Hi,
To validate my plate section material. I used the shell element to analyze a shear wall structure subjected to a in-plane load. The numerical result is compared with that calculated by plane stress Quad element. A well agreement can be found for linear case. For nonlinear case, the Quad element works well. However, I allways get a wrong result with the shell element. I can't get the desending branch. Why? Is the shell element suitable for my case? Thanks.

Re: Problem on Opensees shell element
Shell element is more appropriate for out of plane loads. What section did you assign to shell element?

Thank you, vesna.
I assign a RC multilayered shell section coded by myself.
Yes, as you said, I can get a good result for the out-of-plane case.
However, for shear wall structures, the in-plane load is more important.
Is any other shell element available in Opensees? or will be available?

Re: Problem on Opensees shell element
as of now we are not developing one and we do not know if anyone else is working on this.
