The experimental data is used to train and test the neural network. A comparative study was also carried out between the neural network model and the other existing models. It was found that the fundamental behavior of confined concrete columns can logically be captured by the neural network model. Besides, the neural network approach provided better results than the analytical and experimental models. The neural network-based model with R2 equal to 0.993 and 0.991 for training and testing the compressive strength, respectively, shows that the presented model is a practical method to predict the confinement behavior of concrete columns wrapped with FRP since it provides instantaneous result once it is appropriately trained and tested.}, keywords = {Concrete columns,CFRP,Confinement,Artificial Neural Networks,Models}, url = {https://www.jsoftcivil.com/article_115527.html}, eprint = {https://www.jsoftcivil.com/article_115527_fba3e1efd17167af0a3f779755abefdb.pdf} }
