摘要

摘要: 实际索膜工程的找形分析,不仅要得到稳定的结构形态,还要得到合适的索的预张力分布。基于非线性有限元找形理论,提出适时考虑索找力的索膜结构找形方法。首先根据是否考虑及何时考虑索找力,分3种情况对一个小品膜结构进行找形分析,发现只有适时考虑索找力的找形方法可以得到形态稳定、索张力分布合理的结构形态。然后采用新方法对大型索膜结构佛山世纪莲花体育场屋盖结构进行分析,发现新方法可以快速有效地对大型索膜工程进行找形和找力分析。

Abstract: Form-finding analysis of actual cable-membrane projects,does not only aim to find stable shapes,but also to find suitable cable pretension distribution.Based on the nonlinear finite element method pattern theory,it was proposed a method considering cable force-finding from the appropriate moment in the process of form-finding analysis.According to whether and when to consider force-finding of cables in the process of form-finding,three form-finding cases were considered.From analytic results,only the method considering cable force-finding from the appropriate moment could get a stable shape and a proper cable pretension distribution.Using the new method,the roof of a large cable-membrane stadium named Foshan Century Lotus was analyzed.It was found that the method could be used for the analysis of shape-finding and force-finding of large cable-membrane structures rapidly and effectively.
