| 摘 要： | 建立了金茂大厦三维数值模拟模型,模拟得到的大厦表面上有代表性点的平均风压系数与风洞试验结果1]基本吻合。采用雷诺应力模型和SST物理模型,重点研究了周围两幢超高层建筑对金茂大厦静力风干扰的影响,包括底部总剪力、总弯矩(或扭矩)和有代表性点的平均风压系数,最后结合金茂大厦周围风流动的规律,分析了风环境对金茂大厦干扰影响的原因。

| Abstract: | A precise 3D numerical model of Jinmao mansion is set up.The mean wind pressure coefficients of the representative points on the wall of Jinmao mansion from the simulation results agree with the results of the wind-tunnel experiment.Then using the Reynolds stress model and SST physical model,the key research is on the aerodynamic interference of two high-rise buildings near Jinmao mansion,including the total shearing force at the bottom,the total moment(or torsion)and the mean wind pressure coefficients of the representative points.Finally,the reasons that Jinmao mansion is interfered are further analysed according to the form by which wind flows through Jinmao mansion. |
