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 303-16, 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 2018 IBC incorporate both ANSI/AISC 360-16, Specification for Structural Steel Buildings, and ANSI/AISC 341-16 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 360-16 and ANSI/AISC 341-16 invoke certain requirements in ANSI/AISC 303-16.
In ANSI/AISC 360-16, 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 360-16.
- Section A4 requires that structural design drawings and specifications meet the requirements in the Code.
- 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 6 for dimensional tolerances.
- Section M3.1 refers to Code Section 6 for painting requirements.
- Sections M4.1 and M4.2 refer to Code Section 7 for column base placement, erection tolerance, and temporary bracing requirements.
- Section N2 refers to Code Section 6.1 for material identification and Sections 6.4 and 7.13 for shop, fabrication and erection tolerances.
- Section N3 refers to Code Sections 4 and 4.4 for shop and erection drawing submittals.
ANSI/AISC 341-16, 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 A4.1 reiterates the requirement that structural design drawings and specifications meet the requirements in the Code.
- Sections I1.1 and I1.2 require that shop drawings and erection drawings, respectively, meet the requirements of the Code.
- Chapter J makes several references to the foregoing Sections in Chapter N in ANSI/AISC 360.
