| 摘 要： | 采用栓钉等柔性抗剪连接件的钢-混凝土组合梁交界面上存在相对滑移变形,增大了组合梁的挠度。论文研究了冷弯薄壁U型钢-混凝土组合梁的滑移性能,推导了滑移量的计算公式,建立了考虑滑移效应的钢-混凝土组合梁在均布荷载作用下的挠度计算公式。分析表明：滑移效应对组合梁挠度影响不能忽略。

| Abstract: | The effect of slip existing at the interface between the steel and concrete on the composite beams with flexible connectors increases deflection of the composite beams.This paper theoretically studied the slip property of the cold-formed thin-walled U steel-concrete composite beams,gave the calculation formulas of slip,and proposed the formulas of simplified deflection in consideration of slip effect in composite beams.The mid-span deflections were calculated under the uniform load.it is shown that the effe... |
