鐵筋콘크리트 보에서 剪斷鐵筋이 휨耐力에 미치는 影響 = Effects on Flexural Capacity of Shear Reinforcement in Reinforced Concrete Beam

다국어 초록 (Multilingual Abstract)

Shear reinforcement has an important role to strengthen shear capacity of reinforced concrete beam. Although the flexural design corresponding to design code does not consider the effects of the shear reinforcement, its utilization in flexural region leads to the improved ductility and the enhanced strength by confining concrete. It allows to design the over-reinforcement beam. In this study, we considered the effects of the shear reinforcement on the flexural ductility and strength of reinforced concrete beam according to the spacing of shear reinforcement, steel ratio, and shear span ratio. The flexural capacity depends on the amount of longitudinal bars and the ductility the confinement degree by the shear reinforcement. The flexural analysis varies with the stress-strain relation of confined concrete. The analytical results based on the stress-strain relation presented by Chung almost corresponded to the experimental ones. It was observed that the proper design of shear reinforcement leads to utilize the over-reinforcement concrete beam.
