Abstract
This article introduces a new method, active flow field control through steady suction, to reduce wind loads on buildings. To test its effect, suction equipment was developed and installed on a Commonwealth Advisory Aeronautical Research Council super high-rise model. A series of experiments were then conducted in a wind tunnel. The effectiveness of this method for reducing wind loads is discussed through comparison of the suction bottom moment ratio under different wind incidence angles and different positions of steady suction. The results of the experiment demonstrate that steady suction reduces wind loads effectively.
