摘要：
Taking Beijing Olympic Tower as the engineering background, the vibration control properties using viscous dampers, which are aimed to improve the human comfort, were investigated. Both haunched corridors scheme and unhaunched corridors scheme were designed according to the structural characteristics of the multi-tower structure, and their dynamic characteristics were compared. Then the viscous fluid dampers (VFDs) were introduced into the unhaunched corridors scheme, and the position, amount and other parameters of these dampers were optimally designed to develop a structural control scheme. A three-dimensional wind field of the structure was generated from wind tunnel data, and the wind-induced responses of the aforementioned three schemes were analyzed. The results were analyzed in terms of space distribution of responses, influences by wind angles, time and frequency characteristics and damper outputs. The results show that the peak acceleration responses of both the haunched corridors scheme and the structural control scheme are reduced compared with the unhaunched corridors scheme, and the maximum reduction of the structural control scheme reaches 30.28%. © 2021, Editorial Office of Journal of Building Structures.
