Abstract: In order to expand the use of FRP in new structures, a satisfactory degree of understanding is required for the behavior of members reinforced with FRP rebars. The aim of the current study is to investigate the concrete contribution to shear strength for beams reinforced with FRP longitudinal bars. A review for the available test results for members reinforced with FRP longitudinal bars without shear reinforcement results a database of specimens from different researchers. The available equations for predicting the value of the concrete shear strength for FRP reinforced members were also collected. An experimental test program was conducted to verify the results for beams with low longitudinal reinforcement ratios. A comparison was made between the experimental results and the shear strengths calculated using the different available equations. Based on the comparison and the experimental program results, the equation adopted by Building Research Institute (BRI)-Japan was found to fit best with the experimental results.
