Abstract This paper presents the effectiveness of wall-type viscous dampers for controlling of wind-induced vibrations of a high-rise building. A five-stroy experimental building model, square in plan, was designed and constructed for investigation of effectiveness of wall-type viscous dampers in the wind tunnel. This paper describes the physical modelling, its instrumentation, experimental set-up, damping mechanism, and methodology. The effectiveness of wall-type viscous dampers in attenuating vibratons was investigated for different fluid levels in the walls and at varying wind speeds and attack angles. Wind-tunnel results show that wall-type viscous dampers are highly effective in reducing wind-induced vibrations and in wide band of exciting frequency.
