分析了广义剪跨比、混凝土强度、腹筋和纵向钢筋对钢筋混凝土梁斜截面受剪承载力的影响。采用多项式相加的形式,用统计分析的方法,对收集到的307根集中荷载下剪压破坏梁的试验数据进行了分析研究,建立了具有95%保证率的斜截面受剪承载力统计计算方法。对比计算结果表明,该方法与试验结果符合较好。
The influence of general shear-span ratio, concrete strength, web reinforcement and longitudinal reinforcement on the shear capacity of RC beams is analyzed. By means of polynomial summation, the experimental data of 307 collapsed failure beams collected under concentrated load were analyzed by statistical analysis method, and the statistic calculation of shear strength of inclined section with 95% guaranteed rate was established method. The comparison results show that this method is in good agreement with the experimental results.
