The seismic performance evaluation of two adjacent single-degree-of-freedom structures (SDOF) connected with a novel negative stiffness-inerter-based damper (NSID), tuned inerter damper (TID) and viscous damper (VD) is studied under base excitation. The two SDOF structures are typical of adjacent bridge structures that are vulnerable to pounding during strong seismic activity. The base excitation is modelled as a stationary white noise random process. The equations of motion are written in state space form, and optimal parameters for maximum possible response reduction are evaluated. The optimal parameters are based on minimising the total relative energy of two adjacent structures under white noise base excitations. The optimal parameters obtained for TID and NSID show that adding an inerter to a VD lowers the optimum damping ratio. Also, adding negative stiffness to TID further lowers the optimum inertance and damping ratio. The performance of optimised dampers connecting adjacent SDOF systems is then assessed under real earthquake records. Numerical results indicate that NSID and TID can achieve similar or even better response reduction than VD using a smaller damping coefficient. Among the two connected systems, more flexible ones show higher response reduction. The analytical study demonstrates that the effective damping of viscous dampers can be enhanced by adding the negative stiffness and inerter elements to the dashpot.

“…Therefore, to overcome this situation without affecting the static mass of the damper, recently, inerter (Smith, 2020) and inertial amplifiers (IA) Yilmaz et al, 2007) have started applying to the TMD to amplify the dampers’ effective mass, resulting in an increment in the dynamic response reduction capacity (Smith, 2020; Pietrosanti et al, 2017). Hence, the inerter-based (Petrini et al, 2020; Wagg, 2021) vibration absorbers (Chen and Hu, 2019b) are applied to mitigate the dynamic responses of the mechanical engineering machinery (De Domenico et al, 2019) and parts, notably automotive and train suspensions (Shen et al, 2016; Wang et al, 2006), buildings (Chowdhury et al, 2022b), wind turbines (Hu et al, 2018; Zhang and Fitzgerald, 2020; Zhang et al, 2019; Zhang and Høeg, 2021), and bridges (Song et al (2021); Liang et al (2021)). There are different types of inerter-inspired (Chowdhury and Banerjee, 2022a) TMD which were developed, such as tuned mass damper inerter (De Domenico and Ricciardi, 2018a; Su et al, 2022), tuned inerter damper (Shen et al, 2019; Wang et al, 2021), tuned viscous mass damper (Ma et al, 2021; Ikago et al, 2012), inerter-based dynamic vibration absorber (Hu and Chen, 2015), angular mass damper (Pradono et al, 2008), gyro-mass dampers (Hessabi and Mercan, 2016), rotational inertia viscous damper (Javidialesaadi and Wierschem, 2019a), viscous inertial mass damper (Lu et al, 2021), electromagnetic inertial mass dampers (Nakamura et al, 2014), rotational inertia dampers (Hwang et al, 2007), clutching inerter damper (Wang and Sun, 2018), tuned inertial mass electromagnetic transducers (Asai et al, 2018), spring-dashpot-inerter (Basili et al, 2019), rotational inertial double tuned mass dampers (Javidialesaadi and Wierschem, 2018), tuned heave plate inerter (Ma et al, 2018), inerter-enhanced nonlinear energy sink (Javidialesaadi and Wierschem, 2019b), tuned liquid inerter system (…”

This paper introduces the inertial amplifier viscoelastic tuned mass dampers (IAVTMD). The viscoelastic materials are implanted inside the core material of the inertial amplifier tuned mass dampers. The standard linear solid models are applied mathematically to formulate the viscoelastic material. H2 and H ∞ optimization mechanisms apply to derive the exact mathematical closed-form formulations for optimal design parameters for novel inertial amplifier viscoelastic tuned mass dampers. The optimum IAVTMD installs at the top of the structures to mitigate the dynamic responses, determining the dynamic responses analytically through transfer function formation. At first, IAVTMD’s dynamic response reduction capacity compares with the conventional tuned mass damper’s (CTMD) dynamic response reduction capacity. As a result, H2 optimized IAVTMD’s dynamic response reduction capacity is significantly 20.87% and 26.47% superior to two well-established H2 optimized conventional tuned mass damper’s dynamic response reduction capacity. In addition, H ∞ optimized IAVTMD has 15.48% more dynamic response reduction capacity than H ∞ conventional tuned mass damper. H2 and H ∞ optimized tuned mass damper inerters with optimal closed-form solutions are introduced in this paper. A higher damper mass ratio and a lower inerter mass ratio are recommended to produce H2 and H ∞ optimized tuned mass damper inerter (TMDI) with a lower frequency and damping ratio in an affordable range. Accordingly, H2 and H ∞ optimized IAVTMD’s dynamic response reduction capacities are significantly 6.94% and 23.29% superior to H2 and H ∞ optimized TMDI’s dynamic response reduction capacity. The closed-form expressions for optimal design parameters of inertial amplifier viscoelastic tuned mass dampers and tuned mass damper inerters are mathematically correct and effective for practical applications.

“…Research on the use of viscous dampers as well as VEDs and VFDs for vibration control of adjacent structures is relatively complete, and scholars are beginning to investigate the application of inerter-based devices to adjacent structures. Lu [27] used viscous inertial mass damper (VIMD) instead of VD to achieve vibration control of adjacent structures considering the apparent mass of the inerter; Song [28] used a TID system to mitigate potential impact and displacement damage between adjacent bridges under seismic effects and compared TID with no control device and VED and VFD in the frequency and time domains; Zhao [29] considered the use of SDI for vibration control of adjacent structures under the left and right of the soil; Lazar [30] proposed a passive control system named TID, which can achieve similar performance with the inerter at the same inertance compared with TMD.…”

In this paper, the effect of viscous dampers (VD) on the control of adjacent structures is firstly discussed, and then the tuned inerter dampers (TID) is utilized to enhance the control performance of adjacent structures. The relative displacement and absolute acceleration responses of the TID controlled adjacent structures are optimized and evaluated by the H∞ performance of the transfer functions. The results show that there is an optimal damping ratio to minimize the displacement response of the adjacent structure when VD is used, but the damping required corresponding to the optimal performance are relatively larger. Instead, the use of TID gradually enhances the control effect with the increase of inertance-mass ratio and the control effect of TID on the structure is more significant at small inertance-mass ratio. Compared with VD, TID only requires smaller damping to achieve a similar performance to VD.
