A Closer Examination of the Axial Capacity of Eccentrically Loaded Single Angle Struts

Abstract

The purpose of this article is to address the axial capacity evaluation of eccentrically loaded single angles. The focus will be to examine and expand on the axial capacity evaluation made in Example 3-8 of the 1993 LRFD Manual. The Example as presented did not illustrate the less conservative approach permitted by the Specification for Load and Resistance Factor Design of Single-Angle Members. The evaluation of the axial capacity with due consideration of the sign of the stress is addressed. Also, since the example is supposed to represent the capacity obtained by load from a gusset plate attached to one leg, an examination of this situation is made.
