ABSTRACT
Traffic disruptions due to construction projects place significant logistical and financial strains on the traveling public. Deterioration of steel bridge beam ends is a common issue. A more cost-effective, structurally efficient method to the conventional repair was developed using ultra-high performance concrete (UHPC) and shear connectors to encase the corroded beam end. The latest phase of this research project investigated improving simplicity and speed of construction of the UHPC repair. The method was implemented on an experimental full-scale plate girder, which had experienced severe corrosion damage and failed due to local buckling. All work was completed within an eight-hour shift including installation of the shear connectors, construction of the formwork, and casting of the UHPC. The results indicated that this repair method is a viable option to rapidly repair deteriorated beam ends while reducing project costs and limiting traffic disruptions.
