The requirements for the interconnection of starred angle compression members contained in North American standards vary greatly from those of European standards. The North American standards, which require only one interconnector for any starred angle made with equal leg angles, are the most liberal. The British standard, on the other hand, is the most conservative.A theoretical study of "slender" starred angles indicates that the buckled shape changes when the number of interconnectors is increased from one to two. There is a corresponding increase in the critical load. The addition of more than two interconnectors has no significant effect on the critical load. An extensive experimental program verified these results. The experimental program also included starred angles that could be classed as being of "intermediate" length.The paper recommends that two interconnectors be used, one at each of the third points, in all starred angle compression members made with equal leg angles.
