摘　　要：通过将管板组合结构等效为正交各向异性板的方法,探讨该类结构的力学响应的计算方法.首先从平面问题本构方程出发,应用变形协调条件得到其等效材料参数,然后应用刚度分析法得到其等效厚度与等效密度,最后通过与3D有限元结果比较说明等效模型的正确性.The computational method of the mechanical responses of the tube-plate composite structure is given by putting the composite structure to an equivalent orthotropic anisotropic plate.First,the equivalent material parameters are obtained by combining the constitutive equations of the plane problems and the deformation compatibility conditions.Then the equivalent thickness and density of the plate are obtained with stiffness analysis.Finally,the correctness of the equivalent model is verified by comparing the3D-FEM results with those obtained by the present method.
