This study aims at providing such pivotal knowledge necessary to better understand the behaviour of aluminium members through experimental investigations. With this objective, a comprehensive experimental study was performed to analyze the buckling behaviour of extruded aluminium members under compression with different section shapes, such as rectangular, square, I-shapes, and complex shapes. Overall, 14 stub column tests were performed and 24 cross-sectional tests under axial and eccentric compression are currently being conducted to investigate the local buckling behaviour of aluminium sections. In addition, 14 tensile coupon tests were carried out to further characterize the material response, and with also the intention of further using this data in accurate FE models. Also, initial geometrical imperfections in each specimen were measured mechanically as well as using 3D scanners. In order to investigate the buckling behaviour of aluminium members beyond experiments, the development of advanced non-linear shell numerical models is under way; the latter shall be validated through the measurements and results of the experimental study. Eventually, the results of the experimental and numerical studies shall enable developing a novel design approach for the prediction of the resistance of aluminium members, by means of the “Overall Interaction Concept”.
