Shenzhen Branch, Shenzhen 518048,Abstract: 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.Keywords: High frequency force balance; wind tunnel test; aerodynamic optimization作者简介：赵建光，博士，Email: jian-guang.zhao@arup.com。
