    摘要: This paper investigates the effect of the single and multiple aerodynamic modification mechanisms on the dynamic behaviour of the principal building when it is interfered by a very closely located building. During the study, aeroelastic vibration tests and high-frequency force balance tests are conducted to compare responses and wind forces in a well-simulated turbulent boundary layer flow. The principal building is manufactured with three different building configurations to represent the single and multiple aerodynamic modification treatments; the neighbouring building which produces interference effects is made as a square prism model. Results show that the multiple modification treatment is efficient in reducing wind forces in all interference location series. However, it is also found that in some critical conditions, such treatment is sensitive to reduced velocity and may amplify the interference effect and result in larger displacements.
