Abstract

The design of single angle columns requires the ability to predict their flexural-torsional buckling strengths and flexural buckling strengths about the minor principal axis. Present design code provisions are quite different. This paper presents close approximations for the elastic critical load of equal angle section columns. It is found that the member capacities are less than the minor axis capacity at low slenderness and almost remain constant. A formula of the balance point is proposed which is simpler and better understanding.

Keywords: Balance point, Elastic critical load, Single angle, Simplified equation.
