Abstract
Abstract A continuous bridge, horizontally curved in plan and isolated with Lead Rubber Bearing (LRB), has been investigated under seismic loading conditions. Two recorded ground motions, representative of historical earthquakes along with far-field (Imperial Valley) and forward directivity effect (Turkey), respectively, have been considered. The bi-directional effect of the bearings considering interaction behavior of bearing and pier has been determined. Modeling and analysis of the bridge have been done by finite element approach. It has been noticed that there is a significant influence of bi-directional loading and the same is found to be maximum in Turkey ground motion which might be due to forward directivity effect.
