摘要： 本文根据五十片梁的抗剪试验结果,描述了具有不同预应力度、剪跨比、配箍率及截面形式的梁在荷载作用下斜裂缝的产生和发展以及梁的破坏情况,分析了预应力度、剪跨比及截面形式对斜截面抗裂性的影响,提出了斜向开裂时剪力值的计算公式,并与国内外一些文献的公式作了比较

Abstract: Based on the results of shear test of 50 beams, this paper describes the behavior of beams with different degree of prestress, shear span to depth ratio, concrete strength and shape of section under loading and emphatically analyzes the influence of degree of prestress,shear span to depth ratio and shape of section upon the diagonal cracking load. A formula for estimating the diagonal cracking load is proposed and a comparision between the formula in the paper and these in some other reference is made.
