| 摘 要： | 珠江城商务写字楼高309.6m,在大楼中上部安装有4个风能发电机进行风能发电,风荷载是该超高层建筑的控制荷载。对该建筑进行了大比例尺(1∶150)模型的风洞试验,根据试验结果计算了该结构的基底等效风荷载,分析了吸风口附近和各立面风压分布的特点、吸风口内风速放大的特点以及高层建筑中应用风能发电的可行性,并将基底等效风荷载与小比例尺模型的风洞试验结果进行了对比。结果表明:根据不同比例尺模型的风洞试验结果计算的基底等效风荷载会有所不同;在超高层建筑中开设吸风口应用风能发电,对减少结构总体风荷载是有益的,但风机运行时,吸风口内测点极小值风压比无风机时最大增加65%。在超高层建筑中应用风能发电是一种开创性的策略,在超高层建筑中可获得比10m高度处大29.5倍的风能,但要充分利用高层建筑进行风能发电需进行深入研究。
