The present invention relates to a seismic reinforcement structure capable of increasing a seismic performance of masonry infill wall formed in a reinforced concrete structure. More specifically, reinforcing plates with holes are attached to both surfaces of a masonry infill wall, so both reinforcing plates are connected and fixed to each other. Each of upper and lower ends of the reinforcing plate is rigidly attached to a beam of the reinforced concrete structure through a bracket. Therefore, the seismic reinforcement structure can be constrained on a non-load-bearing wall, such as a masonry infill wall, forward and backward and in a transverse direction and can increase ductility and stiffness of the masonry infill wall by variously changing the size, shape, and arrangement of the hole, thereby remarkably increasing its seismic performance. Moreover, the seismic reinforcement structure can ensure economic and construction benefits by easily and rigidly forming fastening between the bored steel plate and the existing concrete beam, and can increase ductility and release stress concentrated on a foundation part by preventing excessive stiffness reinforcement using the bored steel plate. |
