摘要
介绍了超大跨度屋盖结构———北京首都机场 3号航站楼的模型风洞试验概况和主要结果 ,给出了屋面在最不利工况下的分块体型系数 ,清楚地显示了屋面的风压分布特征。采用考虑多模态及模态间耦合效应的CQC法计算结构风振响应 。
The test conditions and main results of wind tunnel test for Terminal 3 at Beijing Capital Airport are introduced.The block shape coefficients for the most unfavorable conditions are given,which clearly show the characteristics of the wind pressure distributions on this long-span roof surface.The dynamic responses are computed by the Complete Quadratic Combination(CQC)method, which takes modal coupling effects into account.The equivalent static wind loads are findlly computed by using the gust loading factor method.
