Pounding between adjacent buildings subjected to ground motion excitation is one of the most dangerous phenomena for building safety. In this paper, three novel configurations are proposed (two of them are uncoupled, and one of them is coupled), and two different passive devices are used, namely, tuned mass damper inerter (TMDI) and tuned inerter damper (TID). In addition, the proposed configurations are investigated for pounding mitigation. To determine the devices’ optimum parameters (mass, inertance, stiffness, and damping), a particle swarm optimization algorithm is used. The objective function is set to minimize the peak of the frequency response functions of interstory drift. The proposed configurations are compared with the best existing configuration in the literature. A large set of ground motion records is used to illustrate the efficiency of the proposed configurations. Based on the results, it is found that the proposed uncoupled configurations by using TMDIs or TIDs perform better than the existing configuration in the literature.
