고강도 철근콘크리트 보의 전단종국강도 산정식의 제안

The purpose of this paper is to suggest the equations that are able to predict the ultimate shear strength of the reinforced high-strength concrete beams. For this analysis, total of 83 rectangular beams were tested, and existing data of 400 was adopted. Through this analysis, the following equations are obtained. a) Shear Tensile Failure Equation : TVu={K1.K2(3.02 $\sqrt[3]{\Fc}$/$sqrt{\a/d\}$+1.74Pt)+(0.18a/d+0.567)Pww$\sigma$y]bd b) Shear Compressive Failure Equation : cVu={(29.85 $\sqrt[3]{\Fc}$-130)$\sqrt{d/a}$+(0.089$\sqrt{a/d}$=0.04)Pww$\sigma$y}bd
