Abstract

In this paper, the size effect of shear capacity of concrete beams reinforced with FRP rods without stirrups is analyzed using the developed fictitious crack model based on fracture mechanics. The numerical analysis is performed for the case of different reinforcement stiffnessEs, 2.0×106, 1.0×106 and 6.7×105 kgf/cm2, and for different beam depth 10, 20, 50,100,200 and 300 cm.The result shows that the shear capacity declines with a decrease of reinforcement stiffness and the tendency of size effect of a beam reinforced with FRP is similar to that reinforced with normal steel bers
