The IBC and AISC 303 Code of Standard Practice for Steel Buildings and Bridges
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:
- 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.
- Similarly, IBC Chapter 17 incorporates these same two documents by reference for inspection requirements.
- 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.
