Near-Resonance Behavior of a Visco-Elastically Damped Building Model Under Uniform Flow

摘要

This paper discusses the wind vibration control for a tall building using passive control dampers. Viscous damper and viscoelastic damper are considered in this study, and they are attached to a wind tunnel test model. The test set-up includes a special measurement system to obtain the damper hysteresis loop, which is extremely useful to understand the dynamic characteristics of the dampers and the model. Free vibration tests as well as wind vibration tests using uniform flow are conducted with or without the dampers. The model global response is correlated with the damper local response. Commonality of the damper responses obtained from the free vibration test and the wind tunnel test is discussed.
