Abstract

In this paper, the static substructure method based on the Ritz vector direct superposition method is suggested for analysing the dynamic response of structures. The advantage of this algorithm is that the computer cost can be reduced and the static analysis and the dynamic analysis of large structures can be simplified by using the identical static substructure method.
