What material is placed in concrete to provide tensile reinforcement or used as tension members?

• A. Steel Cables
• B. Steel Bars
• C. Rebar Mesh
• D. Reinforcing Rods

Answer: (B)

Steel bars are placed in concrete to provide tensile reinforcement because concrete is strong in compression but weak in tension. When a member is loaded in bending or experiences cracking, the steel reinforcement in the tension zone carries the tensile stresses, keeping the member from failing. The two materials work together as a composite: concrete handles the compressive load while the steel bars take the tension, and a good bond between them (enhanced by deformed bars) ensures they act as a unit. Rebar mesh is also a form of reinforcement, mainly used to distribute loads over an area, but the primary material for resisting tension in standard reinforced concrete is steel bars (rebar). Steel cables are used in prestressed concrete to pre-tension or post-tension the member, which is a different technique from ordinary reinforcement. Reinforcing rods refer to the same concept as steel bars, but the common term used in practice is steel bars.
