Classification and cross-section resistance of equal-leg rolled angle profiles

Abstract Angle profiles belong to the most common structural steel shapes used in construction. They exhibit specific features that distinguish them from other types of common sections. This paper presents specific rules for the classification of angle profiles as well as formulas for the design cross-section resistances. The rules are based on theoretical-analytical considerations and are subjected to extensive numerical validation. They are written in Eurocode 3 format so as to allow a direct possible inclusion in forthcoming drafts. They cover all cross-section classes and allow a smooth transition between them.
