Codes and Standards

The Code of Standard Practice for Structural Stainless Steel Buildings (AISC 313-21) provides a framework for a common understanding of the acceptable standards when contracting for structural stainless steel. Unless specific provisions to the contrary are contained in the contract documents, the existing trade practices that are contained therein are considered to be the standard custom and usage of the industry and are thereby incorporated into a contract between the related parties.

Design Guide 27, Structural Stainless Steel, provides guidance for the design of structural stainless steel. It is written for engineers experienced in the design of carbon steel structural components but not necessarily in the design of stainless steel structures, and is aligned with the design provisions in the 2010 AISC Specification for Structural Steel Buildings. It applies to the design of structural hot-rolled or welded open sections such as I-shaped members, channels, and equal-leg angles. It also applies to rectangular and round hollow structural sections (HSS). The guidance provided is applicable to austenitic, duplex and precipitation hardening stainless steel structural sections with thickness 1/8 in. (3 mm) and greater. Major topics covered are material behaviour and selection, cross-section design, member design, connections, and fabrication. Design Examples are also included.

When it comes to design, stainless isn’t just another grade of steel. AISC has published Design Guide 27: Structural Stainless Steel to help engineers learn more about the use of this material. This session will compare the mechanical and physical properties of stainless steels with those of structural carbon steels. Attendees will learn how to select an appropriate stainless steel alloy for a specific project, the principles of designing stainless steel members and connections, and the special design rules for stainless steel in the design guide. The session will also cover fire resistant design. Design examples and case studies will be used to demonstrate the differences between designing with structural carbon steel and stainless steel.

This two-part webinar provides an introduction to the design of structural stainless steel and the AISC Design Guide 27: Structural Steel Design.

Part 1, presented by Catherine Houska, includes the following topics:

• Brief history, performance, sustainability and applications for stainless steel as a structural material with references to specific projects
• Families of stainless steel used for structural sections
• Mechanical and physical properties compared to other metals
• Guidance on material selection for a range of environments
• Applicable ASTM specifications and AWS codes

Part 2, presented by Nancy Baddoo, includes the following topics:

• Unique properties of stainless steel that impact both design and fabrication
• Design rules given in AISC Design Guide 27 including how the design rules were derived
• Design of tension members, members in compression, members in flexure and shear, members subject to combined forces, and bolted and welded connections
• Design rules for structural fire resistance with comparison to the existing rules in the AISC Specification for carbon steel.

This resource provides the design criteria for the determination of strength of stainless steel members and connections used for load carrying purposes in buildings in Australia and New Zealand. Members can be cold formed to shape from annealed and cold rolled sheets, strips, plates or flat bar material. Mechanical properties are given in the annealed condition for austenitic grades (304, 316, 304L and 316L), ferritic grades (409 and 430), duplex grades (EN 1.4462) and the weldable structural steel grade (EN 1.4003). Based on test results of welded connections, an appendix is included which allows the nominal strength of tubular joints in CHS, SHS and RHS to be calculated using the provisions of Annex K of ENV 1993-1-1.

This document gives the clauses relating to stainless steel structures in EN 1090 Execution of steel structures and aluminium structures. Part 2: Technical requirements for the execution of steel structures with accompanying commentary. Additionally, it provides a set of optional and additional clauses that may be used in drawing up execution specifications for stainless steel structures, in conjunction with EN 1090-2, for individual projects. The clauses represent an industry ‘best practice’ view of how the general requirements of EN 1090-2 may be modified and supplemented, where permitted by that Standard, to achieve the quality and reliability to be expected for stainless steel structures designed in accordance with the Structural Eurocodes.
