PROBLEM TO BE SOLVED: To provide a reinforcing method for a wall structure by which buckling at end faces can be also prevented and further, an earthquake-resistance can be increased by adding a restrictive force against the end face of an existing wall structure. ;SOLUTION: A plurality of PC steel rods 3 inserted in a plurality of through holes in the thickness direction of an existing bridge pier 2 and steel segments 10 which are continuous column bodies having a circular arc-shaped section and are integrally provided with flanges 10b at both breadthwise ends of the circular arc-shaped sections, are provided in the reinforcing structure. A plurality of stages of the steel segments 10 are installed on the wall face of the bridge pier 2, and the inserted ends of the PC steel rods into the flanges are fixed with screws to fix respective steel segments 10 on the wall face. Then, concrete is placed in portions forming circular arc-shaped spaces between respective steel segments 10 and the wall face to integrally form it with the wall face of the bridge pier 2. Reinforcing bodies composed of concrete blocks 12 are installed at the end face in the thickness direction normal to the wall face of the bridge pier 2 and connected to the end part of the steel segments 10 through PC steel rods 14.;COPYRIGHT: (C)1999,JPO
