New design models for bars
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.
- N - Vy - Vz - Mx - My - Mz
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. - N - Vy - Mz
This model defines loads in the XY plane. The end of the bar is constrained for displacement in the z-axis and rotation in the y-axis. - N - Vz - My
This model defines loads in the XZ plane. The bar end is constrained for displacement in the y-axis and rotation in the z-axis. - N - Vy - Vz
In this model, the end of the bar is constrained for rotation and no moments can be inserted.
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).

Importing structures from an XML file generated by SAP2000®
As of version 2025.c, Sap2000® structures can be imported into CYPE Connect and StruBIM Steel.
An XML file containing all the tables of the model definition and the bar force tables (ANALYSIS RESULTS > Element Output > Frame Output) must be exported from SAP2000®.
The structure can be imported via StruBIM Uploader or directly into CYPE Connect and StruBIM Steel.
In StruBIM Uploader, by selecting the "XML file produced by SAP2000®" option, users access the file selection panel and select the BIMserver.center project, where the information will be uploaded.
After exporting to BIMserver.center, in CYPE Connect or StruBIM Steel, only the job needs to be created from that BIMserver.center project.
In CYPE Connect and StruBIM Steel, this can be imported directly via direct access to the StruBIM Uploader.
The bars and the forces in the bars by combination are imported.

Analysing connections with energy dissipation elements, for capacity design
In version 2025.c, CYPE Connect and StruBIM Steel include the necessary tools to carry out the analysis of connections with dissipative elements. These tools can be used to design connections for earthquake-resistant structures in which energy dissipation is foreseen through the formation of plastic hinges, either in one of the elements of the connection or in the bars linked to it.
In the "Analysis" tab, a tool has been added to select the dissipative elements, offering users the option to choose between sections and plates. The material properties of the dissipative elements are transformed in the load cases marked as "Capacity design", considering the effects of material overstrength.
For Eurocodes and similar standards, the program will request the overstrength coefficient of the material, ?ov, which amplifies both the yield strength and the ultimate strength of the dissipative elements. For American standards such as AISC360, NSR10, NTC-2023, among others, and other similar standards, the program will include in the material library the specific overstrength factors for each type of steel, Ry and Rt.
To analyse the connection for the over-resistance in dissipative elements, it is necessary to select not only the dissipative elements but also the "Capacity design" types of load cases in the list of load cases.
This new implementation allows users to design the connections so that the capacity of the connection is larger than that of the dissipative element while considering the over-resistance. In these cases, dissipative elements will experience large plastic deformations, which makes it difficult to converge the model, therefore, another relevant parameter in dissipative elements is the slope of the plastic span.
As detailed in the calculations manual, the constitutive law for plates and sections follows a bilinear model, where the slope of the plastic span is tan-¹(E/1000). For dissipative elements, in addition to incorporating the over-resistance coefficient as a multiplier of the yield stress, the slope of the plastic span is adjusted. In these elements, for a deformation of 5%, the stress will reach the elastic limit of the material, amplified by the over-resistance coefficient (?ov or Ry, depending on the applied standard) and by the resistance reserve coefficient due to strain hardening, which is equal to 1.1. This slope, greater than tan-¹(E/1000), contributes to improve the convergence of the analysis.
