LABORATORY AND FIELD TESTING OF COMPOSITE BRIDGE SUPERSTRUCTURE

Bridge rehabilitation utilizing a hybrid fiber-reinforced polymeric composite has recently been completed in southwestern Virginia. This project involved replacing the superstructure in the Tom's Creek Bridge, a rural short-span traffic bridge with a timber deck and corroded steel girders, with a glue-laminated timber deck on composite girders. To verify the bridge design and to address construction issues prior to the rehabilitation, a full-scale mock-up of the bridge was built and tested in the laboratory. This set-up utilized the actual composite beams, glue-laminated timber deck panels, and the skewed geometry implemented in the rehabilitation. The bridge was field-tested under controlled conditions. Both tests examined service load deflections, girder strains, load distribution, degree of composite action, interpanel deck deflections, and impact factor. Field test results indicate a service load deflection of L/400 under moving loads and a high factor of safety in the composite members against material failure. Data from the field test serve as a baseline reference for future field durability assessments as part of a long-term performance and durability study.
