An Experimental Study to Prevent the Delamination of the CFS with End-Anchorages

탄소섬유 보강부재의 단부탈락 방지 방안에 관한 실험적 연구

The strengthening of concrete structures in situ with externally bonded fiber sheets is increasingly being used for repair and rehabilitation of existing structures. Because fiber sheets is attractive for this application due to its good tensile strength, resistance to corrosion, and low weight. But, debonding failure may occur at the beam ends that fiber sheet bonded to the soffit of a beam. The method which can prevent debonding failure is suggested and proved its efficiency by using CPS experimental test. And this paper summarized the results of experimental studies concerning the end-anchorage system. Results show that the suggested method is faithful in strengthening with CFS.
