摘要:
利用风洞试验对上海北外滩酒店中庭大跨度屋盖的1:200比例模型在各种风向角下的风压分布情况进行了测试,研究了中庭结构在不同方向风荷载作用下风压的变化情况。用统计方法对试验结果进行了分析,并与按规范方法计算的结果进行了比较。结果表明,对于结构正风压,除了立面下侧小部分外,按统计方法得到的计算值比按规范计算的值大,应作为设计荷载; 对于结构负风压,按规范计算的值比按统计方法得到的计算值大,应作为设计荷载。该研究可为精确计算风荷载提供依据,对工程设计有较好的参考价值。
Abstract:
The behavior of wind pressure distribution on the atrium with long-span roof of Shanghai North Bund Hotel under different wind directions angle was investigated through a 1:200 model wind tunnel test. The variation situations of wind pressure on atrium structure were measured and studied under different directions wind load. The testing results were analyzed based on statistical method and compared with those based on the code method. The result indicates that most testing values are larger than the calculated values for positive wind pressure of atrium, but smaller for negative wind pressure. The larger values should be used as the design load. Therefore, it is vital to determine wind load precisely for engineering design of such important structures through comparing analysis.
