강섬유 보강 철근콘크리트 연결보의 변형능력 평가

초록

If coupling beams have large deformation capacity, excellent seismic performance of the structure can be expected when the lateral force such an earthquake acts. Steel fiber reinforced concrete has a crack control effect due to the cross-linking action of the steel fiber and tensile strength and shear strength of concrete are increased, so it can replace part of shear reinforcement. These advantages can be expected in the ductile behavior of steel fiber reinforced members. In this study, the cyclic lateral loading tests were performed to evaluate the deformability of steel fiber reinforced concrete coupling beams.
