This paper investigated the use of tuned inerter damper (TID) to enhance the seismic performance of dual isolated structure (DIS). An optimization design strategy was developed based on the performance requirements and expressed as a constrained multi-objective optimization design problem, where by the displacement response ratios of isolation layers were adopted as the constraints, and the acceleration response ratio of the superstructure was selected as the objective function. Meanwhile, the time history analysis was conducted to verify the effectiveness of the optimization strategy. The results indicated that the proposed dual isolated structure could effectively decrease the displacement of the superstructure relative to the ground; furthermore, it reduces the isolation layers' deformations compared with the DIS and the base isolated structure (BIS).
