A combined experimental and theoretical investigation on the structural behavior of fiber reinforced plastic (FRP) bars is presented. Test results indicate that the ultimate strength decreases with increase in the rod diameter. A new model is formulated that relates the strength of the specimens with their diameter. Predictions from the model show excellent correlation with the tension test results. FE analysis is employed to justify the assumptions made in the model.
