In this study, experimental research was carried out to improve and evaluate the seismic performance of reinforced exterior concrete beam-column joint strengthened with different anchorage length of embedded CFRP Rods in existing reinforced concrete building.
Test result shows that retrofitting specimen(RBCJ-SR2T1, SR2T2) designed by the improvement of seismic performance of reinforced concrete beam-column joints, maximum load-carrying capacities were increased 2.24 ~ 2.24 times in comparison with the standard specimen(RBCJC). Also, retrofitting specimens showed stable hysteretic behavior compared to the standard specimen(RBCJC).
