Comparison Research of Three Vibration Control Plans on a Super-Tall Building with Connective Structure

Vibration control of a super-tall frame-shell wall building with connective structure is studied in this paper. According to the natural characteristics of the structure, three kinds of vibration control plans with nonlinear viscous dampers are proposed to proceed vibration control in wind action. The fluctuating wind time-series of the structural forward and reverse Y-direction in 10-year frequency are simulated by improved AR model based on Fourier-transform. The structural dynamic responses of different control plans in wind action are studied, and corresponding vibration control effects are analyzed technically. The results show that the structural wind-induced vibration responses can be controlled effectively by the proposed three control plans, the maximum acceleration reduction of 39.2% can be achieved for point 319 of the top story and then structural comfort induced by wind action is improved greatly. Energy of about 30%–40% input by wind-induced vibration can be dissipated by viscous dampers. So, the effectivity and feasibility of nonlinear viscous dampers in reducing wind-induced vibration responses of high-rise or super-tall structures are fully proved.
