Response of Seismically Detailed Beam Column Joints Repaired with CFRP Under Cyclic Loading

Present investigation consists in casting and testing six seismically detailed beam column reinforced concrete joints. All specimens were subjected to quasi-static monotonic loading. These damaged specimens were refurbished with two different configurations of carbon fiber-reinforced polymer laminates. Repaired specimens were again subjected to quasi-static monotonic loading. Results of investigation revealed that ultimate strength of configurations 1 and 2 was increased by 8.6, 6.7 % and ultimate deflection was increased by 54.6, 51.2 %, respectively. However, ductility factor, stiffness and ductility of repaired specimens were decreased by 24.8, 25.6; 60.6, 51.7; 49, 48 %, respectively.
