Rebar

Definition

Rebar, or reinforcing steel, is cast into concrete to develop more structural capacity.

Purpose

The purpose of rebar is to reinforce concrete, which is strong in compression but weak in tension, by adding tensile strength and improving its overall structural performance.

Examples of Use

• Rebar is used in the construction of reinforced concrete beams, columns, and slabs in buildings.
• In bridge construction, rebar reinforces the concrete deck and supports to handle dynamic loads and environmental stresses.
• Foundations and retaining walls incorporate rebar to ensure stability and resistance to cracking under load.

Related Terms

• Reinforced Concrete: Concrete that is strengthened with rebar or other reinforcement materials.
• Tensile Strength: The resistance of a material to breaking under tension.
• Structural Capacity: The ability of a structure to support loads without failing.

Notes

Proper placement and securing of rebar are crucial for the effectiveness of reinforced concrete, requiring precise engineering and construction techniques.
