Earthquake resistant design was introduced to Korea in 1988 for tall buildings, in 1992 for highway bridges and even earlier than that for nuclear power plants. The apartments designed by large unit housing planning was constructed by tunnel form method for the construction convenient in 1980. As a results, many structures without any seismic resistance capacity were built during the 80’s. In this paper, to improve the seismic capacity in wall-slab joint, experiments which improve and retrofit a seismic capacity by steel reinforcing, unequal angle bracing, carbon sheet attachment are carried out. These methods also are economic and simple in mitigating seismic hazard, improving earthquake-resistance performance, and reducing the risk level of building occupants. Consequently these methods were confirmed its effectiveness in improving the seismic performance were confirmed its effectiveness.
