This paper aims at presenting a new method to simulate the dynamic behaviors of Visco-Elastic Dampers (VEDs). In the method, a generalized rheology model, i.e., a parallel combination of a general Maxwell model and a general Voigt model, is used. The model can be used over wide range of frequencies without changing its parameters. It is shown that although the model holds many springs and dashpots, their parameters can be easily identified by making use of the extended Kalman Filter. An efficient algorism to perform dynamic response of structural systems including VEDs is also presented. Usefulness of the method is confirmed in two ways; one by examining the accuracy in describing mechanical properties of several VEDs; and the other by studying the expected time to calculate dynamic response of structural systems with VEDs.
