As part of the FHWA (Federal Highway Administration) High Performance Concrete Bridge Program, two full-scale truckload tests of Bridge GUE-22-6.57 were carried out. The main objectives of these tests were to investigate the static and dynamic response of the high performance concrete (HPC) structure. A secondary objective was to investigate the load transfer between the box girders through experimental middepth shear keys. The structure was loaded using standard Ohio Department of Transportation (ODOT) dump trucks. A model test of the bridge was conducted as well. It was found that the bridge behavior is well predicted using simple models. The bridge behaves as a single unit and all girders share the load almost equally. The dynamic behavior of the bridge is typical for comparable structures.
