Abstract: Bridges are essential links for transportation lifeline system. They should remain safe during and after devastating earthquakes. From earthquake point of view, bearing is a very critical part of the bridge, because the inertia force from deck is transferred to sub structure through bearings. Conventional bearings ( Rocker and Roller ) transfer most of the inertia forces-from deck to the pier. So at higher ground acceleration the structure goes in the inelastic range and thus plastic deformation occurs. Base isolation is a strategy for decoupling the substructure from inertia forces •in the deck by providing flexibility between deck and pier. A base isolation system must possess flexibility and energy absorption qualities. A lead-rubber bearing offers a good means of providing base isolation because of cheapness, high vertical stiffness, horizontal flexibility and energy absorption. At low level of ground acceleration, the lead-rubber bearing behaves as conventional bearing but at higher levels it goes in inelastic range and provides. isolation. However the rest of the structure remains elastic.
