Nonlinier Time History Analysis of Anti Seismic Device on Highway Bridges
Keywords:Lead Rubber Bearing, Time history, Base shear, Displacement, Acceleration
There are many earthquake suppression technologies offered by experts, one of them is the use of Lead Rubber Bearing (LRB) in civil buildings. LRB works by reducing the dynamic load acting on a bridge caused by seismic loads. It diverts the load that works through the dynamic system by maintaining a balance between the force and displacement that occurs. The purpose of this study is to find out how much influence are the use of LRB on the reduction of seismic loads received by a flyover. This study compares the structure of the highway bridge using LRB to those non- LRB, where the results show that the use of LRB can reduce the base shear occurs in bridge piers and is able to increase energy attenuation, but causes additional displacement and acceleration.
