In this paper, the use of hybrid passive control strategies to mitigate the seismic response of a base-isolated structure is examined. The control performance of three different types of devices used for reducing base displacements of isolated buildings is investigated. Specifically, the Tuned Mass Damper (TMD), the New Tuned Mass Damper (New TMD) and the Tuned Liquid Column Damper (TLCD), each one associated to a Base Isolated structure (BI), have been considered. The seismic induced vibration control of base-isolated structures equipped with the TMD, New TMD or the TLCD is examined and compared with that of the base-isolated system without devices, using real recorded seismic signals as external input. Data show that the New TMD is the most effective in controlling the response of base-isolated structures so that it can be considered as a practical and appealing means to mitigate the dynamic response of base-isolated structures.

“…Recently, a simplified analytical solution for the optimal design of the TMDI for base‐isolated structures has been proposed in Matteo et al, 26 considering an approach based on minimizing the base displacement variance of the base‐isolation subsystem and some simplifying hypotheses such as Gaussian white noise as base excitation, assuming a linear undamped single degree of freedom (SDOF) system to model the base‐isolated structure.…”

“…On this basis, the present study aims to assess the effectiveness of the TMDI in improving the seismic performance of base‐isolated buildings by extending the optimization procedure presented in Matteo et al 26 Specifically, as a first novel contribution of this study, the accuracy of the simplified analytical solution introduced in Matteo et al 26 is investigated by a comparison with a more complex and accurate numerical procedure applied directly to the more general case of a damped multi‐degree‐of‐freedom (MDOF) isolated structure. Moreover, it is worth stressing that in Matteo et al, 26 the seismic performance of a five‐story isolated structure equipped with a TMDI has been analyzed only for two seismic actions. In the present paper, the comparison of the structural responses of the system with and without TMDI is performed considering a set of 44 recorded ground motions as base excitation, with different magnitudes on several soil site classes (both soft and stiff soils are considered).…”

“…Additionally, an inerter is usually connected in series with a stiffness and/or a damper in an isolator. These isolators include, for example, tuned inerter dampers [22], and inerter-based resonant vibration absorbers and isolators [2,23,24].…”

This paper investigates a type of linear vibration isolator which incorporates two passive devices, negative stiffness elements and an inerter, into the conventional isolator (massstiffnessdamper). Two configurations of the passive devices are considered, respectively: (1) the direct parallel connection of the inerter and the negative stiffness element; (2) the series connection of the inerter with the viscous damper, which, together, is then connected with the negative stiffness element in parallel. Numerical evaluations are presented for the isolators subject to base harmonic and shock excitation, in terms of the natural frequency, the displacement transmissibility and shock isolation performance. Compared with other corresponding linear isolators, it is found that in the majority of the excitation situations, the presented isolator with the second configuration has a better performance for some isolator parameter values, that is, the inertance-to-mass ratio, the ratio of negative to positive stiffness and the damping coefficient ratio of the two dampers.
