It is necessary to consider the frequency dependent behavior of viscoelastic material in order to simulate seismic behavior of structures with viscoelastic dampers. Three dynamic mechanical models for viscoelastic material, the spring-dashpot model, the fractional derivative model and the fading memory model are examined in frequency and time domains. A generalized fractional derivative model is proposed to consider frequency dependent for wide frequency region. The spring-dashpot model and the fractional derivative model are expressed by the fading memory model with an adequate memory function. Load-deformation relations of calculated results using three models were in agreement with experimental value respectively. Three models explain well frequency dependent characteristic of viscoelastic material.
