Prediction of ultimate bearing capacity of fly ash concrete-filled square steel tube based on BP neural network

By creating a model based on BP neural network,prediction of ultimate bearing capacity of fly ash concrete-filled square steel tube concentrically loaded in compression was carried out.The predictive values dovetailed nicely with the experimental values.The BP neural network model could accurately forecast ultimate bearing capacity of fly ash concrete-filled square steel tube.The BP neural network model was of high precision and provided a new way to get ultimate bearing capacity of fly ash concrete-filled square steel tube.
