| Abstract |
Current codes of practice have specified the minimum and maximum shear reinforcement ratio to prevent the brittle shear failure of reinforced concrete members. These limits on shear reinforcement, however, are significantly different, and cannot consider the effect of longitudinal reinforcement ratio and shear span ratio on the shear reinforcement limits. Thus, this study proposed the minimum and maximum shear reinforcement ratio considering these influencing factors, and compared to test data from previous studies and other approaches. The analysis results imply that the proposed limits on shear reinforcement are very rational and proper for reinforced concrete members having various concrete compressive strengths and longitudinal reinforcement ratios. |
