Lead Rubber Bridge Bearings is installed as a Damping Equipment under building structures so as to control the tremor of structure against the loads of earthquake. This bearing is mainly applicable to small & medium bridge and not suitable for large bridge because of installation with a limit of dimensional height and volume according to the displacement moved from earthquake or impact load so it's restricted on the scale of bridge.
Base Isolation System, which is a branch of manual technique to reduce the tremor of structure, is widely applied to the large sized structures such as road bridges, rail bridges and nuclear power station to minimize damages from dynamic loads like earthquake. Also because it has the economic and functional efficiency with comparative perfection, the Base Isolation System is studied and used in the world, especially in USA and Japan. So many bridges and buildings to which the Base Isolation System is applied are constructed in many countries including USA and Japan all over the world, and the constructed structures showed so high the function of isolation from earthquake that they proved the safety when arising the earthquake in practice.
Also the installation of Earthquake Absorbing Bearing is likely to be required in the world in order to get the efficiency of seismic force damping function and of constructive cost down for the lower parts of structures.
