Abstract:

This report contains the contents of the project to enhance load rating methods for assessing corroded unstiffened steel beam ends for the six New England States. The first task of the project was to collect and compile inspection reports information provided by DOTs within New England. The research team was able to carefully identify trends and patterns in the data, which was used to determine the most common scenarios of corrosion encountered in bridges within New England States. Following this task, corroded bridge girder specimens were selected from existing structures to be documented and experimentally tested in the structural testing facility at UMass Amherst. The specimens were also computationally analyzed for their section loss and remaining capacity. The final goal of this project was to evaluate the load rating procedures across all of the New England States and recommend updates to the procedures based on our experimental and analytical results.
