| Summary: | This study aims to minimize the expensive experimental testing of unique boltless steel connections using the prediction power of several computational techniques. Thirty-two tests were conducted on boltless steel connections using double-cantilever test method and their results were compared with developed models using Artificial Intelligence (AI) techniques. Linear Genetic Programming (LGP), Artificial Neural Networks (ANNs) and Adaptive Neuro Fuzzy Inference System (ANFIS) were applied to predict the moment-rotation (M-θ) behavior of boltless steel connections. The predictive performance of the models was assessed by comparing the values of co-efficient of determination (R2), mean square error (MSE) and root-mean-square error (RMSE). The LGP model well predicted the M-θ behavior as compared to the other models. The robustness of the LGP model was further proved by performing different statistical tests. |
