“…All these three systems, the TMD, the TID, and the TMDI, could be installed in multi‐degree‐of‐freedom (MDOF) systems, and due to their setup, they would introduce an additional DOF in the original system. Other configurations involving inerters, such as Ikago et al who introduced a tuned viscous mass damper for civil engineering applications, have been proposed in the literature and are discussed by Zhang et al In addition to the earlier studies demonstrating how TIDs can be designed to improve the behaviour of host structures, such as multistorey buildings or stay cables, TIDs have also been tested experimentally using dynamic substructuring emphasising their feasibility and applicability. Besides civil engineering design applications,() inerter‐based vibration absorbers have been considered in the context of a range of practical applications, such as vehicle suspensions,() train suspensions,() or aircraft landing gears .…”

Summary This paper proposes a novel fully probabilistic framework for the performance‐based seismic design of structures and uses tuned inerter dampers (TID) installed in civil engineering structures subjected to seismic loads to illustrate its applicability. The framework proposed is based on stochastic reduced‐order models, which makes it computationally efficient and can be used for the design of TIDs installed in any complex nonlinear structures subjected to general nonstationary, non‐Gaussian stochastic processes. In this study, the TID is installed in a multi‐degree‐of‐freedom nonlinear structure that is subjected to synthetic seismic records. Numerical results show that the framework proposed is able to provide rigorous and robust values for the parameters of the TID. The design parameters obtained using the stochastic framework proposed are compared with benchmark deterministic approaches, tested also for a large data set of ground‐motion real records. It is shown that the stochastic approach provides insightful designs of the TID that are consistent with the site seismicity and the frequency content of the stochastic excitation.

“…Since its first appearance, the inerter has been widely investigated in the literature because of its salient effect of mass amplification. Industrial applications of inerter could be found in the fields of automotive and civil engineering . In theory, the inerter is a linear two‐terminal mechanical device being capable of engendering a resisting force proportional to the relative acceleration of its two nodes.…”

Summary In this paper, two configurations of series double tuned mass damper with inerters (SDTMDI) are investigated: grounded type (G‐SDTMDI) and inserted type (I‐SDTMDI). For the former layout, two inerters relate each tuned mass to the ground, while they are inserted between any two adjacent masses in the latter layout. Implementing on a harmonically forced primary system of single degree of freedom, their optimal design is conducted by using an extended version of fixed points theory. The present study suggests that for a given total tuned mass, the vibration control effect of G‐SDTMDI is solely controlled by the total inertance, because of which one of the two grounded inerters can be removed, and the vibration control performance will not be influenced under the condition that the amount of inertance remains unchanged. Meanwhile, the control effect delivered by I‐SDTMDI is dictated by the inerter relating the primary system and its adjacent tuned mass. Finally, it is analytically and numerically proven that grounded inerters can render the vibration control effect more pronounced, featured by a decreased peak amplitude and an enlarged frequency bandwidth of vibration reduction. The only potential detrimental effect observed is by incorporating an inerter between the host structure and its adjacent tuned mass. In this case, the vibration amplitude of host structure is amplified, and the effective plateau of vibration reduction is narrowed.

“…This device was studied mostly to improve the seismic performance of a single-degree-of-freedom structures, and it proved to outperform other well-known devices. Recently, a TVMD-like device was applied to a steel structure in Japan [26]. Additionally, one can find studies about multiple-degree-of-freedom system with TVMD [27].…”

In this paper, we analyze the dynamics of tuned mass dampers with inerters. In the beginning, we describe the influence of inertance value with respect to the overall mass of the damping device. For further analysis, we pick three practically significant caseseach corresponding to different composition of tuned mass damper inertia. Then, we focus on the effects caused by different types of inerters' nonlinearities. Viscous damping, dry friction and play in the inerter gears influence the dynamics of the tuned mass damper and affect its damping efficiency. Finally, we examine the dynamics of the model that incorporates all of these factors and propose its simplification which is genuine but more convenient. Our results show how to adjust the inerter type and the parameters depending on our needs and intended application. The knowledge on how to model the behavior of tuned mass dampers with inerters will be of practical use to engineers working with mechanical dampers.
