If the steel is replaced with FRP, with a modulus of elasticity of 6,000 ksi, the strain in the FRP would be 0.002 at this same stress. Even using a #3 FRP bar in place of the steel would only increase the stress to 20,400 psi and the strain to 0.0034. This small strain will result in less than the AASHTO guideline of 0.04 inches of crack width.
