摘　　要：该研究通过对配置磁流变(MR)阻尼器的4层框架基础隔震结构进行建模,系统讨论该结构在2种控制策略作用下的隔震性能。结果表明,相较于经典的bang-bang控制策略,采用模糊控制策略能同时降低结构在地震作用下的基底位移与上部结构的加速度响应,从而实现隔震性能的显著提升。In this paper,a four-story frame isolated-structure equipped with magnetorheological(MR)dampers is modeled,and the isolation performance of the structure under different control strategies is discussed.The results show that compared with the classical bang-bang control strategy,the implementation of a fuzzy control strategy can simultaneously reduce both the base displacement and the super structure acceleration response under seismic actions.This leads to a significant enhancement in seismic isolation performance.
