P-Delta analysis lost some loads

[jowook]

Hi everyone,
I've got different total reactions from two load cases. Those two load cases are both are nonlinear but one has P-delta and the other does not have. Non p-delta total reaction number is doubled. It seems p-delta analysis lost some loads. I didn't get any warnings or errors by Advanced solver. How can I detect errors of my model or what elese can I try on the model?

Thanks in advance.

Hello, everyone
I found out why by myself. On nonlinear parameter settings, I switched from off for "Use Event to event stepping" to on, and the problem solved. It seems that SAP2000 solver stopped and gave up iteration without turning on this parameter during the solving the nonlinear case.
I thought this parameter for unloading joints, frames and whatever such as a plastic hinge. Thanks for reading

thanks for sharing the solution with others ....good manners
