Tests were made on 106 small-scale aluminium stanchions of I-section, loaded by an axial load P and one end moment M1 in the plane of the web; the slenderness ratios ranged between 27 and 79. For each slenderness the P-M1 relationship at collapse was well approximated by a parabola. G. Augusti and B. Barbarito
