Exploiting the lightweight design potential of thin-walled shells requires precise buckling load predictions. Due to numerous scattering parameters affecting the buckling load, probabilistic approaches are often used to model these effects. However, developing a stochastic model requires test data while making some simplifying assumptions. In this contribution, the influence of different load deviation types on the buckling load of axially loaded cylindrical CFRP shells is investigated. It is shown that effects are direction-dependent and vary between types. The extent to which probabilistic approaches account for such effects is discussed. Finally, the results are transferred to other load cases and the importance of considering directional effects in design and testing is highlighted.
