风向和平均风速联合分布是风荷载的基本特征之一，本文研究风向对某超高层建筑等效风荷载的影响．主要包括以下三个部分：（1）获取建筑物所在地区气象站的风向风速气象资料，并统计得到各个风向上的设计风速；（2）对某超高层建筑进行36个风向角下的刚性模型同步测压风洞试验，试验中模拟了周围建筑对超高层建筑的干扰作用：（3）结合各个风向上的设计风速．基于风洞试验结果．用随机风振理论计算超高层建筑的等效风荷载．本文得到的结论为超高层建筑设计提供参考．

The joint distribution of wind velocity and direction is one of prime characters of wind load. The effects of wind direction on equivalent static wind loads of a super wind velocity corresponding to each wind direction was calculated. （2） The pressure measurement test of the building was conducted by using the synchronous multi-pressure scanning system in wind tunnel and surrounding building was simulated in wind tunnel test. （3） The equivalent static wind loads corresponding to each wind direction were calculated based on wind tunnel results and stochastic vibration theory. The conclusions of this paper are useful for the wind-resistant design of high-rise buildings.
