Abstract:Oregon has several hundred reinforced concrete deck girder (RCDG) bridges built in the late 40s to the early 60s that now exhibit diagonal cracks. The Oregon Department of Transportation contracted with Oregon State University to evaluate methods to accurately estimate the load capacity of cracked girders and to develop a procedure to load rate the girders. The investigation encompassed field testing, laboratory testing, and analysis that provided a reliability-based load rating methodology.
