In this study, experimental research was carried out to improve and evaluate the seismic performance of reinforced concrete beam-column joint using Embedded Carbon Fiber Rod and Carbon Fiber Sheet in existing reinforced concrete building.
Test result shows that retrofitting specimen(LBCJ-SP45, CS2, CRUS) designed by the improvement of seismic performance of reinforced concrete beam-column joints load-carrying capacities were increased 1.34 ~ 1.54 times in comparison with the standard specimen.
