Transition Key: 318‐11 to 318‐14Building Code Requirements for Structural ConcreteThe following chart is a mapping of provisons from ACI 318‐11 to ACI 318‐14 and ACI 318.2‐14. It is common that aprovision may have been divided or repeated. The code was mostly rewritten in the process of the reorganization; thus,the exact wording and context will not be the same at the new location.Also, the reorganization changed headings, introductions, scopes and pointers used in ACI 318‐11 that no longer work inACI 318‐14. Technical changes occurred that have altered or deleted requirements. The following symbols are used in theNote column to more easily indentify the type of change, if any:‡ Heading, scope statement, introduc on, or pointer to another sec on Technical changeBLANK Editorial or no changeChapter 1 ‐ GENERAL )NoteDescription‡Heading: Scope‡Heading: Concrete on steel deck‡Heading: Provisions for earthquake resistance‡Heading: Contract documents
