    Detailing Aspects of the Reinforcement in Reinforced

    In reinforced concrete structures, detailing plays a vital role in how the structure behaves. Being a composite structure, the location of steel has significant influence on the stress distribution within the structure, and consequently on its behaviour. A poorly designed detail in reinforced concrete can result in localized stress
