Hello TomPaceHDR.

We already sent your comment to our programming team.
We will check your comments and we will come back to you with a detailed response as soon as possible.

It depends on the nonlinear rules that you have applied in your model, the deformation demand on these links and the way that a possible yield in the link affects the global structural response. One possible thing that crossed my mind is that the deformation-based performance criteria (when they emp...

Please download and install latest release of the program (Release-2 build-40). Usually similar problems are found fixed quickly. If however the problem remains, please report the problem at support@seismosoft.com with a detailed description of the steps that lead to the problem and a screenshot wit...

You can refer to all the posts in this forum regarding convergence issues. Another way is to change the parameters for the Element Iterative Strategy (Program Settings). However, note that the model is generally less stable with respect to the force-based, distributed plasticity models. Seismosoft S...

No, the bug is only in the pre-processor; it is just the message itself that should not pop up. Nothing related to the analysis. What you are experiencing is something else: the inherent numerical instability of the infrmDBPH model. Distributed plasticity models are much more stable numerically the ...

Indeed, this is a bug of the GUI that will be fixed in the upcoming Release-3 of v2024 of the program. The message is wrongly displayed, however this does not prevent the users from changing the infrmDBPH element class and assigning the automatic calculation of the section properties. Thanks for the...

I am not sure I understand with what you mean with the comparison between internal forces and height. I note that you can monitor the stresses of the monitoring points inside the section using the Stress Points facility (Pre-processor>Output module).

How do you get this message?
The automatic calculation of the hinge properties for the rectangular and square RC sections types is supported by the program, and we checked this feature and it seems to be working without problems.

The infrmFBPH model is a distributed plasticity model on the section level. The section if discretized to fibers and each fiber has its own material law (for steel, unconfined and confined concrete). Please refer to the manual and the help of the program.

According to all modern codes on Structural Assessment, the nonlinear analysis are conducted considering the mean, rather than the characteristic material values.
