Abstract
With the acceleration of urbanization and the increasing scarcity of land resources, super-tall buildings have become an essential component of modern urban construction. However, the vibration issue of their structures under wind loads has become increasingly prominent, directly affecting the safety and comfort of buildings. To address this, this study systematically investigates the wind-induced vibration response of super-tall building structures, aiming to explore effective analytical methods and control strategies. A combination of numerical simulation and experimental validation is employed in the research. Computational Fluid Dynamics (CFD) technology is utilized to conduct detailed simulations of the wind field characteristics around buildings, while a wind-induced response analysis model is established based on stochastic vibration theory. Additionally, Active Mass Dampers (AMD) are introduced as a control measure, with controller parameters designed through optimization algorithms. The results indicate that the proposed wind field simulation method can accurately capture aerodynamic characteristics under complex wind environments, and the stochastic vibration model can efficiently predict the wind-induced responses of super-tall buildings. Furthermore, the application of the AMD system significantly reduces the acceleration response and displacement amplitude at critical structural locations, thereby enhancing the overall performance of the building. This study not only provides reliable numerical tools for wind-induced vibration analysis of super-tall buildings but also offers significant reference for engineering practice through the optimization design of control strategies. Its innovation lies in the organic integration of high-precision wind field simulation and active control technology, achieving effective suppression of wind-induced responses and substantial improvement of structural performance.
