| Abstract: |
| Firstly, the plastic accumulation characteristics of materials under cyclic loading were elucidatedand the commonly used material constitutive relations in simulation analysis were highlighted. Next, the research on the ultimate load-bearing characteristics of complete structures was presented from both simulation and experimental perspectives under cyclic loading. Then, the impact of crack damage on structural load-bearing characteristics under cyclic loading was analyzed and the variation patterns of cracks under such conditions were elucidated. Finally, the methods for evaluating the residual strength of damaged structures under cyclic loading and the existing issues were summarized and discussed, providing a reference for researchers. |
