Seismic-wave path attenuation and local site responses in eastern Guangdong province revealed by the ground-motion spectral analyses

open access: yesFrontiers in Earth Science, 2023
In an effort to investigate the attenuation characteristics and site effects in eastern Guangdong, 659 strong-motion recordings received by 27 stations were selected for spectral analysis to separate path attenuation, site effects and source spectra. The

Linear site-response characteristics at central and eastern U.S. seismic stations

open access: yesFrontiers in Earth Science, 2023
Earthquake S waves can become trapped, or resonate, between the free surface and high-impedance basal layers, strongly contributing to site response at specific frequencies.

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.
