| Abstract: | By creating a model based on BP neural network, data fitting of square concrete-filled steel tube concentrically loaded in compression was carried out in the article. The fitting result based on BP neural network was compared with the ten - order polynomial fitting result. The BP neural network model could accurately fit the data of square concrete-filled steel tube. The performance of BP neural network model in nonlinear fitting was excellent and the fitting precision was high. |
