PERFORMANCE REINFORCEMENT STRUCTURE FOR RUBBER BEARING DEVICE OR BASE ISOLATION BEARING DEVICE, USING STRUCTURE VIBRATION DAMPER
PROBLEM TO BE SOLVED: To provide a performance reinforcement structure for a rubber bearing device or base isolation bearing device, using a structure vibration damper that enables easy installation work and makes it possible to reinforce performance of the rubber bearing device or base isolation bearing device at a low cost.SOLUTION: A structure vibration damper comprises: a cylindrical member that is fixed on one of a lower structure and an upper structure; and a rod member that is fixed on the other structure and extends from an aperture of the cylindrical member to the inside, and is disposed so as to be displaced relatively to the cylindrical member. On the inner wall of the cylindrical member is fixed the outer periphery part of at least one of an elasto-plastic rubber and a seismic energy absorbing material made from lead or tin that include a hole into which the rod member is inserted and have a ring shape; relative displacement between the cylindrical member and the rod member at the time of an earthquake is made to act on the seismic energy absorbing material to absorb seismic energy. Performance is reinforced by using the structure vibration damper together with a rubber bearing device or base isolation bearing device.SELECTED DRAWING: Figure 1
【課題】設置作業が容易で、低価格でゴム支承装置又は免震支承装置の性能を増強することが可能な構造物用制振ダンパーを用いたゴム支承装置又は免震支承装置の性能増強構造を提供することを目的とする。【解決手段】下部構造又は上部構造の一方に固定される筒状部材と、他方の構造に固定され前記筒状部材の開口から内部に伸び、前記筒状部材との間で相対変位可能に配置されロッド部材と、を備え、前記筒状部材の内壁に前記ロッド部材を挿通する穴を形成したリング状の弾塑性ゴム、鉛又は錫からなる地震エネルギー吸収材の内の少なくとも１つの外周部を固定し、前記筒状部材と前記ロッド部材の地震時の相対変位を前記地震エネルギー吸収材に作用させて地震エネルギーを吸収する構造物用制振ダンパーをゴム支承装置又は免震支承装置と併用し性能を増強することを特徴とする。【選択図】 図１
