Journal ArticleDOI
TL;DR: Considering the SSI effects, an optimization algorithm, such as the simulated annealing algorithm, can be used to obtain design parameters of the inerter system, thereby more effectively reducing the dynamic response of structures equipped with an inerters system.

Journal ArticleDOI
TL;DR: The energy-dissipation-based method is used to analytically explain the discovered benefits of inerter systems including the reduction in input energy and the enhancement of energy dissipation, which further yields optimal design for the inerster systems.

TL;DR: In this article, the authors deal with the dynamic ASPECTS of the sub-subject: MATHEMATICAL ANALYSIS of systems SUBJECTED to INDEPENDENT VIBRATIONS by means of MATHEATICAL MODELS.
Abstract: PART 1 DEALS WITH THE DYNAMIC ASPECTS OF THE SUBJECT: MATHEMATICAL ANALYSIS OF SYSTEMS SUBJECTED TO INDEPENDENT VIBRATIONS BY MEANS OF MATHEMATICAL MODELS. THE ANALYTICAL SYSTEMS USED ARE NON-LINEAR SYSTEMS, HYDRODYNAMICS AND NUMERICAL METHODS. PART 2 EXAMINES SEISMIC MOVEMENTS, THE DYNAMIC BEHAVIOUR OF STRUCTURES AND THE BASIC CONCEPTS OF THE SEISMIC DESIGN OF STRUCTURES.

Journal ArticleDOI
TL;DR: In this paper, the authors proposed a tuned parallel inerter mass system (TPIMS) for wind turbine tower seismic response mitigation, which consists of a tuned mass, a spring, and a parallel in-erter subsystem, of which the spring is used for tuning the mass and the inerters subsystem is set for vibration energy absorbing and dissipation.

Journal ArticleDOI
TL;DR: In this paper, the authors presented a theoretical and numerical study of a structure-TID system subjected to earthquake ground motions, and derived simple design formulas for the TID when it attached to a single-degree-of-freedom (DofF) structure subjected to ground acceleration excitations.
