The IBC and AISC 303 Code of Standard Practice for Steel Buildings and Bridges
The Commentary in Section 1.1 of AISC 303-16 Code of Standard Practice for Steel Buildings and Bridges notes that some provisions in the Code have been incorporated by reference into the International Building Code (IBC). Here's how:
- Chapter 22 in the 2015 IBC incorporates both AISC 360-10 Specification for Structural Steel Buildings and AISC 341-10 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 AISC 360-10 and AISC 341-10 invoke certain requirements in AISC 303-10.
In AISC 360-10, the following references are made:
- Section A1 refers to the Code definition of structural steel in scoping the intent of the AISC Specification.
- Section A4 requires that structural design drawings and specifications shall 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 and 7.13 for fabrication and erection tolerances.
- Section N3 refers to Code Sections 4 and 4.4 for shop and erection drawing submittals.
In AISC 341-10, Section A1 invokes the requirements of AISC 360, which means all of the foregoing items also apply when AISC 341 is applicable. Also:
- Section A4.1 reiterates the requirement that structural design drawings and specifications shall meet the requirements in the Code.
- Sections I1.1 and I1.2 require that shop drawings and erection drawings, respectively, must meet the requirements of the Code.
- Chapter J makes several references to the foregoing Sections in Chapter N in AISC 360.
Currently, the 2018 IBC is being written. It is anticipated that the foregoing incorporations by reference of AISC 360-16 and AISC 341-16, and AISC 303-16 in turn will continue.
