介绍中国国家大剧院模型表面风荷载的风洞实验结果。首先对它的半椭球表面在大气边界层中的风压分布及增加表面粗糙度的影响进行研究 ,实验结果表明在不同风向下它的风荷载具有很好的规律性。有环境影响的对比实验结果表明人民大会堂对大剧院的风荷载有较大的影响。
The wind tunnel experiment results of surface wind load of China National Center for the Performing Arts are introduced. Firstly, the influence of the pressure distribution and the increase of surface roughness on the surface of the semi-ellipsoid in the atmospheric boundary layer is studied. The experimental results show that the wind load has good regularity in different wind directions. The comparative experiment with the environmental impact shows that the Great Hall of the People has a great influence on the wind load of the Grand Theater.
