| 摘 要： | 为了研究钢－混凝土组合梁正弯矩区的组合抗剪性能,本文对16根密实截面钢－混凝土组合梁的组合抗剪性能进行了试验研究。在试验研究中,为了分离组合梁各抗剪部分承担的剪力,需要计算钢梁腹板所承担的剪力。本文介绍一个钢梁腹板在塑性流动阶段的剪应力计算方法,并且该方法还能判断钢材是否进入强化阶段。为了验证这一方法的正确性,作者还进行了2个纯钢梁试件的抗剪试验,试验结果与计算值吻合良好。

| Abstract: | Experiments are conducted on sixteen specimens of simply supported composite steel-concrete beam with compact steel section to investigate their behavior of shear resistance. Above all, the vertical shear resisted by joist is calculated to investigate the vertical resisting shear capacity of shear force components of composite beams in experimental research on composite shear behavior of steel-concrete composite beams under sagging moment. In this paper, one method on stress analysis of webs of steel joists is introduced to compute shear stress in plastic range, and this method can estimate whether the stress state of steels is within strain-hardening range. Experiments were conducted on two specimens of steel beam with same section to validate this method. Test results show that the calculating results of this method agree with the collected data well. |
