Develop Concrete Girder Splice Details with Application of Ultra-High-Performance Fiber-Reinforced Concrete (UHP-FRC)
The project aims to leverage Ultra-High-Performance Fiber-Reinforced Concrete (UHP-FRC) to enhance the flexural and shear strengths, cracking resistance, durability, and bond between concrete and reinforcing bars in girder splices for Texas Department of Transportation's (TxDOT's) precast girder bridges. This project will develop efficient UHP-FRC splice details to connect simply supported precast girders at pier locations, using the Simple for Dead and Continuous for Live Load (SDCL) approach for the splice design. The UHP-FRC girder splice can eliminate bridge expansion joints, reducing maintenance costs and enhancing durability. Objectives include conducting a literature review, developing UHP-FRC mix designs and construction methods, determining splice and girder end reinforcing details, and evaluating connection performance under live load conditions. The project will provide comprehensive UHP-FRC splice construction guidelines for TxDOT's girder and composite deck bridges, aiming to improve structural integrity, durability, and maintenance efficiency.
