Behavior of Wedge-Type Anchor System for External Prestressing Method with CFRP

외부 긴장 보강을 위한 탄소섬유 복합재료용 쐐기형 정착구 거동

This paper present test result to develop wedge-type anchor system for external prestressing method with CFRP. The test results indicated that the lower a slope angle and elastic of wedge are, the higher ultimate strengths are for plate types. Bar types showed premature failure because of local high stress in FRP of anchor system. Therefore, to improve the strength for bar types needs further work of strengthening sleeves, slope angles of wedge and materials.
