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: A vibration control mechanism B, in which an inertia mass damper 4 and a spring member 5 are connected together in series, is installed in the state of being connected to upper and lower structures 2 and 3 in parallel with a bearing 6. The upper and lower structures 2 and 3 are relatively displaced, and a weight of the inertia mass damper 4 is rotated to exert an inertia mass effect. A frequency of the vibration control mechanism B, which is determined by the inertia mass damper 4 and the spring member 5, is synchronized with a predominant frequency of a bridge 1 by the spring member 5.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】慣性質量ダンパー４とばね部材５を直列に連結してなる制振機構Ｂを、支承６と並列に上部構造２と下部構造３に連結して設置し、上部構造２と下部構造３が相対的に変位するとともに慣性質量ダンパー４の錘が回転して慣性質量効果が発揮され、ばね部材５によって、慣性質量ダンパー４とばね部材５により定まる制振機構Ｂの振動数を橋梁１の卓越する振動数に同調させるように構成する。【選択図】図１
