SuperLoad Crossing of Millard Avenue Bridges Over Duck Creek and CSX Railroad

A series of superloads crossed the Millard Avenue Bridges which span over Duck Creek and the CSX railroad. These bridges are located in Toledo and Oregon, Ohio, on the route from the Port of Toledo to a nearby oil refinery. The bridge over Duck Creek is a three span straight slab-on- steel girder bridge and the CSX is a horizontally curved slab-on- steel girder bridge having five continuous spans. The horizontal curve of the steel super structure is achieved by kinking the girder lines at the field splices.The tasks requested to be performed by the Cities of Toledo and Oregon were load tests and load ratings to verify that twelve super loads could safely traverse the bridges, determine if any measurable damage was caused by the heavy loads and establish load rating procedures for future superloads. The work presented in this thesis is the comparison of the analytical and field strain measurements for the largest and last superload to cross the bridge, the comparison of the field strain measurements for five diagnostic dump truck tests the development of a calibrated finite element model for the Duck Creek bridge. An examination of the lateral bending strain at the splices for the CSX bridge.The field and analytical strain fit well for the superload crossing. The diagnostic tests showed no observable change before and after the superload crossing.
