摘要
作为一种典型的柔性张力体系,膜结构的分析方法与刚性结构相比有许多不同之处,形成一套独特的理论体系。首先阐述了膜结构分析理论的特点和一些需要特殊考虑的问题,然后从初始形态分析、荷载效应分析和裁剪分析三个方面概要介绍了膜结构分析理论的发展过程,以及一些具有代表性的方法;继而针对膜结构分析中的若干热点问题,包括褶皱的数值模拟、考虑多目标的形态优化、基于裁剪-找形一体化思想的精确成形技术和考虑流固耦合的风振分析方法等的研究现状进行了评述,最后对膜结构分析理论的进一步发展提出展望。
As a typical tensioned flexible system, membrane structures have a set of unique analysis theory compared to that of the traditional rigid structures. The features and some special problems of the analysis theory of membrane structures are stated firstly. Then the development of the analysis theory of membrane structures is introduced from three aspects, form-finding analysis, loading effects analysis and cutting pattern design. Some typical methods of these three aspects are focused on. Next, some hot spot issues on the study of membrane structures are discussed, including the numerical simulation of wrinkling, the multi-objective shape-state optimization, the accurate surface-forming based on the integration of form finding and patterning analysis, and the wind-induced vibration analysis with the consideration of wind-structure interactions. Prospects on the development of the analysis theory of membrane structures are proposed finally.
