The performance of reinforced concrete beams under various loading conditions is critically influenced by their reinforcement ratio, which affects their strength, ductility, and overall structural behavior. This study presents a comprehensive numerical modeling approach using nonlinear finite element analysis (FEA) to investigate the impact of different reinforcement ratios on the behavior of reinforced concrete beams. By employing advanced FEA techniques, the research explores the deformation patterns, failure mechanisms, and load-bearing capacities of beams with varying reinforcement configurations. The study incorporates detailed material models and considers nonlinear interactions between concrete and reinforcement to capture the complexities of real-world behavior. Results reveal significant variations in beam performance with changes in reinforcement ratio, highlighting the importance of optimizing reinforcement for both safety and efficiency. The findings provide valuable insights for structural engineers in designing reinforced concrete beams that balance strength and ductility, ultimately contributing to more resilient and cost-effective construction practices.
