REINFORCEMENT STRUCTURE AND METHOD FOR BRIDGE PIER CROSSING SECTION
To provide a reinforcement structure and method for a bridge pier crossing section capable of performing reinforcement at a low cost in a short time by attaching a reinforcement member having a simple structure and being easy to attach, and capable of controlling a damaged part and a breakage form at the time of an earthquake.SOLUTION: A reinforcement structure for reinforcing a bridge pier crossing section comprising a bridge pier 11, a girder end of a first girder placed on the top end of the bridge pier 11, a base part 15 formed at the top end of the bridge pier 11, and a girder end of a second girder placed on the top end of the base part 15, includes a rod member 21 that penetrates the base part 15 in the longitudinal direction. One end of the rod member 21 is engaged with the surface of the base part 15 opposite to the girder end of the first girder, and the other end is engaged with a reaction force receiving member located on the girder end of the first girder.SELECTED DRAWING: Figure 3
【課題】構成が簡素で取付け作業が容易な補強材を取付けることによって、低コストで短期間に補強を行うことができ、かつ、地震時の損傷箇所と破壊形態とを制御することができる橋脚掛け違い部補強構造及び方法を提供する。【解決手段】橋脚１１と、該橋脚１１の天端に載置される第１の桁の桁端と、前記橋脚１１の天端に形成された台部１５と、該台部１５の天端に載置される第２の桁の桁端とを含む橋脚掛け違い部を補強する補強構造であって、前記台部１５を前後方向に貫通する棒部材２１を備え、該棒部材２１は、一端が前記台部１５における第１の桁の桁端と反対側の面に係合され、他端が前記第１の桁の桁端側に位置する反力受部材に係合される。【選択図】図３
