Application of viscoelastic dampers system to super high building for control of wind-induced vibration

Taking a super high-rise building as the engineering background, a wind resistant design method of high-rise buildings installed with viscoelastic dampers (VED) is presented in this paper. The mechanical model of VED system and the structure is established through the following steps. Firstly, the typical impulsive wind load is obtained by the impulsive wind simulation program developed by the author. Then, utilizing the iterative dynamical time-history analysis method described in the paper, the responses of the structure with VED subjected to impulsive wind load is obtained. The result shows that the maximal impulsive wind-induced displacement and acceleration could be reduced by 21.4% and 17.9%, respectively. Moreover its interceded displacement could also be significantly reduced. The research indicates that the proposed VED system and method can effectively control the wind-induced response of tall buildings.
