In this paper, the results of modelling of compression test for the perforated thin-walled bars of very low slenderness are shown and confronted with the experimental results. Three sets of imperfections as well as a model without imperfections were analysed and compared. Application of initial imperfections improved the results in most cases, but not always in the same extent, there were also some cases, where they worsened the compliance with experiment instead.
