| 摘 要： | 利用可以考虑边界位移影响和锚固基础共同作用的索膜结构非线性有限元程序，针对简单的张拉索膜结构模型，对张拉索膜结构与其锚固基础的共同作用进行了一系列分析，讨论了膜结构本身在应力与位移等方面的影响，着重研究了张拉索膜结构对锚固基础抗拉刚度和位移限度方面的要求．利用分析结果，对张拉索膜结构中的锚固基础设计方法进行了评述，可供实际工程人员参考。

| Abstract: | Based on a non-linear FEM program of the membrane structure, a simple tensile membrane structure model was established and a series of parameter analyses were conducted to study the interactions between the membrane structure and its anchor foundation.The stresses and displacements of membrane structure were discussed and the emphases were put on the requirements of its anchor's tension stiffness and the displacement limitation.With the computation results,the evaluations of the main anchor foundations were presented. |
