【摘要】 本文分析了国内外33个研究者的568根集中荷载下无复筋简支矩形截面钢筋混凝土梁的抗剪强度试验数据,在此基础上,针对长梁（M/Qh₀≥2.5）和短梁（M/Qh₀<2.5）不同的剪力传递机构和破坏特点,分别提出了其抗剪强度计算的回归公式。计算结果同试验结果吻合良好。更多还原

【Abstract】 This paper analyzes the shear strength of 568 simple rectangular section beams without web reinforcement subjected to concentrated loads. Regression formulas for the calculation of shear strength are suggested to different shear transfer mechanisms and characteristics of failure of short and long beams. Results measured and calculated by these equations are in good agreement.更多还原
