In this paper, a method to simulate the dynamic behaviors of Visco-Elastic Dampers(VEDs) is analytically studied. A generalized rheology model, which is a parallel combination of a general Maxwell model and a general Voigt model, is used as a model of VEDs. The model can simulate complicated behaviors of VEDs over wide range of frequencies without changing its parameters. Because the model has a lot of springs and dashpots, it is anticipated to requirea lot of calculation time to execute a dynamic response analysis of the system with VEDs. To avoid this, an efficient algorithm to perform dynamic response is proposed. Applicability of the model to not only a linear damper but also a non-linear damper was examined. It was found that the method can simulate the behaviors of VEDs exactly without much increase of the calculation time to carry out dynamic response analyses.
