Appendix A: The Stiffness Matrix
Fig. A.8 Assembly of the stiffness matrix
The overall mass matrix, overall damping matrix and the overall exciting force
matrix can be similarly formed from the respective element matrices.
There are various ways, by which levels in the displacements are put. In the scheme
that has been discussed, the active degrees of freedom are labelled (their total is NP)
first, and then, the restraints are labelled. The first set of equations NP is operated
upon, for obtaining the necessary solution.
