摘要
介绍了上海铁路南站模型风洞试验概况和主要试验结果。对这一大跨度圆形屋盖,分别进行了在无周边建筑和有周边建筑情况下的风洞模型试验。试验结果表明周边建筑对所测建筑的风荷载有较大的气动干扰影响。最后分析了屋盖上的典型测点的平均风压系数随风向角变化的曲线。试验结果对类似的圆形屋盖结构的风压分布具有参考价值。
Testing conditions and main results of the wind tunnel test of the model of Shanghai South Railway Station are introduced. For this circular dome, the wind tunnel test is carried out with and without the surroundings. The test results show the significant interference effects from its surroundings. Finally, The mean wind pressure coefficients of a part of typical measuring points as a function of wind direction are analysed. The test results can be used as references for similar circular domes.
