The use of FRP reinforcement has no longer been a new issue. However, some issues in using FRP exist, such as brittleness, low elastic modulus, and inability to resist fire. One alternative to anticipate the FRP bars’ weaknesses is using a hybrid reinforcement combination of steel and FRP. Therefore, some researchers are increasingly investigating the application of hybrid reinforcement. Several researchers demonstrated that steel bars combined with Glass Fiber Reinforced Polymer (GFRP) bars increased reinforced concrete beams’ flexural capacity and ductility. Several studies have shown that the ductility of beams with hybrid reinforcement increases significantly but decreases with increasing hybrid reinforcement ratio. An accurate ductility analysis of reinforced concrete cross-sections with hybrid reinforcement is required to support the application of hybrid reinforcement. This paper presents a parametric study using the fiber element model to predict the flexural behavior of reinforced concrete cross-sections with hybrid reinforcement. The flexural behavior and ductility of the cross-sections are affected by the effect of ratio and the position of hybrid reinforcement. Recommended neutral axis depth for reinforced concrete cross-sections with hybrid reinforcement is also presented.
