摘　　要：高频测力天平风洞试验是确定风荷载最常用的试验方法之一,这项试验技术可以在方案设计阶段的建筑选型上应用,但常被大多数设计师所忽视。本文介绍了风洞试验在超高层建筑外形气动优化的工程案例,相关方法可供类似风效应显著的项目进行参考。通过早期风洞试验,可以在建筑方案设计阶段定量比较不同建筑外形方案的风荷载,特别是能定量研究各种气动优化措施的效果。风洞试验结果可以为建筑师、业主和结构工程师提供设计及决策参考。High-frequency Force Balance( HFFB) wind tunnel test is one of the most commonly used methods in determining wind-induced loads and responses of high-rise buildings. The above test could also be adopted for building aerodynamic optimization in schematic design stage but is overlooked by most designers. This paper presents a practical application example of wind tunnel test on building aerodynamic optimization for a super high-rise building project. The current work provides a good reference of wind tunnel test application on wind-sensitive building projects. The wind loads on different building shapes,with the effects of aerodynamic optimization measures,have been quantified through the experimental test. The current wind tunnel test results provide a design and decision-making reference for architects, owners and structural engineers.
