Abstract

The width of flexural cracks in a concrete member internally reinforced with fiber reinforced polymer (FRP) bars depends on the characteristic of interfacial bond between the reinforcement and concrete. This paper reports the findings of a task group formed under the aegis of ACI Sub-committee 440 H (Reinforced Concrete) to evaluate and compare the effects of bond characteristics in previous and proposed equations for predicting crack widths. Based on the experimental data assembled by the task group, it is shown that the bond coefficient in the proposed equation by Frosch is 19% greater than the bond coefficient in the previous equation attributed to Gergely and Lutz.
