Semi-active control for wind-induced vibration of high-rise structure using MR damper

本文探讨了磁流变阻尼器在高层建筑风振控制中的应用，在经典线性最优控制理论的基础上，根据磁 流变阻尼器的特点，提出了一种新型的半主动控制策略。应用该方法对－４０层的钢结构的风振反应进行了 计算机模拟，结果表明，采用磁流变阻尼器对高层建筑进行半主动控制能够有效减小结构的风振反应。

This paper discusses the application of MR damper in the field of wind-induced vibration control of high - rise structure and puts forward a new semi - active control strategy based on the classical LQR theory and the characteristic of MR damper to prove the method for simulating the wind - induced vibration responses of a 40 - story steel structure by computer. The results illustrate that MR damper using semi - active control algorithm can reduce the structural response induced by wind efficiently.
