高层建筑风致振动控制的研究

随着高层以及超高层建筑结构不断向更高和更柔的方向发展,强风作用下这类建筑的传统设计方法有时已经无法完全满足结构的抗风设计要求。因此,提出了采用振动控制来抑制结构风致振动控制的新方法。论文首先概述了高层建筑中风振控制的方法及其国内外的研究现状,然后对其中的调谐质量阻尼器(TMD)、主动调谐质量阻尼器(ATMD),以及摩擦阻尼器这3种控制方法详加评述,最后进一步指出我国风振控制研究的发展方向。

Research of Wind-induced Excitation Control of Tall Buildings

With the structural of tall buildings, as well as ultra-tall buildings, changing to a higher and more flexible direction, the traditional design has been unable to fully meet the requirements for the structure under the strong winds. As a result, the new way, vibration control, in suppressing wind-induced excitation of structures is proposed. First, the paper will outline the methods of wind-induced excitation eontrol of tall buildings and its present situation at home and abroad. Then, three of the controlling ways which are the tuned mass dampers （TMD）, active tuned mass damper （ATMD）, and friction damper will be commented in every detail and particular. FinaUy, the future development ofwind-induced vibration control in China is further pointed out.
