摘　　要：简要介绍了近年沿海地区台风引发的膜结构风损事故,说明了风场的复杂性。建议采用抗风多级设防原则合理进行膜结构抗风设计。针对膜面撕裂是膜结构风损的主要形态,具体分析了膜面撕裂破损的原因。从设计、制作、安装到使用等方面提出了相应的防范措施,以增强膜结构防御灾害的能力。The wind damage accidents of membrane structures caused by typhoon are introduced, and the complexity of wind field is described. Then, the advises that wind resistance design of membrane structures should adopt multilevel protection principle, are put forward. Considering membrane tearing is the main form of structural damage induced by wind, the reason of membrane tearing is analyzes in detail. The corresponding countermeasures are presented to increase the disaster proof ability of membrane structures from different aspects, such as design, fabrication, adjustment and application, etc.
