网壳结构作为一种新颖的建筑型体.在我国已开始得到重视并用于实际工程.但由于网壳结构形体的多变性和众多单元数量,当用计算机进行结构分析和设计时,前期工作量很大.因此,本文在分析了网壳结构形体的基础上,提出了结构的成形策略,并引进了一套易在计算机上实施的、指示结构几何构成的算法,用指示矩阵算法实现了网壳结构的前处理.使用结果表明,本法简单、正确、有效,是用于结构前处理的一种较为系统的方法.
The reticulated shell structure is a novel construction type body. It has been paid attention to and used in actual projects in China. However, due to the variability of the shell structure and the number of units, when using a computer for structural analysis and design, the initial workload Therefore, on the basis of analyzing the shape of the reticulated shell structure, this paper proposes the forming strategy of the structure, and introduces a set of algorithm that is easy to implement on the computer and indicates the geometric structure of the structure. The algorithm is implemented using the indicator matrix algorithm. The pretreatment of the shell structure. The results show that this method is simple, correct and effective. It is a more systematic method for structural pretreatment.
