STRUCTURAL CONTROL USING ACTIVE TUNED MASS DAMPERS

Abstract

Passive tuned mass dampers (TMD) are being using for motion control of tall buildings. The possibility of enhancing TMD effectiveness in structural with added active control capability is studied in this paper. The problem of structural control using active TMD is fromulated using classical feedback control theory. Using simple numerical examples, it is shown that an addition of active control forces to TMD systems can lead to significant improvement in displacement and acceleration reductions. Furthermore, TMD stroke requirement can also be significantly reduced with added active control element.
