Different approaches in the design of slender aluminium alloy sections

The possibility of local buckling in members classified as slender is kept into account in the most up-to-date codes by replacing the true section with an effective one. This can be done via several approaches. In order to compare these approaches a comprehensive parametric analysis is presented in this paper, applying different design criteria to a set of sections which adequately represent the most important types of slender aluminium alloy sections. The obtained results allow one to check the reliability of the procedures proposed by the codes considering also the different computational cost required by each method.
