AISI publishes new research report on cold-formed steel

The American Iron and Steel Institute (AISI) has published a new research report, “RP23-01: Analytical Equations for Critical Local Buckling Stress of Lipped Channels.” The report provides analytical equations for calculating the critical load buckling stress of lipped channels with or without punchouts under compression and bending.

The research was funded by AISI and the Steel Framing Industry Association and performed under the Cold-Formed Steel Research Consortium. The report is available for free download in the AISI Design Resources section at www.buildusingsteel.org.
