Name two primary codes/standards that govern reinforced concrete design in the U.S.

• A. ACI 318 and ASTM standards (A615/A706 for rebar)
• B. FEAM 400 and ISO 9001
• C. ASME B31.3 and NFPA 70
• D. ANSI Z535 and PCI 600

Answer: (A)

In reinforced concrete design in the United States, you rely on a design standard for the concrete member and material standards for the reinforcement. The primary design standard is ACI 318, which lays out the rules for designing concrete members, including strength, serviceability, detailing, and how to handle load combinations. For the reinforcement itself, the properties and testing requirements are defined by ASTM standards A615 and A706, which specify the material type, yield strength, ductility, and weldability of reinforcing bars. This pairing—ACI 318 for design and ASTM A615/A706 for rebar material—forms the backbone of how reinforced concrete is engineered in the U.S. and is widely adopted by model building codes. The other options relate to entirely different disciplines or specialized areas, not the standard approach to general reinforced concrete design.
