Improved Load Rating Procedures for Deteriorated Steel Beam Ends with Deteriorated Stiffeners

This study aims to provide evaluation policies for the bearing capacity assessment of plate girders with corroded ends. The developed methodology was organized in three phases that each employed real corrosion data. First, inspection reports of bridges with corrosion-induced damage were processed to quantify the shape and bounds of the most common corrosion patterns. Second, full-scale laboratory tests were performed on two specimens built on naturally corroded girders obtained from decommissioned bridges in the Commonwealth of Massachusetts. Third, experimentally acquired data were employed to validate a composite girder level finite element model able to capture the failure load and mode of plate girders with corroded ends. Subsequently, by combining the previously defined corrosion patterns with computational modelling, an extensive parametric analysis was conducted to define the parameters that have influencing impact on the residual bearing capacity. Finally, analytical prediction tools were developed based on a data set of approximately 1,000 scenarios.
