EC9 Second Generation: Proposal for New Imperfection Factors for Unstiffened Aluminium Shells

Abstract:

The paper summarizes a part of the activity currently carried out by the CEN/TC250 SC9 Committee, which is presently engaged in setting up the “Second Generation” of EC9 on aluminium structures. In particular, new expressions of imperfection reductions factors α for unstiffened shells are proposed. The new formulation, which is calibrated on the basis of simulation buckling data available in literature, corrects a small issue of the previous one, giving at the same time more reliable and consistent results.
