Damping modification factors for acceleration response spectra

open access: yesGeodesy and Geodynamics, 2017
DMF (Damping modification factors) are used to modify elastic response spectral values corresponding to damping ratio 5% to other damping levels. The influence of seismological parameters (magnitude, epicentral distances and site conditions) on DMF for ...

Study on the influence of the seafloor soft soil layer on seismic ground motion [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2021
In the complex medium system of the sea area, the overlying seawater and the surface soft soil have a significant impact on the seafloor ground motion, which brings great seismic risk to the safety of offshore-engineering structures.
