“…TID has been attracting considerable interest because it has great vibration control performance with small mass and compact configuration. A number of literatures [12][13][14][15] have investigated the efficiency of TID for vibration control of cables. Hu et al 16,17 investigated the optimal design and evaluated the performances of various inerter-based dynamic vibration absorbers and isolators including the TID and TVMD.…”

In this study, the influences of the installation of inerter-based dampers (IBDs) on each modal response, IBDs stroke, inerter stroke, and control force produced by IBDs are derived analytically. A new installation scheme to implement the two ends of the IBDs across multiple storeys, i.e., span-storey installation, is proposed to enhance the control performance of IBDs. The paper starts with a single degrees of freedom (SDOF) system with IBD, and optimal parameters formulas of IBD based on H 2 criterion are obtained. Then the multiple degrees of freedom (MDOF) system with the span-storey installed IBD is analyzed, and an optimization design method is proposed for the new installation method. The proposed design method of span-storey installed IBDs can reuse the design formulas in SDOF case and can reduce response of target modal. A 3-storey benchmark building model is selected as case study, and the results reveal that IBDs with new installation method outperform tuned mass damper (TMD) and the span-storey installation of IBDs is beneficial for control of first modal. Also, the proposed method is validated by the sensitivity analysis and impulse response analysis in case study. Besides, through the comparison of span-storey mounting strategy and increasing inertance strategy, one finds that the span-storey installation of IBDs can substantially improve the efficiency of inerter and damper and reduce the control force by amplifying the drift. Through the simulation on a 9-storey nonlinear benchmark building, the span-storey installed IBDs are found to possess high efficiency in seismic control and can significant reduce the building damage during earthquake.

“…Then Chen et al 30 introduced the TID to the car suspension system, in which the performance of suspension system and ride comfort were effectively improved and the dynamic load to the tire was reduced. In addition, the TID can also be used to control cable vibration 31,32 . However, these vibration absorbers need precise tuning, which is difficult to realize in practice.…”

Summary This paper studies the use of a new nonlinear damper, the hysteretic friction tuned inerter damper (HFTID), for seismic control of engineering structures. The HFTID consists of a tuned inerter damper (TID) in parallel with a hysteresis spring friction element. The analytical expressions for the force and displacement transmissibility of a SDOF system with HFTID are derived via the method of harmonic balance, and the solutions are validated through numerical simulation based on the OpenSees. Parametric study is carried out to investigate the influence of the hysteresis spring friction element on the transmissibility. The optimal tuning parameters of HFTID are obtained and optimality corresponds to minimization of the maximum force or displacement transmissibility. By applying a sequence of curve fitting scheme, design formula for optimal tuning parameters of the HFTID are formulated, which are expressed as functions of structural damping ratio, inertance–mass ratio, and stiffness ratio. The vibration reduction effect and robustness of vibration control systems with HFTID and TID are compared. The results demonstrate that the HFTID can further reduce the transmissibility of vibration control system compared with TID. Moreover, HFTID is more robust than the TID in the case of detuning. Finally, a multi‐story building is taken as an example to demonstrate the effectiveness and practicability of the HFTID in reducing seismic response.

“…By using mechanical amplification mechanisms (such as ball screws, gears, and lever pendulums), inertial devices can provide a larger apparent mass, and inertial force is gradually used for structural vibration control. Lazar et al [26][27][28] replaced the mass part of a tuned mass damper with an inertial mass and constructed a tuned inertial damper (TID). Vibration control analysis of the cable's first vibration mode showed that the TID makes the cable obtain a higher mode damping ratio than the traditional viscous damper.…”

As an essential component of offshore bridges, stay cables are prone to vibrations due to their low inherent damping characteristics. Various dampers have been used for cable vibration control; however, the experimental research and theoretical study of inertial dampers on real cables have not been conducted sufficiently. This study aims to investigate the damping performance of a novel viscous inertial damper (VID) and focuses on the frequency-dependent and displacement amplification phenomena of a cable-damper system. Tests were first conducted to verify the energy consumption capacity of a prototype damper. A shallow cable-VID system was established. Theoretically, complex-valued modes were analyzed to determine the influence of the inertial and viscous coefficients on the cable’s frequency and mode damping ratio. The test results and numerical analysis show that the VID has a good damping effect on the shallow cable. Considering multiple adjacent cable modes, the inertial and viscous coefficients can be optimized. After optimizing, the VID can simultaneously maximize both adjacent symmetric and antisymmetric modes’ damping ratios. The two frequencies are almost the same. The displacement amplification of the VID shows that a VID can overcome the shortcomings of displacement loss caused by traditional oil dampers. The implications of these findings of the VID on shallow cable are discussed, which will guide future research and applications of the VID or other inerter dampers.
