Save Stiffness for Nonlinear Analysis in SAP2000
Save Stiffness for Nonlinear Analysis in SAP2000
(OP)
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.
