Note: Always ensure you are accessing the most current version of the guide to match the latest ACI 318 building code requirements.

The American Concrete Institute (ACI) publishes standard practices that ensure the safety, structural integrity, and longevity of concrete structures worldwide. Among these, stands as a critical document for structural engineers, steel detailers, architects, and contractors.

The key shift is linguistic and conceptual. The old standard was largely prescriptive. The new guide provides “guidance,” meaning it shows examples of how to satisfy the provisions of modern codes like ACI 318-19, but it does not use mandatory language (e.g., “shall”) that can be directly cited in project specifications without modification.

Steel must transfer its load to the concrete effectively. The guide outlines how to detail:
