摘      要：The optimal design and effectiveness of three control systems,tuned viscous mass damper(TVMD),tuned inerter damper(TID)and tuned mass damper(TMD),on mitigating the seismic responses of base isolated structures,were systematically ***,the seismic responses of the base isolated structure with each control system under white noise excitation were ***,the structural parameter optimizations of the TVMD,TID and TMD were conducted by using three different *** results show that the three control systems were all effective in minimizing the root mean square value of seismic responses,including the base shear of the BIS,the absolute acceleration of structural SDOF,and the relative displacement between the base isolation floor and the ***,considering the superstructure as a structural MDOF,a series of time history analyses were performed to investigate the effectiveness and activation sensitivity of the three control systems under far field and near fault seismic *** results show that the effectiveness of TID and TMD with optimized parameters on mitigating the seismic responses of base isolated structures increased as the mass ratio increases,and the effectiveness of TID was always better than TMD with the same mass *** TVMD with a lower mass ratio was more efficient in reducing the seismic response than the TID and ***,the TVMD,when compared with TMD and TID,had better activation sensitivity and a smaller stroke.
