The aim of this study is to investigate the influence of CFRP reinforcement on the seismic performance of damaged reinforced concrete columns. Experimental tests were conducted under two conditions: before and after reinforcement, with seismic simulation loads. The failure mode, bearing capacity, ductility and other indicators of the columns before and after reinforcement were compared and analyzed. The experimental results showed that the seismic performance of damaged reinforced concrete columns was significantly improved after CFRP reinforcement, which can effectively improve the safety performance of the damaged reinforced concrete columns.【关键词】CFRP 加固；地震损伤；钢筋混凝土柱；抗震性能；试验讨论
