The verification of the design reliability of a steel element according to the concepts of standards EUROCODE 3 and EN1990 is presented in the article. Reliability is assessed by determining the failure probability, which is evaluated employing the Monte Carlo methodology. Reliability analysis enables the verification of reliability indices of the fore mentioned standards, generalization of obtained results and further development of design methods of structures according to the limit state theories. An overview of input random imperfections of steel structures whose histograms and statistical characteristics have been measured and monitored over a long time period is presented. The completeness of statistical information on input data for utilization in probabilistic studies is discussed. The quantification of uncertainty of statistical characteristics of hard to measure imperfections utilizing the fuzzy set theory is illustrated on a numerical example. The analysis of the influence of fuzzy uncertainty of input random variables on the fuzzy uncertainty of failure probability is presented. Uncertainty of computational models is discussed and modern instruments employable in the analysis of these uncertainties are listed. The analysis of the load carrying capacity of a steel plane frame with compression members is presented. Sobol’s sensitivity analysis was applied for the identification of the dominant imperfections.
