摘要
利用基本力学方法对钢-混凝土双面组合梁在均布荷载作用下的滑移效应进行分析,推导得到了负弯矩区上、下交界面滑移沿梁长方向的表达式,并通过算例比较了双面组合梁与传统单面连续组合梁的滑移特点。计算表明,与传统单面连续组合梁相比,钢-混凝土双面组合连续梁不仅在负弯矩区提高了截面承载力,也使截面刚度得到了提高。
The paper makes a research on the interface slip of the double steel-concrete composite beam under uniform load by the primary mechanical principle. The slip＇s formulas along the span direction are obtained and an example is used to make a comparison between the slip features of the double steel-concrete composite beam and the traditional continuous steel-concrete composite beam. It is shown that compared with single steel- concrete continuous composite beam, double steel-concrete continuous composite beam has not only enhanced its load-carrying capacity of negative bending zone, but also improved its section rigidity.
