The structure which was designed until then had no resistance to earthquake, since enforcement ordinance for seismic design was established in 1988. Most of mid or low story building have no resistance to earthquake, though it is the structure which was designed since then. Prior to this experiment, the experiment, which was repair and retrofit method for seismic performance progress of the reinforcement structure which was not designed to be protected from an earthquake, had been performed and obtained good results. The aim of study is that repair the structure and evaluate seismic performance of the repaired structure in the case of the structure damaged by earthquake.
