Elastic shallow shell of translation subjected to the external pressure is analysed in the paper numerically by FEM. Nonlinear equilibrium paths are calculated for the different boundary conditions. Special attention is paid to the influence of initial imperfection on the limit load level of fundamental load - displacement path of nonlinear analysis. ANSYS system was used for analysis, arc - length method was chosen for obtain fundamental load - displacement path of solution.
