Evaluation of Site Response Analysis for Vertical Ground Motions in LS-DYNA Using Geotechnical Downhole
… Current practice for predicting vertical ground motion is to use the V/H method, which is not site specific. This method utilized measured vertical to horizontal (noise or earthquake) spectral ratios to convert ground motion prediction equation outputs to the vertical direction. The final …

A Predictive Modeling Approach for Assessing Seismic Soil Liquefaction Potential Using CPT Data
… mirrors the random/mixed effects models used in ground motion prediction equation development. The model is tested using an independent set of case histories from recent New Zealand earthquakes, and performance metrics are reported. </p> <p>We found that a Bayesian measurement error model …

Ground Motion Prediction Equations for Non-Spectral Parameters using the KiK-net Database
The KiK-net ground motion database is used to develop ground motion prediction equations for Arias Intensity (I<sub>a</sub>), 5-95% Significant Duration (Ds<sub>5-95</sub>), and 5-75% Significant Duration (Ds<sub>5-75</sub>). Relationships are developed both for shallow crustal earthquakes and …

Seismic Slope Stability: A Comparison Study of Empirical Predictive Methods with the Finite Element Method
… the slope is subjected to 88 different input motions, and the seismic displacements obtained from the numerical and empirical approaches are compared statistically. From correlation analyses between seven ground motion parameters and the numerical results, new empirical predictive equations …

Topographic Effects in Strong Ground Motion
Ground motions from earthquakes are known to be affected by earth's surface topography. Topographic effects are a result of several physical phenomena such as the focusing or defocusing of seismic waves reflected from a topographic feature and the interference between direct and diffracted seismic …

Partitioning Uncertainty for Non-Ergodic Probabilistic Seismic Hazard Analyses
… accounting for the uncertainties in predicting ground motion parameters is critical for Probabilistic Seismic Hazard Analyses (PSHA). This is particularly important for critical facilities that are designed for long return period motions. Non-ergodic PSHA is a framework that allows for this …

Uncertainty Quantification in Earth System Models Using Polynomial Chaos Expansions
… location plays a dominant role in earthquake ground motion responses (in terms of peak ground velocities, PGVs), while elliptical patch properties only show secondary influence. In addition, Our PC based Bayesian analysis successfully identified the most `likely' fault plane configuration with …

Regionally adaptable ground-motion Prediction Equations (GMPEs) for seismic hazard analysis
Adjustment of empirically derived ground motion prediction equations (GMPEs), from a data- rich region/site where they have been derived to a data-poor region/site, is one of the major challenges associated with the current practice of seismic hazard analysis. Due to the fre- quent use in …
