초록

In this study, experimental research was carried out to evaluate the structural performance of the reinforced concrete beam retrofitted by strengthening methods(embedded CFRP rod of hexagon, CFRP Sheet) in existing reinforced concrete buildings.
Test results showed that the maximum load carrying capacity of retrofitted specimens(NER2, NER2-C) were increased by 1.46 ~ 1.67 times respectively in comparison with the standard specimen(NBS).
