Full-Scale Testing Of 40 Year Old Prestressed Aashto Girders That Have Been Retrofitted In Shear By Externally Applied Carbon Fiber Reinforced Polymer Wraps, David A. Petty
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Utah Department of Transportation (UDOT) is interested in the application of rehabilitation techniques to strengthen their AASTHO prestressed bridge girders for shear. Utah's bridges are exposed to deterioration from rain, snow, and the introduction of salt for ice removable. This requires innovative rehabilitation techniques to address the deteriorations of their highway bridges, especially the ends of bridge girders where water and salt are more common due to construction joints. Carbon Fiber Reinforced Polymers (CFRP) are becoming more prevalent as a tool in highway bridge rehabilitation.
This research investigates the application of various CFRP systems that can be used as …
