“…The proportional coefficient is called inertance, the unit of which is kilogram. Nowadays, the inerter has been applied in various mechanical systems, such as suspension systems [2,3] and so on [4][5][6][7][8][9]. An inerter has better vibration reduction effects than a mass that is as heavy as the inerter [1].…”

In this paper, a lever structure is proposed to enlarge the range of inertances of existing semiactive inerters. A semiactive inerter with the lever structure would be called lever-based semiactive inerter. The transmission ratio of the lever-based semiactive inerter can be changed by setting a different ratio of the arm of force of the lever, and then the range of inertance of the lever-based semiactive inerter can be enlarged. This paper also presents the mechanical model of the proposed lever-based semiactive inerter. The lever-based semiactive inerter is applied to an adaptive tuned vibration absorber. The frequency-tracker-based control algorithm is derived to maximize vibration reduction of the absorber. It can be shown that the vibration absorber with the lever-based semiactive inerter can adapt to a broader range of frequencies of vibration compared with that of the classical semiactive inerter.

It is realized that force exerted at the two ends of an inerter is proportional to their relative acceleration between them. Generally, a mechanical inerter has much smaller mass than a conventional mass damper when identical inertial force is attained due to its mechanical characteristics. In this study, a novel active control system named active inerter damper (AID) is proposed to mitigate seismic response of buildings which is composed of a mechanical ball-screw inerter, a servo-hydraulic actuator, sensors, and a digital controller.Compared to an active mass damper, the AID requires less mass support structure and installation space in real engineering practice. In this paper, two force tracking controllers for the AID system are proposed, designed, and validated in the laboratory first which aim to impose control force on buildings accurately because force tracking performance of an active control system is extremely crucial to its seismic control performance. Afterwards, shake table tests of a three-story steel specimen with an AID system are conducted to validate the feasibility of AID control application for buildings. The control force is computed from a machine learning-based controller that utilizes acceleration feedback directly from the steel specimen. Experimental results demonstrate that force tracking performance of the AID system is satisfactory. Meanwhile, the AID system mitigates seismic response of the steel specimen successfully and effectively.

“…This unique characteristic is advantageous in vibration control. IVAs can be grouped into inerter-based energy dissipators (EDs), inerter-based dynamic vibration absorbers (DVAs), and inerter-based vibration isolators (Ma et al, 2021). Inertial mass dampers (IMDs) are inerter-springdamper setups that are used instead of standard springdamper arrangements in inerter-based EDs.…”

Passive energy dissipation devices or supplemental damping devices have been successfully implemented into structures for controlling the excessive vibrations under wind and seismic excitation. Recent developments in the form of negative stiffness dampers (NSDs) and inerter-based vibration absorbers (IVAs) as potential energy dissipation devices are of considerable interest to researchers. The present study evaluates the performance of the combined NSD and IVA as a possible alternative to the traditional energy dissipation devices such as viscous dampers (VDs) and viscoelastic dampers (VEDs). The mathematical formulation and optimal design of the combined NSD and IVA mechanism are presented. A 20-storey benchmark building is modeled as a multi-degree-of-freedom (MDOF) shear building. The dynamic equations for the MDOF building are written in the state-space form, and a simple optimization approach based on effective modal damping is prescribed. Comparative performance between traditionally applied and novel IVA and NSD is investigated. The design considerations to analyze structures employing combined NSDs and IVAs are developed. It is demonstrated that NSDs and IVA-based passive energy dissipation devices are the most efficient devices in reducing inter-storey drifts and floor accelerations compared with VDs and VEDs using the same damping coefficient.
