中文摘要：

为了改善滑移隔震结构的减震效果和适用范围，提出3种磁流变阻尼器（MRD）与滑移隔震混合方案，建立了MRD与滑移隔震混合控制结构的动力分析模型，对6层MRD与滑移隔震混合控制结构进行地震反应分析。MRD与滑移隔震混合结构的3种混合方案的相对加速度峰值、相对速度峰值、相对位移峰值和层间剪力峰值分别比滑移隔震结构有不同程度的降低，而混合方案3的控制效果更加明显。在此基础上，建立了MRD与滑移隔震混合结构优化设计模型，采用IHGA程序对结构进行优化设计。结果表明，MRD与滑移隔震混合结构的各项地震反应均得到了更好地控制。

英文摘要：

In order to improve the effect of shock absorption and applied scope of sliding base-isolated structure, three kinds of hybrid projects with the magneto-rhrological damper （MRD） and sliding baseisolation were proposed in the paper. A kinematic differential equation was developed. Seismic response analysis of 6-story program structure with MRD and sliding base-isolation was processed. Compared with sliding base-isolated structure, the peak value of various seismic responses of three hybrid projects with MRD and sliding base-isolation were reduced. Comparison of the results of dynamic analysis shows that various seismic responses of hybrid structure with MRD and sliding base-isolation under various loading conditions get better control than sliding isolated structure; the control effect of the third hybrid project is the best of all. The optimal model for hybrid structure with MRD and sliding base-isolation is set up. The various earthquake responses of program structure with MRD and sliding base-isolation get better control after it is optimized with IHGA.
