摘要
介绍了钢筋混凝土无腹筋梁斜截面抗剪的影响因素,对中欧规范抗剪承载力的计算公式以及抗剪最小配筋率的有关规定进行了对比分析。从而得出中国规范和欧洲规范在混凝土低强度的条件下计算结果相差不大,但在高强度的条件下,中国规范的可靠度指标低于欧洲规范。
This paper introduces the factors which affect the shear force resistance of beams without web reinforcement, analyzes the formula for calculating the shear strength and the minimum shear reinforcement ratio of Chinese and European standard. The comparisons indicated that the results more or less with the Chinese and European standards under lower concrete strengh, but higher concrete strengh, the Chinese reliability index is lower than the European.
