Prepared by the Stainless Steel Specification Committee of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCE
Specification for the Design of Cold-Formed Stainless Steel Structural Members, Standard ASCE/SEI 8-22, provides design criteria for the determination of the strength of stainless steel structural members and connections for use in buildings and other statically loaded structures. It is an update to ASCE 8-02 that aligns the design of cold-formed stainless steel structures with the latest findings in both stainless steel and carbon steel research and practice. It also provides requirements specific to stainless steel structures that greatly exceed those of typical carbon steel applications.
In the United States, hot-rolled stainless steel structural members that typically have no reductions from cross-section buckling do not have an approved standard. ASCE 8-22 reflects greater knowledge and adoption of cold-formed stainless steel structures worldwide in both applications and standards.
Major changes include adoption of format, provisions, and reliability indexes aligned with AISI S100-16; broader scope of stainless steel alloys and greater attention to the use of thin coil and sheet steel than the found in AISC 370; adoption of the use of initial modulus of elasticity and transverse offset stress; integration of new design methods, such as the direct strength method and the continuous strength method; and a summary of stainless steel alloys and properties to which this standard is applicable.
This updated standard has been adopted into the International Building Code.
The design strength requirements of this standard are intended for use by structural engineers and those engaged in preparing and administrating local building codes.
