The numerical analysis results of flexible cylindrical shells stability in static unsymmet- rical loading cases are given in the article. Geometrically nonlinear shell theory relations were used in computational model development. Equilibrium paths are derived using finite differ- ence energy method and arch-length continuation procedure. Some results of flexible shallow cylindrical square shells analysis with various non-uniform out-of-plane load types are pre- sented in the article.
