CYPECAD carries out the design, analysis, and sizing of structures for building and civil works, which are subject to vertical and horizontal forces, as well as fire exposure.It analyses and designs:
General data and options
With CYPECAD, users have complete control over the general data that will determine the analysis and modelling of the structure they wish to enter:Selection of standards to apply:
When introducing structures in CYPECAD, several of the methods outlined below can be combined accordingly. The choice of procedure will depend on users’ preferences, the way they receive project data, or the element or information being introduced.
This versatility adds speed, reliability, and efficiency to the process of introducing a structure.
The structural supports that CYPECAD analyses and designs are:Columns
These walls can be designed with or without reinforcement. Users can indicate the dimensions of the blocks or use blocks designed by manufacturers such as the Spanish company NORMABLOC which designs concrete blocks and masonry.Some walls may contain openings. The program analyses the necessary reinforcement for the openings in the reinforced concrete walls (lintel, sills, lateral and diagonal walls) and the lintel reinforcement if there are openings in concrete block walls. Additionally, users can obtain reports of the checks that have been carried out during the reinforcement design process, which can be viewed on-screen and printed out.The crown beam is also designed for all types of walls as is the intermediate beam at floor level in the case of generic masonry walls and concrete block walls.Beams
Floor slabs may be composed of reinforced concrete, steel (normal or castellated), composite and timber. Corbels can also be introduced.
The following types of slabs can be designed in CYPECAD:One-way
Hollow-core slabComposite slabs (steel deck)CYPECAD allows users to check the ultimate limit state for punching shear of waffle and flat slabs, and mat foundations using two methods: point tangential stress tests and in accordance with design code criteria.Stairs
CYPECAD analyses and designs straight and curved stair slab reinforcement as isolated elements of the structures. The program establishes the reactions on the main structure based on geometry, type, and arrangement of the supports, and applied gravitational loads, which are then applied as line and surface loads (for the steps built on the floor) in the dead and live load loadcases.The program designs stairs using the finite element method, using the two usual loadcases when designing stairs: permanent loading and live loading.CYPECAD displays the reinforcement of each span of the stairwell on screen. It is also possible to view the displacements, forces, and deformed shape of each span in 3D.
The foundations designed by CYPECAD can be: fixed (with footings or pile caps) or floating (with mat foundations and foundation beams, where users have to define the subgrade modulus when applying the Winkler theory).Additionally, the program allows users to analyse the foundations alone (without inserting a superstructure) by defining column starts.
Welded and bolted joints
CYPECAD and CYPE 3D have five modules for analysing and designing steel-section joints.
The Joints I, Joints II and Joints V modules have a wider field of application in warehouses designed using CYPE 3D and with Integrated 3D Structures of CYPECAD, while the type of joints designed by the Joints III and Joints IV modules have a wider field of application in building structures made up of frames that are designed in CYPECAD.In any case, the Joints I, Joints II, Joints III and Joints IV modules have common types of joints that are developed and completed in the same way in each module.
The design load analysis is carried out by means of a 3D spatial analysis using stiffness matrix methods, which contains all the elements that define the structure: columns, reinforced concrete shear walls, walls, beams, and slabs.The deformation compatibility of all nodes is established, considering 6 degrees of freedom, and the non-deformability hypothesis of the plane of each floor is created to simulate the rigid behaviour of the floor slab, preventing relative displacements between nodes of the slab (rigid diaphragm). Therefore, each floor can only rotate and move as a whole (3 degrees of freedom).The consideration of rigid diaphragm for each independent area of a floor is preserved even if beams, not floor slabs, are defined on the floor, except for unconnected beams that users disconnect from the rigid diaphragm and except for walls that are not in contact with floor slabs (from v.2012.a onwards). More information can be found on the "Rigid diaphragm at floor level in CYPECAD" web page.When there are independent areas on the same floor, each of these is regarded as a separate part in terms of the non-deformability of that area and shall not be considered as a whole. Therefore, the floors will act as independent non-deformable planes. A non-connected column is considered as an independent area.For all load states, a static analysis is carried out (except when dynamic actions due to seismic activity are considered, in which case the spectral modal analysis is used) where a linear behaviour of the materials is assumed and, therefore, the first-order analysis, in order to obtain displacements and stresses.Integrated 3D structures always have 6 degrees of freedom per node. More information on integrated 3D structures.Stairs also have 6 degrees of freedom and are developed and completed separately. The program determines the reactions on the main structure, which are translated as linear and surface loads (in the case of steps built on the floor) in the dead load and live load loadcases. More information on stairs.Detailed information on this aspect can be found in the "CYPECAD – Calculations manual”. The manual can be accessed from the main menu of the CYPE programs or from the CYPECAD "Help" drop-down menu.
The seismic analysis is carried out by means of a complete modal spectral analysis which resolves each mode as a loadcase and carries out the modal expansion and the modal combination to obtain the forces.
Detailed information on the seismic analyses is also available in the "CYPECAD – Calculation report" manual, which can be accessed from the main CYPE program menu or from the CYPECAD "Help" drop-down menu.
With the “Fire resistance check module”, CYPECAD and CYPE 3D carry out the following:
The beam editor displays the information of a frame and automatically updates it with the changes made. It provides quick and easy graphical editing (reinforcement, steel sections, solid sections, trusses, connectors, etc.). Users can obtain:
CYPECAD has a column reinforcement editor that:
Other results analysis tools
CYPECAD has a number of tools that allow users to check all graphic results on-screen.After the analysis, users can view the deformed shape of the structure in 3D (with colour scales), produced by simple loadcases or a combination of loadcases. Users can also see an animated view of the deformation process that the selected loadcase combination produces.Displacements, forces, force combinations and quantities of flat slabs, foundation slabs and waffle slabs can be represented on contour plots (coloured graphs where each colour represents a value) and on contour line diagrams (curves connecting geometric points with the same value).It also provides graphical consultation of stress envelopes, deflections, etc.Users can modify the reinforcement of all the elements and then check the modifications for footings, pile caps, beams, columns, and joist slabs.It can automatically match top reinforcement in joist slabs, taking into account length criteria or steel area and length criteria. This way, more uniform reinforcement layouts are obtained, aiding in the construction process.It modifies the reinforcement of waffle slabs and slabs by means of visible tables. Users can copy the reinforcement from one floor to another, modify the geometry after the analysis and insert reinforcement without having to re-launch the analysis.The editor for footings, pile caps, baseplates, and strap and tie beams is an extremely powerful tool that allows users to verify any geometric and reinforcement configurations they have defined. The program provides reports containing all the checks that have been carried out on the foundations and their level of compliance. It is possible to match the geometry, typology and reinforcement of footings, pile caps, strap beams, tie beams and baseplates.
Project plans can be configured in different paper formats and sizes, either standard or user-defined. Furthermore, they can also be drawn by printer, plotter or exported to DXF and DWG format. In the floor drawings, the DXF or DWG files that have been used to define the job can be included. They can be integrated entirely or only the desired layers, such as stairs, for example.A drawing editor is available on the job's own floors, which provides users with a wide range of resources: adding dimensions, texts, sections of the building, construction details in DXF format, floor slab sections, modifying the location of texts, etc. These modifications are saved with the project.CYPECAD has an extensive library of steel, concrete, composite and inclined slab construction details available to be incorporated into any of the drawings generated by the program. This library is also available in two volumes and includes the details in DXF and DWG format:
You can apply any scale, line thickness, font size, title block, etc. This way, the drawing of the plan can be completely customised.CYPECAD provides complete and clear drawings. You can obtain drawings of the layout, floor plan, foundations, beams, column schedule, detailing of columns and shear walls, foundation loads, wall elevations, stair detailing, loads, corbels, etc. They optionally include measurement tables and reinforcement details. These can be configured so that each user can obtain the drawings according to their needs. CYPECAD has an editor that allows text to be moved while viewing the drawings on screen.Reports
Users can easily obtain reports of all the data entered and the results: list of project data, combinations used in the analysis, foundations, corbels, envelopes, reinforcement and quantities of all the elements, job ratios, horizontal wind loads, participation coefficients (seismic loads), second order effects, etc.All this can be obtained either on screen or by printer, but files can also be created in HTML, DXF, DWG, RTF, PDF formats, etc.The reports that are generated include the following:
Exporting in IFC format
CYPECAD allows all the designed structural elements to be exported in IFC format (Industry Foundation Classes - versions 2x3 or 4).As well as being the format by which all the programs included in the Open BIM workflow exchange information, CYPECAD also generates files in IFC format without being linked to an Open BIM project to generate these files so that the information generated in CYPECAD can be read in CAD/BIM programs such as Allplan®, Archicad®, Revit® Architecture, etc.This connection mode with other CAD/BIM software loses some of the considerable advantages of the Open BIM workflow, but it is another feature that has been available in CYPECAD since earlier versions.In order to carry out these exports, CYPECAD has the "Export in IFC format" option (File menu > Export).The "Export in IFC format" dialogue box (File menu > Export > IFC) allows users to choose different variations of the IFC format to generate the export file:
CYPECAD exports the following elements to IFC format:In one-way slabs
In composite slabs
In post-tensioned slabs
CYPECAD also allows IFC format files generated by CAD/BIM programs to be imported, thanks to its Automatic job introduction module: DXF, DWG and CAD/BIM models. More information at the CYPECAD Introducing the structure website.In order for CYPECAD to export the work in IFC format, the user license does not need to have the "Automatic job introduction: DXF, DWG and CAD/BIM models" module.
CYPECAD and CYPE 3D use the potential offered by multiprocessors in the analysis of their structures.To access these features, CYPECAD and CYPE 3D have two common modules that save a considerable amount of analysis time:
