摘要
由于膜结构特殊的力学特点 ,其结构分析与设计过程明显不同于传统结构。着重对膜结构荷载态分析中的一些主要问题进行了探讨 ,包括荷载取值、特别是风荷载的确定方法 ;荷载态分析的方法及需要注意的一些问题 ;常见的膜结构分析软件等。在此基础上 ,介绍了如何根据计算结果来判定结构性能的优劣 ,以及设计膜、索及索具等构件。
Due to the unique mechanics characters, the analysis and design process of membrane structure is quite different from traditional structures. In this paper,some key problems of membrane structure analysis were discussed. The first question is how to determine the load case, especially for wind effects. Then, the structural analysis methods and some questions should be note were presented. It also introduced some design software of membrane structures. Moreover, it is recommended in this paper that the specified maximum displacement and stress of membrane structure, which can be used to assess the structural performance and select cable and membrane members.
