hear failures in the beam-column joint area and it may resulted in large structural collapse. In this study, experimental investigations into the performance of reinforced concrete beam-column joints strengthened with the carbon fiber-reinforced polymer(CFRP) were presented. The CFRP sheets were applied to the RC beam-column joint area with different configurations to determine the effective way to improve structural performances of joints. Based on the experimental study, it was concluded that the CFRP retrofit for the RC beam-column joints would be an effective way to provide the significant improvement of flexural capacity and ductility for the RC beam-column joints designed with non-seismic details.
