摘　　要：世博轴膜结构是典型的风敏感结构。气动弹性模型风洞试验是研究其风振响应的有效方法,但由于膜结构质量轻、刚度小,目前在实际抗风研究中很少应用。为此,以世博轴膜结构为对象,通过风洞试验进一步了解了大跨度膜结构的风振响应特性,获得了这类结构的风振系数。Membrane roof for central axis of the 2010 Shanghai Expo is a kind of typical wind-sensitive structures due to their flexible and light features. Aero-elastic models are effective to investigate responses of the structures under strong wind actions. Because of the soft and light features of the membrane, the aero-elastic model has been seldom used in practical application. Membrane roof for central axis of the 2010 Shanghai Expo is taken as the example of the present research. The wind fluttering factor of the large-span membrane structure are summarized by the wind tunnel test.
