| 摘 要： | 网壳结构节点和杆件的数目繁多，使内力分析模块所需的输入数据大大地增加，这就使工程设计人员难以直观而迅速地检查输入数据正确与否。本文介绍了在AutoCAD2000平台上采用VAB开发工具建立球面网壳几何模型的方法，详述了凯威特网壳几何造型特点及程序实现过程：通过AutoCAD与FEA分析程序的结合，为通用有限元程序中网壳结构的建模提供了一种新方法。

| Abstract: | Reticulated shell is composed of lots of elements and joints, the input data is very large in the process of mechanical analysis, and it is very difficult to guarantee the validity of the input data. Geometry model method in AutoCAD about sphere reticulated shell is introduced. The geometric characters and programming procedures of Kiewitt-reticulated-shell model are discussed in detail. The weakness of reticulated structure model building which exists in general finite element analysis programs has been solved, and combined application of AutoCAD and FEA analysis programs has been implemented. |
