摘要
本文介绍了AVS/D半主动控制系统的工作原理,参照现行抗震设计规范的设计思想,提出了AVS/D半主动控振结构的抗震设计方法,并针对具体结构控制系统的工作性能,探讨了结构设计中关键参数:主体结构的地震力折减系数和薄弱层层间位移相对控制率的确定方法,最后通过实例分析验证了该方法的可行性。
This paper is an introduction to the working theory of active variable stiffness/damper(abbreviated to AVS/D) semi-active control system according to the ideas of current seismic design code.A seismic design method of structure with AVS/D semi-active control system is proposed.From the working performance of objective control system,the determination method of pivotal parameter for the reducing ratio of the earthquake action of structure and the relative control ratio of the interstory drift in the thinner story are presented.An example is given in the end of this paper.
