Reflections on the Hysteretic Damping Model [PDF]

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 ...

Applicability of Time Domain Transform Methods for Frequency Dependent Dynamic Stiffness

Frontiers in Built Environment, 2022
Some types of dynamic stiffness, such as the dynamic ground stiffness used in soil-structure interaction analyses and the viscoelastic body used in vibration control systems, have strong frequency dependency.

Application of extended Rayleigh damping model to 3D frame analysis

Japan Architectural Review, 2023
Rayleigh damping is commonly used in response history analysis (RHA) to provide an energy dissipation source, but the adaptation may be difficult if frequency independence damping is desired over a wide frequency range.

Frequency-independent damping models for a high-rise building with simultaneous horizontal and vertical seismic motions

Frontiers in Built Environment
Recent seismic analyses indicate that the structural damping ratio should be considered frequency-independent, for safe and accurate estimations. In response, damping models like the Wilson–Penzien (WP) damping model, that is one of the modal damping ...

Nonlinear Earthquake Response Analysis Using Causal Hysteretic Damping and Extended Rayleigh Damping

Journal of Physics: Conference Series
Abstract In dynamic design, damping considerably influences the response of structures, so it must be set appropriately. Stiffness-proportional damping is generally used as an inherent damping model, but this model tends to overestimate the damping of higher-order modes. Certain models can evaluate the damping of higher-order modes, such
