PROBLEM TO BE SOLVED: To provide a reinforcing structure which can obtain sufficient earthquake resistance exerted in a direction orthogonal to the bridge axis of a bridge, and to reduce construction cost and a construction period by dispensing with the large-scale seismic reinforcement of a foundation. SOLUTION: In this reinforcing structure of the bridge, reinforcing cables for connecting a top of a bridge pier and a fixed structure installed in the ground are installed on both sides of the bridge pier with respect to the direction of a bridge axis, respectively. Preferably, a foundation pile, an earth anchor or a counterweight is used as the fixed structure, and the bridge is applied to a pedestrian bridge. COPYRIGHT: (C)2008,JPO&INPIT
