The Use of Autoregression to Generate Patterns of Extreme Loading on Long-Span Bridges
(2023)For long-span bridges, there is little known about the gaps between vehicles in the congested traffic loading events that govern the characteristic maximum load effects. In many studies for the derivation of national ... -
Optimizing the Bridge Maintenance Schedule of Transportation Networks under Uncertainty: A Simheuristic Approach Considering Reliability
(2023)In this work, we consider optimal maintenance scheduling policies of bridges in transportation networks. The network is composed of a set of urban centers, connecting roads, and corresponding bridges. Bridges, as one of ... -
Sensitivity analysis of adjusted partial factors for the assessment of an existing reinforced concrete bridge
(2023)Design standards for Reinforced Concrete (RC) bridges are generally based on a semi-probabilistic format using partial factors to take into account material, geometrical and load effect uncertainties. In the case of an ... -
Predicting the long-term creep behaviour of glued laminated elements
(2023)The long-term creep behaviour of timber structures is an ever-increasing research focus given the rise of mass timber buildings across the world. Experimentally examining such properties is a time-consuming and costly ... -
Probabilistic evaluation of road bridges under heavy load platforms
(2023)Road bridges are one of the most important infrastructure assets for global transportation. With the growing freight demands, traffic loads on bridges are also increasing. Specifically, the increase of heavy load platforms ... -
Network Reliability Analysis and Complexity Quantification Using Bayesian Network and Dual Representation
(2023)Modern society operates upon various lifeline networks such as transportation networks, power networks, and gas distribution networks. To secure their reliable operations, it is critical to evaluate their reliability. ... -
A Method for Probabilistic Analysis in Structural Dynamics Based on Separation of Aleatory and Epistemic Uncertainties
(2023)There is still much philosophical debate about whether a frequentist or subjective view of probability should be adopted. Some uncertainties (typically aleatory uncertainties) are naturally modelled using a frequentist ... -
Application of Statistical Method on Field Pile Loading Test Result Analysis
(2023)Most geotechnical engineering issues face great degree of uncertainties since it studies a natural material - soils and rocks. So the analysis of data obtained from field tests requires intensive data processing in order ... -
A Generalized Framework for Reliability Assessment of Bridges using Adjusted Partial Safety and Combination Factors
(2023)Assessment of degrading infrastructure, particularly bridges, represents a growing challenge for structural engineers. While traditional strategies for bridge assessment, such as a code-based rating factor assessment, are ... -
A value of information framework for quantifying the value of reliability assessment for a steel railway truss bridge
(2023)Infrastructure is frequently subject to various loading and environmental stressors that cause degradation of its performance with time. Management of such degrading infrastructure is conditioned upon its estimated ... -
A response spectra based intensity measure for seismic system reliability
(2023)This work studies a newly proposed seismic intensity measure (IM) and evaluates its efficiency and sufficiency with respect to ground motion records and structural response, with the end goal of computing structural system ... -
Probabilistic risk assessment of coastal infrastructure systems under climate change
(2023)The vulnerability of coastal infrastructure systems can be affected by various climate-related hazards, such as tropical cyclones. Over the long term, the impact of hazards on systems may be magnified due to exposure to ... -
Ground motion model for median directional inelastic spectral displacements
(2023)Peak inelastic displacement of single-degree-of-freedom (SDOF) systems has been shown to be an efficient ground motion (GM) intensity measure (IM) for estimating the structural demand. Most ground motion models (GMMs) are ... -
A Modern Bayesian Approach to Model Updating of Bridges Considering Measurement Uncertainty
(2023)Existing bridges were designed using contemporaneous standards, but increased loading due to increased freight demand must be considered in their ongoing safety management. Finite-Element (FE) modelling provides the ... -
Combining Seismic Risk Analysis and Network Modeling to Assess Hospital Service Accessibility in the Bay Area, California
(2023)Earthquakes can damage hospitalsﾒ infrastructure and disrupt critical healthcare functions. For example, the Northridge Earthquake in California damaged 11 acute hospitals, and eight had to be evacuated. These disruptions ... -
Probabilistic Modeling of Hurricane-Induced Debris Impacts for Coastal Community Resilience Analysis
(2023)Climate disasters such as hurricanes significantly impact coastal communities, posing critical challenges to their resilience. Besides direct economic and social losses, coastal communities suffer from indirect cascading ... -
Bridge Network Decisions with Mobile Technology Integration
(2023)The interconnectedness between structural failure probabilities and systemic features is crucial in civil infrastructure safety and integrity assessment in post-disaster applications. The combination of systemic reliability ... -
Machine learning for prediction of undrained shear strength from cone penetration test data
(2023)Being widely employed in the design phase of many large-scale infrastructure projects, the shear strength of soil has always been one of the most important parameters in geotechnical engineering. Many methods have been ... -
An Earthquake Early Warning Decision Support System for Railway Bridge Infrastructure
(2023)Earthquake early warning (EEW) systems deliver actionable information seconds before the arrival of damaging seismic waves from an oncoming earthquake at a target site. Such information can potentially contribute to ... -
Shock Degradation Process to Assess the Reliability of Bridges Subjected to Scouring and Climate Change
(2023)Climate change impacts the infrastructure in several ways. In the particular case of bridges crossing rivers, climate change may have a direct impact on the river discharge and, consequently, may modify the bridge scouring ...
