The ACI 318-19(22), or the Building Code Requirements for Structural Concrete, is the leading standard published by the American Concrete Institute that establishes minimum requirements for the design and construction of structural concrete buildings. It covers materials, design principles, construction practices, and strength provisions to ensure safety, durability, and performance. Widely referenced by engineers, architects, and building officials, ACI 318 provides the framework for code compliance and is recognized as an essential resource for modern structural design in the U.S. and internationally.
