摘要
根据７０根梁斜截面剪压破坏的试验资料，推算出梁剪压区的水平压应力σｘ和剪应力τｘｙ，并据此给出了剪压区混凝土压剪复合受力强度的计算公式。该式隐含了竖向压应力σｙ的影响，间接地考虑了斜截面上的骨科咬合力和受拉钢筋的销拴作用，且较为简单，可用于建立梁斜截面受剪承载力计算公式。
Bed on the test data of 70 reinforced concrete beams which fail by crushing of the concrete in the shear-compression sone,a expression of the strength of concrete in reinforced concrete beam under a combined states of stresses is presented in this paper. The effect of the wiltal compression stress σy on the shear strength of concrete is included and the action of aggregate interlocking and dowel forces are taken into account indirectly in the expression. The expression is simple in form and can ueed to establish the shear strength of reinforced concrete beam.
