【提要】 风荷载是强风区高层建筑的主要侧向控制荷载，确定脉动风荷载是高层建筑结构设计的需要。借助于高频动态天平试验和风压测量试验，分析讨论了沿建筑物高度分布的平均风力、脉动风力、风致振动惯性力以及建筑结构设计所需要的等效静态风荷载的确定问题，可为高层建筑结构设计中的风荷载确定提供参考。

Determination of Equivalent Static Wind Load on Highrise Building/Li Huizhi,Fan Youjing(College of Civil Engineering,Zhengzhou University,Zhengzhou 450002,China)
Abstract:Determination of fluctuating wind loads is necessity to highrise building design.The height distributions of the mean wind force,fluctuating wind force,wind induced vibrating inertial force,and the determination of the equivalent static wind load needed for the structural design of the buildings are researched based on a wind pressure test and a high frequency balance test.The results can be used as a reference for determining the wind load of highrise structure.
