摘要
对均布荷载作用下简支钢-混凝土组合梁的界面交互作用进行了理论研究。利用弹性体变形理论,推导并建立了简支钢-混凝土组合梁关于界面竖向掀起作用的常系数线性微分方程。求解此微分方程可以得出组合梁掀起力沿梁长的分布表达式,在栓钉间距范围内积分即可以算出栓钉所受掀起力的大小,该方法计算值与试验结果吻合良好,从而为栓钉的抗掀起设计提供理论计算依据,具有深层的理论意义和实用价值。
This paper deals with the interface slip and uplift of steel-concrete composite beam under uniformly distributed loads. Using elastic deformation theory, the differential equations on the axial force and uplift force are derived where the slip and uplift effects in steel-concrete composite beam are taken into account at the same time. These equations can not only describe the uplift force distribution, but also account for its effect on the deformation. The researches may indicate profound theoretic and practical value.
