RISNext Generation Fragility Functions for Seismically Designed Highway Bridges in Moderate Seismic Zones
Publisher: ASCE
Abstract: Despite the potential of high-consequence events, rarity of earthquake occurrences in moderate seismic zones and a misconstrued perception of risk has often led to a delayed onset of seismic detailing practices for highway ...
Climate Change Considerations for Seismic Vulnerability Assessment of Aging Highway Bridges
Publisher: ASCE
Abstract: 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 ...
Parameter-Specific Uncertainty Partitioning in Seismic Fragility Assessment of Highway Bridges Using Heteroskedastic Metamodels
Publisher: American Society of Civil Engineers
Abstract: AbstractAt present, substantial literature exists on vulnerability assessment of bridges involving
metamodels that capture homoskedastic uncertainty; however, there is negligible research
on heteroskedastic response ...
Impact of Design Code Evolution on Failure Mechanism and Seismic Fragility of Highway Bridge Piers
Publisher: ASCE
Abstract: Seismic design principles of highway bridges across the globe have undergone significant modifications over the last decades, from little consideration of seismic effects to adoption of modern ductile detailing principles. ...
Consideration of Climate Change Effects on the Seismic Life-Cycle Cost Analysis of Deteriorating Highway Bridges
Publisher: ASCE
Abstract: Recent findings reported in the contemporary literature have underlined the criticality of including climate change effects in models of deterioration of civil engineering structures. Highway bridges, when exposed to ...
Improved Component-Level Deterioration Modeling and Capacity Estimation for Seismic Fragility Assessment of Highway Bridges
Publisher: ASCE
Abstract: This paper presents a novel vector-based seismic vulnerability assessment methodology for deteriorating highway bridges by uniquely accounting for realistic deterioration of key structural components. The proposed framework ...
Incorporating Modeling Uncertainty in Seismic Life-Cycle Cost Analysis under Mainshock-Aftershock Sequences
Publisher: American Society of Civil Engineers
Abstract: AbstractAftershocks following major seismic events (or “mainshocks”) often pose additional
seismic damage risk to structures that are already damaged in mainshocks and increase
financial losses. Therefore, seismic life-cycle ...
Aging Considerations in the Development of Time-Dependent Seismic Fragility Curves
Publisher: American Society of Civil Engineers
Abstract: This paper presents the formulation of a time-dependent seismic fragility format for bridges, as well as new insights into the potential effects of aging and deterioration on seismic vulnerability traditionally neglected ...
Sensitivity of Value of Information to Model and Measurement Errors
Publisher: ASCE
Abstract: The value of information (VoI) framework, based on Bayesian preposterior analysis, can be used to estimate the most likely benefit associated with a particular structural health monitoring (SHM) strategy. The errors within ...
Influence of Traffic Loading on the Seismic Reliability Assessment of Highway Bridge Structures
Publisher: American Society of Civil Engineers
Abstract: Traditionally, the impacts of traffic and earthquake loading have been considered independently when assessing bridge reliability. This paper presents a framework for joint seismic and live-load fragility assessment of ...
