The transition from uncracked to cracked limit states in concrete structures requires precise minimum reinforcement to prevent sudden, brittle failure. However, as modern construction increasingly utilizes concrete matrices, significant discrepancies have emerged in how international building codes predict these critical safety thresholds. This thesis investigates the mechanical vulnerabilities and material inefficiencies inherent in current design frameworks by evaluating the minimum reinforcement area and non-dimensional reinforcement ratio across a comprehensive database of Lightly Reinforced Concrete (LRC) and Hybrid Reinforced Concrete (HRC) elements. The structural parameters of experimentally validated LRC elements are systematically evaluated against the theoretical provisions of five global standards: Eurocode 2004, Eurocode 2023, fib Model Code 2010, fib Model Code 2020, and ACI 318.
