摘要

摘要: 现代城市中相邻结构大量的出现，这样就有可能导致地震中建筑碰撞破坏的加剧。针对安装了AVSD控制器与安装了MR阻尼器的相邻结构半主动控制体系，运用Matlab编程仿真分析了El-Centro波、Taft波和Northridge波三种地震激励下控制效果。结果表明:对相邻结构中较高结构的控制AVSD系统的控制效果较好，但是对其中较低结构的控制MR阻尼器明显优于AVSD系统；AVSD系统和MR阻尼器都可以很好地减小相邻结构的相对位移和相对速度的最大值，从而可以增大相邻结构的间距，减小碰撞破坏的几率，MR阻尼器对相对速度的控制要明显的优于AVSD系统。

Abstract: Architectures in modern cities are built closely or designed as master-slave structure with multisubstructures because of intensity in utilization of land，functions of use and architectural shapes. The architectures with such designs will be damaged worse in earthquake. AVSD control device possesses the advantages of AVS control device as well as those of AVD control device，MR damper has a promising application prospect because of its advanced technology feature. The simulation analysis on semi-active control of seismic responses of adjacent structures connected by AVSD control devices and MR damper was studied when El-Centro wave，Taft wave and Northridge wave were input，good control results were obtained based on the semi-active control law. The control effectiveness comparison between MR damper and AVSD device was analyzed.
