| 摘 要： | 采用数值风洞技术数值模拟上海世博和谐塔的绕流场,获得了三维复杂结构的绕流场和风荷载参数。充分结合现有的计算技术和硬件计算能力,把整体结构的数值模拟分解为核心圆筒加外围弧形铝板部分,以及桁架体系部分。利用前者得到的等效局部风环境来评估桁架体系的风荷载,从而得到整体的风荷载参数。通过与物理风洞的试验结果进行对比可以认为数值风洞的结果是可信的。

| Abstract: | The numerical wind tunnel technique is employed on the Harmony Tower of Shanghai World Expo, and the complex three-dimensional structure of the flow field and the wind load parameters are obtained.The wholel structure is decomposed to a core cylinder radial and external aluminium parts,and the parts of a truss system.The equivalent of the former local wind environment truss system is used for assessing the wind loads,and thus the overall parameters of wind load can be obtained.By comparing with the wind tunnel test results,the results of numerical simulation are credible. |
