索膜结构分离分析和整体分析研究

Research on Respective Analysis and Collaborative Analysis of Cable-Membrane Structures

索膜结构由柔性材料组成,其成形及承载都依靠预应力来实现,故其设计首先需要进行找形分析和荷载分析。本文对索膜结构的分离分析和整体分析进行了对比研究,通过计算实例表明两种方法的差别是巨大的,指出了整体协同找形分析的必要性。

The material composing cable-membrane structure is soft, so it should be prestressed to take shape and be loaded. Thus,above all, form-finding and load-analysis are required. This paper researches into the differences between respective and collaborative analysis of cable-membrane structure. The necessity of collaborative form-finding analysis has been proved by the differences between results whether the influence of membrane is considered or not.
