Abstract:Aiming at the parameter design of viscous dampers in the wind resistance design of the super high-rise structures, the power calculation expression and the power demand expression of the viscous dampers were deduced, and the amplification coefficient of storey drift of the viscous damper was studied. Power design method for controlling wind-induced vibration of super high-rise structures with viscous dampers was provided. Taking two super high-rise structures as an example, the power design flow of the viscous dampers for controlling the wind-induced vibration of super high-rise structures were realized step by step. The feasibility and error of the design method were analyzed. The results show that the preliminary design of energy-dissipation based on power design method can achieve the desired vibration reduction target.
Keywords:super high\|rise structure; viscous damper; power design; wind-induced vibration control
