摘要：
By integrating the friction pendulum system (FPS) with the tuned mass damper (TMD) atop the highest floor of a high-rise structure, the nonlinear dynamic equation for wind vibration control of the structure was proposed. The induced dynamic equation was solved by the Newmark-β algorithm with internal iteration procedure. The new proposed FPS-TMD system was then assumed to be installed atop the Guangzhou New TV Tower to investigate its wind vibration control efficiency. The effect of different structural parameters of the FPS-TMD system on the wind-induced displacement and acceleration response at the top of the Guangzhou New TV Tower were extensively investigated. These parameters mainly include the damping ratios of the main structure, the mass ratio of the secondary to primary structural systems, the friction coefficients and the radius of sliding chute. Comparing with the wind-induced responses of the original non-controlled structural system, the analyzed results show that more or the most efficiency for the wind-induced vibration control could be obtained by selecting suitable design parameters of the FPS-TMD system. © 2018, Editorial Office of Journal of Vibration and Shock.
