Atmospheric Corrosivity Map for Management of Steel Infrastructure in India Using ISO Dose–Response Function and Gridded Data
(ASCE, 3/1/2021)The first-year corrosion rate (K) values of metals measured using standard protocols are indicative of the relative vulnerability of metal infrastructure to atmospheric corrosion at a given location. The Dose–Response ... -
A Hierarchical Bayesian Network Model for Flood Resilience Quantification of Housing Infrastructure Systems
(ASCE, 3/1/2021)Resilience is defined as the capacity of a system to withstand a natural hazard and to regain desirable performance after the occurrence of such disasters. Natural hazards, such as floods, earthquakes, hurricanes, and ... -
Revised Comparison of Tunnel Collapse Frequencies and Tunnel Failure Probabilities
(ASCE, 6/1/2021)Comparison of calculated failure probabilities of technical systems with observed failure frequencies is an important part of the assessment of probabilistic calculations and can point to significant factors that are ... -
Risk-Based Fatigue Design Considering Inspections and Maintenance
(ASCE, 3/1/2021)The different phases of a structure’s life-cycle are managed by different teams with little interaction. Correspondingly, the optimization of the individual phases is isolated and does not necessarily result in optimal ... -
Local System Modeling Method for Resilience Assessment of Overhead Power Distribution System under Strong Winds
(ASCE, 3/1/2021)During extreme weather events, such as hurricanes or major winter snowstorms, power distribution systems, such as the overhead power distribution systems consisting of wood poles and power wires, would encounter failures ... -
Optimizing Maintenance Decision in Rails: A Markov Decision Process Approach
(ASCE, 3/1/2021)The present paper contributes on how to model maintenance decision support for the rail components, namely on grinding and renewal decisions, by developing a framework that provides an optimal decision map. A Markov decision ... -
Failure Sampling with Optimized Ensemble Approach for Structural Reliability Analysis of Complex Problems
(ASCE, 3/1/2021)Failure sampling is a structural reliability method based on modified conditional expectation suitable for complex problems for which reliability index–based approaches are inapplicable and simulation is needed. Such ... -
Stochastic Analysis of Network-Level Bridge Maintenance Needs Using Latin Hypercube Sampling
(ASCE, 3/1/2021)The deterioration of bridge infrastructure along with diminishing funding resources necessitates reliable planning for future budget needs to maintain bridges at an acceptable level of performance. Although existing ... -
Effect of Soil Spatial Variability on the Structural Reliability of a Statically Indeterminate Frame
(ASCE, 3/1/2021)This paper presents a probabilistic procedure for assessing the structural responses of a statically indeterminate frame caused by soil spatial variability. Neglecting the soil spatial variability can underestimate the ... -
Global Decoupling for Structural Reliability-Based Optimal Design Using Improved Differential Evolution and Chaos Control
(ASCE, 3/1/2021)This paper presents a new method for performing reliability-based design optimization (RBDO) of structures based on sequential optimization and reliability assessment (SORA). SORA is an effective method for solving RBDO ... -
Temporal Disaggregation of Performance Measures to Manage Uncertainty in Transportation Logistics and Scheduling
(ASCE, 3/1/2021)Transportation planning for highways is informed by performance metrics with aggregated data that can obfuscate the uncertainty of performance conditions across hours, days, and weeks. Recent advances in data collection ... -
Risk-Based Priority Setting for Large-Scale Access Management Programs with Uncertain Mobility Benefits and Costs
(ASCE, 3/1/2021)Access management is a set of strategies used by transportation planners to address mobility concerns without the need for major highway expansions. Although access management can significantly improve highway mobility, ... -
Stochastic Process-Based Structural Reliability Considering Correlation between Upcrossings
(ASCE, 12/1/2020 )Structural reliability is a widely used tool to estimate the safety level and remaining service life of civil structures and infrastructure systems. Using a stochastic process to model the resistance or structural response, ... -
Metamodel-Based Prediction of Structural Damages due to Tunneling-Induced Settlements
(ASCE, 12/1/2020 )Tunneling-induced settlements in soft soil are inevitable and often suspected to impair buildings along the alignment. Public focus is thus targeted toward the consequences rather than the benefits of tunneling projects. ... -
Multiple-Surrogate Models for Probabilistic Performance Assessment of Wind-Excited Tall Buildings under Uncertainties
(ASCE, 12/1/2020 )Performance-based design (PBD) is becoming a benchmark approach for design and performance assessment of civil structures because it facilitates communication between stakeholders and design professionals with decision ... -
Improved Model for Computing Time-Variant Reliability Based on Outcrossing Rate
(ASCE, 12/1/2020 )Time-variant reliability problems have been studied widely by scholars recently, and they usually are solved on the basis of the outcrossing rate. The common method to calculate the outcrossing rate involves a static ... -
