EARTHQUAKE RESISTANCE REINFORCING STRUCTURE FOR BRIDGE
To provide an earthquake resistance reinforcing structure for a bridge capable of improving earthquake resistance and being easy to construct.SOLUTION: An earthquake resistance reinforcing structure 10 for a bridge 1 having a bridge girder 2 extending in a bridge axis direction X and a locking bridge pier 3 supporting the bridge girder 2, includes: a damper 11, connecting an intermediate part of the bridge girder 2 in the bridge axis direction X and a foundation G, which absorbs earthquake kinetic energy in a bridge axis perpendicular direction Y of the bridge girder 2 with respect to the foundation G.SELECTED DRAWING: Figure 2
【課題】耐震性を向上させることができ、かつ施工が容易である橋梁の耐震補強構造を提供する。【解決手段】橋軸方向Ｘに延びる橋桁２と、橋桁２を支持するロッキング橋脚３とを有する橋梁１の耐震補強構造１０であって、橋桁２の橋軸方向Ｘの中間部と地盤Ｇとを接続し、地盤Ｇに対する橋桁２の橋軸直角方向Ｙの地震動エネルギーを吸収するダンパー１１を備えることを特徴とする。【選択図】図２
