Wind-Induced Vibration Control and Analysis of Super High-Rise Structure Using Viscous Damping Walls

Abstract:

The wind-induced vibration control and analysis of a super high-rise structure located in the area of strong typhoon with viscous damping walls is introduced. Mechanical properties and design method of viscous damping wall are described, and then the arrangement scheme is put forward. The performances of structure with and without viscous damping walls under the condition of basic wind strength encountered once for 10 years are investigated in detail. The results show that the control scheme can dissipate energy of wind-induced vibration, attenuate structural dynamic response and reduce the mutation of acceleration along height direction effectively. The maximum peak acceleration can be reduced by 23.5% to 0.241m/s2, which meets 0.25m/s2 limit value stated by Technical specification for concrete structures of tall building. Therefore, the arrangement scheme is feasible and effective to control wind-induced vibration and improve structural safety and comfort.
