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.　©　Zhang　et　al.
