Abstract
This paper contributes to the scarce research available regarding the shear behavior of carbon fiber–reinforced polymer (CFRP) prestressed concrete beams. The beams were subjected to four-point bending and tested with different shear span to depth () ratios of 1.5, 2.5, and 3.5, with and without transverse reinforcement. For each group of four beams, two were reinforced with minimum required glass fiber–reinforced polymer (GFRP) stirrups according to the Canadian highway bridge design code. The results showed that the flexural rigidity and the shear capacity of the beams increase significantly as the ratio is reduced to 1.5 from 2.5. The data also showed that the minimum required GFRP stirrups are ineffective in beams with that are governed by arch action. The experimental results are compared to theoretical estimates from the shear formulas available in design codes and literature.
