摘要
分析了深梁、浅梁和短梁斜截面应力分布规律和抗剪机理， 得出影响砼受弯构件斜截面抗剪承载力的主要因素是剪跨比ａ／ｈ０ 的大小， 而跨高比ｌ／ｈ 的大小对斜截面抗剪承载力的影响甚微， 在抗剪计算中可以忽略不计的新结论。
The analysis of the stress distribution law and mechanism of deep, shallow and short beams under shear has shown that the main factor affecting loading capacity of reinforced concrete flexural member is a/h 0,the ratio of shear to span and that l/h , the ratio of span to depth has little effect on shear loading capacity, which can be ignored in the calculation of this capacity. Based on the above conclusions, a calculation method for shear loading capacity of reinforced concrete flexural member considering a/h 0 as a main factor is proposed.
