| 摘 要： | 推导了任意边界条件下承受轴力及横向荷载的钢-混凝土组合梁的耦合变形微分方程,对组合梁的变形挠度进行了理论分析,研究了混凝土板与钢梁介面滑移的影响,同时探讨了因轴力而产生的二阶弯矩(p-δ弯矩)对组合梁变形的影响,可为钢-混凝土组合结构稳定性及极限承载力研究提供理论基础。

| Abstract: | This paper deduces a coupling differential equation about deformation of steel-concrete under axial compression and transverse loads with any boundary conditions.Its deflection is analyzed,the interface slip was taken into account,and the effect of the second-order bending moment on deformation was discussed which can offer groundwork for analysis of stability and ultimate bearing resistance of steel-concrete composite construction. |

| Keywords: | axial compression bending moment interface slip deformation |
