AISI-Specifications for the Design of Cold-Formed Steel Structural Members

Alternative Title

AISI COFS PM-2001 Prescriptive Method Standard 2001(with 2004 Errata)


The material contained herein has been developed by the American Iron and Steel Institute Committee on Framing Standards. The Committee has made a diligent effort to present accurate, reliable, and useful information on cold-formed steel framing design and installation. The Committee acknowledges and is grateful for the contributions of the numerous researchers, engineers, and others who have contributed to the body of knowledge on the subject.

With anticipated improvements in understanding of the behavior of cold-formed steel framing and the continuing development of new technology, this material may eventually become dated. It is anticipated that AISI will publish updates of this material as new information becomes available, but this cannot be guaranteed.

The materials set forth herein are for general purposes only. They are not a substitute for competent professional advice. Application of this information to a specific project should be reviewed by a design professional. Indeed, in many jurisdictions, law requires such review. Anyone making use of the information set forth herein does so at their own risk and assumes any and all liability arising there from.

The user is advised to check the availability of specific framing material in the region in which the dwelling is being constructed. Not all material specified in this Prescriptive Method is expected to be available in all locations. The load and span tables contained in this Prescriptive Method specify either 33 ksi (230 MPa) steel or 50 ksi (340 MPa) steel. It should be noted that 50 ksi (340 MPa) steel members might not be available in 33 mil (0.84 mm) and 43 mil (1.09 mm) thicknesses. The user is advised to check with the supplier for availability.
