CYPECAD

"Parapet" type construction elements

In previous versions, the construction elements that could be entered in CYPECAD were defined between groups ("Beam definition" tab > "Loads" menu). Now the possibility to enter "Parapets" has been implemented. Parapets are defined in the same way as the construction elements between groups, but instead of specifying the end group, the height of the parapet must be defined.

Parapets will not be included in seismic analyses, as opposed to partitions.

When importing a BIM project, elements whose "IfcWallTypeEnum" property is "PARAPET" shall be automatically marked to be imported as construction elements of the "Parapet" type. If they do not have this property, they can be marked manually in order to be generated correctly.

Exporting enough data on structural elements with steel sections to the BIM model in order to allow their quantities to be generated

As of version 2023.b, CYPECAD exports the quantities of the IFC standard ("IfcQuantitySet") related to structural elements with steel sections to the BIMserver.center project. These quantities can be read by other applications integrated in the Open BIM workflow via the BIMserver.center platform.

For example, the Open BIM Quantities tool can use this information for generating the bill of quantities.

Editing deflection groups in beam frames

In version 2023.b, three options have been added for editing the deflection groups of beam frames. Up to this version, deflection groups were generated automatically and no changes could be made. These options are as follows:

  • Automatic
    Allows users to automatically generate the deflection groups.

  • Edit
    Allows users to modify the "Support conditions" and deflection type for each deflection group.

  • Join / Divide
    Allows users to join and divide deflection groups. When selecting a node between two deflection groups, those groups will be joined together. Selecting a node inside a deflection group will split that group.

Implementation. PN-EN 1992-1-1:2008/NA:2016-11 (Poland)

Polish National Annex to Eurocode 2 (Design of concrete structures. Part 1-1: General rules and rules for buildings).

Implemented in CYPECAD, CYPE 3D, Reinforced concrete cantilever walls and Embedded retaining walls, for the analysis and design of concrete structures.

Other improvements and corrections

CYPECAD version 2023.a includes other minor improvements and corrections of the program for certain cases:

  • Deleting jobs
    In “File management” (“File” menu), several jobs can be selected in order to delete them simultaneously.

  • Floor diagram in the "Import of BIM models"
    In the "Floor plans" section of the "Import of BIM models" wizard, a floor plan diagram has been added to visually check if the floor plan dimensions to be imported are as expected.

    In some cases, the diagram does not appear because the information exported to the IFC file by the program where the model has been designed has not been generated according to the IFC standard. The best solution for these cases would be for this information to be exported correctly but, if this is not possible, the "Zo" value of "Local reference system of the model" in "Geographical location and reference system" can be modified. At this stage of the import wizard, the necessary instructions are given to match the plant dimensions to the expected ones.

  • Import of BIM models - Columns
    The fixed point of columns in BIM projects designed with CYPE Architecture is imported.

  • Improved selection of reinforced and prestressed joist floor slab sheets
    As of version 2023.a, users can select a card containing a concrete with a lower "fcd" than the one selected in the job.

  • Updating a BIM project
    An error that occurred when updating a BIM project after adding a floor with beams to the project has been fixed.

  • Reorganising beam alignments
    The warning message that appears when using the "Reorganise" option in the "Beam alignments" dialogue box ("Beam definition" tab > "Beams" menu > "Beam alignments") if there are alignments with previously assigned references has been improved.

  • Inertia reduction factors
    The values of "Inertia reduction factors" have been modified when the selected seismic code is 'P100 - 1/2013 (Romania)'. Previously they were the default values; now they are the values indicated by this code.

  • Generic column reinforcement with asymmetrical transverse section
    The generation of generic column reinforcement with asymmetrical shapes has been improved. In some cases, this reinforcement was generated with interchanged axes.

  • Beam assembly reinforcement tables
    The editing of the beam assembly reinforcement tables has been improved in order to allow the same entry to be used in different width and/or depth ranges.

  • Sloped beams
    The entry of sloped beams has been improved. After selecting the first point the zoom setting is maintained. Previously it was changed in order to display a complete view of the floor plan.

  • Concrete column resistance
    Four decimal points are allowed in "Concrete resistance > Reduction coefficient to be applied to the concrete resistance".

  • Adjusting beams
    In the "Beams > Adjust" option, the template snap has been improved. Previously, in some cases, the desired line could not be selected from among all the lines in the template when they were in close proximity to the beam.

  • Improved drawing of walls arranged on top of other walls
    On rare occasions, the drawing of one wall on top of another in the initial group of floors of the wall was not carried out correctly.

  • Importing jobs from CYPE 3D
    The import of CYPE 3D works as integrated 3D Structures has been improved. As of version 2023.a, jobs with user-defined project situations can be imported.

Improved design and checking of beams and columns with the Spanish structural code "Código estructural" and the Eurocodes

Two options ("Slope angle of the compression struts" and "Tolerances in spacing checks") and several improvements have been implemented in order to optimise the check and design of beams and columns. These options and improvements are available for the following codes:

  • Eurocode 2 (EU)
  • Eurocode 2 (Spain)
  • Eurocode 2 (Portugal)
  • Eurocode 2 (France)
  • Eurocode 2 (Romania)
  • Eurocode 2 (Malaysia)
  • Eurocode 2 (Singapore)
  • Código Estructural (Spain)

These new options can be accessed via the “General data” panel:

  • General data > Bars > By position > Options for columns, shear walls, walls and corbels > Design / Code checks.
  • General data > Bars > By position > Beam options > Design / Code checks.

The new options and improvements are detailed below:

  • Slope angle of the compression struts
    Allows the angle between the compressed concrete struts and the longitudinal axis to be defined, which is to be considered in the shear resistance analysis. The program allows users to assign one general slope angle for the struts in all the columns of the structure, and another one for all the beams of the structure.
  • Values can also be assigned individually to columns and beams using the following options:
  • For columns
    Column definition tab > Columns, shear walls and starts menu > Slope angle of the compression struts.
  • For beams
    Beam definition tab > Beams menu > Other options > Assign the slope angle of the compression struts.
  • Tolerances in spacing checks
    The “Tolerances in spacing checks” option has been added for beams and columns. This option allows the value of the tolerance that is permitted when carrying out the minimum and maximum spacing checks between reinforcement bars to be defined. If the difference in absolute value between the value required by the code and the calculated value is less than the tolerance considered, the check is compliant.
  • Analysis of the spacing between transverse reinforcement crossties
    The analysis of the spacing between transverse reinforcement crossties has been improved.
  • Analysis of the concrete area for circular composite columns with embedded sections
    The analysis of the concrete area for circular composite columns with embedded sections has been improved. The radius of the circular concrete section is taken as the minimum value between "the actual section radius" and "the maximum radius permitted by the code", which defines limits for the maximum thickness of the concrete cover in fully embedded sections.

Beam intersections references

The “Beam intersections references” option has been added to the “Groups” menu of the “Beam definition” and “Results” tabs. These references can now be generated automatically according to the order of the frames.

For jobs created from version 2023.a onwards, this will be the default option. For jobs that have already been created, the order in which they were generated is maintained, but the "Beam intersections references" option can be used to change the order.

Exporting the rebars of shear walls and stairs to the BIM model

The rebars of shear walls and stairs can now be exported to the BIM model.

In the current version of the program, CYPECAD exports the reinforcement of the following types of elements:

  • Concrete walls
  • Columns
  • Shear walls
  • Beam frames
  • Stairs
  • Foundation elements (footings, pile caps, strap beams and tie beams)
  • Slabs (waffle slabs, joist floor slabs, hollow core plate floor slabs, composite slabs and flat slabs) 
  • Corbels

This reinforcement can be viewed in the StruBIM Rebar program along with the reinforcement exported from StruBIM Shear Walls.

They can also be viewed in CYPECAD in the "Results" tab (Groups menu > 3D view with details).

Automatic import of structural walls from a BIM project

As of version 2023.a, structural walls defined in a BIM project can be imported. This option is available both for projects modelled using our CYPE Architecture tool and for projects created with other BIM modellers.

Exporting in FBX format

Version 2023.a of all CYPE programs that have the "Print/Save the current view" tool (usually all programs that display graphic information in a window) allows any generated 3D model to be exported in FBX format. This is one of the most common and accepted formats among rendering software (Twinmotion, Enscape, Sketchup+Vray, among others).

Exportation in FBX format is found in the dialogue box that opens when selecting the "Print/Save the Current View" button in any of the programs that include this tool. This feature allows users to export any element that is visible in the current window at that moment in FBX format (as well as elements that have been imported from other programs).

"Channel with stiffened web" type in BS 5950-5:1998 cold formed steel sections

In version 2022.e, "Channel with stiffened web" type cold formed steel sections have been included for beams and columns (CYPECAD) and for bars (CYPE 3D) when the selected standard is BS 5950-5:1998.

Other improvements and corrections

Version 2022.e of CYPECAD includes other minor improvements and corrections of the program for certain cases:

  • Final design report
    In the final design report, warnings concerning concrete wall checks have been added.

  • Checking the results of wall openings
    An error that occurred when checking the results for wall openings when these were defined on a floor with continuous reinforcement has been fixed.

  • Editing frames
    When editing beam frames, the possibility to define "Length with straight extension" in "Longitudinal reinforcement > Edit hooks" has been added.

  • Checking fire resistance
    An error that could sometimes occur when checking a series of steel sections in beam frames, when checking fire resistance, has been fixed.

  • Sharing in BIMserver.center
    The "BIMserver.center > Share" option panel has been improved, it was not displayed correctly at times when the screen resolution is small.

  • Sharing in BIMserver.center
    An error that could occur in the "BIMserver.center > Share" option when generating the reinforcement for column starts has been fixed.

  • Punching shear check
    An error that occurred in the punching shear check process when there is a mat foundation with a very small surface in contact with a column has been fixed.

  • Deleting or dividing groups
    An error that occurred when deleting or dividing a group in the case of walls with blocked reinforcement has been fixed.

  • Beams information
    An error that occurred when selecting a wall that starts on top of another wall in the "Information - Beams" option has been fixed.

  • Bills of quantities
    The measuring of formwork for beams in the "Bills of quantities" option has been improved. In some cases, an element with a 0 m2 surface was added.

  • Changing a job’s code (EHE-08 to Código Estructural)
    The transformation of a job initially created with code EHE-08 when it is updated to code "Código Estructural" has been improved. As well as adapting the "Environment" selection in "General data", it is adapted in each beam that has a specific assignment.

  • Checking the baseline shear
    The checking of the base shear for walls without external fixity in contact with column starts with external fixity has been improved.

  • Checking geometry
    An error that occurred in the "Check the geometry of the current group" and "Check the geometry of the current group and higher groups" options, if sloped beams had been introduced in the job, has been fixed.

  • Analytical model
    An error that could sometimes occur when obtaining the analytical model of a wall whose axis did not match the centre and that ended in a sloped slab has been fixed.

  • Assign walls
    The "Assign walls" option has been improved in order to consider embedded or crown beams with specific features.
