Abstract
To reduce the vibration of tall buildings caused by dynamic loading from wind and ground motions, an active control method is investigated using an active mass damper. An important aspect of active control system design is the amount of control power which must be supplied to the actuator especially in the case of large structures. In this paper, the characteristics of an active mass damper installed on the top floor of a skyscraper is evaluated for the control force and control power under earthquake ground motion and wind. Followingly, the effectiveness of using the band pass filter for loading the relative displacement of an active mass damper is investigated under wind force by using the method of numerical simulation.
