集中荷载钢筋混凝土有腹筋梁的受剪承载力

Shear Resistance of Reinforced Concrete Beams Under Concentrated Load

根据国内外的大量试验资料，研究了混凝土强度、剪跨比和配箍率对集中荷载作用下钢筋混凝土箍筋梁的受剪承载力影响规律。在笔者原已提出的集中荷载钢筋混凝土无腹筋梁的受剪承载力计算公式基础上，给出了概念明确。

Based on the analysis of the numerous test data,the effects of the concrete strength,the shear-span to depth ratio,the reinforcement ratio of the stirrups on the shear resistance of reinforced concrete beams subject to concentrated load are investigated.The formulas are proposed to calculate the shear resistance of reinforced concrete beams,they are simple and in better agreement with a large number of the experimental data,and available for practical design.
