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。
A large number of adjacent structures in modern cities appear, which may lead to aggravating the collision of buildings in the earthquake. Aiming at the semi-active control system of adjacent structures with AVSD controller and MR damper installed, the control effects of the three kinds of seismic excitation of El-Centro wave, Taft wave and Northridge wave are analyzed by Matlab programming. The results show that the control effect of AVSD system with higher structure in adjacent structure is better, but the MR damper with lower structure is obviously better than AVSD system. Both of AVSD system and MR damper can be well reduced The relative displacement and the relative speed of the small adjacent structures are maximum, which can increase the spacing between adjacent structures and reduce the probability of collision damage. The MR damper has better control over the relative speed than the AVSD system.
