VIBRATION CONTROL STRUCTURE FOR BRIDGE, AND SETTING METHOD FOR THE SAME
PROBLEM TO BE SOLVED: To provide a vibration control structure for a bridge, which can reliably and effectively improve earthquake performance of the bridge by vibration control, and a setting method for the same.SOLUTION: Vibration control dampers B1 and B2 are installed in such a manner as to be arranged in parallel with a bearing 4 by having the side of one end connected to an upper structure 2 and having the side of the other end connected to a lower structure 3. In addition, a viscous-damping damper and an inertia mass damper are concurrently used as the vibration control dampers B1 and B2.SELECTED DRAWING: Figure 1
【課題】制振によって確実且つ効果的に橋梁の耐震性能を向上させることを可能にする橋梁の制振構造及び橋梁の制振構造の設定方法を提供する。【解決手段】一端側を上部構造２に接続し、他端側を下部構造３に接続して、支承４と並列配置されるように制振ダンパーＢ１、Ｂ２を設置して構成する。また、制振ダンパーＢ１、Ｂ２として粘性減衰系ダンパーと慣性質量ダンパーを併用する。【選択図】図１
