The influence of scattering input parameters on the response of axially compressed stiffened composite panels is investigated. In order to estimate the stochastic distributions and the correlations between the first buckling load (or local buckling load), the global buckling load and the collapse load, a semi-analytic probabilistic analysis is performed. A procedure is given for evaluating the probability of failure of stiffened panels from the determined stochastic distributions, and probabilistically justified safety factors are derived.
