The present research includes an experimental and theoretical approach to predict the moment-curvature relationship for the hybrid reinforced concrete (HRC) beams. First Secondly, the flexural rigidity of the HRC beams was calculated based on well-known empirical equations which applied to calculate the all From the comparison, it can be concluded that, the fiber analysis model has a good agreement with the experimental results from the beginning of loading up to the failure. The empirical equations which calculate the flexural rigidity of the beams are overestimate to predict the flexural rigidity of the HRC beams.
