EVALUATION ON SEISMIC RESPONSE CONSIDERING CHARACTERISTICS OF HIGH DAMPING RUBBER BEARING

Abstract

 Experienced shear strain dependency of high damping rubber bearing which is induced by Mullins effect of rubber is one of influencial dependency to seismic responce. So the effect of experienced shear strain dependency on seismic responce of isolation structure should be evaluated.From past studies, we indicated that loading history must be taken into account. And then seismic responce analysis are performed by bi-linear double target model which is able to take into account the experienced shear strain dependency. From seismic responce analysis, the effects of experienced sherar strain dependency on seismic responce are evaluated.
