摘　　要：采用MR阻尼器和改进的实时控制程序进行了振动台半主动控制试验。通过与基础固定、基础隔震结构进行对比,验证了该MR阻尼器在瞬时最优、模糊逻辑控制、位移限值控制算法以及零场控制和满场控制的效果,显示了相对于一般基础隔震的优越性。试验结果表明:智能隔震系统不仅能够大幅度减小隔震层的水平位移,有效地保护隔震层和隔震支座,上部结构层间位移反应和加速度反应也得到了有效的控制。采用MR阻尼器的智能隔震系统能够有效地改善隔震结构的性能,大大提高隔震建筑的安全可靠性。A shaking table semi-active smart isolation test is completed in BJUT which is composed of loaded rubber bearings and MR damper with modified real-time control program. At the same time,base fixed and base isolation test are compared with it. Through the experiment,the control efficiency and superiority are illustrated under IOC,FLC,DLC,0A and 2A control with MR damper. The shaking table results indicate that the smart isolation system with ER dampers not only can effectively control the inter-story drift and acceleration but also can limit the base displacement and protect the safety of isolators. The performance of isolated structure is improved greatly,and the experimental and theoretical results could provide references for civil engineering application.
