An Experimental Study to Prevent Debonding Failure of RC Beams Strengthened with Near Surface Mounted CFRP

표면매립공법으로 휨보강된 RC보의 부착파괴 방지 상세에 대한 실험연구

This paper presents test results to prevent debonding failure of reinforced concrete beams strengthened with near-surface mounted(NSM) CFRP. Beams strengthened with different strengthening systems with externally bonded CFRP, NSM CFRP and NSM CFRP with mechanical interlocking. Test results indicated that using NSM CFRP is improved the stiffness and increased the flexural capacity of RC beams and NSM CFRP with mechanical interlocking prevented debonding failure of RC beams.
