摘要为了研究结构参数对复杂大跨空间结构风致振动的影响，以上海南站工程屋盖结构为例，利用基于非定常风荷载的风致动力响应频域分析方法，对结构的抖振响应进行参数分析。 - In this paper i was in virtue of the fluent software , set up the geometrical model of jin ’ ao mansion and adjacent buildings , used non - equilibrium wall functions to deal with the problem which come from the near wall , used realizable k - turbulent model to simulate the steady flow around 3d high - rise buildings , we can get the distribution of mean wind pressure coefficient of the surface of jin ’ ao mansion and five aerodynamics components . they were compared with the data from the wind tunnel test , we found out the distance between the result of the wind tunnel test and numerical simulation in the acceptable range
本文以fluent软件为平台,建立金奥大厦及其周边建筑的计算几何模型,近壁区采用非平衡壁面函数法处理,运用基于雷诺时均的realizablek -湍流模型进行高层建筑三维定常风场数值模拟,获得金奥大厦表面时均风压系数分布及基底五分量气动力,并和风洞测压试验的结果及风压系数积分计算的基底五分量气动力相比较,发现两者之间的差异在可接受的范围之内。
