Abstract
The model for the analysis of compression of a long structure with a constant thin-walled cross-section is presented. It is assumed that a structure experiences static compression and the problem of initial stability for a cross- section is solved. The analysis of compression of a shell-type structure is described assuming that a structure undergoes static compression and the problem of initial stability is solved. The results of experimental investigation of resistance to compression of paperboard packages are presented for different grammage of the materials of paperboard and for the machine and cross-machine directions of production of paperboard. The largest permissible vertical pressure load that the packages are able to resist is determined
