Bearing Capacity Analysis of CFRP Strengthened Steel Plate with Hole under Axial Tension under Load

In view of the CFRP reinforcement with a central holed plate under load, the ABAQUS software is used to simulate the axial tension of the component, which provides the theoretical basis for the application of CFRP reinforcement with the central holed bearing steel plate under the load, and establishes the numerical model of the CFRP reinforcement with the center holed plate under the load. Under the condition of equal stiffness, the influence of the different load percentage of CFRP on the bearing capacity of the holed steel plate under non load and the bearing capacity of the holed plate under the load is analyzed.The simulation results show that, for the condition that the holed steel plate reinforced with CFRP is not considered under the load, the yield load and the ultimate load of the holed steel members reinforced by the CFRP reinforcement can be obviously improved. And then the finite element simulation of the holed steel plate with CFRP reinforcement under the load is carried out. We can conclude that the ultimate load of reinforced components decreases with increasing loading level.
