scope:

Requirements for reinforcement are stated in Section 3.5.1 of ACI 318-08 as: "Reinforcement shall be deformed reinforcement, except that plain reinforcement shall be permitted for spirals or prestressing steel..." Deformed reinforcement is defined in Section 2.2 of ACI 318-08 as: "Deformed reinforcing bars, bar mats, deformed wire, welded wire reinforcement conforming to Section 3.5.3."

This report excludes discussion of structural steel, steel pipe, steel tubing, steel fibers, expanded metal, and fiber-reinforced polymers (FRP) and other nonmetallic reinforcement. This report describes these types of steel reinforcement in terms of availability and material properties, expressed in inch-pound units and metric units. The special requirements of ACI 349 and 359 are also discussed. American Association of State Highway and Transportation Officials (AASHTO) requirements (2002, 2004) are not discussed in this report because they generally follow ACI 318.
