摘　　要：对大跨度空间结构而言 ,风荷载作用是结构设计中的主要荷载之一。对于大跨度单层网壳结构的抗风设计 ,目前尚无设计规范可依。为对该类结构的风致振动进行深入研究 ,首先回顾和总结了大跨度单层网壳结构抗风设计方法及已有的风荷载模拟技术 ,并指出目前尚存在的问题 ,为大跨度单层网壳结构抗风分析提供借鉴。Wind load is one of the major loads in the design of a large span structures.At present,no corresponding items in criterions in effect can be referred to wind resistant design of the large span single layer reticulated shell structures.So it is very necessary to do further research on the wind excited vibration analysis of the structures.In this paper,current wind resistant design methods for the structures and the simulation techniques for wind action are reviewed and compared.Finally,the main problems in wind resistant research are presented.
