Exporting portal frame reinforcement bars to StruBIM Rebar

In version 2023.e, the export of rebars is carried out per span or for the whole portal frame, depending on the assembly options selected.

  • For the "Continuous assembly reinforcement in the span - At workshop" option, the reinforcement is exported as a group by spans.
  • For the "Stirrup-carrying reinforcement" and "Continuous assembly reinforcement in the span - On site" options, the export is carried out in groups of complete portal frames.

"Divide reinforcement" option in the portal frame editor

In version 2023.e, the "Divide reinforcement" option has been added, allowing rebars to be divided at the indicated point.

Limit drift between floors due to seismic action

In version 2023.c, the limit drift between floors due to seismic action was implemented in CYPECAD by means of user-entered values.

Now, in version 2023.e, the limit drift between floors due to seismic action can be selected for several codes.

An automatic selection can be made according to one of the codes in which the drifts have been implemented, or the values can be entered manually.

An indication is given in the final report of the analysis if any of the elements do not comply with any of the selected limits.

The codes in which the limit drift between floors due to seismic action have been added in version 2023.e are:

Minor improvements and corrections

CYPECAD version 2023.d includes the following improvements and corrections of the program for certain cases:

  • Envelope > Forces in beams
    • An error that used to occur upon selecting "Envelope > Forces in beams" when one of the older concrete codes supported by the program was selected for the job has been fixed.
    • An error that occurred upon selecting "Envelope > Forces in beams" when the combinations selected by default were not active because there were no elements of that type in the current floor, has been solved. This occurred, for example, when trying to check the envelopes or combinations in a floor in which only concrete elements had been defined when, by default, the "Laminated steel" combinations were active due to the fact that these were the last combinations checked in the last job that was opened.

  • Project > General options > Limit drift between floors due to seismic action
    An error that occurred when selecting "Project > General options > Limit drift between floors due to seismic action" if the job had no seismic code activated has been fixed.

  • Changing column material
    An error that occurred when changing the material of a circular column from steel to timber has been fixed.

  • “Drift between floors due to seismic action” report
    • The "Drift between floors due to seismic action" report has been improved when considering the second-order effects of seismic action.
    • An error that occurred in the "Drift between floors due to seismic action" report when selecting "Interaction with the structure" in "General data > Building elements" has been fixed.

Graphical editing of the reference system of the model

Since version 2022.a, the applications integrated within the Open BIM workflow via the BIMserver.center platform include a tool for managing project reference systems. This option is available from the configuration window that appears when linking or updating a BIMserver.center project via the "Geographic location and reference system" option. As of version 2023.d, the applications now allow users to run a graphical environment where they can visually define a reference system for their model. To do this, the "Geographic location and reference system" window now contains the "Visual editing of the local reference system of the model" option.

From the "Visual editing of the local reference system of the model" window, the origin and orientation of the reference system of the model can be indicated in the workspace with the "Define the reference system of the partial model" tool. Both the axes of the reference system of the model, which we have just entered and the axes of the reference system of the site can be viewed in the workspace. The latter appears with a "Site" tag.

To make it easier to define the reference system, the 3D models corresponding to the BIMserver.center project contributions selected during the linking process are displayed. The management of the visibility and object snaps of these models is carried out from the "Elements read" menu in the left sidebar of the window. The "Views" menu can also be found in the same options bar, from which different types of 2D and 3D views of the model can be generated. These tools can already be found in several CYPE applications. For more information on how they work, please refer to the User’s Manual for the 3D work environment tools available in CYPE applications.

Apart from 3D models, 2D drawings or plans can also be imported from CAD files (".dxf", ".dwg", ".dwf") or images (".jpeg", ".jpg", ".bmp", ".png", ".wmf", ".emf", ".pcx"). These files and object snaps are managed through the "DXF-DWG Template" and "Template object snaps" options accordingly.

Once the editing is complete, the coordinates and orientation of the reference system of the model with respect to the reference system of the site are moved to the corresponding fields in the "Geographic location and reference system" window.

Font size

The "Font size" option has been added to the general configuration menu of the applications. This tool allows users to increase or decrease the basic size of the font used in the user interface of the programs. Thanks to this implementation, the accessibility of the applications has been improved while also ensuring the correct visibility of the content on devices with different screen resolutions.

To enter a "Basic size" the "Set custom font size" option must be checked. The size users can enter is the application's basic font size. Any other font sizes that may exist in the program's interface will be automatically modified proportionally according to the change in the basic size.

It is important to note that, as this is a common parameter, its modification will affect all installed CYPE tools.

CYPECAD "Health and safety" tab

As of version 2023.c, CYPECAD no longer includes the "Health and safety" tab. The features of this CYPECAD tool for drawing up plans of collective protection elements are largely superseded by the "CYPE Health and safety" program.

CYPE Health and safety can be downloaded from the BIMserver.center platform and, ever since this application was implemented in version 2019.a, the permissions that allow its use are the same as those that provide access to the CYPECAD "Health and safety" tab.

Installation in Polish

As of version 2023.c CYPECAD can also be installed in Polish.

Other improvements and corrections

CYPECAD version 2023.c includes the following program improvements and corrections for some specific cases:

  • Beam interchange report
    The “Beam interchange file” with the Spanish structural code "Código Estructural" has been improved. Some reinforcement bars were not correctly dimensioned.

  • Exporting flat slab and waffle slab reinforcements
    Exporting reinforcement from waffle slabs and flat slabs to StruBIM Rebar has been improved. Occasionally, when a reinforcement group had a change of direction at the edge of the slab, reinforcement could be generated outside of the edge of the slab.

  • Editing column reinforcement
    The diameter of a rebar can now be selected by opening the drop-down menu with the down arrow key. Previously, clicking with the mouse was required.

  • Column forces
    The panel for checking the forces at column starts has been improved, the values of the shear forces and moments were interchanged.

  • Frame deflection groups
    The editing of frame deflection groups has been improved. Sometimes they were not modified correctly.

  • Selecting codes
    The selection of codes that appears by default when creating a new job has been improved. Since the timber code was added, the laminated steel code did not start with the same value as the value of the last job created.

  • Exporting the data used by the Open BIM Quantities program to the BIM project
    The export to the BIM project has been improved so that the Open BIM Quantities program can correctly identify the elements of the integrated 3D structures.

  • Importing walls from a BIM project
    The import of walls from a BIM project has been improved. In some cases, where walls were partially connected to columns, some spans of the wall were not imported.

  • Sharing in the BIM project
    An error that occurred when sharing CYPECAD information in the BIM project ("BIMserver.center" button > "Share" option) when there were shear walls in the job and the "Interaction of the structure with the building elements" option was selected, has been solved.

  • Exporting the bill of quantities
    The export to FIEBDC-3 (BC3) format has been improved ("File" menu > "Export" "Bills of quantities"). The information required for importing into OpenBIM Quantities is now not included, it is only included when using the "BIMserver.center > Share" option. This information made it difficult to identify the elements when importing the BC3 file into any other program.

  • Surface loads
    The introduction of surface loads has been improved. Previously, with the grey or white screen background, the display of the contour when entering the first load was correct (blue colour), but in the following loads that were entered this colour was that of the contour infill, and in some cases, it was hard to see which contour was being entered.

  • Construction process
    The "Edit groups - Construction process" panel has been improved. The "Save as default settings" option in the panel was not working properly.

  • 3D reinforcement display
    The display of reinforcement in 3D has been improved. Previously, the reinforcement of stirrups at the column start with overlaps at mid-height was not displayed correctly.

Checking the forces of beams and joists

The checking of forces in beams and joists has been improved. It is now possible to check S.L.S Characteristic combinations, S.L.S. Frequent combinations and S.L.S. Quasi-permanent combinations.

Selecting columns in plan view from the column schedule

The “Plan view” option has been added to the column schedule editing ("Results" tab < "Columns/Shear walls" menu > "Edit" option > select a column > tab "Edit in column schedule" > "Plan view" option in the "Options" tool group). 

This option is compatible with certain tools (Match, Modify, Divide, Redesign group reinforcement, etc.) and allows the column selection for applying the tool to be carried out in a plan view instead of on the column schedule. This is helpful when using tools such as "Match" in large jobs, as it makes it easier to locate the columns when this mode is activated.

Assigning base reinforcement in panels by means of a filter

The "Assign in accordance with filter" option has been added (Slabs menu > Assign base reinforcement > "Assign in accordance with filter" button). With this option, users can assign the desired base reinforcement to the slabs that are the result of applying the selected filter. The filter can be applied to the current group, to all groups or to a group selection.
