Abstract
Viscoelastic damper, Vibration control structure, Earthquake response analysis, Nonlinear four element model, Voigt model Viscoclastic dampers (VED) have been used for seismic damage mitigation of building structures. However, it is difficult to treat VED strictly in the earthquake response analysis because the dynamic mechanical characteristics of such materials are affected by temperature, frequency and strain. This paper presents a simplified analytical model for earthquake response analysis of buildings using styrene-olefin viscoelastic dampers. It is concluded that the simplified analytical model could estimate the earthquake responses of structures using styrene-olefin viscoelastic dampers and the model is effective for design of vibration control structures.
