摘要：

Track nonlinear energy sink (NES), a type of passive structural control device effective in a wide range of frequency, is introduced in the paper. Shaking table experimental investigation of a five-story frame structure coupled with a track NES are conducted by inputting white-noises. The results show that the track NES is capable of reducing the structural responses in multiple modes. NES can be applied to wind-induced vibration control of high-rise buildings due to this advantage. The AR linear regression method is applied to generate the wind velocity time histories at different heights. Under the wind excitations, parameters of a track NES including the mass, track express and damping, are optimized to reduce the acceleration responses of a high-rise building to which the track NES is attached. The simulated results show that with proper parameters, the track NES is able to attenuate the wind-induced vibration efficiently. © 2016, Nanjing Univ. of Aeronautics an Astronautics.
