Reflections on the Hysteretic Damping Model
Shock and Vibration, 2009 This paper presents a reflection on a recently proposed solution to the problem of the free vibration response with the constant hysteretic damping model, that has been presented in some conferences in recent years, by the author himself and some of his ...

An Inelastic Beam Element with Hysteretic Damping [PDF]
Shock and Vibration, 2008 In this work, an inelastic beam macro‐element that incorporates hysteretic damping is presented. Based on classical theory of plasticity, a Bouc‐Wen type model is utilized that simulates the hysteretic behavior of an inelastic spring element. Using this model, an inelastic nonlinear beam element is formulated based on the appropriate combination of two

Optimal design of a hysteretically damped dynamic vibration absorber
Mechanical Engineering Journal, 2020 In the optimization of dynamic vibration absorbers (DVAs), it is generally assumed that the damping force changes in proportion to the velocity of the object; this damping is called viscous damping.

Finite Element Modelling and Simulation of the Hysteretic Behaviour of Single- and Bi-metal Cantilever Beams using a Modified Non-linear Beta-damping Model [PDF]
Journal of Applied and Computational Mechanics, 2021 This paper explores a novel non-linear hysteresis model obtained from the modification of the conventional Kelvin-Voigt model, to produce a non-viscous hysteretic behaviour that is closer to metal damping. Two case studies are carried out for a vibrating

New expressions to estimate damping in direct displacement baseddesign for special concentrically-braced frames [PDF]
Numerical Methods in Civil Engineering, 2015 Different expressions have been developed to determine damping of structures based on various hysteretic models and ductility levels. Since Slenderness ratio is an important parameter on the hysteretic behavior of special concentrically- braced frames ...

Behaviour Investigation of SMA-Equipped Bar Hysteretic Dampers Using Machine Learning Techniques
Applied Sciences, 2021 Most isolators have numerous displacements due to their low stiffness and damping properties. Accordingly, the supplementary damping systems have vital roles in damping enhancement and lower the isolation system displacement. Nevertheless, in many cases,

Evaluation of effects of hysteretic damping of shape memory alloys on seismic performance of tuned mass damper [PDF]
Journal of Structural and Construction Engineering, 2019 Tuned mass damper is a common tool in passive control, which is used in many structures. However, with all the proper features, its most important functional limitation is the weakness against broad band excitation.
