Reinforced Concrete

Definition

Reinforced concrete is concrete containing adequate reinforcement (prestressed or not prestressed) and designed on the assumption that concrete and steel act together in resisting forces. It involves concrete work into which steel bars have been embedded to impart tensile strength to the member.

Purpose

The purpose of reinforced concrete is to enhance the tensile strength of concrete structures, which are inherently strong in compression but weak in tension. The combination of concrete and steel reinforcement creates a material that can withstand various structural loads and stresses.

Examples of Use

• In high-rise buildings, reinforced concrete is used for columns, beams, and slabs to support significant loads.
• Bridges use reinforced concrete for decks and supports to handle traffic and environmental stresses.
• Foundations and retaining walls often employ reinforced concrete to ensure stability and durability.

Related Terms

• Prestressed Concrete: Concrete in which internal stresses are introduced to counteract tensile stresses.
• Steel Rebar: Steel bars embedded in concrete to provide tensile strength.
• Structural Member: An individual part of a building's structure, such as a beam or column.

Notes

Reinforced concrete must be properly designed and installed to ensure the steel reinforcement effectively enhances the concrete's tensile capacity, ensuring structural integrity and safety.
