Lap-Spliced Rebar Connections with UHPC Closures
(American Society of Civil Engineers, 2018)Ultrahigh performance concrete (UHPC) is gaining attention from the bridge community as a compelling option for closure pours that complete prefabricated bridge element (PBE) connections; these connections typically use ... -
Untitled
(American Society of Civil Engineers, 2018)This article presents dynamic tests of three damage-resistant segmental hollow-core bridge columns with posttensioned unbonded strands. One column was constructed without energy dissipaters, whereas the other two columns ... -
Automated Acoustic Scanning System for Delamination Detection in Concrete Bridge Decks
(American Society of Civil Engineers, 2018)In this study, an automated acoustic scanning system was developed for rapid delamination detection on concrete bridge decks. A new ball-chain impact source was designed by combining the advantages of chain-drag (rapid ... -
Live Load Distribution and Dynamic Amplification on a Curved Prestressed Concrete Transit Rail Bridge
(American Society of Civil Engineers, 2018)A recently constructed and commissioned in-service light rail transit bridge in Denver, Colorado was examined analytically and via field testing to study its live load performance. The bridge is a four-span horizontally ... -
Modeling Corrosion in Suspension Bridge Main Cables. II: Long-Term Corrosion and Remaining Strength
(American Society of Civil Engineers, 2018)Reliably assessing the condition and safety of suspension bridges poses the problem of determining the remaining strength of bridge cables in their present state. Corrosion of the steel wires, which together comprise the ... -
Modeling Corrosion in Suspension Bridge Main Cables. I: Annual Corrosion Rate
(American Society of Civil Engineers, 2018)Accurately determining the current state of the main cables of a suspension bridge is critical to assessing the safety of the bridge. These cables are composed of thousands of individual bridge wires, each of which ... -
Integrated Superstructure-Substructure Load Rating for Bridges with Foundation Movements
(American Society of Civil Engineers, 2018)Superstructures of highway bridges are load rated regularly as a part of the National Bridge Inspection Standards (NBIS). It is well known that the load-carrying capacity of a superstructure is affected by foundation ... -
Untitled
(American Society of Civil Engineers, 2018)Restrain devices, being of low cost and easy to install, are often used to limit the relative displacements between the decks and columns in a simply supported bridge. Although the current guidelines have provided different ... -
Primary Bond Mechanism Behavior of Posttensioned 7-Wire Strand during Load Exposition
(American Society of Civil Engineers, 2018)The three primary bond mechanisms of a 7-wire strand are adhesion, friction, and mechanical interlocking between the concrete surface and the strands’ helical surfaces. Once adhesion fails as a result of micromovements of ... -
Time-Dependent Effect of Corrosion on the Mechanical Characteristics of Stay Cable
(American Society of Civil Engineers, 2018)Cable-stayed bridges, of which there are up to 5 around the world, are often the first choice for long-span bridges. As stay cables increase in service life, rust becomes the most common challenge. At present, more than 2 ... -
Tsunami-Like Wave Loading of Individual Bridge Components
(American Society of Civil Engineers, 2018)Research concerning tsunami forces on bridges has focused primarily on determining total forces either experimentally or numerically, often with the goal of establishing total force demand equations. However, this approach ... -
Full-Response Prediction of Coupled Long-Span Bridges and Traffic Systems under Spatially Varying Seismic Excitations
(American Society of Civil Engineers, 2018)A long-span bridge supports a large number of vehicles, which are usually present when an earthquake strikes the bridge site due to the low predictability of earthquake events. Existing seismic analyses of long-span bridges ... -
Regression-Based Adjustment Factor to Better Estimate Shear Capacity for Load-Rating Simple Span PC Girders
(American Society of Civil Engineers, 2018)In this study, an adjustment factor was developed to better estimate the shear capacity of simple span prestressed concrete (PC) girders, for intended use in load rating. The adjustment factor is expressed as a function ... -
Mechanistic Deterioration Modeling for Bridge Design and Management
(American Society of Civil Engineers, 2018)The combination of continued highway bridge aging and constrained maintenance, repair, and replacement budgets create the pressing need to develop strategies to allocate available management resources most effectively. ... -
Safety Assessment of Continuous Beam Bridges under Overloaded Customized Transport Vehicle Load
(American Society of Civil Engineers, 2018)This paper presents the safety assessment of prestressed concrete box-beam (PCB) bridges under customized transport vehicle (CTV) load. First, the recorded data of 81,616 CTVs were used in the investigation of load ... -
Validation of OpenSees for Tsunami Loading on Bridge Superstructures
(American Society of Civil Engineers, 2018)The performance of bridges prone to tsunami hazards is critical to the resilience of coastal communities. An important component of resilience is the development of design guidelines, which requires simulating the hydrodynamic ... -
Seismic Vulnerability Assessment and Retrofitting Design of a Multispan Highway Bridge: Case Study
(American Society of Civil Engineers, 2018)Seismic vulnerability is a critical issue in Italy, because the bulk of existing structures were designed before enforcement of the new national building code in 28 and the ensuing seismic risk map, which assigns a ... -
Shape Optimization of UHPC Shear Keys for Precast, Prestressed, Adjacent Box-Girder Bridges
(American Society of Civil Engineers, 2018)Adjacent box-girder bridges are a popular choice for short- to intermediate-span bridges in several states because they are easy, quick to build, and cost-effective. Although longitudinal shear keys filled with grout between ... -
Empirical Validation of Bayesian Dynamic Linear Models in the Context of Structural Health Monitoring
