Summary: This study investigates the stochastic seismic responses of a base-isolated structure (BIS) with an electromagnetic inertial mass damper (EIMD) subjected to seismic excitations. Analytical solutions for the response variances of the BIS-EIMD system are derived, and a parametric study is conducted to investigate the optimal parameters of the EIMD under different soil conditions. Numerical simulations demonstrate that the EIMD is capable of significantly suppressing the seismic responses of the base floor and the superstructure, outperforming conventional viscous dampers.

Summary: This paper investigates the usage of inerter-based passive structural control, specifically in a wind turbine system, for mitigating seismic response. The inerter-based dynamic vibration absorber (IDVA) is employed as the passive control system, where a spring and inerter-based mechanical network are connected in parallel. The study utilizes a multi-degree-of-freedom (MDOF) system to describe the interaction between the wind turbine structure and soil. Different methods are used to design the inerter-based mechanical network as a controller for mitigating seismic response. The results show that the IDVA control can achieve the same tower-top displacement performance as the traditional tuned mass damper (TMD) control with a smaller additional mass ratio. The numerical simulations further demonstrate the superiority of IDVAs over TMDs in reducing tower-top displacement and tower bottom bending moment performance in a 5-MW wind turbine system.

Summary: In this paper, a design framework for inerter-based vibration absorbers (IVA) is extended to multi-storey hysteretic/yielding structures. The framework utilizes a high-fidelity finite element model (FEM) and a reduced order model (ROM) to accurately describe the structural behavior while reducing computational burden. The impact of nonlinear behavior on IVA design and efficiency is evaluated by comparing designs and performance predicted using linear and nonlinear structural models.

Summary: This article proposes a novel vertical Stiff dynamic absorber (SDA) that aims to minimize vertical accelerations induced on the structure and keep the displacement within reasonable limits. The optimized design parameters of the SDA are applicable across a wide range of vertical vibration control applications, achieving great acceleration isolation without compromising the weight-bearing capacity of the structure.

Summary: This study proposes an enhanced dual isolation configuration combined with supplemental inerters to address the drawback of the relative displacement amplification in the dual isolation system. Optimal inertance values of the supplemental inerters have been determined numerically. Time-history analysis demonstrates the advantages of the optimized dual-isolated structure over the original dual-isolated structure and the corresponding base-isolated structure.

Summary: This paper investigates the use of tuned inerter damper (TID) as a passive control device to mitigate excessive vibrations induced by wave and earthquake loads on offshore platforms. An analytical design method is proposed, and the optimal installation location and design parameters are determined by transforming the original multi-degree of freedom system to a single degree of freedom modal system. Numerical simulations and case studies demonstrate the effectiveness of the TID system in reducing platform responses.

Summary: This study investigates the use of novel combinations of true negative stiffness dampers (NSDs) and inerter devices as supplemental dampers for base-isolated structures. The optimal parameters for NSD and three configurations of negative stiffness inerter dampers (NSIDs) are derived using classical H infinity optimization. Numerical searching and comparative analysis are used to verify the effectiveness of the derived parameters. The results show that the optimal NSIDs and NSD effectively control the objective variables of the base-isolated structure, especially under near-fault earthquakes. The proposed supplemental dampers improve energy dissipation capacity and cushion against failure.

Summary: This study proposes a practical and semi-analytical method based on the damping enhancement principle for the design of inerter-controlled multi-degree-of-freedom structures under earthquakes. By distributing the parameters of the inerter systems and minimizing the required damping coefficient, the vibration mitigation efficiency is improved. The analysis results of three benchmark structures demonstrate the effectiveness of the proposed design.

Summary: Inerter-based dampers have been a topic of great interest in earthquake engineering for the last two decades. This paper presents experimental results from shake table tests on a scaled three-storey structure with an inerter-based damper included, exploring the differences between using viscous and hysteretic damping in the damper. The results confirm that the suppression of higher resonance peaks is significantly different between the two types of damping mechanisms.

Summary: This paper addresses the seismic performance of structures with clutch inerter dampers (CID) through a numerical study of single degree of freedom (SDOF) structures. The results show that the CID is typically more effective than comparable viscous dampers and performs similarly across different earthquake types. Further investigation on the use of CID is warranted.

Summary: In recent years, the tuned mass damper inerter (TMDI) has been shown to effectively absorb vibrations and protect non-isolated buildings from seismic events. This paper introduces a new approach that utilizes a nonlinear viscous damper (NVD) in the TMDI for improved seismic response protection. The study includes an optimal tuning method for the nonlinear TMDI, taking into account the absorber's connectivity to the building structure and utilizing statistical linearization to address the nonlinear damping effect. Numerical data and analysis results demonstrate the benefits of using the NVD in the TMDI, such as reduced stroke and inerter force with minimal impact on building drift and acceleration.
