Abstract
Based on bending fiber reinforced concrete beam, through the nonlinear analysis, the paper discuss the constitutive models of concrete and reinforcement, the properties of their element and the models of concrete beams reinforced with FRP bars. Using nonlinear analysis and comparing numerical results with experimental results, the fiber reinforced concrete beam bending terminal numerical model constructed in this paper can simulate the entire process of internal force and deformation of fiber reinforced concrete beams, and describe cracks in the formation and extension and the failure process and failure form, which also can provide enough precision to the practical engineering and scientific research. Meanwhile, the finite element computation model verified by test can provide more reactive information to effective structure computation model.
