1)Lead Rubber Bearings for Bridges (Seismic Isolator)
Seismic Isolator is installed as a Damping Equipment under building structures so as to control the tremor of structure against the loads of earthquake.
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 co***rative 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 thefunction 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.
2) Special Features of Lead Rubber Bearings for Bridges
* Strong Points
As it is made of vulcanized rubber layers, reinforced thin steel plates laid alternatively in the elastomeric pad, and one or several lead cores inserted through the elastomeric pad and top & bottom steel plate, Earthquake Absorbing Lead Rubber Bearing not only controls the volume of displacement with resisting the first horizontal loads, but also prevents the bridge from falling down with absorbing the second horizontal loads at the time of earthquake.
* Property of Lead as a Suitable Material for Earthquake Absorbing Work
Lead is a suitable material used for earthquake absorbing work owing to the followings; first, as lead has a high malleability, it is able to be transformed from small to large range at a low temperature, second, the m |
