• abstract = "black boxes, the GP-SR method delivers transparent, interpretable equations, making it highly accessible for researchers and practitioners alike. In particular, the GP-SR framework is optimised in this study by a simulated annealing (SA) algorithm, which enhances the framework's ability to escape local optima and greatly accelerates the search for optimal symbolic regression models. To ground our model, a comprehensive experimental database, comprising 130 corroded RC columns with flexural failure under cyclic loading, is compiled in this study. This dataset underpins feature selection, model training, and validation. The results demonstrate that the SA-optimised GP-SR method not only outperforms conventional approaches in predicting the post-corrosion strength of RC columns but also does so with high precision for lateral deformation predictions across a spectrum of levels of corrosion. Moreover, despite the constraints posed by the limited collected data, the SA-optimised GP-SR model demonstrates potential in extending its predictive scope to columns exhibiting flexural-shear failure. This broader generalizability enhances the model's usefulness, offering up an expedient approach for modelling and evaluating the residual seismic capacity of corroded RC columns",
