Description

The first part of this paper outlines a proper and efficient method to quantify both temperature- and frequency-dependent properties of a viscoelastic damper (VED) by random loading test, and shows that a generalized Maxwell model can be used to exactly simulate those properties of the VED. The second part deals with an analysis method for structures with VEDs simulated by generalized Maxwell models. The method is quite efficient because it can eliminate degrees of freedom of the nodes between springs and dashpots which constitute generalized Maxwell models. The validity and efficiency of the algorithm are shown through an appropriate sample analysis.
