As of version 2025.d, the representation colours of the different elements are configurable.
This customisation is carried out from the "Project > Settings" menu, where the colours can be edited according to the user's preferences.
This feature is made even more relevant by the new tools, incorporated in this version, to include images in the connection reports.
As of version 2025.d, the contour plot result views include a new option to show or hide the finite element mesh.
Up until version 2025.d, the shear check of the bolts was carried out considering the worst-case scenario: the shear plane passing through the threaded zone of the thread.
As of version 2025.d, depending on the plates to be joined and the length of the shear plane, the program evaluates whether the cutting plane is on the threaded or non-threaded part of the thread.
When the thicknesses of the plates to be joined are different, the cutting plane may vary according to the direction in which the bolt is placed, passing through one area or the other. In these cases, the bolt shall be evaluated in both directions and, if in any of them the cutting plane passes through the threaded area, this condition shall be considered in the check.
The length of the shear plane is included in the bolt library. The series of bolts available in the program have been updated to incorporate this information. In projects created with previous versions, the bolt libraries will assign the threaded area a length equal to the length of the thread, as was previously the case.
The libraries can be updated via the library management to include the length of the shear plane. To do this, simply click on the blue arrow icon and select the series to be imported. If you have a customised user library, the same procedure must be followed to update the bolt libraries and then save the customised library again.
In version 2025.d, the import of the nodes defined in the structural model has been implemented.
This task can be carried out in the import of structures from CYPE 3D, ETABS® or SAP 2000®. A node will be created with the same reference as the node in the structural model and with the same bars.
In previous versions, geometric detection was carried out based on the ends of the bars.
As of version 2025.d, a small diagram with the layout of the bolts for each operation will be included in the section on the definition of the bolts in the summary report.
The index drawing of each bolt, anchor or timber fastener has been implemented in the 3D view of the connection.
The options to show or hide these indices are enabled under "View options".
In version 2025.d, a tool has been implemented to define the loads applied to each bar based on the mechanical properties of its section. In the load edition panel, on the force table for each bar, the wizard for modifying the forces of the selected load case appears.
This tool changes the table value of each force by the new value calculated from a user-defined factor, the mechanical properties of the bar section and the yield strength of the bar steel. The factor can be defined with a positive or negative sign. To the right of each force activated by the user, the calculated force is displayed. On the right side of the panel, the mechanical properties of the bar section are displayed.
This tool is useful, for example, when it becomes a requirement to design the connections with a higher strength than that of the connected bars, as mentioned in different seismic design regulations.
Up until version 2025.d, any modification to the operations resulted in the loss of the results of the finite element model, even when these changes didn't affect the analytical model. However, as of version 2025.d, the results will be retained as long as the modifications do not alter the analytical model, with only the necessary checks being updated.
Parameters that can be changed without any loss of analysis results include the following:
As of version 2025.d, connection reports can include images of the connections.
In the "Model" and "Analysis" tabs, the "Images" section has been added to the toolbar ribbon. This section offers a tool for snapping images, as well as a library for managing them.
By clicking on "Snap image", a snap of the 3D view is generated and saved in the image library. Users can assign a reference to it, which will be the text shown at the bottom of the image in the list. Furthermore, depending on the type of 3D view, the image has a specific type, which determines in which chapter of the report it will be included.
The size of the images in the report is set by default, although users can scale the images according to their needs.
As well as snaps of the 3D views, additional images can be added to the library. To do so, simply click on the "Add" icon in the list of images in the library.
In the connection analysis model, one of the bars is set as the load-bearing element, unless a baseplate has been defined. The remaining bars are connected to this element, on which the loads are applied.
Up until version 2025.d, the bars connected to the load-bearing element had no external links, allowing users to define forces in the direction of each axis and moments around each axis.
This is the default model and the one used in previous versions. The end of the bar has no external links, allowing the six forces to be defined.
These new models are useful for dealing with different structural situations. For example:
Case 1
The hollow section bar is hinged in the structural model and connected by a single bolt. If the unrestrained model is used, an unstable mechanism can be generated (Case 1 - A). By changing the load model to N - Vy - Vz, the local model of the connection resembles the connection conditions in the global model of the structure (Case 1 - B).
Case 2
Two angles are connected, where one acts as a load-bearing element and the other receives a tension applied at the centre of gravity of the section. If the unrestrained model is used, the eccentricity between the load and the connection of the load-bearing section generates a penalising moment (Case 2 - A). By changing the loading model to N - Vy - Vz, a more balanced stress distribution between the two sections is achieved (Case 2 - B).
Case 3
The eccentricity of the diagonal bar generates a moment that penalises the haunch. In this case, the displacement out of the plane formed by the beam and the diagonal is constrained, so the local model of the connection is more similar to the global model by selecting the N - Vz - My model (Case 3 - B).
In CYPE Connect and StruBIM Steel version 2025.c, INDEX brand chemical anchors for concrete fixings have been incorporated as concrete fixing elements in baseplates.
These elements are checked in accordance with the criteria in EN 1992-4:2018, based on the data provided in the ETAs (European Technical Assessment) of these anchors.
Version 2024.f changed the way bars were exported and imported between CYPE 3D and CYPE Connect and StruBIM Steel from an IFC format to an exchange file in JSON format. As of this version, the bars of the sections supported by the connection editor were exported.
Now, as of version 2025.c, all other sections supported by StruBIM Steel will also be exported and imported, in addition to the tag assignment that the bars had in CYPE 3D.
