DIFFERENT APPROACHES IN THE DESIGN OF SLENDER ALUMINUM-ALLOY SECTIONS

The possibility of local buckling in members classified as slender is kept into account in the most lip-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 anal ysis 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 t o check the reliability of the procedures proposed by the codes consid ering also the different computational cost required by each method.
