Comparative Analysis of Viscous Damping Model and Hysteretic Damping Model
Applied Sciences (Switzerland), 2022 A damping model is one of the key factors in dynamic analysis. Viscous damping and hysteretic damping models are commonly used in structural damping models.

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.
