Stiffness and Mass matrix plays a very important role in structural static and dynamic analysis problem. The entire analysis problem is based on these two matrices. But Sap 2000 does not provide these matrices directly, thus some indirect method has to be used to get these matrices and have some better understanding. Accordingly, this program has been developed to extract stiffness and mass matrices for your particular problem case from Sap 2000.
Instructions about using this program have been described in the m file.
