can I get stiffness and mass matrix from SAP2000?
can I get stiffness and mass matrix from SAP2000?
(OP)
I built a model for a highway bridge in SAP2000.
Can I get out stiffness and mass matrix from SAP2000? I want to input the matrix into a FEM problem to run some special cases.
Thank you for your input.

I have not tried this, but this option seems to be the one.
