슬래브 유무에 따른 철근콘크리트 보의 구조성능 평가

In this study, experimental research was carried out to evaluate the structural performance of reinforced concrete beam using embedded carbon fiber bars and strengthening metal fittings in existing reinforced concrete building Test results showed that retrofitting specimens with embedded carbon fiber bars were increased the load-carrying capacity by 21～55%, retrofitting specimens with embedded carbon fiber bars and strengthening metal fittings were increased the load-carrying capacity by 21～48% in comparison with the standard specimen. Also, retrofitting specimens showed much higher ductility compared to retrofitting specimens with conventional method.
