Thin-walled cylindrical shells are extensively used in numerous kinds of industrial applications under different cases of load combination. Nonetheless, quite few are the experimental researches that point out the real behavior of cylindrical shells under pure bending and external pressure. In the present experimental study, the buckling behavior of long cylindrical steel shells was investigated under combined bending and uniform peripheral pressure. Relevant FE simulations were also carried out and the results were compared with the experiments. The study shows that the theoretical outcomes predicted by nonlinear finite element analyses agree acceptably with the experimental results in terms of bucking load and modes of deformation. Furthermore, it was found that the initial sectional out of circularity developed by bending (especially higher values) considerably influences the buckling capacity of such shells under uniform external pressure. Ultimately, an interaction formula was proposed to generalize the interaction behavior of the test results within the range of this study.
