Can you please send me the shear-axial interaction source code?
My email: arpitagi@buffalo.edu

I am working on a similar problem and was using hysteretic material for shear model of concrete. Do you have an answer to the question you posted that you can share?
Thanks in advance.

Hi Selimgunay,

Thank you for your answer. So can I just use nonlinear beamColumn element to specify force based formulation and keep the integrator as displacement control in the solver as used in example 4-Portal frame cyclic pushover?

Thanks

Hello, I am a new Opensees user and I am analyzing an RC Cantilever column using cyclic pushover but I want to do this using force based formulation. I am using the loadcontrol integrator for this and I get a convergence error. Can somebody please check my code and suggest ways to solve this issue. ...
