高强度 鐵筋콘크리트보의 剪斷擧動에 關한 硏究 = A Study on the Shear Behavior of High-Strength Reinforced Concrete Beam

다국어 초록 (Multilingual Abstract)

This study is how compressive strength of concrete to influence the shear behavior of reinforced concrete beam without web reinforcement. For this study, the compressive strength of concrete and admixture ratio are variable factors and the compressive strength of concrete is classified into three series - 250㎏/㎠(L-Series), 350㎏/㎠(M-Series), 600㎏/㎠(H-Series) - from low-strength to high-strength. In every series, cross section, compressive strength, longitudinal steel ratio and shear span to depth ratio are constant and admixture ratio is divided into two types and displacement control. After precise observing the evolution of crack, failure strength, measuring shear cracking strength, ultimate shear strength and performance of the mixed steel fiber to increase tension stress, their outcomes are analyszed and synthesized.
