The vibration of towers of suspended bridges due to strong wind has been of great concern to scientists and engineers. In this study, attention is given to the vibration control of a tall bridge tower under construction. An active control method is presented based on the lumped model of the bridge tower and the suboptimal control theory. Since the dynamic parameters of the tower differ under different phases of construction, it is necessary to reevaluate the corresponding model, nevertheless, the control strategy is maintained. Three typical construction phases of a bridge tower are considered in this paper. The modeling method and results of the simulation control are presented to illustrate the validity of the proposed method.
