摘要
本文提出了ER/MR智能阻尼器对空间网壳结构地震反应半主动控制的设计计算方法。文中,在推导了ER/MR智能阻尼器杆件有限单元模型的基础上.建立了设置ER/MR智能杆件的网壳结构地震反应的运动方程,应用本文提出的局域半主动控制策略,我们得到了ER/MR智能阻尼器对空间网壳结构地震反应半主动控制的计算方法。工程实例的计算结果表明:ER/MR智能杆件是一种不会失稳的控制装置,在结构上合理布置ER/MR智能杆件和合理选取 ER/MR智能杆件的参数可获得较好的减震效果.
In this paper, a semi-active control design method of ER/MR smart damper for earthquake responses of reticulated shells is presented. By deriving finite element model of the element with ER/MR damper, the vibration equations of reticulated shells are established. Using part semi-active control strategy proposed by the paper, the calculating method of semi-active control for earthquake responses of reticulated shells is obtained. The calculating results indicate that:(1)ER/MR smart damper is a kind of c...
