张力膜结构的设计与分析——某商业中心屋顶风雨操场

The design and analysis of tensile membrane structure--The sports facility roof of a commercial center

张力膜在大型体育场馆中的应用越来越多,其优点是支撑结构简单、跨度大、维护管理方便,但设计、施工方面有许多值得研究的地方.本文以风雨操场为例,结合动力松弛法找形的快捷和非线形有限元法荷载分析的精确,给出大型张力膜结构设计与分析的方法和流程,总结了膜结构工程设计中找形和荷载分析的内在联系,能给同类工程提供有益的参考.

Now more and more large-scale gymnasiums adopt membrane structures as their roofs. Simple supports, large spans and easy maintenance are the advantages of membrane structures. However the design and construct need us to study. Based on the fast shape-finding of the dynamic relaxation method and the accurate load analysis of the nonlinear finite element method, this paper summarizes the design method of the membrane and detects the relation between the shape-finding and load analysis. Some conclusions for the membrane projects are put forward in the paper.
