This paper presents extended generalized Maxwell models for two types of nonlinear viscoelastic dampers. The models consist of a generalized Maxwell model to take into account the frequency-dependent mechanical properties of the damper and nonlinear hysteretic springs to simulate the softening and hardening type deflection-dependent nonlinear behaviors. For each type of the damper, mechanical properties are quantified based on a series of cyclic loading tests and then an extended generalized Maxwell model is constructed.Availability of the model is confirmed by comparing the experimental and analytical hysteretic loops, as well as time histories of hysteretic energy of the damper to which a random deflection simulating seismic effect on building structure is applied.
