End-Region Behavior and Shear Strength of Pretensioned Concrete Girders Employing 0.7-in. Diameter Strands
The Center for Transportation Research at the University of Texas at Austin has released a report that documents a research project about end-region serviceability and shear strength of Texas pretensioned bulb-tee girders (Tx-girders) that employ 0.7-in. diameter strands. The use of these larger diameter strands may improve the efficiency of pretensioned concrete elements by reducing the number of required strands and concentrating a greater steel area near the bottom of the cross section.
