ResumoWind tunnel tests were conducted to investigate the effects of some aerodynamic devices on the wind‐induced responses of tall buildings and structures. It was found that the fitting of small fins or vented fins to a square tower caused an increase in the along‐wind response, while reduction in cross‐wind response occurred only for a limited range of reduced wind velocities. The use of slotted corners resulted in significant reductions in both the along‐wind and cross‐wind responses over an extended range of reduced wind velocities. The concept of slotted corners is practical and could be useful in the design of modern tall buildings and structurees.
