钢筋混凝土 T 形截面梁的斜截面承载力研究——对《规范》计算方法的改进意见

Investigation on the Shear Strength of R.C.T Beam

本文通过５根钢筋砼矩形截面梁和１４根Ｔ形截面梁的剪切破坏试验的对比，发现翼缘的变化并未对Ｔ形梁的斜截面抗剪承载力产生明显的影响。因此，对《规范》中Ｔ形截面梁在集中荷载作用下的抗剪计算方法提出了合理的修改建议。

In the paper,some shear strength testing data of 5 R.C.Beams with rectangular section and 14 R.C.Beams with variant T shape section are compared.The authors find out that the flanges of T shape beams have no obvious effect on its shear strength.So, a reasonable suggestion for improving the calculation method given by the code is presented.
