A bridge located at Old Westfield road in Granville, Massachusetts. This bridge is suffering from a considerable amount of corrosion, which is affecting Beam 1 (Girder 1) primarily, as seen in Images to the right.
The bridge consists of 8 girders, where the first 6 girders were built in 1939 and the last 2 girders were added later on in the 1950s as an expansion for another lane.
The project is analyzing the current condition for the deteriorated girder and how it is affecting the entire bridge, then providing new design solutions based on AASHTO standards and Massachusetts Department of Transportation (Mass DOT) manual for bridge designing.

Part of the analysis was designing an Ansys model to show and illustrate the difference in deformation and Von-Mises results, before and after the deterioration affected the targeted girder.
The model designed based on the hand calculation results that gives an idea about how much load applies on the targeted girder, as seen in images to the right.
The analysis proved the girder is failing, and it has to be fixed or replaced depends on the (Mass DOT) desire.
