<p>Unlike conventional top-loaded beams, governed primarily by flexural or shear behavior, inverted T-beams (ITBs) are loaded on their flanges. Hence, critical flange–web interface stresses are developed causing separation and multiple local failure modes that are distinct from traditional strengthening categories. As such, hanger type reinforcement becomes fundamental in promoting the performance of these beams. The present literature lacks works that tackled the role of Near-Surface Mounted (NSM) Carbon Fiber Reinforced Polymer (CFRP) ropes in improving hanger resistance of inverted T-beams, in particular, the comparative performance of NSM and embedded-through-section (ETS) CFRP ropes’ configurations in rehabilitating pre-damaged inverted T-beams. For this, the effectiveness of CFRP ropes, as dowels, to enhance the hanger resistance of eleven ITBs purposely designed with deficient hanger capacity is investigated. ITBs were strengthened with NSM CFRP ropes at varying spacing, embedment lengths, and cross-sectional areas—with additional flexural strengthening using double CFRP sheets applied to selected specimens; others were reinforced with double ETS CFRP ropes at different spacing values. Two additional ITBs were preloaded to 50% and 70% of their ultimate capacity, before repaired using NSM CFRP ropes. Results showed that CFRP rope incorporation enhanced load resistance depending on the insertion method, configuration, and damage level, as well as the presence of CFRP sheets. The proposed systems improved load-carrying capacity and toughness by up to 36% and 32%, respectively. NSM systems outperformed ETS in hanger resistance but exhibited lower toughness and ductility. The influence of flexural CFRP sheets on ductility was configuration-dependent, with higher CFRP rope ratios improving separation ductility and energy absorption, while lower ratios produced only marginal or slightly reduced ductility.</p>
