Performance of Tuned Mass Damper/Double Skin Façade Damping Interaction Systems
Tuned mass dampers (TMDs) can provide very effective solutions for wind-induced vibrations of tall buildings. However, TMDs are usually very large and located near the top of tall buildings for their effective performance. As a result, very valuable occupiable space near the top of tall buildings is sacrificed to contain large TMDs. In addition, installing TMD systems means adding additional masses to tall buildings. As the uses of double skin façade (DSF) systems are increased for tall buildings, this paper investigates an integrated damping system using both TMDs and DSF system that is designed to interact with the TMDs to reduce TMD-related design issues. Compared to the conventional TMD system, the TMD/DSF interaction system requires a significantly reduced TMD mass ratio to achieve the same target damping ratio.
