Stochastic Ground Motion Models for Uncertainty Quantification in Earthquake Engineering
Earthquakes are among the most destructive natural hazards, causing significant loss of life and economic damage. Traditionally, seismic risk is computed by combining three conditionally independent components: hazard, vulnerability, and exposure. However, recent advancements in computational power …

Topography effects in the 1999 Athens earthquake : engineering issues in seismology
… motion. Macroseismic observations of destructive earthquakes often show higher damage intensity at the tops of hills, ridges and canyons than at lower elevations and on flat areas. Systematic seismic motion amplification over convex topographies has been confirmed by instrumental studies and also …

Numerical modeling of a bridge system & its application for performance-based earthquake engineering
Many bridges have been damaged during earthquakes. The severity of the recorded damage varies from column failures and bridge deck collapse due to joint unseating to pile and abutment foundation failure due to lateral spreading. In most of these cases, soil pile-structure interaction (SPSI) has …

Bayesian Methods for Intensity Measure and Ground Motion Selection in Performance-Based Earthquake Engineering
The objective of quantitative Performance-Based Earthquake Engineering (PBEE) is designing buildings that meet the specified performance objectives when subjected to an earthquake. One challenge to completely relying upon a PBEE approach in design practice is the open-ended nature of characterizing …

Influence of soil parameters on the motion of rocking walls
Introduced as a system in earthquake engineering in 2004 [6], rocking walls are a fairly new system in earthquake engineering. Their performance has been proven, both in research as in practice. However, a few uncertainties about their behavior still remain. One of these uncertainties is the effect …
