In this study, tension stiffening effect on load-deflection behavior of concrete beams reinforced with FRP
and steel bars is investigated. A total of 12 FRP reinforced concrete beam specimens, available in the
literature, were considered in the analysis. In order to investigate tension stiffening effect on flexural
behavior, bilinear tensile stress-strain model was considered for concrete material. In this model the
parameter αts controls the tension stiffening effect on the load-deflection behavior of the beam. Load-
deflection curves for the specimens were obtained with varying αts between 2 to 25, and then were
compared with the experimental results. In conclusion it is observed that the value of αts to be taken into
account for calculations in order to predict load-deflection behavior of reinforced concrete beams
significantly depend on the reinforcement ratio and the mechanical properties of reinforcement.
