N2 - This paper reports an alternative model for flexural crack control of FRP-reinforced members in which, consistently with current ACI 318 recommendations for steel-reinforced members, cracks are controlled indirectly through a maximum bar spacing requirement instead of being calculated directly. The proposed procedure results from the impracticalities associated with direct crack width measurement in concrete structures due to the high variability of both concrete cracking and crack width measurements. The proposed model explicitly accounts for the dominant effects that bar cover, FRP reinforcement stress, stiffness and bond properties have on cracking of FRP-reinforced concrete beams and one-way slabs. The procedure is seen as a simplification of the existing ACI 440.1R-06 direct crack control recommendations for serviceability design of FRP-reinforced members, rather than a modification.
