Analysis of Superstructures of Integral Abutment Bridges

The primary objective of this research is to better understand integral abutment bridge (IAB) structural performance from the perspective of superstructure behavior. The research approach consists of a combination of literature review, Department of Transportation (DOT) surveys, analytical modeling of IAB structural systems, and field monitoring of IABs, in hopes of ultimately providing improved design and construction details for IAB superstructures, consistent with actual stress distributions observed in the field. This could then lead to expanded use of IAB structures that are more optimized with respect to their superstructures, while still providing all the benefits of a joint-free bridge. Deeper understanding of IABs developed in this research may also be valuable in related investigations of seismic behavior, design, and performance of IAB structures.
