This study was conducted to examine experimentally the seismic performance of non-ductile reinforced concrete (RC) frames retrofitted with precast(PC) engineered cementitious composite (ECC) wall panels. The seismic performance was investigated through cyclic load tests on RC frame with different aspect ratio (h_w/l_w = 2 and 3) and installation position (center and both side of RC frame) of the PC ECC wall panels. Test results indicated that the seismic strengthening method using PC ECC wall panels is effective to improve significantly the strength, stiffness and energy dissipation capacity of non-ductile RC frame. Based on test results, it can be recommended to install PC ECC wall panel at the center of RC frame for improving the strength and to install slender wall panels at both side of RC frame for increasing ductility.
