초록
In this study, experimental research was carried out to improve and evaluate the seismic performance of reinforced concrete beam-column joint using Groove and Embedding FRP Rod and CFRP Sheet in existing reinforced concrete building.
Test result shows that retrofitting specimen(RBCJ-SR2, SRCB2) designed by the improvement of seismic performance of reinforced concrete beam-column joints load-carrying capacities were increased 1.78 ~ 2.29 times in comparison with the standard specimen.
