Abstract:
A total of 66 beams, each 4.5 in. x 6 in. x 8 ft, were fabricated for a long-term bond and durability study currently in progress at the University of South Florida, Tampa. Thirty-three of the beams were pretensioned by two aramid fiber reinforced plastic rods and 33 by carbon fiber reinforced plastic rods. The beams were fabricated in two adjacent 400-ft prestressing beds normally used for producing 10-in. square steel pretensioned piles. The fabrication was successful and indicated that existing prestressing facilities can be readily adapted for FRP materials.
