| 摘 要： | 针对广州西塔项目进行了同步压力测试试验,研究和分析了广州西塔的平均风压和极值风压分布规律。利用气象资料对幕墙风压进行修正,明显降低了西塔结构中上部的风压值,提供了更为科学合理的结构风荷载数据,同时也保证结构设计的安全性和经济性。通过截面体型系数的比较,可以看到西塔截面的体型系数和圆截面的体型系数具有一定的相似性。相关的研究结果可供结构工程师参考。

| Abstract: | Mean and fluctuating pressures on the Guangzhou West Tower were measured by wind tunnel experiment.Mean and peak pressure distributions on Guangzhou West Tower are discussed in this paper.The pressures on the cladding are corrected by the climate data of the site of Guangzhou West Tower.In this way,the pressures on the upper region of structure are decreased distinctly.It makes the wind pressure more scientific and reasonable.Meanwhile it ensures the safety and economy of the structure.The shape coefficient... |
