SEISMIC STRENGTHENING STRUCTURE OF BRIDGE
To provide an epoch-making seismic strengthening structure of bridge that allows easy arrangement of seismic strips and easy fixing of the seismic strips with a high degree of freedom.SOLUTION: A seismic strengthening structure of bridge comprises: a first seismic strip 3 that attaches a tip to a superstructure 1 erected in a span L of a single span bridge or the span of one end in the bridge axial direction of a multispan bridge; and a second seismic strip 4 that attaches the tip to the superstructure erected in the span of the single span bridge or in the span of the other end in the bridge axial direction of the multispan bridge. The first seismic strip is stretched diagonally downward from an attached tip 3a toward one end side of the bridge in the bridge axial direction. A rear end 3b of the first seismic strip is fixed to a ground G while the second seismic strip is stretched diagonally downward from the attached tip 4a toward the other end in the bridge axial direction. The rear end 4b of the second seismic strip is fixed to the ground.SELECTED DRAWING: Figure 1
【課題】耐震用条材の配設作業を簡便に行うことができると共に、当該耐震用条材の定着作業も簡便且つ自由度の高いものとすることができる画期的な橋梁の耐震補強構造を提供する。【解決手段】橋梁の耐震補強構造は、単径間橋の径間Ｌ又は複径間橋の橋軸方向一端の径間において当該径間に架設された上部工１に先端部を取り付ける第一耐震用条材３と、上記単径間橋の径間又は上記複径間橋の橋軸方向他端の径間において当該径間に架設された上部工に先端部を取り付ける第二耐震用条材４を備え、上記第一耐震用条材を上記取り付けられた先端部３ａから橋梁の橋軸方向の一端側に向けて斜め下方に張り渡し、該第一耐震用条材の後端部３ｂを地盤Ｇに定着すると共に、上記第二耐震用条材を上記取り付けられた先端部４ａから橋梁の橋軸方向の他端側に向けて斜め下方に張り渡し、該第二耐震用条材の後端部４ｂを地盤に定着することを特徴とする。【選択図】図１
