Dear STKO Team,
I am facing trouble in running my high rise building model due to non-convergence after some time steps. Can you help me with the identification of the problem.
This is the warning I get.

Dear STKO Team,
I have already replaced those files. However the same error is occuring. Also this error is occuring when I run the model.

Hi,
I am working on a high rise building. I get a wrong stress strain response for confined concrete once I defined the RectangularFiberSection for the column. Can you help me with this issue? I have attached the file.
Thank you in advance!

Thank you so much for your support!

Dear STKO team,
I used concrete01 and the error is generated when I assign the concrete material to the section. This is the file.

Dear STKO team,
Whenever I assign concrete material for concrete cover in RectangularFiberSections section i get an error as
Error:
