Measuring effective damping of full-scale structure-TMD and TSD systems

Modern tall buildings are often slender, lightweight, and possess low inherent damping, which can lead to excessive wind-induced motion. Dynamic vibration absorbers (DVAs) in the form of tuned mass dampers (TMDs) and tuned sloshing dampers (TSDs) are being commonly employed to increase the effective damping of structures, thereby reducing their resonant responses under wind excitation. While the performance of structure-DVA systems has been …
