AISI Publishes Report on LRFD and LSD Resistance Factors for CFS Compression Members
WASHINGTON, D.C. – The American Iron and Steel Institute (AISI) has published a new research report on the recalibration of the Load and Resistance Factor Design (LRFD) and the Limit States Design (LSD) resistance factors for cold-formed steel compression members when the strength is predicted using the Direct Strength Method. Since the Direct Strength Method statistically provides a better strength prediction, higher resistance factors are realized. A summary of the project, findings and analys...

In addition, as the only I-Code that more than pays for itself in “real dollar” energy bill savings, the IECC’s “whole-house” efficiency mea...
