Structural behavior of integral abutment bridge approach slabs
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-09-01 without embargo terms

Field monitoring of integral abutment bridge approach slabs
Integral abutment bridges (IABs) eliminate the joints between the deck and abutments and hence have become more prevalent in the U.S. due to lower maintenance costs and longer service life. Cracking of approach slabs immediately adjacent to IABs, which requires maintenance, repair, and even …

Assessment of structural concrete approach slab cracking at integral abutment bridges
… between the bridge deck and approach slabs in an integral abutment bridge (IAB) decreases the potential for water and salt damage to the bridge superstructure and bearings. However, the lack of expansion joints in an IAB can lead to complex interactions between the superstructure and substructure, …

Seismic behavior and design of integral abutment bridges in southern Illinois
The increased use of integral abutment bridges (IABs) throughout the United States has led to numerous studies concerning their behavior when subjected to a variety of loads. The seismic behavior of IABs is of particular interest to regions such as southern Illinois, where proximity to the New …

Field monitoring and numerical analysis of two Illinois integral abutment bridges
As compared to conventional jointed bridges, integral abutment bridges (IABs) require lower construction and maintenance costs and have a longer service life, leading to their increased use by Departments of Transportation in the U.S. However, due to their unique design, their structural behavior …

Measurement and evaluation of the performance of an integral abutment bridge deck
… thesis is based upon the instrumentation of an integral abutment bridge, with a reinforced concrete deck on 3-span, continuous steel girders. The bridge is located in Evansville, West Virginia, at the intersection of WV Route 92 South and US Route 50 East. An instrumentation system was developed …

Illinois integral abutment bridges: behavior under extreme thermal loading and design recommendations
… (IDOT) has increasingly constructed integral abutment bridges (IABs) over the past few decades, similar to many other states. Throughout the United States, IABs are preferred over conventional bridge construction because they are generally cheaper and easier to construct; have lower …

IMPACT OF SOIL-STRUCTURE INTERACTION ON SEISMIC BEHAVIOUR OF INTEGRAL ABUTMENT BRIDGES
… the behaviour of infrastructure, such as integral bridges, during seismic loading will allow bridge and geotechnical engineers to design these bridges to operate safely during and after earthquake loading and, therefore, reduce the risk of loss of lives and infrastructure damage. …

On the Performance of Super-Long Integral Abutment Bridges: Parametric Analyses and Design Optimization
The concept of "integral abutment bridge" has recently become a topic of remarka-ble interest among bridge engineers, not only for newly built bridges but also during refurbishment processes. The system constituted by the substructure and the superstructure can achieve a composite action responding …

Thermal Response of Integral Abutment Bridges With Mse Walls: Numerical Analyses and a Practical Analysis Tool
The advantages of Integral Abutment Bridges (IABs) include reduced maintenance costs and increased useful life spans. However, comprehensive and practical analysis tools for design of IABs have not been developed to account for the impacts of thermal displacements on abutment and foundation …

Evaluation of the need for longitudinal median joints in bridge decks on dual structures
… to accelerated deterioration. At the same time, integral abutment bridges are in wide use (in Iowa and beyond), since they have no expansion joints to allow leaking of chloride-contaminated water that can corrode the bottom of the deck and the adjacent girders. Thus, the practice of limiting …

Experimental and Analytical Investigations of Piles and Abutments of Integral Bridges
Bridges without expansion joints are called "integral bridges." Eliminating joints from bridges crates concerns for the piles and the abutments of integral bridges because the abutments and the piles are subjected to temperature-induced cyclic lateral loads. As temperatures change daily and …
