DISPLACEMENT CONTROL STRUCTURE FOR BRIDGE GIRDER
To provide a displacement control structure for a bridge girder capable of controlling the displacement amount of the bridge girder.SOLUTION: A displacement control structure for a bridge girder controls the displacement of a bridge girder 5 moving on a bridge pier during an earthquake. This displacement control structure is provided with a bearing part 10 which is arranged on the bridge pier 2 and supports the bridge girder 5, and a support surrounding structure 20 which is arranged on the bridge pier 2 and has a control surface 20A which extends toward a side edge 2a of the bridge pier 2 so as to be continuous from a support surface 10A of the bearing part 10, and the friction coefficient μ of the control surface 20A is set based on the weight m of the bridge girder 5 and the control surface length L of the support surrounding structure 20.SELECTED DRAWING: Figure 2
【課題】橋桁の変位量をコントロールすることができる橋桁の変位制御構造を提供する。【解決手段】橋桁の変位制御構造は、地震時に橋脚上で移動する橋桁５の変位を制御する。この変位制御構造は、橋脚２の上に配置された、橋桁５を支持する支承部１０と、橋脚２の上に配置された、支承部１０の支持面１０Ａから連続するように橋脚２の側縁２ａに向けて延在する制御面２０Ａが設けられた支承周囲構造体２０と、を備え、制御面２０Ａの摩擦係数μは、橋桁５の重量ｍと、支承周囲構造体２０の制御面長Ｌと、に基づいて、設定される。【選択図】図２
