VIBRATION CONTROL REINFORCING STRUCTURE OF BRIDGE
PROBLEM TO BE SOLVED: To provide a vibration control reinforcing structure of a bridge which can absorb earthquake energy with respect to even an earthquake force acting in an arbitrary direction.SOLUTION: A vibration control reinforcing structure 100 of a bridge is provided in which a first vibration control damper 1a and a second vibration control damper 10b are arranged between a bridge pier 2 which forms a bridge 1 and a superstructure 4, one end part of the first vibration control damper 10a is rotatably arranged at the bridge pier 2 in a position shifted to a bridge width center, the other end part of the first vibration control damper 10a is rotatably arranged at the superstructure 4 in a position shifted to one side face 4a of the superstructure 4, one end part of the second vibration control damper 10b is rotatably arranged at the bridge pier 2 in a position shifted to the bridge width center, and the other end part of the second vibration control damper 1b is rotatably arranged at the superstructure 4 in a position shifted to the other side face 4b of the superstructure 4.
【課題】任意の方向に作用する地震力に対しても、地震エネルギーを吸収することができる橋梁の制振補強構造を提供する。【解決手段】橋梁の制振補強構造１００は、橋梁１を形成する橋脚２と上部工４との間に第１制振ダンパー１０ａおよび第２制振ダンパー１０ｂが設置され、第１制振ダンパー１０ａの一方の端部は橋幅中央寄りの位置で橋脚２に回転自在に設置され、第１制振ダンパー１０ａの他方端部は上部工４の一方の側面４ａ寄りの位置で上部工４に回転自在に設置され、第２制振ダンパー１０ｂの一方の端部は橋幅中央寄りの位置で橋脚２に回転自在に設置され、第２制振ダンパー１０ｂの他方端部は上部工４の他方の側面４ｂ寄りの位置で上部工４に回転自在に設置されている。【選択図】図１
