Experimental results of a wind tunnel study in which active control was applied to wind-induced motion of a tall structure are presented. The control consisted of a small appendage situated at the top of the structure. The study represents one of the first active structural control experiments performed in a wind tunnel. The results further demonstrate that the concept of active control may indeed offer a feasible solution for wind-induced structural vibrations in the future.
