Save Stiffness for Nonlinear Analysis in SAP2000

[JeenaSAP2000]

Hi all,

I am running a Nonlinear analysis with P-Delta effects. Can I save the total stiffness matrix of the system (elastic + geometric) for a dead load analysis. I followed the steps in the following thread, but this could save only the elastic stiffness matrix from a linear analysis and not from a nonlinear analysis.

Can someone suggest any other method to save the stiffness matrix including the geometric stiffness part ?

Thanks in advance.
