In this work, calculations are made of the stability of a constant distribution loaded with an external distribution. Changes are considered, both of a smooth form and reinforced by a power set in the form of frames to reduce the load-bearing capacity. Imperfections in form were observed in the designs, which, one way or another, are present in existing structures. Pressure disturbances in these cases were found analytically and using the ANSYS Workbench FE package. The pressure values for shells with design features are determined.
