Abstract: Background: This article presents a critical review of shear mechanisms in reinforced concrete beams,
addressing theoretical models, technical design codes, and influential parameters such as concrete compressive
strength (𝑓′𝑐), transverse reinforcement ratio ( w ) and arching action (𝑎𝑑
Materials and Methods: The literature review highlights the complexity of the phenomenon due to the material's
heterogeneity and the interaction of multiple mechanical factors.....
