Hello i am trying to do a nonlinear analysis on the model shown above

But I'm always getting the same model that is

MAXMUM NUMBER OF NULL STEPS REACHED FOR CASE: PO X SUBSEQUENT RESULTS WILL NOT BE AVAILABLE (1000 null step)

and used check the model option and there was nothing wrong

I turned the p-delta option off and also it didn't help

Any idea what could be causing that to happen?

I'm designing a coupling beam (manually) for the first time as a student

And I'm designing it according to Aci318-19 (18.10.7)

And i noticed that there is no requirement that includes moment forces

So do we neglect the moment force when we design a coupling beam?

In my case my beam L/h ratio is 1
