Abstract - Base isolation systems have become a significant
element to enhance reliability during an earthquake. In recent years base isolation has become an increasingly applied structural design technique for buildings and bridges in highly seismic areas. The commonly used isolation system are Lead Rubber Bearing, Laminated Rubber Bearing, Friction Pendulum, trench Method, Pile Method and Damper. In this research paper there is detail about all five isolation systems and comparison between Friction Pendulum and Laminated Rubber Bearing for a 10 storey building and conclusion about which is the best isolation system for the two.
