A new nonlinear effective stress method for one-dimensional seismic site response analysis and its validation

open access: yesYantu gongcheng xuebao, 2021
Given modification of earthquake motions due to liquefaction-induced soil softening, the effective stress analysis should be conducted to develop the site-specific design ground motion parameters at liquefiable sites.

Harmonic-Modal Hybrid Reduced Order Model for the Efficient Integration of Non-Linear Soil Dynamics

open access: yesApplied Sciences, 2020
Nonlinear behavior of soils during a seismic event has a predominant role in current site response analysis. Soil response analysis, and more concretely laboratory data, indicate that the stress-strain relationship of soils is nonlinear and exhibits ...

Determination of Site amplification in the Campania-Lucania Region (southern Italy) by comparison of different Site-Response Estimation Techniques [PDF]

open access: yes, 2008
We have applied a non-linear inversion technique to estimate both the earthquake source parameters and site response from a set of microearthquake records acquired by a dense seismic network, in order to provide a simple uniform site classification for ...
