Shear Capacity of Reinforced Concrete Haunched Beams by Shear Span-to-Depth Ratio and Haunch Slope
경간비와 헌치 기울기 변화에 따른 철근콘크리트 헌치보의 전단성능에 관한 연구
Abstract
Reinforced concrete haunched beams have been used for enhancement of shear resistance of beams to avoid the stress concentration. But American and British codes do not give my formula for the design of haunched beams. The purpose of this research is to experimentally investigate the shear failure of reinforced concrete punched beams for various haunch inclinations and shear span-to-depth ratios. The experimental results showed that even though shear behavior of haunched beam were similar to that of resembled rectangular beams, shear span-to-depth ratios and inclinations of haunch had effects on shear cracking strength.
