Prediction models and associated uncertainty for dynamic shear modulus and damping ratio of Beijing silty clay [PDF]
Based on experimental data of normalized shear modulus and damping ratio from undisturbed silty clay within 120 m depth in the Beijing area, the Davidenkov backbone curve is used to characterize the normalized shear modulus curve, and the damping ratio ...

Damping Ratio Estimation of Heavily Damped Structures Using State-Space Modal Responses. [PDF]
Vibration control systems are extensively utilized in structures to enhance their resilience against earthquakes and wind forces. However, structures with significant damping exhibit atypical damping behaviors, which impose constraints on the effectiveness of traditional modal analysis methods for discerning modal responses and estimating properties ...

Investigation of the effects of value and modeling approach of natural damping on nonlinear responses of low rise moment-resisting steel frames [PDF]
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 ...
