The elegance and global character of modal analysis make it very attractive for adaptation to time-varying systems. Most of the concepts of modal analysis are well established in literature and widely understood for linear time-invariant systems. This paper discusses an adaptation of modal analysis

โฆ Synopsis
Abstract
A topological FEM method, in which a structure topological theory is applied to a FEM system, is presented in this paper. The method uses FEM solutions of a structure before any change to obtain the new response of changed structure, avoids reโcalculations from changing the FEM system, and reduces the amount of calculation work on a large scale. It is a new method for timeโvarying calculation in construction and technical analysis. Copyright ยฉ 2004 John Wiley & Sons, Ltd.
