can I get stiffness and mass matrix from SAP2000? 2

myabc · Dec 1, 2006

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.

The experts in my office tell me they don't believe it can be done. You can export shears, moments, deflections, etc. from SAP, but not the actual stiffness matrix. Let us know if you find out differently.

yes, please to go to-
Analyze>Set Analysis Options...> Solver Options > Output Mass and Stiffness Text Files.
I have not tried this, but this option seems to be the one.
