Description	The present paper deals with an analysis of the influence of initial imperfections on the load carrying capacity of slender steel columns under axial compression. The variance of the load carrying capacity of a structure is influenced by the variance of input imperfections. The theoretical analysis is based on a geometrical and material non-linear finite element method; the steel structure is modelled using SHELL elements, the ANSYS program being applied. Sensitivity analysis is used to determine the sensitivity of strut load carrying capacity with respect to the variance of initial imperfections. The methodology based on Sobol' variance is used for the sensitivity analysis. Input imperfections are of random origin. Majority of the input imperfections were measured and their random realizations were computed using their histograms whilst employing the Monte Carlo method. The Monte Carlo method was applied in the evaluation of sensitivity indices.
