Abstract
Recently, much reasearch has been done in projects seeking to dampen wind or earthquake induced vibration of tall buildings. Our particular reasearch involves the Active Mass Damper (AMD) System. This paper describes an AMD system developed for an actual structure using an electro-hydraulic servo mechanism, which controls torsional and translational vibration of the structure concurrently. The system makes use of two 36 ton AMD masses which are controlled using a single digital controller that implements optimal control theory. Following installation of the system on the building, experimental result showed the effectiveness of the system. This paper shows both simulation and experimental results.
