장방형 개구부를 갖는 고강도 철근콘크리트 깊은 보에서 개구부 경사보강철근의 전단저항 = Shear Capacity of Diagonal Reinforcements Around the Opening in the High-Strength Reinforced Concrete Deep Beams with Rectangular Openings

다국어 초록 (Multilingual Abstract)

For reinforced concrete deep beams with rectangular openings, the diagonal reinforcement around opening has greater effect on restraining the diagonal crack width and increasing the ultimate strength than the horizontal or vertical reinforcement around opening of the same steel amount The purpose of this study was to evaluate the relation between opening Size and amount of diagonal reinforcement requiring for complement of reduced strength Fifteen deep beams were examined according to the variety of the width and depth of opening as web as amount of diagonal reinforcement around opening Also, the concepts of volumetric ratio of diagonal reinforcement(Ρ_(od)) and of effective diagonal reinforcement factor around opening(ξ) were suggested Test results indicated that preservation of strength of deep beams with openings correspond to ultimate strength of solid beams calculated by strut-tie model of ACI 318-02 may be achieved by providing the effective diagonal reinforcement factor around opening of 0.05
