Vulnerability Assessment for Earthquake Liquefaction–Induced Settlements of an Embankment Using Gaussian Processes
(American Society of Civil Engineers, 2018)The major cause of earthquake damage to an embankment is the liquefaction of the soil foundation that induces ground-level deformations. The aim of this paper is to assess numerically the effect of the liquefaction-induced ... -
Decision Making for Long-Term Pipeline System Repair or Replacement
(American Society of Civil Engineers, 2018)Corrosion is one of the main causes of pipeline failure, which can have large social, economic, and environmental consequences. To mitigate this risk, pipeline operators perform regular inspections and repairs. The results ... -
Factor Analysis to Evaluate Hospital Resilience
(American Society of Civil Engineers, 2018)Health care facilities should be able to quickly adapt to catastrophic events such as natural and human-made disasters. One way to reduce the impacts of extreme events is to enhance a hospital’s resilience. Resilience is ... -
Risk-Based Arch Dam Optimization Using Hybrid Charged System Search
(American Society of Civil Engineers, 2018)In this paper, the failure costs of an arch dam’s optimum shape were investigated, taking into account the interaction between dam, reservoir, foundation, and hydrodynamic effects resulting from seismic loading. Construction, ... -

Risk-Based Policy Optimization for Critical Infrastructure Resilience against a Pandemic Influenza Outbreak
(American Society of Civil Engineers, 2018)Decisions regarding infrastructure resilience are made under uncertainty and involve trade-offs among competing objectives. An effective way of understanding how uncertainties propagate and understanding trade-offs among ... -
Probabilistic Characterization of Site-Specific Inherent Variability of Undrained Shear Strength Using Both Indirect and Direct Measurements
(American Society of Civil Engineers, 2018)Determining geotechnical design parameters (e.g., undrained shear strength Su) is an essential step in the analysis and design of geotechnical structures at a particular site. The estimated design parameters are ... -
Application of Linguistic Clustering to Define Sources of Risks in Technical Projects
(American Society of Civil Engineers, 2018)Risk identification is adversely affected by the still existing definitional and applicational discrepancy regarding risks and other related notions, such as hazards and impacts. A paradigm shift is beginning to be in ... -
Mental Models of Navigation Safety to Inform Risk Management Decisions: Case Study on the Houston Ship Channel
(American Society of Civil Engineers, 2018)The Houston Ship Channel (HSC) is one of the busiest waterway corridors in the United States. Since the channel’s expansion in 25, concerns have arisen about design deficiencies in the HSC in the area of the Bayport Ship ... -
