Abstract: In this paper, an effective method to determine the skeleton curve parameters of corroded compression bending members is proposed to establish its restoring force model. In the process of parameter fitting, the hypothesis that the skeleton curve shape of damaged members is similar to that of undamaged members is introduced. At the same time, the two-dimensional plane section assumption is adopted to simplify the mathematical model and reduce the amount of calculation. Several groups of experimental data are compared with the prediction method proposed in this paper to verify its correctness. The case study shows that the experimental trend can be well captured.
