BRIDGE BEARING USING THE SHAPE-MEMORY-ALLOY

摘要

A bridge bearing using shape memory alloy is provided to strengthen reconstitution function and vibration absorption function of structure. A bridge bearing using shape memory alloy comprises an top plate(10), a bottom plate(20), a supporting member(50) and a post(100). The top plate is mounted on the upper structure. The bottom plate is mounted on the lower structure. The supporting member is interposed between the top plate and bottom plate. The post is installed in post between the top plate and bottom plate in order to connect the top plate and bottom plate. The post is made of shape memory alloy. The post absorbs vibration energy while reducing the strength of horizontal earthquake. Plural shape memory alloys are installed the supporting device surrounding.
