Three distinct ML models are developed through case studies, each trained with data generated from non-linear analyses performed in the finite element program DIANA FEA. Each case study seeks to optimise the developed models through various evaluation metrics and hyperparameter tuning. The objective is to explore the application of machine learning to the non-linear analysis of concrete structures and, simultaneously, gain a better understanding of these complex fields. All ML models in each case study are trained using beam parameters (beam length, height, width, and transverse and longitudinal reinforcement area) as input data and with measured  \nload/displacement from NLFEA in DIANA as output data. Case study 1 attempted to develop a model based on a binary classification algorithm that could predict bending or shear failure modes. Additionally, this case study determined that Sobol sampling is the most efficient sampling method for ML models in our case studies. Case studies 2 and 3 developed models based on regression algorithms. The model in study 2 could predict the peak load for an RC beam, while in study 3, it could predict the expected load/displacement graph for an RC beam. The developed ML models were evaluated using standard various evaluation metrics from machine learning. Some models from the case studies showed good results, especially after implementing hyperparameter tuning, while others needed further improvement. The models with good results exhibited low error measurements and predictions that were closely aligned with the true data values. However, after a final assessment of the models, it was clear that they had room for improvement. Enhancing the training dataset's quality and quantity would provide the much-needed information for the models. Exploring alternative hyperparameter tuning methods could also be beneficial in finding an optimal model fit. Implementing machine learning into the already complex field of non-linear analysis is challenging, but the models have shown promising results, which means they are worth further exploring.  \nRESPONSIBLE TEACHER: Daniel Cantero  \nSUPERVISOR(S): Daniel Cantero  \nCARRIED OUT AT: Department of Structural Engineering  \nPREFACE  \nThis master’s thesis marks the conclusion of our five-year studies in Civil and Environmental Engineering at the Norwegian University of Science and Technology (NTNU) .
