A METHOD FOR DETERMINING RAYLEIGH DAMPING PARAMETERS OF COMPLEX FIELD
Civil Engineering Journal, 2019 Rayleigh damping model, which is still adopted by manygeneral finite element programs and widely used in analysis of engineering, leads to the inconformity of the calculating modal damping ratio with the actual modal ...

Computation of Rayleigh Damping Coefficients for the Seismic Analysis of a Hydro-Powerhouse
Shock and Vibration, 2017 The mass and stiffness of the upper and lower structures of a powerhouse are different. As such, the first two vibration modes mostly indicate the dynamic characteristics of the upper structure, and the precise seismic response of a powerhouse is ...

Numerical Simulation of the Infinite Medium of Dry Soil in Dynamic Soil-Structure Interaction Problems [PDF]
Engineering and Technology Journal, 2013 One of the major issues in the dynamic analysis of soil-structure interaction problems is to model the far field medium. The dynamic analysis of soil-structure interaction problems can be carried out by using a numerical solution procedure such as finite

NON-RIGID KINEMATIC EXCITATION FOR MULTIPLY-SUPPORTED SYSTEM WITH HOMOGENEOUS DAMPING
International Journal for Computational Civil and Structural Engineering, 2018 This paper continues the discussion of linear equations of motion. The author considers non-rigid kinematic excitation for multiply-supported system leading to the deformations in quasi-static response. It turns out that in the equation of motion written

Rayleigh Damping in the Free Troposphere
Journal of the Atmospheric Sciences, 2014 Abstract This paper explores whether cumulus drag (i.e., the damping of winds by convective momentum transport) can be described by an effective Rayleigh drag (i.e., the damping of winds on a constant time scale). Analytical expressions are derived for the damping time scale and descent speed of wind profiles as caused by unorganized ...
