Charts are presented for the calculation of the critical stress for local instability of columns with I-, Z-, channel, and rectangular-tube section. These charts are intended to replace the less complete charts published in NACA Technical Note No. 743. The values used in extending the charts are computed by moment-distribution methods that give somewhat more accurate values than the energy method previously used and also make it possible to determine theoretically which element of the cross section is primarily responsible for instability.
