i am working on a project using sap2000 and i need to take stiffness and mass matrices and pass them to matlab
i run run your model you take these matrices in a txt form.all i want to know is if there is another way to extract them
Good question.. Please share me the best answer might you trust...
Regards…
In SAP2000, you should go to
- Analyze
- Analysis options
- Solver options, then select advance Solver, and Select Analysis case name (e.g. DEAD).
Then a file with extension .TXK should be created in the folder of the project. That is half of the stiffness matrix.

First, extract .TXE, .TXK, .TXM files as introduced by the clip on youtube.

Second, copy each information to the excel file as the one attached herein (TanNguyen_KT.xlsx).
Third, open and run the matlab file attached herein (TanNguyen_KT.m).
Please let me know if there is any problem. Thank you.
***NOTE:
The code is for 2 dimensional systems in SAP2000.
The code is for Matlab2020a.
Good luck,
