Abstract
The steel structure will be subjected to alternating loads during its service, so the fatigue damage will gradually accumulate. Although fatigue damage may not cause immediate failure of the steel structure, the mechanical properties of the steel structure will inevitably be weakened. In this paper, the changes in mechanical properties of Q355B and Q690D steels after fatigue damage were investigated by static tensile tests. Then, a numerical simulation method for structural steel after fatigue damage was proposed. Finally, the results obtained from the finite element model were compared with the experimental results to verify the accuracy of the proposed numerical simulation method.
