Hi,
I have a question about the capacity curve of a concrete frame building. It's a five-storey building and I modelled the beam and column using infrmFB with default value. The capacity curve I got from the pushover is not quite what I expected. What I got is the curve goes up, reaches the maximum ...

Hi,
There are two instances an analysis stops early, one is the convergence issue, the other is the structure cannot sustain more loads. Could you please clarify if convergence issue involves any structure capacity factor? In other words, if I get the convergence error, does it mean I can always ...

Does it mean I could control the effectiveness of the diaphragm action by modifying the shear property? Sorry I didn't find how to control the rigid diaphragm in the users manual. It seems it's an on-and-off thing. It can't be like 50% rigidity...

Thank you. What about the masonry wall section mws? I ran it with rigid diaphragm and did not see out-of-plane failure, and when I ran it without the diaphragm, I encountered convergence problem so badly that the program could not run.

Hi,
Is SeismoStruct able to model out-of-plane action? For example, my slab does not act as a rigid diaphragm so I expect panels to fall out-of-plane. Can SeismoStruct do that and how?
Thanks

Thank you! A further question is that which criteria does SeismStruct use when it stops an analysis and tells me the structure cannot sustain more loads? Does it use code-based criteria or performance-based? And does it use shear or flexural or compressive, etc.?

Hi,
Could someone please help me to understand what's the difference between the code-based checks and performance criteria? They look very similar to me but I notice they output different results...I read the manual but still not sure about it. Under performance criteria, I can see which formulae ...
