Fiber Reinforcement in Prestressed Concrete Beams
Prestressed concrete I-beams are used extensively as the primary superstructure elements in Texas highway bridges. A commonly observed problem in these beams is the appearance of end zone cracking due to the prestressing forces, thermal effects of hydration, shrinkage and temperature variation. Even though a large quantity of transverse steel reinforcement is provided in the end zone, the cracking problem persists. The research described in this report was targeted to develop a workable steel fiber reinforced concrete mix that would be capable of partially or completely replacing the dense traditional reinforcement and eliminating cracking in the end zones.
