The Commentary in Section 1.1 of Code of Standard Practice for Steel Buildings and Bridges, ANSI/AISC 303-22, referred to as the Code, notes that some provisions in the Code have been incorporated by reference into the International Building Code (IBC). Here's how:

1. Chapters 22 and 35 in the 2024 IBC incorporate both ANSI/AISC 360-22, Specification for Structural Steel Buildings, and ANSI/AISC 341-22 Seismic Provisions for Structural Steel Buildings, by reference for design and construction requirements.
2. Similarly, IBC Chapter 17 incorporates these same two documents by reference for inspection requirements.
3. In turn, both ANSI/AISC 360-22 and ANSI/AISC 341-22 invoke certain requirements in ANSI/AISC 303-22.

In ANSI/AISC 360-22, the following references are made:

• Section A1 refers to Code Section 2.1 for the definition of structural steel in scoping the intent of ANSI/AISC 360-22.
• Section A4.1 requires that structural design documents and specifications issued for construction provide any fabrication and erection tolerances that are not included in or are different from the Code; it also requires that structural design documents and specifications issued for construction provide any requirements for approval documents in addition to what is specified in the Code Section 4.
• Section B8 states that the requirements of ANSI/AISC 360 are based on the assumption that dimensional tolerances provided in the Code are satisfied and requires the effects of larger tolerances to be considered if they are permitted.
• Chapter C (Section C2.2, specifically, and others) uses the Code erection tolerance to define the notional load used in the stability design; it also explicitly permits alternative notional loading when a different tolerance is used.
• Section M2.7 refers to Code Section 11 for dimensional tolerances.
• Section M3.1 refers to Code Section 6 for painting and surface preparation requirements.
• Section M4.1 refers to Code Section 7 for column base placement requirements.
• Section M4.2 refers to Code Section 11 for erection tolerance and temporary bracing requirements.
• Section N2 refers to Code Section 6.1 for material identification, Code Section 11.2 for shop fabrication tolerances, and Code Section 11.3 for field erection tolerances.
• Section N3 refers to Code Section 4.4 for fabrication and erection document submittals.

ANSI/AISC 341-22, Section A1, invokes the requirements of ANSI/AISC 360, which means all of the foregoing items also apply when ANSI/AISC 341 is applicable. Also:

• Section A4 requires that structural design documents and specifications issued for construction include items required in the Code.
• Sections I1.1 and I1.2 require that fabrication documents and erection documents, respectively, include items required by the Code.
