Abstract:Excessive apex wind vibration acceleration of super high-rise structures can cause discomfort and panic. Using liquid viscous dampers can increase the structural damping ratio, thereby reducing the apex wind vibration acceleration of the structure to achieve the purpose of wind vibration reduction. Related issues in the application of liquid viscous dampers in wind-induced vibration reduction design were discussed, including the comparison of the vibration reduction rates about different arrangements of liquid viscous dampers, the calculation and simulation methods of the damper nonlinear models, and model selection, installation and maintenance of the liquid viscous damping. At the same time, the engineering case shows that the reasonable arrangement of the liquid viscous damper can effectively reduce the apex wind vibration acceleration of super high-rise structure and improve its wind vibration comfort.

Keywords:liquid viscous damper; super high-rise structure; wind vibration acceleration
