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 …

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 …

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 …

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. …

Assessment of structural concrete approach slab cracking at integral abutment bridges
The elimination of expansion joints 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 …

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 …

Evaluation of the need for longitudinal median joints in bridge decks on dual structures
<p>ABSTRACT</p> <p>In the State of Iowa, bridge widths are typically limited to 60-ft. Although the justification for 60-ft is somewhat unknown, there is a desire, in some cases, to build wider bridges. For example, when dual bridges are constructed in urban areas they are frequently constructed …

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 …

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 …
