| 摘 要： | 橡胶垫隔震结构在遭遇大的罕遇地震时，由于隔震层的位移过大，会引起隔震层的破坏．在加入常规被动阻尼器后，隔震层位移得到减小，但上部结构层间位移和加速度将要放大．这个过大的绝对加速度将使结构内部的物品遭到破坏．为此，采用磁流变（躲）阻尼器与普通橡胶隔震支座相结合，采用不同算法和控制策略对结构进行振动控制．振动台试验结果表明，该组合智能隔震系统相对一般被动隔震装置，能同时减IJ~l-部结构加速度和隔震层位移． |

| Abstract: | The isolation structure with rubber bearings has too large displacement of isolation layer when it is subjected to rarely occurred earthquake,which causes the failure of isolation layer.When some passive dampers are located in the structure,displacement of isolation layer reduces,but layer drift displacement and absolute acceleration of superstructure magnify.This overlarge acceleration results in damage of facilities in the structure.Therefore smart-based isolation system combined with rubber bearing and magnetorheological(MR) damper is applied to structural vibration control.The system employs different algorithms and control strategies.Shaking table test results indicate that the combined smart isolation system,compared with passive isolation equipment,can reduce acceleration of superstructure and displacement of isolation layer. |
| Keywords: | smart isolation system rnagnetorheological damper shaking table test vibration control |
