Experimental Assessment Of The Current Load Rating Procedures For A Corroded Steel Ridge Girder In Massachusetts, Brendan T. Knickle
Experimental Assessment Of The Current Load Rating Procedures For A Corroded Steel Ridge Girder In Massachusetts, Brendan T. Knickle
Structural Engineering Masters Projects
The work conducted for this project involves an experimental assessment of the Massachusetts Department of Transportation’s (MassDOT) existing procedure for determining the resistance of a corroded steel girder end when load rating a bridge. Three steel girders with significant corrosion developed over a 79-year service life were obtained from a recently rehabilitated bridge and loaded to determine the girders corroded resistance. A testing rig was designed in the UMass Amherst Brack Structural Testing Laboratory to both apply a shear dominated load to the corroded girder and withstand the developed lateral loads throughout the analysis. Reaction force data obtained from the …
