摘要
本文在进行了十六根高强混凝土无腹筋约束梁试验研究的基础上,着重讨论了剪跨比、纵向钢筋配筋率对高强混凝土无腹筋约束梁抗剪强度的影响及其变化规律,提出了集中荷载作用下高强混凝土无腹筋约束梁抗剪强度建议计算公式。
Sixteen reinforced high-strength concrete restrained beams were tested under concentrated loading. In this paper, not only the effects of shear span ratio and rate of reinforcement on shear strength are investigated, but also the law of shear strength with their change are pointed out. Based on analysis of the tests' results,the formular and the limits corresponding to the eduation about shear strength of rein- forced high-strength concrete beams under concentrated loading are proposed by means of statistical regression.
