Steel pipes are studied considering external pressure, axial compression and bending actions to empty condition, taking into account the initial geometrical imperfections. The main objective is to study the behavior and structural stability of these pipes submitted to combine loads, considering the influence of the geometrical imperfections and to estimate the critical external pressure. Critical pressure of buckling, and modal configurations are evaluated by theoretical methods and numerical approaches such as finite element method (FEM). The numerical results are compared with theoretical results.
