MULTISTORY EARTHQUAKE STRENGTHENING STRUCTURE

To effectively enhance the bearing force of an existing concrete column of an existing bridge construction provided with an earthquake-resistant element.SOLUTION: A multistory earthquake strengthening structure comprises: a plurality of existing constructions 30 which have a pair of existing concrete columns 32 and an existing concrete beam 34 constructed on the pair of existing concrete columns 32, respectively, and are successive in the vertical direction; a plurality of steel-made earthquake-resistant walls 40 which are provided for the plurality of existing constructions 30 respectively; a plurality of inside reinforcement steel plates 56 which are joined to inner side faces of the existing concrete columns 32 of the plurality of existing constructions 30 respectively; and tension materials 64 which cross the existing concrete beams 34 vertically and connect the upper and lower inside reinforcement steel plates 56 of the existing concrete beams 34 to each other.SELECTED DRAWING: Figure 1 【課題】耐震要素が設けられる既存架構において、既存コンクリート柱の引張耐力を効率的に高めることを目的とする。【解決手段】連層耐震補強構造は、一対の既存コンクリート柱３２と、一対の既存コンクリート柱３２に架設される既存コンクリート梁３４と、をそれぞれ有し、上下方向に連続する複数の既存架構３０と、複数の既存架構３０にそれぞれ設けられた複数の鋼製耐震壁４０と、複数の既存架構３０における既存コンクリート柱３２の内側面にそれぞれ接合される複数の内側補強鋼板５６と、既存コンクリート梁３４を上下方向に横切り、既存コンクリート梁３４の上下の内側補強鋼板５６同士を連結する引張材６４と、を備える。【選択図】図１
