摘要

This paper assesses the eight buckling analyses presented in Eurocode 9 for thernDesign of Aluminium Shell Structures. The assessment was based on a fictionalrndesign brief for a medium length thin aluminium cylindrical shell under uniformrnaxial compression. The research concluded that the use of numerical analysis wasrnessential to achieve efficient design. Although quick methods are presented inrnEurocode 9 to determine buckling stresses, this research found that the quick methodrnresults lead to an overestimation of the buckling resistance. Geometrically andrnmaterially non-linear analysis with imperfections is recommended.
