In this study, experimental research was carried out to evaluate the structural performance of the reinforced concrete beam retrofitted by strengthening methods(embedded FRP rod of hexagon, metal fittings) in existing reinforced concrete buildings. Test results showed that the maximum load carrying capacity of retrofitted specimens(BCR, BCR-AC1, BCR-AC2) were increased by 55%, 47%, and 52% respectively in comparison with the standard specimen BSS.
