The thin cylindrical shell structure under compression should be checked with buckling stability. In DNV, there is a spacing criteria of stiffener which based on linear theory without initial imperfection. In this study, structural analysis, using geometry nonlinear analysis, of stiffened cylindrical buckling strength with various initial imperfection were performed and compared with DNV and FEM results.
