요약1 본 연구에서는 장방형 개구부가 설치된 철근콘크리트 깊은 보에서 개구부 보강철근의 하중전달 모델을 제시하고, 이를 바탕으로 개구부 보강철근의 배근방법에 따른 전단거동의 변화를 실험적으로 평가하는데 주요 목적을 두었다.
요약2 The objective of this study was to evaluate the shear capacity of opening reinforcement in reinforced concrete deep beams with rectangular openings. Main variables were shear span-to-overall depth ratio(a/h), and the configuration of opening reinforcement. The size of opening was 0.5a×0.3h and the location of centerlines of openings and shear spans were the same for all specimens. Opening reinforcement identically consisted of three 10 mm diameter deformed bar of 4,000kgf/cm2 yield strength. The vertical reinforcement was U-typed stirrups in top and bottom of opening. The horizontal and 45 degree diagonal reinforcements were arranged in both sides of the beams and anchored according to KCI code method. In the following, the performance of opening reinforcement was described according to the variety of configuration of reinforcement and a/h. Based on previous and this experiments, an equation estimating the shear capacity of opening reinforcement was suggested through considering the average tie-action and the equilibrium of energy of opening reinforcement along the fracture surface in deep beams with openings.
