The seismic behavior of repaired/strengthened RC structures is difficult to analyze theoretically. However, this paper will show that analysis can be effectively done by using the so-called HYLSER (Hybrid Loading System of Earthquake Response) system. Three repairing/strengthening methods were considered: (1) the epoxy resin grouting method; (2) the reinforcing bars welding method; and (3) the steel plate covering method. Obtained stiffness deteriorating processes were verified to be almost the same as those of the original ones if adequate repairing methods were performed. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
