Can anyone guide me about the warning message that is coming while I am running the model for Pushover analysis in SAP2000?
The Warning is"Analysis cannot find the solution at step no---for case:pushX
Subsequent result will not be available".
I tried to increase the null steps but then also I am facing this issue.
Thanks in advance.

There are three strategies in SAP2000 for unloading the hinge. Unload entire structure, even as the most robust is not always perfect. Try to change this to Local Redistribution, or Secant Stiffness. If your calculations prompt this error at the very beginning of the step, than something else is wrong with the model. Probably it is unstable or the units are wrong. Finally, check your law for nonlinear hinges, if you make the degradation branch more subtle (less steeper), will it help?
Kindly check, In which direction you are performing the Pushover analysis.
In Case you are doing it in the Y direction, you must change DOF in the displacement control tab from U1(default) to U2.
