Paper presents results from numeric analysis of stability of cylindrical steel shells under axial compression, in which except dents, out-of-roundness imperfections of substantial values were taken into account. Out-of-roundness in cylindrical silos, tanks and other steel structures is seldom and hard to eliminate in construction rising. Outcomes of undertaken analysis has shown that out-of-roundness imperfections with dimension twice as high as acceptable according to norm classes can have no significant influence on bearing capacity of axially compressed cylindrical steel shells. This conclusion can ease taking reasonable decisions in construction release to use. Keywords: shell stability; steel construction; geometry imperfections.
