Seismic Performance Assessment of Laminated Rubber Bearing on Kadamtaly Flyove

Abstract

This study is dedicatecl towards conducting seismic performance assessment is Laminated Rubber Bearing ofkadamtaliJtyover. Theflyover isolated by elastomeric rubber bearing subjected to earthquake ground motion records. The isolation system considered in this study consists oJ'a elastomeric rubber bearing, which provides lateral flexibility while supplying high vertical load-carrying capacity. This stutdy describes a technique to "iti*ot, the seismic performance on laminated rubber bearing by calculating its strength and defotmationfrom a dynamic time-history- analysis using the soflware Seismostruct. A 3-D model of Kadamtoli Flyover has been constructed and the strength and deformation ofrubber bearing has beenfound. The analytical results show that the seismic responses of rubber bearing are significantty alfected by the characteristics of the earthquake ground motion records.
