This paper first presents general identification methods to model linear visco-elastic material dampers using generalized rheology models. Two types of generalized theology models are studied. One is the parallel combination of a generalized Maxwell model (GMM) and a generalized Voigt model (GVM) , and the other is the serial combination of them. Modeling for two types of vicso-elastic materials is performed to evaluate the modeling accuracy. Next, the error of the efficient numerical integration algorithm for the generalized rheology model is studied. The relation between the discrete time of the numerical integration and the error by the discretization is shown for two hybrid models. It is confirmed that accurate seismic response analyses with the hybrid models can be executed without excess discretization.
