Demonstration of Corrosion-Resistant Hybrid Composite Bridge Beams for Structural Applications
Abstract
The Army has 1,500 vehicular bridges on its installations that can incur high maintenance costs and even early replacement as a result of corrosion of the steel support structures or the reinforcing bar in the concrete. The application of corrosion-resistant technology can extend the service life of bridges and reduce maintenance costs. The Office of the Secretary of Defense Corrosion Prevention and Control Program project demonstrated and validated a corrosion-resistant hybrid-composite beam (HCB) for the reconstruction of a one span of a traditional steel and concrete bridge at Fort Knox, Kentucky. The HCBs were installed on half of the bridge, and conventional steel beams were installed on the other half. Structural analysis of the bridge was performed, and the span with HCBs was found to meet all design specifications and load ratings. This technology can increase the life cycle of bridge infrastructure when utilized in new construction and replacement by the Army and all other federal agencies. The technology's return on investment (ROI) is 4.22
