| Abstract: |
| 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 base-isolation 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. |
