강섬유로 보강된 철근콘크리트 연결보의 전단성능 평가

Abstract

The purpose of this study is to evaluate the shear performance of coupling beams with hooked end steel fibers. In order to evaluate the degree of reinforcement of the steel fibers volume fraction, the fiber volume fraction ratio was planned to be 0, 1, 2%, and the experiment was conducted. As a result of the experiment, it was confirmed that the maximum shear strength and ductility increased as the fiber volume fraction ratio increased. Accordingly, it is judged that the steel fiber increases the shear performance of the coupling beam specimens.
