The objective of the presented paper is the ultimate limit state sensitivity analysis of a steel plane frame to input imperfections. The Sobol's variance based strategy was applied for the sensitivity analysis evaluation. The ultimate limit state was solved by the geometrical nonlinear finite element solution. The load-carrying capacity, solved on behalf of the Monte Carlo numerical simulation method, was the output random quantity. Input imperfections were measured, and their histograms have been applied in the Monte Carlo method. In the paper, there are demonstrated the changes of sensitivity coefficients in dependence on system lengths of columns.
