组合桁架中同时考虑滑移和掀起影响的理论分析──关于钢－砼组合桁架系列研究之七

THEORETIC ANALYSIS OF COMPOSITE TRUSS WITH SLIP AND UPLIFT EFFECTS CONSIDERED ──THE SEVENTH OF THE SERIAL RESEARCHES ON STEEL-CONCRETE COMPOSITB TRUSS

迄今国内外文献有关组合梁的部分交互作用理论均忽略掀起影响．本系列研究率先在组合桁架中同时考虑滑移和掀起影响．理论和测试研究分三部分：本文是关于轴力Ｆ（ｘ）的六次线性非齐次微分方程推导的理论分析．有关方程的具体求解、理论公式与测试值比较将陆续发表，具有深层的理论意义和实用价值．

Uplift effect has been neglected in the partial interaction theory about composite beams. A serial research is made which tubes slip and uplift effects into account at the same time.The series includes three papers with theory and test studies. The first paper is the theoretic analysis about the deriving of six order differential equation on the axial force F(x). The concrete solution of the equation and the comparison of theoretic results with test values will be dealt with in other two papers. The researches may indicate profound theoretic and practical value.
