Dear All,
What stress resultant plasticity model is used in OpenSEES?

Thanks

Thanks Prof., I went through the post, it is about a bidirectional section. I want to know what model is used to determine stress resultant yield surface for a normal (unidirectional) fiber section in opensees. Can you please provide some information about that.

Thanks
Abira

I'm not sure about your question then. Fiber sections determine the stress resultant interaction automatically.
