钢-砼组合桁架部分交互作用理论分析

Theoretic Analysis of Partial Interaction about Steel-Concrete Composite Truss

目前组合结构设计计算中有关组合梁的部分交互作用理论均忽略掀起影响率先在组合桁架中同时考虑滑移和掀起影响，推导出关于轴力Ｆ（ｘ）的六次线性非齐次微分方程。

Uplift effect has been neglected in the partial interaction theory about composite beams in the design and calculation of composite structures.The slip and uplift effects in composite truss are taken into account at the same time,and six order differential equation on the axial force F(x) is derived.The researches may indicate profound theoretic and practical value.
