| Older bridges often incorporate reinforced concrete (RC) girders paired with non-composite concrete slabs. With time, these structures degrade due to aging, increased traffic loads, and environmental exposure, which compromises their load-carrying capacity. Strengthening these bridges by creating composite action between RC girders and slabs is a cost-effective approach to restoration. This study investigates using Carbon Fiber Epoxy Plates (CFEP) to reinforce bridge girders, aiming to improve their structural integrity and prolong service life. Full-scale RC beams retrofitted with CFEPs underwent rigorous testing to assess flexural and shear capacities under various loads. Additional simulations with ANSYS software provided further insights into interactions between RC girders and CFEPs. Results from both experimental and numerical analyses showed substantial increases in load capacity, stiffness, and reduced deflection in retrofitted beams. Fuzzy logic-based structural health monitoring enhances safety and maintenance protocols, providing real-time assessment. Findings from this research offer valuable design recommendations, proving CFEPs as an effective, economically beneficial solution for extending the lifespan of aging bridge structures while minimizing maintenance costs. | ||
