columns." Technical Note, Engineering Journal, AISC, 28(3),

Abstract
The stiffness reduction factors given in Table A (page 2-8) of the first
edition of the LRFD Manual has an error that needs to be corrected. The
error occurs in adopting the technique originally proposed by Yura in
the context of ASD to LRFD.
