摘　　要：介绍了某超高层双塔中部联通异型建筑风洞试验方法与数据分析,对该超高层复杂结构的风压分布、风压系数及体型系数进行了研究,得到了可供设计使用的等效静风荷载与楼顶峰值加速度。结果表明,风压在建筑物的中上部及立面拐角区域较大,风吸力(负压)要大于风压力(正压),整体上南塔(高度较低)风压小于北塔(高度较高)风压,总的等效静力风荷载主要由平均风荷载控制。研究成果可为该类结构抗风设计及相关研究提供参考依据。The paper presents wind tunnel tests and the experimental data analysis for a super high-rise twintower building with central corridor. The wind pressure distribution,wind pressure coefficient and shape coefficient of the building are studied,and the equivalent static wind load and peak acceleration of the roof are calculated. The results show that the wind pressure in the middle and upper part of the building and the corner of the facade is larger than other positions;the wind pressure of the South Tower is less than that of the North Tower;the wind suction(negative pressure)is greater than the wind pressure(positive pressure)for both towers;and the total equivalent static wind load is mainly controlled by the mean wind load. It could provide reference for wind resistant design and related research of this kind of structure.
