摘要(Abstract):

介绍了武汉体育中心体育馆风洞试验模拟方法和试验结果,讨论了不同风向角下屋盖表面风压的分布,并得出风荷载的分布规律。在考虑了上游有建筑物影响的情况后,分析了周围建筑对屋盖表面风压的干扰效应。围护结构的设计风压分别由我国规范和基于随机振动理论的标准方法计算所得,通过两种方法的比较,得到了若干结论。
The approach and main results of the wind tunnel test of the gymnasium of Wuhan sport center are introduced.Wind pressure distributions of roof in different wind directions are analyzed and the contour curves of mean wind pressures on the roof are obtained.In the meantime,the interference effects of the surrounding buildings on the roof are analyzed.The designed wind pressure of building is presented by the code method and statistical method based on random vibration theory respectively.By comparison of the results presented by these two methods,some conclusions are obtained.
