Abstracts

Ultra-HighPerformance Concrete (UHPC) is typically used as connection between precast bridge girders in Accelerated Bridge Construction (ABC). An alternativelow-cost mix design using polypropylene fiber-reinforced High-Early Strength (HES)concrete was proposed by the Idaho Transportation Department (ITD).In this thesis, finite elementmodelsusing Abaqusbending testsof beams representing a 1-foot strip of the bridge deck were developedfor a performance comparison between UHPC and HES. The “concrete damaged plasticity” material model was used for concrete and cohesive surface interaction represented the interface bond showed good results in representing the interface between the closure pourand precast concrete. The finite element models were able to produce results similarto the experimental results and also show that HES provides a comparable replacement for UHPC.
