthogonal directions X and Y, applied at each floor level, at their centre of gravity. As a general method, the seismic loads can be applied by floor coefficients. The second order effects may be considered if the user wishes for them to be so. Within the integrated 3D structures, if the static earthquake loadcase is activated as loads on nodes and bars, it cannot be combined with seismic loads by coefficients or with dynamic seismic loading. Similarly, if a static analysis using floor coefficients is to be carried out in CYPECAD, it cannot be carried out for the integrated 3D structures, hence, the structure cannot be analysed.

Therefore, this vector represents a direction or deformation mode, and not specific values of the solutions. Based on the vibration modes, the program obtains the participation coefficient for each direction (τi) in the following way: Finally, a displacement and force distribution over the whole structure is obtained for each vibration mode and for each dynamic loadcase, with which the modal spectral analysis is concluded.

Base shear When the base shear due to dynamic seismic loading is less than 80% of the static base shear, the proportion will be increased so not to be smaller than it. The second order effects can be considered, if the user wishes for them to be so, by activating the option, as the program does not consider them automatically. ∆ Consideration of 2nd order effects (P∆) Upon carrying out the analysis, the user may consult, for each mode, the period, the participation coefficient in each design direction X, Y and what is referred to as the seismic coefficient, which is the displacement spectrum obtained as Sd: The user may optionally choose to consider, when

This causes it to be an unpractical solution using the analysis methods available. Therefore a simplified method must be established consisting of supposing a reduction in the stiffness of the sections, which implies an increase in the displacements, as they are inversely proportional. The program requires the increase or ‘multiplication factor of the displacements’ to take this stiffness reduction into account.

In Brazil, it is common to consider a reduction coefficient of the longitudinal elasticity modulus of 0.09 and assume a reduction coefficient of the fissured inertia with respect to the gross inertia of 0.70. Therefore, the stiffness is reduced by these factors: For this case, it is to be calculated and always taken into account if the value is exceeded, which results in always having to consider the calculation and amplify the fo

Reduced stiffness = 0.90 · 0.70 · Gross stiffness = =0.63 · Gross stiffness Regarding the displacement multiplication coefficient, it is indicated that given that the horizontal loads are temporary and act during a short period, a reduction of approximately 70% of the inertia can be considered, and as the elasticity modulus is smaller (15100 / 19000 = 0.8), in other words, a displacement amplification coefficient of 1 / (0.7 · 0.8) = 1.78, which according to the global stability coefficient, does not exceed 1.35 would be a reasonable value. Due to displacements being the inverse of the stiffness, the multiplying factor of the displacements will be 1 / 0.63= 1.59. This value will be introduced into the program. As a general rule, if γz > 1.20, the structure’s stiffness should be increased in that direction, as the structure can deform easily and has little stability in that direction. If γz < 1.1, its effect is small and practically negligible. In the

It may be appreciated that the model code criteria would be recommendable and easy to remember for all its application cases: In the 1990 CEB-FIP model code, a moment amplification method is applied which recommends, unless a more precise analysis is undertaken, the stiffnesses be reduced to 50% or similarly, apply a displacement amplification coefficient equal to 1 / 0.50 =2.00. For this assumption, it may be considered that if γz > 1.50, the structure’s stiffness in that direction must be increased, as the structure can deform easily and has little stability in that direction. 2nd order effects do not have to be considered if γz < 1.1, however it is recommended they always be activated.

Type of floor slab The existence or non-existence of continuity between joists of adjacent panels can be achieved (except in the case of steel and open web joists, which are always simply supported). By copying panels, continuity is obtained from one to the next. By varying the insertion point, so joists in adjacent panels are not aligned, the continuity is eliminated. This is achieved as long as the distance between the ends of the joists of adjacent panels is greater than the short bar length (default value of 0.20m, which can be varied using the option Reduction coefficient of flexural stiffness of joist floor slab. The same continuity effect is produced if a beam is located at the end of a joist and works as an extension of the joist, where the separation of their axes is less than the short bar length. The floor slab is defined by giving it a name and introducing a series of data: 1.9.9.3

This check is not carried out when data has not been defined for deflection, environment or shear analysis. The superposition of the two stages leads to a load state which produces greater positive moments than negative moments, in the majority of cases. Within the Panel manager option, the environment can be selected, as well as the fixity coefficient at edges and minimum moments for each type of span: end, intermediate, isolated or overhanging. In the current version of the program, the analysis is not carried out in two stages. If the floor is constructed without shoring (case B), reasonably approximate results that concur with what is expected are obtained. This is done by modifying the fixity coefficients in the continuous panels.
