Assessing The Capacity of Four Steel Hinges Extracted from Existing Bridges

Girder hinge connection details are susceptible to corrosion and stress concentrations that can lead to reduced capacities in steel bridges. The Minnesota Department of Transportation (MnDOT) has recently replaced and salvaged four girder hinges with the goal of testing to investigate their actual capacities and the accuracy of the results of the numerical models.
