Characterization of forward-directivity ground motions in the near-fault region
TL;DR: In this article, a simplified parameterization is proposed based on a representative amplitude, pulse period, and number of significant pulses in the velocity-time history to estimate the peak ground velocity and period of the velocity pulse (Tv) of available forward-directivity motions.
Journal ArticleDOI
Simplified Procedure for Estimating Earthquake-Induced Deviatoric Slope Displacements
TL;DR: In this article, a semi-empirical predictive relationship for estimating permanent displacements due to earthquake-induced deviatoric deformations is presented, which utilizes a nonlinear fully coupled stick-slip sliding block model to capture the dynamic performance of an earth dam, natural slope, compacted earth fill, or municipal solid waste landfill.
Journal ArticleDOI
Simplified Frequency Content Estimates of Earthquake Ground Motions
TL;DR: In this paper, three simplified frequency content parameters are examined: mean period (T m ), predominant period, and smoothed spectral predominant period (SPM) for 306 strong motion recordings from 20 earthquakes in active plate-margin regions.
Journal ArticleDOI
Assessment of the Liquefaction Susceptibility of Fine-Grained Soils
TL;DR: The results of cyclic tests indicate that the Chinese criteria are not reliable for determining the liquefaction susceptibility of fine-grained soils as discussed by the authors, and the plasticity index (PI) is a better indicator of soil susceptibility.

TL;DR: The field of soil liquefaction engineering has evolved into a sub-field in its own right, and engineering assessment and mitigation of seismic soil liquidation hazard is increasingly well addressed in both research and practice as mentioned in this paper.
