General requirements, identification and connections

Introduces the CBC rules on scope, marking and testing of components, and the design/inspection requirements for connections (notably § 2201.2–.5 and Section 1705).

Last reviewed: July 5, 2026

Overview

This hub covers the CBC provisions that set baseline quality, identification and connection rules for building components — especially in structural steel chapters where these topics are grouped as general requirements. The CBC establishes scope and application at § 2201.1 and then spells out identification, protection and connection obligations (see § 2201.2 Identification; § 2201.4 Connections) for steel members and related elements . Those provisions require conformity with referenced standards (ASTM, AISC, AWS, etc.) and tie component marking and testing to the applicable referenced documents and Chapter 17/17A quality-control rules .

Why it matters: correct identification, durable protection and properly designed/installed connections are fundamental to structural performance, inspection and code enforcement — for example, anchor setting and thread engagement rules are addressed explicitly at § 2201.5, and special inspection requirements for welding and high‑strength bolting are coordinated with the special inspection program in Section 1705 . Use this hub to find the primary CBC sections that orient design, fabrication, marking and inspection for components and their connections.

    2201 A .2 Identification. Identification of steel members shall be in accordance with the applicable referenced standards within this chapter. Other steel furnished for structural load-carrying purposes shall be identified for conformity to the ordered grade in accordance with the specified ASTM standard or other specification and the provisions of this chapter. Where the steel grade is not readily identifiable from marking and test records, the steel shall be tested to verify conformity to such standards. [DSA-SS] All material iden- tification and testing shall be in accordance with Chapter 17A.

    2201 A .3 Protection. The protection of steel members shall be in accordance with the applicable referenced standards within this chapter.

    2201 A .4 Connections. The design and installation of steel connections shall be in accordance with the applicable referenced standards within this chapter. For special inspection of welding or installation of high-strength bolts, see Section 1705 A .2.

    2201A.4.1 Restrained welded connections. [OSHPD 1 & 4] Welded structural steel connections having a medium or high level of restraint, as defined by AWS D1.1 Annex H, shall have a minimum pre-heat temperature of not less than 150 [o] F (66 [o] C). Welded struc- tural steel connections with welds to flange, web, wall or plate having a high level of restraint shall maintain a post-heat temperature of 300 [o] F (149 [o] C) for a minimum of 1 hour after completion of welding.

    2201 A .5 Anchor rods. Anchor rods shall be set in accordance with the approved construction documents. The protrusion of the threaded ends through the connected material shall fully engage the threads of the nuts, but shall not be greater than the length of the threaded portion of the bolts. 2201A.5.1 Shear transfer at column base plate. Where the holes in column base plates are more than [1] / 8 inch (3 mm) larger than the anchor rods, as permitted by AISC 360, the anchor rods shall be designed for the induced bending stresses in combination with axial and shear stresses. Alternatively, shear lugs designed in accordance with ACI 318 Section 17.11 shall be permitted to transfer shear forces between column base plates and the supporting structure.

    SECTION 2202 A —STRUCTURAL STEEL AND COMPOSITE STRUCTURAL STEEL AND CONCRETE

    2202 A .1 General. The design, fabrication and erection of structural steel elements and composite structural steel and concrete elements in buildings, structures and portions thereof shall be in accordance with AISC 360.

Frequently asked questions

What does “identification” require for steel members?

Identification requires that steel and other load‑carrying materials be marked and documented to show conformity to the ordered grade and referenced standards; where marking or records are insufficient, testing is required to verify conformity (see § 2201.2) .

When do connection details trigger special inspection?

Design and installation of steel connections must follow the applicable referenced standards, and welding or high‑strength bolt installation that requires special inspection is coordinated through Section 1705 (special inspections for structural steel and seismic systems) as referenced in § 2201.4 and § 1705 .

Where are anchor‑rod requirements stated?

Anchor‑rod setting and threaded engagement requirements are contained in § 2201.5, which directs setting in accordance with the approved construction documents and limits protrusion and engagement of threaded ends .
