Extended Rayleigh Damping Model [PDF]
Frontiers in Built Environment, 2016 In dynamic analysis, frequency domain analysis can be used if the entire structure is linear. However, time history analysis is generally used if nonlinear elements are present.

Characterization and synthesis of Rayleigh damped elastodynamic networks
Networks and Heterogeneous Media, 2014 We consider damped elastodynamic networks where the damping matrix is assumed to be a non-negative linear combination of the stiffness and mass matrices (also known as Rayleigh or proportional damping).

Geometric Integration of Hamiltonian Systems Perturbed by Rayleigh Damping [PDF]
BIT Numerical Mathematics, 2011 Explicit and semi-explicit geometric integration schemes for dissipative perturbations of Hamiltonian systems are analyzed. The dissipation is characterized by a small parameter $\epsilon$, and the schemes under study preserve the symplectic structure in

Investigation of the effects of value and modeling approach of natural damping on nonlinear responses of low rise moment-resisting steel frames [PDF]
Journal of Structural and Construction Engineering, 2021 Nonlinear time history analysis is recognized as the most appropriate tool for assessing the real behaviour of structures during seismic excitations. Validity rate of obtained results from this analysis significantly depends to the modeling, details and ...

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.

Error Caused by Damping Formulating in Multiple Support Excitation Problems
Applied Sciences, 2020 The effect of multiple support excitation is an important issue in studying large-span structures. Researchers have shown that the damping related terms in the equation of motion can induce errors in the analysis. Wrongly modelling the damping matrix can
