【 摘 要 】

This study examines the seismic performance of four non-seismically designed reinforced concrete structures with core walls and proposes proper rehabilitation methods. The structures were selected based on the height of the structures, occupancy levels and floor plans. The seismic assessment results were compared based on the performance of the structures before rehabilitation and after rehabilitation. The results indicate that most of the structures are unsatisfactory in terms of their failure to reach a level of life safety. Three types of rehabilitation methods, i.e., reinforcement walls, braces and columns, were applied to assess the seismic performance of the four case studies. The two-phase seismic assessments of the rehabilitated structures were conducted according to current provisions used in Korea.
