modeling diagonal CBF brace

[Matti]

Hi everyone

I am trying to model a one-story steel frame with diagonal CBF bracing. I want to simulate a hinge located in the middle of the brace, according to the multi-linear backbone curve introduced in the ASCE 41-13 with corresponding parameters stated in Table 9-7.

How can I model this behavior in OpenSees?

Thanks
