Behavior of Integral Abutment Bridges: Field Data and Computer Modeling

Integral abutment bridges have been constructed by State Departments of Transportation for a number of years. These bridges have been found to be cost effective from both an initial cost and life cycle analysis due to lower maintenance. However, there has been very little verification of the behavior of such structures. In general, the limits of design have been incrementally increased and accepted if the bridge behavior is deemed adequate. Unfortunately, this means that a true understanding of structure behavior is lacking. This has made it very difficult to develop design provisions for Integral Abutment Bridges. Those that exist are often based on very conservative assumptions pending research into the actual behavior of such systems. Verification of these design models is needed. This project will evaluate data from an existing instrumented Integral Abutment Bridge in Orange/Wendell, MA. The measured behavior will be compared to predicted behavior using Finite Element Modeling (FEM) and the existing Massachusetts Highway Department (MassHighway) design provisions.
