“…Compared with uniform loads, non-uniform loads are more common, which are resulted from liquid pressure, wind pressure, bending moment, discrete supports, boundary damage, non-uniformly loading, and so on. Chiba et al 15 employed the Galerkin method to consider the stability of circular shells under partial linear liquid pressure, and verified theoretical results by experimental tests. Shen 16 followed the boundary layer theory to analyze postbuckling behaviors of perfect and imperfect cylinders, which are under uniform axial compression and linear liquid pressure.…”

This paper focuses on the buckling problem of cylindrical shells under combined non-uniform axial compression and external pressure. To obtain buckling loads, a completely new method called two-parameter perturbation method is established. Using this method, governing differential equations are solved and buckling loads expressed by load functions, load parameters, and shell dimensions are derived for the first time. Comparative studies show that buckling loads by the analytical formulas coincide with those for combined uniform loads or single wind load in literatures. Buckling of a cylinder subjected to combined bending and wind loads is analyzed, and confirmed by the Galerkin method for the case of small load variations. Therefore, the presented formulas are adequately validated. The numerical calculations are carried out to analyze the effects of non-uniform load parameters on buckling load coefficient. The obtained results in this paper can be applied to evaluate buckling loads for cylinders subjected to combined non-uniform loads in actual engineering.
