hy
I want to model steel plate shear wall with stripe element. Do you have an idea to doing this?

I cannot find any example to model this kind of problem.
if you have any example or refer Please help me.

guys please help me
how do i can modeling steel wall in opensees

[ismailqeshta]

I wish if I could help you, but I have never come across such a problem. You may post your question in researchgate.net, so you will have more people to view your modelling problem. Good luck.

Hi did you find any solution for your problem?
I am looking for some information about SPSW too in 3D. I would be helpful to know if you found something already.
Thanks in advance
