摘要：Based on the concrete constitutive relations provided by the concrete structure design specifications, a three-point bending beam numerical analysis was performed by introducing a damage plastic damage model and using ABAQUS to add a concrete parameter plug-in. The three-point bending test of the beam was carried out by the fatigue test machine, and the results of theoretical calculation and numerical simulation were compared to verify the correctness and reliability of the plastic model of concrete damage (CDP model). At the same time, the shortcomings of the theoretical calculation were pointed out, which can be used as a reference for the later engineering calculation and the research of concrete.
