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:


  • + Columns (concrete, steel, composite, and timber), shear walls (concrete) and walls (concrete, masonry, and block walls).
  • +  Beams
  • +  Concrete, steel, and composite.
  • +  Slabs
  • +  One-way slabs, hollow-core slabs, composite slabs, waffle slabs, flat slabs, post-tensioned slabs (one-way, waffle, and flat).
  • +  Node and bar structures
  • +  Concrete, steel, aluminium, timber, and generic material (only forces are analysed in this last case)
  • +  Foundations
  • Slabs, foundation beams, footings, and pile caps
  • Steel connections
  • Welded and bolted (including the baseplates).
  • Flat shells
  • Force analysis of concrete, rolled steel, cold-formed steel, aluminium, or generic-material shells.


Data Entry

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
  • Material selection
  • Design options and reinforcement tables
  • Load definition
    Dead loads, live loads, wind, seismic loadingfire resistance checks, additional loadcases.
  • Column buckling coefficients
  • Conditions for beams and pile caps


Structure geometry

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.

  • Manual insertion using global or relative coordinates
    This can be combined with all other introduction methods at any time.
  • Manual insertion assisted by DXF and DWG files used as templates
    This can be combined with all other introduction methods at any time.
  • Automatic insertion by importing a CYPE 3D structure
     This can be combined with all other introduction methods at any time.
  • Automatic insertion by interpreting DXF or DWG file information
    This is an initiating procedure. It can be combined with all other procedures except for importing files in IFC format and connecting to the BIM model.
  • Automatic insertion by importing files in IFC format, generated with CAD/BIM programs
    This is a launching procedure. It can be combined with all other procedures except for DXF or DWG file interpretation and connection to the BIM model.
  • Importing data using by linking to an Open BIM model
    This is a launching procedure. It can be combined with all other procedures except for DXF or DWG file interpretation and connection to the BIM model.

This versatility adds speed, reliability, and efficiency to the process of introducing a structure.


Analysed structural elements


The structural supports that CYPECAD analyses and designs are:

  • Columns
    • Reinforced concrete columns
      Rectangular, circular, and polygonal section.
      More information
    • Steel columns
      Rolled, reinforced and cold-formed steel columns.
      More information
    • Composite steel and concrete columns
      Embedded concrete-cased sections or closed concrete-filled sections
      More information
    • Timber columns
      Rectangular or circular-section timber columns
      More information
  • Shear walls
    • Rectangular
    • Any geometric shape composed of rectangles

  • Walls
    • Reinforced concrete walls
    • Plane stress walls
      More information
    • Generic masonry walls
    • Concrete block walls
      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.


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:

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.
More information on Punching shear verification.


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.

More information at:


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.

  • Pad footings
    These can consist of reinforced concrete or mass concrete, be for a single or combined for multiple supports (columns, shear walls and walls), which can be placed freely on the foundation element.

  • Pile caps
    They can hold a number of supports (columns, shear walls and walls), and can be placed freely on the foundation element.
    A wide range of types are available:
    • Rectangular pile caps for one, two, four and five piles
    • Triangular pile caps for three piles
    • Strip pile caps for three to thirty piles
    • Rectangular pile caps for multiple piles (grid distribution from three to thirty piles per side)
    • Pentagonal pile caps for five or six piles
    • Hexagonal pile caps for six or seven piles
  •  Strap beams and tie beams
    Act on footings and pile caps.

  • Mat foundations and foundation beams
    The mat foundations and foundation beams are considered to be supported on an elastic foundation (ballast coefficient method), according to the Winkler model, based on a constant of proportions between forces and displacements, the value of which is the ballast coefficient.

    Foundation beams and mat foundations are part of the overall structure and therefore interact with the rest of the structure (they are part of the overall stiffness matrix of the structure). Therefore, loads can be applied to these elements, as well as to any beam or slab of the structure they are part of.

    The limit states to be checked are those applicable to the design of reinforced concrete elements (ultimate limit states), and force, equilibrium, and uplift checks (serviceability limit states).

    CYPECAD carries out checks for shear and punching shear in mat foundations and foundation beams.

  • Base plate
    For any steel column arrangement (simple and composite sections).

Welded and bolted joints

CYPECAD and CYPE 3D have five modules for analysing and designing steel-section joints.

  • Joints I. Welded. Warehouses with rolled and welded steel I-sections
    More information
  • Joints II. Bolted. Warehouses with rolled and welded steel I-sections
    More information
  • Joints III. Welded – Building frames with rolled and welded steel I-sections
    More information
  • Joints IV. Bolted. Building frames with rolled and welded steel I-sections
    More information
  • Joints V. Flat trusses with hollow structural sections
    More information

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.

Design load analysis

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.

Seismic analysis

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.

More information at CYPECAD. Seismic analysis:

  • Effect of non-structural construction elements on buildings’ seismic behaviour
  • Seismic design criteria by capacity for supports and concrete beams
  • Base shear correction
  • Fundamental period of the structure with user value
  • User-specified seismic spectrum

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.

Fire resistance check

With the “Fire resistance check module”, CYPECAD and CYPE 3D carry out the following:

  • For steel and concrete structural elements
    Fire resistance checks and the design of protective coatings in accordance with the selected code.
  • For timber sections
    Fire resistance checks and the design of timber sections against fire action, so they comply with the selected code.

More information on Fire resistance checks.

Results Analysis

Beam editor

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:

  • Detailed U.L.S (Ultimate Limit State) and S.L.S (Serviceability Limit State) check reports for concrete beams (with checks for failure due to torsional stress and design criteria for seismic loads)
  • U.L.S and S.L.S. reports for steel beams
  • Required and effective reinforcement area graphs
  • Bar bending diagrams and reinforcement configuration options on the frame drawings
  • Horizontal and vertical openings in concrete beams
  • Rectangular variable-section dropped beams

More information on Beam editors in CYPECAD.

Column editor

CYPECAD has a column reinforcement editor that:

  • Shows all data related to their design and verification and generates detailed reports of the ultimate limit state (U.L.S.) checks that are carried out.
  • Allows users to organise column schedule groups.
  • Checks any modifications that have been undertaken.
  • Redesigns reinforced concrete and steel columns.

More information on Column editors in CYPECAD.

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. More information on foundations.



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. More information on:

  • Construction Details library, Inclined slabs
  • Construction Details: steel, concrete and composite

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.


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:

Detailed ultimate limit state check reports

CYPECADCYPE 3D and the Portal frame generator generate detailed ultimate limit state (U.L.S.) check reports. The U.L.S. reports contain all the checks these programs carry out to design concrete, steel, aluminium and timber elements. Each check refers to the design code and article requiring the check, or the criteria which have been applied to carry it out. The detailed contents of the U.L.S. reports make these essential documents with which users can verify, justify and optimise the design of the structural elements that have been analysed.

The level of detail of these reports also acts as a guide allowing users to know all the checks to which the structural element is submitted.

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:

  • IFC 2x3
  • IFC4
  • IFC 2x3 for Revit (versions 2012, 2013 and 2014)
  • IFC 2x3 for Archicad
  • IFC 2x3 Allplan (version 2014 and earlier)

CYPECAD exports the following elements to IFC format:

  • In one-way slabs
    • Reinforced joists
    • In situ joists
    • Steel joists
    • Open-web joists
    • Forms
  • In composite slabs
    • Slab plates
    • Concrete layer
  • In post-tensioned slabs
    • Tendons

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.

Analysis using multiprocessors

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:

  • Parallel analysis with two multiprocessors
  • Parallel analysis with up to eight processors

More information

Codes included in the user license

Depending on the country from which the licensee acquires the license, only the code implemented in each program is activated for working in that country.

More information on this aspect and on the possibility of acquiring codes not initially included is available on the Design codes implemented in the user license webpage.

CYPECAD versions and modules

CYPECAD versions

CYPECAD is available in its unlimited version and also in two limited versions called LT30 and LT50, which contain the same tools and module acquisition possibilities, but have the following conditions:


  • Fifty columns
  • Four floor groups (Floor group: floors which are the same and consecutive)
  • Total of five floors
  • Walls: one hundred linear metres


  • Thirty columns
  • Four floor groups (Floor group: floors which are the same and consecutive)
  • Total of five floors
  • Walls: one hundred linear metres

Integrated 3D structures of CYPECAD (also LT50 and LT30) is not technically a module. To define these 3D structures in CYPECAD, users must also have the required permits to use CYPE 3D in their user license and, optionally, modules that are exclusive to CYPE 3D.

Other features

CYPECAD modules

In order to access further features offered by the program, there are several modules that can be found on the “CYPECAD modules” webpage.

Interoperability with other systems

CYPECAD3D structures integrated into CYPECAD, and CYPE 3D can export the analysed and designed structure to TEKLA Structures. More information on export options can be found at How to export from CYPE to TEKLA® Structures?

Mininum system requirements for installing and using CYPE programs

Generally, the minimum system requirements and particularly the recommended system requirements for the proper functioning of the operating systems available on the market are higher than those for installing and using CYPE programs:


Intel Celeron

Intel i3, i5, i7 or i9


AMD A8/A10 or FX series

AMD Ryzen and Threadripper

Operating system

Windows 2008 Server

Windows 2012 Server

Windows Vista

Windows 7

Windows 8.1

Windows 10

With the exception of Windows 10 and Windows 2012 Server, all other systems can be either 32-bit or 64-bit.

BIMserver.center programs are 64-bit. To install them, a 64-bit operating system is required.


A minimum of 8 gigabytes (GB) is recommended for Windows Vista, 7, 8.1 or 10. However, 32-bit operating systems only support a maximum of 4 GB.

Display resolution

Minimum resolution of 1366 x 768 pixels and 16-bit colour.

Free hard drive space

For installation

The amount of free hard drive space required depends on the installation being carried out, as you can install either the complete package or individual programs. The screens at the beginning of the installation process will display the minimum free space required for the installation that has been selected.

To install the complete package of our programs, 23.6 GB of free hard drive space is currently required. This value may vary depending on the version being installed.

For running the programs

The amount of free hard drive space required for running programs is highly variable and depends on the size and number of jobs to be stored on the hard drive.

Project sizes can vary from a few MB for a small project in CYPECAD or a small bill of quantities in Arquimedes to more than 1 GB for large projects.

USB port

A USB port is required to insert the security key if it is a physical one.

Network cards and TCP/IP protocols

These are required when using a network hardlock and for Internet access of electronic licenses and software linked to BIMserver.center.


Compatible with Microsoft technology.

Graphics card

Must be 100% compatible with OpenGL 3.3 or higher. Therefore, NVIDIA (GeForce) or AMD cards are generally recommended. Furthermore, the latest driver update for the graphics card should be installed.

In some cases, the laptop manufacturer may transform these drivers for compatibility, so the card’s own drivers may not work. If this is the case, check the computer manufacturer’s website and update the card’s drivers from there.


The devices currently available on the market exceed all the indicated requirements. However, as an example, the following settings are displayed for a computer that showed excellent results in the process times according to the tests carried out by CYPE:

PROCESSOR: Intel i7 12MB cache

MEMORY: 16 GB DDR4 2400




Multiprocessor analysis

For computers with multi-parallel processing, users will be able to save a considerable amount of time in the program analysis process by using the corresponding modules.

More information on these modules and a comparative study showing analysis times with and without their use can be found on Multiprocessors.

CYPE software does not use GPUs in any analyses except for some processes related to our virtual reality technologies. In these cases, an NVIDIA GeForce GTX 1060 graphics card or higher is recommended. Otherwise, the recommended system requirements for the optimal functioning of these technologies are those described above.
