Seismic Performance Assessment of Laminated Rubber Bearing on Kadamtaly Flyover

Abstract

This study is dedicated towards conducting seismic performance assessment is Laminated Rubber Bearing of kadamtali flyover. The flyover isolated by elastomeric rubber bearing subjected to earthquake ground motion records. The isolation system considered in this study consists of a elastomeric rubber bearing, which provides lateral flexibility while supplying high vertical load-carrying capacity. This study describes a technique to estimate the seismic performance on laminated rubber bearing by calculating its strength and deformation from a dynamic time-history analysis using the software Seismostruct. A 3-D model of Kadamtoli Flyover has been constructed and the strength and deformation of rubber bearing has been found. The analytical results show that the seismic responses of rubber bearing are significantly affected by the characteristics of the earthquake ground motion records.
