Wind-induced vibration of high-rise buildings and its countermeasures

Abstract

This article analyzes the cause of the wind-induced vibration, points out its harm, and finally introduces some countermeasures of it nowadays. To commence, it introduces the phenomenon called Buffeting, Vortex-excited Vibration and Self-excited Vibration that leads to the vibration. Then, it concludes that the vibration will lead to structural damage and make its residents uncomfortable through analyses, indicating that the vibration can be controlled by structural optimizing, aerodynamic measuring and equipping energy dissipation systems. This article simply introduces their principle and application.
