The “Timber joist floor slabs” module has been implemented in the 2017.a version, with which CYPECAD analyses and designs timber joist floor slabs.
A summarised description of this module can be found in the “Timber joist floor slabs” section of the new features of CYPECAD.
More information on the introduction, analysis and design of the timber joist floor slabs can be found on the “Timber joist floor slabs” webpage.
As of previous versions, users have been able to introduce “Generic” structural timber elements in integrated 3D structures in CYPECAD and CYPE 3D using the “Timber sections” module.
Further features have been added to the “Timber sections” module with the 2017.a version. Now, users can introduce beam-type timber elements in CYPECAD and CYPE 3D. By introducing the timber beams as that type of structural element instead of generic timber beams, allows specific beam checks to be carried out, and use the “Advanced beam editor” to edit and design these elements.
A summarised description of this new feature of the “Timber sections” module can be found in the “Timber beams” section of the new features of CYPECAD.

The “Timber joist floor slabs” module has been implemented in the 2017.a version, with which CYPECAD analyses and designs timber joist floor slabs.
The codes implemented for the design and check of the timber joist floor slabs and beams are:
To adapt the program to the current market, timber sections have been created, distinguishing between sawn timber and laminated timber, and including the DUO/TRIO series, which are currently very much in use.
The sections that make up the timber joists are designed for simple bending, because due to the rigid diaphragm hypothesis, axial forces and forces in the plane of the floor slab are not considered.
The deflection checks for timber joists are obtained considering the deflection limits for the joist defined by users and the active deflection and long-term deflection.
CYPECAD also carries out a fire resistance check for timber beams using the “Fire resistance check” module.
For CYPECAD to be able to analyse and design joist floor slabs, the user licence must include, as well as CYPECAD, the “Timber joist floor slabs” and “Joist floor slabs (generic concrete beams)” modules. If, users also wish to check the fire resistance of these elements, they must also hold the “Fire resistance check” module permits.
More information on the introduction, analysis and design of timber joist floor slabs in CYPECAD can be found on the “Timber joist floor slabs” webpage.
Users can, as of previous versions, introduce generic-type structural timber elements in the integrated structures of CYPECAD and CYPE 3D using the “Timber sections” module.
In the 2017.a version, the “Timber sections” module has further features and allows users to introduce beam-type structural timber elements in CYPECAD and CYPE 3D. By introducing the timber beams as that type of structural element instead of generic timber beams, allows specific beam checks to be carried out, and use the “Advanced beam editor” to edit and design these elements.

CYPECAD and CYPE 3D also carry out a fire resistance check for timber beams using the “Fire resistance check” module.
For CYPECAD and CYPE 3D to be able to analyse and design timber beams and generic timber bars, the user licence must include, as well as the permits corresponding to CYPECAD and/or CYPE 3D, the “Timber beams” module. If, users also wish to check the fire resistance of these elements, they must also hold the “Fire resistance check” module permits.
More information on the introduction, analysis and design of timber beams in CYPECAD and CYPE 3D can be found on the “Timber sections” webpage.
Ultimate limit state and serviceability limit state check reports for steel joists have been implemented in the program. The option: Check (steel and timber) has been included in the “Joists” menu in the “Results” tab, which allows users to obtain the ultimate limit state and serviceability limit state checks of each joist. This option is also used to obtain the check reports of timber joists, also implemented in the 2017.a version.
The 2017.a version of CYPECAD includes a fire resistance check for steel joists. The data definition for the fire resistance check of steel joists in CYPECAD is the same as for steel beams in the “Fire resistance check” dialogue in the “General data” option (Project > General data > Loads > Fire resistance check). As occurs with other structural elements of CYPEAD, the required resistance and cladding (if present) for each type of structural element is defined for each floor group.
Different data can be defined in any zone of a floor group using the options in the Fire resistance floating window (Groups > Fire resistance from the Beam Definition or Results tab).
CYPECAD will carry out each resistance check at room temperature (persistent or transitory situation) and in the case of a fire, in accordance with the specifications of the code.
The joists of adjacent panel can now be assigned as being continuous, for steel and timber joists. This way, the program will design each continuous joist of both panels as if it were a single element.
In previous versions, when steel joists (and now timber joists) were introduced, the panel were designed independently, and the joists were assumed to be simply supported, except in the case of overhangs, where they were automatically fixed in order to maintain equilibrium. In this case, if the joists have a design error, the program will indicate that it is not possible to design the joist as a continuous element.
As of the 2017.a version, the program allows users to assign continuity to joists of the panels selected by users. In the “Type of span to calculate the deflection” (Slabs > “Joist continuity”) dialogue box, CYPECAD allows users to select two types of continuity for steel and timber joists:
It is important to note that in the analysis of the panels with continuity, due to differences in stiffness, the results will not be the same if the analysis is carried out with the first section of the series or if the analysis begins with an intermediate section. Therefore, as occurs with the design of other steel and timber elements, an option has been added for steel and timber joists in the “Design options” dialogue box (which appears once the “Analyse” option has been selected when there are steel or timber elements present).
In the seismic analysis of the structure, CYPECAD can design structural beams as primary or secondary beams, depending on their role in the earthquake-resistant structure (Beam Definition > Beams/Walls > Secondary beams). Secondary beams are not considered as being part of the structural system to resist seismic loads hence, these elements do not need to be designed specifically for that.
The stiffness of the secondary beams, for seismic loadcases, is reduced depending on the value defined in the “Inertia reduction factors” dialogue box (“Project” > “General options”). The mass of the secondary beams is taken into account.
As for the capacity checks, users can indicate how the secondary beams are to be considered depending on their judgement. The following options can be activated in the “Secondary beams against seismic action” dialogue box (“Project” > “General data” > “Design options for steel bars” > “Beam options” “Design/Code check”):
In the 2017.a version of CYPECAD, users can introduce a partial fixity coefficient at the end of a concrete beam. To do so, the option: “Fixity at beam end” (Beam Definition tab > “Beams/Walls”) has been implemented, which opens a dialogue box in which users can indicate that the beam end is:
When this option is selected, symbols are drawn, in a different colours and shapes, at the ends of the beams to indicate which option has been applied.
In previous versions, beam ends could be pinned or fixed using the “Pin/Disconnect” option which is also used to disconnect columns from wall-support type beams. Now this option is only used to disconnect columns and is now called “Disconnect/Connect”
In the 2017.a version, users can select the frames of each group to be represented in the “Frames drawing”. To do so, an option: “Selection in groups” has been implemented in the “Frames drawing” configuration dialogue (File > Drawings > Add or edit the “Frames drawing”). Upon selecting this option, a button is displayed indicating the number of selected frames that are going to be represented in the drawing (which by default , are all the frames of the project). By pressing this button, a dialogue box appears where users can select which frames from which floors are to be shown on the drawings.
With the 2017.a version, shaded force diagrams of beams and joists can be displayed (with a different colour depending on the type of force). To do so, a new option “Draw the diagrams with infill” has been included in the “Forces in beams” and “Forces in joist” dialogue boxes (Results > Envelopes > “Forces in beams” or “Forces in joist”)
Users can, as of previous versions, introduce generic-type structural timber elements in the integrated 3D structures of CYPECAD and in CYPE 3D using the “Timber sections” module.
In the 2017.a version, further features are added to the “Timber sections” module and now users can introduce beam-type structural timber elements in CYPECAD and in CYPE 3D. By introducing the timber beams as that type of structural element instead of generic timber beams, allows specific beam checks to be carried out, and use the “Advanced beam editor” to edit and design these elements.
More information on the new features of the “Timber sections” module, applicable to CYPECAD and CYPE 3D, can be found in the Timber beams section of the new features of CYPECAD on this webpage.
Once CYPE 3D has analysed a shell, “Integration strips” are generated in the two-dimensional element to process the nodal solutions provided by the finite element method and calculate the resultant force at specific sections of interest for the analysis.
As of the 2017.a version, the resultant can be calculated by applying one of the following methods:
As of the 2017.a version, StruBIM Analysis 3D and StruBIM Design are no longer BETA versions and are completely operational.
To design and check floor slabs and walls, StruBIM Design processes the results from their analysis based on the finite element method. This analysis provides solutions at specific points of the 2D structure, depending on the established discretisation. Based on these solutions, the design values required for the design and reinforcement are obtained by generating integration strips in the two-dimensional element and the calculation of the resultant in the corresponding design section.
As of the 2017.a version, StruBIM Design offers users the possibility to calculate this resultant by applying the “Internal forces integration method” or “Nodal forces integration method”.
The first premise is to have the internal and/or nodal forces in the 2D elements considered, to be able to apply one method or another. Depending on the origin of the analytical model which is being worked on (xml, sbar, etc.), the available design data may vary. Obviously, when only one of the types of data is available, only the corresponding method can be applied. If both the internal forces and nodal forces are available, it is the user’s choice which method is most adequate. The following observations on the methods can be used to guide users as to which method they should apply:
The 2017.a version of StruBIM Design includes the definition and check of concrete and steel composite columns. These are checked in accordance with the ANSI/AISC 360-10 code.
The types of composite columns the 2017.a version of StruBIM Design can check are:
As well as the existing design properties of previous versions, the 2017.a version implements options to edit the following properties:
As of the 2017.a version, users can select between two types of reinforcement for wall spans: “Reinforcement by faces” (this is the type in previous versions) and “Confinement reinforcement” (new type). This new type allows for typical reinforcement to be defined at wall ends.
A shear wall can be composed of several spans with the same or different thickness. Each span of the wall can be assigned different reinforcement strips, for their composition or type.
The program designs and checks the reinforcement depending on the selected type.
As of the 2017.a version, StruBIM Design carries out a punching shear check on floor slabs supported by columns. The program automatically generates the critical section for each column that transmits forces to the floor slab and allows for it to be edited. StruBIM Design verifies, for the critical perimeter, if the resistance against tangential stress is exceeded in floor slabs without shear reinforcement, which resist bending in both directions. Additionally, users can now introduce shear reinforcement in floor slabs and check critical sections with reinforcement.
The program allows users to introduce shear reinforcement as stirrups or shear studs and verifies the resistance at the perimeters at either side of the reinforcement. Furthermore, StruBIM Design checks the geometric layout and reinforcement in accordance with the design code.
The layout of the column can be modified (centre, edge or corner), as can the effective depth of the floor slab, the maximum and minimum width of the support, and the critical perimeter of the support and reinforcement (taking into account openings and edges, indicating the effective segments against punching shear). It is also possible to modify the reinforcement data of stirrups and shear studs.
The forces at the top and bottom of each support can be consulted. The difference between these forces corresponds to the punching shear forces transmitted to the floor slab at that floor.
Punching shear of columns close to each other, with their internal and external perimeters together, can be checked and their perimeters edited.
The 2017.a version includes the design and check of steel beams in accordance with the requirements of the ANSI/AISC 360-10 code.
The types that have been implemented are:
Air discharge, return and extraction grilles can be defined. The program allows users to define libraries, where each grille is defined with a reference, dimensions and range of allowable flows, amongst other properties.
The grilles are incorporated in the floor plan and each one can be assigned an air flow corresponding to the design results. The program will emit a warning if the assigned flow is excessive or insufficient.
Implemented in the 2017.a version is the design of air ducts using air flow drag from the grilles to the initial span of the network.
The total area of rectangular ducts, total length of circular ducts by diameters, as well as the number of grilles of each type have been incorporated in the quantities report.
Users can now define chillers and heat pumps. As well as their graphical representation on drawings, their main technical properties can be defined (air or water condensation, 2 or 4 tubes, operation temperature).
Similarly, the program provides the association of the power required by the water meters of the systems (air conditioners, fan coil groups) to obtain the total sum of the power that is required.
Up to the 2016.n version of Arquimedes, the unit concepts could be classified depending on their type or nature: “Material”, “Labour”, “Machinery” and “Unclassified”.
As of the 2017.a version, the “Material”, “Labour”, “Machinery” and “Unclassified” unit concepts can be classified in other classes or subclasses. This way unit prices can be identified to be classified by different Nature and Class levels. For example, materials or machinery can be classified as they are defined in the table shown below:
Material | ||
Concrete | ||
Blinding concrete | ||
C25 concrete | ||
C15 concrete | ||
... | ||
Aggregates | ||
Gravel | ||
Clay | ||
Lightweight aggregates | ||
... | ||
Machinery | ||
Machinery for land movement | ||
Backhoe with tyres | ||
Backhoe on chains | ||
... | ||
Compacting material | ||
Plate compactor | ||
Ram compactor | ||
... |
The option to be able to carry out this classification is located in the menu: Show > Concept classification > Classification by nature.
The Unit concept classification tables allow for all the unit concepts to be classified using unified indices. Currently, the unit concept price indices used in Mexico have been introduced. In upcoming program versions, unit concept price indices of other countries will be introduced and the polynomial formula for those countries will be obtained.
The Unit concept classification table provides the Price adjustment indices to be able to create the polynomial formula to check or adjust prices in those countries where polynomial formulas are not pre-established by the code.
The option to create Unit concept classification tables is located in Show > Concept classification > Unit concept classification tables.
