The cracking damage of concrete bridge will seriously affect the overall safety of a structure. In this study, based on the numerical simulation, finite element analysis was carried out on the concrete T beam through the ANSYS software, and the selection of elements and the constitutive relationship of materials in the numerical simulation were introduced. It was found from the results of numerical simulation that the cracks of T beam continued to develop under the action of load, the concrete entered the plastic state from the elastic state and the mid-span deflection increased with the increase of load. In the case of the change of cracks, the larger the crack height, the larger the crack range of the beam. With the increase of load, the structural rigidity continued to degenerate, and the compressive stress of the concrete also increased. The research in this paper proves the validity of numerical simulation in the study of nonlinear mechanics of beam bridge and also makes some contributions to the study of crack damage of beam bridge.
