Modelling shear wall with moment resisting frames in SAP2000 using wide column method

[phildude2013]

Hello. I'm new here. I'm doing research using nonlinear static analysis, of 2D shear walls with moment resisting frames in SAP 2000. I'm reading a lot of literature about my methodology, which is to model them like wide columns with rigid beams.

What are the supposed nonlinear hinges that I should insert at the models? According to this study, shear walls can be modeled using a combination of "rigid" beams and mid-piers. The dimension of "rigid" beams are the shear wall's thickness as its thickness, and one-story height dimension as depth. The dimension of mid-piers are the shear wall's dimension too, so I assume thickness of the wall is the same as the mid-pier's, and its width is the same as the span width.

I have trouble adding nonlinear hinges. I tried adding M3 hinge at the "rigid" beams and model it like a beam, and P-M3 hinges were added at the mid-pier and modeled it like a column. However, it gives bad pushover curves (like it doesn't show hinge drops) something like that.

Anybody here knows how to do shear wall modelling using this method? I have a trouble doing this, I tried to contact the authors, however, they're not responding for like two weeks now.

I think that you do not need to add hinges to the rigid elements.

Dear phildude2013,
Did you get the answer for the question? If yes, pls do share the here. I wanted to know how shear walls can be modeled as equivalent beam and incorporate non-linearity in same for carrying out pushover analysis in SAP2000? If you have any relevant document pls do share that too.
