摘要
本文在基本假设的前题下,分析了矩形网格离散结构的变形以及变形量与内力之间的本构关系。在此基础上,通过建立等级模型,运用虚功原理推导出网格扁壳的作线性基本控制方程与边界条件。
Based on fundamental assumptions,an analysis of the constitutive relations between the internal forces and deformations of discrete rectangular reticulated structures is given.On the basis of this,an equivalent continuum model is ad-opted and the application of the principle of virtual work leads to non-linear go-verning equations and corresponding boundary conditions.
