The experimental program included five large-scale T-beams and four rectangular beams. The T-beams were prestressed with four 5/16-in diameter CFRP strands, while the rectangular beams were prestressed with only one CFRP strand. The prestressing levels were 50, 60 and 70% of the guaranteed capacity of CFRP strand.
