This thesis develops a machine learning framework to evaluate the capacity of FRCM-strengthened beams using beam mechanical and geometric properties, steel reinforcement details, and FRCM layer characteristics including number, type, mortar compressive strength, and thickness. Three separate ML models are trained for pre-peak, failure, and post-peak stages, then validated and reinforced with verified finite element models for robustness on unseen data.","Strengthening Beams using FRCM Machine Learning Approach  \nand Numerical Models  \nby  \nKambiz Daneshvar  \nA thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of  \nMaster of Applied Science  \nin  \nCivil Engineering  \nCarleton University  \nOttawa, Ontario  \nCopyright © 2023, Kambiz Daneshvar  \nAbstract  \nThe use of Fiber Reinforced Cement Matrix (FRCM) over traditional Fiber Reinforced Polymers (FRP) systems has gained attention due to FRCM's superior performance in various conditions. Despite the existing studies, predicting failure and post-peak behavior of FRCM has remained a challenge. This research leverages Machine Learning (ML) techniques to evaluate the capacity of FRCM-strengthened beams. This innovative approach addresses the limitations associated with both experimental and numerical models by providing a comprehensive model capable of predicting the response of FRCM-strengthened beams. The model considers various factors, including mechanical and geometric properties of the beams, steel reinforcement, and characteristics of the FRCM layers such as number, type, compressive strength of mortar, and thickness. A novel approach to employ ML is adopted to utilize three separate ML models to assess the beam capacity in pre-peak, failure, and post-peak stages. Following the ML model validation, verified Finite Element (FE) models are used to ensure the proposed model's robustness in handling unseen data.  \nKeywords: FRCM, Machine learning, Reinforced concrete beams; Numerical modeling  \nAcknowledgments  \nTo begin, I am deeply thankful for the unwavering support and guidance provided by my supervisor, Professor Hamzeh Hajiloo.
