If you select a Response Control scheme in the pushover Phases, what is really needed is the relative value of the different forces. These forces are proportional to the masses at each floor or location (and then they are multiplied according to the lateral forces pattern). Then the Loading Factor ...

Seismosoft''s Licensing section is closed today. The license will be probably sent to you tomorrow.

Since the concrete material in the actual section is one, the only differentiation between the core concrete and the cover concrete can be done through the confinement factors for the two regions. You could assign different materials through the jacketed rcjrs section, however I am not sure if this ...

Hello,
We have addressed the issue that you reported in your initial post and from SeismoBuild v2026, Release-2, build-25 onwards it is possible to specify the spectrum parameters for all the seismic hazard levels in ASCE 41. Thank you for your feedback!

Thank you for the feedback.
We already replied to your email. The reports comes out correctly in our system; possibly you will need to update SeismoBuild to the latest v2026 release.

This is divergence of the numerical solution. There are several reasons that could cause such problems.
In the SeismoStruct manual there is a dedicated section on the possible reasons for divergence and on how to overcome such difficulties. Furthermore, there are dozens of posts on convergence ...

Hello,

We checked again the report and it seems to be correct. Maybe we are missing something. Can you please be a bit more specific, specifying which are the exact values that do not seem to be correct? You could also send your project with more details at support@seismosoft.com

Note that in ...

We checked your model, and the first modes are the global ones, not local ones. There are 2-3 modes out of the first 10 that are vertical modes, but this is probably due to excessive vertical loading, rather than the modelling of the building.
If you feel that there is a problem with the creation ...

In SeismoStruct, you can use the crs composite section.
Regarding the interaction between steel and concrete, the program assumes that the two parts are fully connected.
