Abstract

Abstract: Wind-induced vibration control of a super high-rise building was selected as an example in this paper. The dynamic characteristic of wind was introduced. Fluctuating wind-speed time series of both X-direction and Y-direction were simulated by improved AR model. According to natural characteristics of the building, three kinds of damping control plans of added viscous dampers and tuned mass damper(II), added viscous dampers(III), added tuned mass damper(IV) were put forward. Dynamic analysis of wind-induced vibration control for the building in different wind directions and different control plans was studied in once for 10 years, 50 years and 100 years. The control effect of different plans was analyzed in detail. The results show that the control plans of II and III can dissipate energy imported by wind, attenuate dynamic response, reduce mutation of story-acceleration response and inter-story displacement effectively. The maximum roof displacement and acceleration response can be respectively reduced by 33% and 51.4%. So, the control plans is feasible and effective to control wind-induced vibration, improve safety and comfort of structure. Some suggestions of wind-induced vibration control for high-rise buildings are put forward at last.
