Abstract
Viscoelastic dampers (VED) have been used for seismic damage mitigation of structures lately. However, it is difficult to treat VED strictly in the dynamic response analysis because the dynamic mechanical characteristics of vicoelastic material are affected by temperature, frequency and strain. This paper presents the dynamic mechanical characteristics of styrene-olefin viscoelastic material STD1 and its analytical model. Temperature dependency of STD1 is smaller than that of GM1 which the writers developed before. So the effect of temperature on seismic response of VE-frame is investigated.
