摘要
对适筋的钢筋混凝土实心及空心矩形截面纯扭构件,当取其截面高宽比、纵筋及箍筋配筋率,以及二者的配筋强度比基本相同,而具有不同的截面尺寸,对空心截面并具有不同的有效壁厚时,进行试验研究分析,提出了钢筋混凝土矩形截面纯扭构件截面尺寸对承载力影响的规律性,为今后建立构件受剪扭的统一计算公式,打下基础.
The experimental study of the solid and hollow rectangular reinforced concrete section under pure torsion is based on that, the ratio of high to width of the section, the reinforcement ratio of the longitudinal to the stirrup, and the strength ratio of the longitudinal to the stirrup are taken basically as the same, while the section sizes and the effective wall thickness of hollow section are taken different. The regularity of the effects of the section size of rectangular reinforced concrete member under pure torsion on the carrying capacity is presented. It could be the base of the unified formular for shear and torsin.
