钢与混凝土组合梁考虑滑移与剪切变形的再分析

Analysis of Steel-Concrete Composite Beams Considering Effects of Relative Slippage and Shear Deformation

对于工程中常用的钢与混凝土组合梁,考虑了受力变形时结合面间的相对滑移和竖向剪切变形的影响,用最小势能原理导出了控制微分工程,给出了解分析结果,并通过算例对钢与混凝土组合梁的横截面的应力及位移的计算结果进行了分析。

With the consideration of effects of relative slippage and shear deformation, the controlling differential equations of steel-concrete composite beams by means of minimum potential energy principle is presented in this paper.In this procedure the closed form solutions are given, and numerical results ofstresses and deflections are analyzed which can provides references for the engineering designers.
