ASEISMATIC REINFORCEMENT METHOD AND ASEISMATIC REINFORCEMENT STRUCTURE
To provide an aseismatic reinforcement technology which facilitates the installation even when there is any factor typical to the existing bridge.SOLUTION: Four bridge girders G1 to G4 are integrated together into one connection girder GX. The constraint in the horizontal direction is reduced with respect to supports B2, B3, B4, B5, B6, and B7 installed in bridge piers P1 to P3. For bridge abutment A1, A2 other than the bridge piers P1 to P3 (the bridge piers which support the supports B2, B3, B4, B5, B6, and B7 to be reduced the constraint in the horizontal direction), the aseismatic reinforcement is applied. More specifically, the aseismatic reinforcement is not given to the bridge piers P1 to P3 for which the construction condition is severe, and the aseismatic reinforcement is given to the bridge abutment A1, A2 for which the construction condition is mild.SELECTED DRAWING: Figure 2
【課題】既設橋りょう特有の要因がある場合でも、容易に施工可能な耐震補強技術を提供する。【解決手段】４つの橋桁Ｇ１〜Ｇ４を一体とし、１つの連結桁ＧＸとする。橋脚Ｐ１〜Ｐ３に設置される支承Ｂ２，Ｂ３，Ｂ４，Ｂ５，Ｂ６，Ｂ７について水平方向の拘束を低減する。橋脚Ｐ１〜Ｐ３（水平方向拘束低減対象の支承Ｂ２，Ｂ３，Ｂ４，Ｂ５，Ｂ６，Ｂ７を支持する橋脚）以外の橋台Ａ１，Ａ２において、耐震補強をおこなう。すなわち、施工条件が厳しい橋脚Ｐ１〜Ｐ３においては、耐震補強を行わず、施工条件の制約が緩い橋台Ａ１，Ａ２にて耐震補強をおこなう。【選択図】図２
