Modeling, Analysis, and Design of Soil-Structure Interaction Systems

Introduction

This research focuses on advancing in response sensitivity, probabilistic response, and reliability analyses of structural and geotechnical systems. These developments are integrated into general-purpose nonlinear finite element (FE) software frameworks and provide the structural engineers with analytical and computational tools to propagate uncertainties through advanced large-scale nonlinear simulations and obtain probabilistic estimates of the predicted system response performance. The study is also extended to determining the effects of geometric and mechanical parameters characterizing the soil-structure interaction developed in a buried pipe installation located under roads/highways, as well as investigating the adequacy of the coupling factor approach to shallow-buried or near-surface detonations.
