Investigation of Effects of Time Preference and Risk Perception on Life-Cycle Management of Civil Infrastructure
(ASCE, 2020)Civil infrastructure systems have two essential characteristics: long service life and low probability of failure. Under these circumstances, life-cycle management (LCM) of civil infrastructure involves time preference of ... -
Climate Change Considerations for Seismic Vulnerability Assessment of Aging Highway Bridges
(ASCE, 2020)Aging affected structural components negatively impact the lateral load–resisting capacity and fragility of highway bridges during seismic shaking. Until now, a majority of existing literature on corrosion deterioration ... -
Applying Derived Distribution Method to Microlevel Driving Behavior Characteristics to Quantify Uncertainties in Traffic Stream Flow and Density
(ASCE, 2020)The flows and densities of traffic streams play an important role in defining the performance of roadways and corresponding improvement strategies. Traffic flows and densities are the outcome of complex psychophysical ... -
Probabilistic Risk Management Framework for Tolerance-Related Issues in Modularized Projects: Local and Global Perspectives
(ASCE, 2020)Modular components and assemblies involve complex geometric relationships whereby excessive geometric variability in a critical component can affect the overall geometry of the aggregated and assembled structure onsite. ... -
Decentralized Decision Making for the Restoration of Interdependent Networks
(ASCE, 2020)This study introduces tractable algorithms to model the decentralized decision-making process for postdisaster restoration of interdependent networks. Restoration strategies are devised by a host of agents, who control ... -
Risk Evolution of On-Bridge Crowds through Region-Level Floor Field Model
(ASCE, 2020)Footbridges, as the fundamental structures spanning natural or artificial obstacles, not only perform the function of weight-bearing but also entail the role of pedestrian transporting. From the pedestrian transporting ... -
Routing in a Stochastic Network with Nonrecurrent Incidents: Behavioral Interpretation of Dynamic Traffic Assignment
(ASCE, 2020)In an advanced traveler information system (ATIS), this study examines how to map a driver’s time constraints and risk-taking behavior to real-time routing in a probabilistic time-dependent network (or stochastic network). ... -
Performance of US Concrete Highway Bridge Decks Characterized by Random Parameters Binary Logistic Regression
(ASCE, 2020)This study employs a random parameters binary logistic regression (LR) to characterize the impact of environmental and structural parameters on concrete highway bridge deck deterioration nationwide. Two specific gaps in ... -
Quantitative Risk Assessment of Road Tunnel Fire Safety: Improved Evacuation Simulation Model
(ASCE, 2020)With a view to enhance road network’s safety, it is crucial to focus primarily on its critical infrastructures, one part of which is tunnels. Fire safety of tunnels concerned intensely the public opinion after the disastrous ... -
Analytic Probabilistic Safety Analysis under Severe Uncertainty
(ASCE, 2020)Exact analytic expressions are given to evaluate the reliability of systems consisting of components, connected in parallel or series, subject to imprecise failure distributions. We also proposed a simplified version of ... -
Road Safety: Risk Management Perspective
(ASCE, 2020)Risk is ubiquitous and is associated with a very wide range of human activities. This has resulted in the development of an internationally agreed set of principles and guidelines for risk management in general. This paper ... -
Probability Propagation Method for Reliability Assessment of Acyclic Directed Networks
(American Society of Civil Engineers, 2019)Many civil infrastructure systems that deliver resources from source points to sinks, e.g., power distribution and gas pipeline networks, can be described as acyclic directed networks comprising nodes and links. ... -
Evaluation of Stress-Dependent Methods for the Punch-Through Capacity of Foundations in Clay with Sand
(American Society of Civil Engineers, 2019)This paper compiled 159 centrifuge tests for foundations in clay with interbedded sand where punch-through failure was observed. The accuracy of initial- and failure-stress-dependent methods was quantified by the mean and ... -
Analysis of Impartial Implementation in Practice of Risk Identification in Technical Projects
(American Society of Civil Engineers, 2019)Risk identification in the case of technical projects is an issue that has been extensively studied in many previous research efforts; however, a thorough study of the respective literature clearly reveals a methodological ... -
Flexible Booster Chlorination: Design and Operation for Water Distribution Systems under Uncertainty
(American Society of Civil Engineers, 2019)Uncertainty inherent in the operations of water distribution systems (WDSs) poses risks to public health due to the likely insufficient or excessive disinfectants caused by inevitable changes in WDS operations. A methodology ... -
Model Selection and Uncertainty Quantification of Seismic Fragility Functions
(American Society of Civil Engineers, 2019)A fragility function quantifies the probability that a structural system exposed to a given hazard exceeds an undesirable limit state event conditioned on the occurrence of a hazard level. Multiple sources of uncertainty ... -
Risk-Based Maintenance Planning for Rail Fastening Systems
(American Society of Civil Engineers, 2019)Failures in rail fasteners can lead to misalignments of the rails and even cause a train derailment. Current inspection and maintenance regimes for rail fasteners, however, do not adequately address the credible failure ... -
