Abstract
Wind‐tunnel tests on an aeroelastic building model with viscoelastic dampers are conducted to investigate the vortex‐induced response of a viscoelastically damped building under uniform flows. Performance of the viscoelastically damped model is compared with that of a viscously damped model simulated by the building model with silicone oil. The damping ratio provided by the viscoelastic damper is varied by changing the temperature of the damper. Dynamic characteristics of the damped model are estimated from free vibration tests. It is observed that the near‐resonance response of the viscoelastically damped model is similar to that of the viscously damped model. The vortex‐induced responses of both models are also similar when the damping ratio is increased to suppress resonant behavior. Test results indicate that, for practical applications of viscoelastic dampers to high‐rise buildings with low added damping ratio, the viscoelastically damped model may be adequately equivalent to a viscously damped model.
