000001939 520__ $$2eng$$aThe 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 analysis is used for the determination of the probability of failure, which is evaluated using the Monte Carlo methodology. Reliability analysis presents a valuable tool for the verification of reliability indices of the fore mentioned standards, generalization of evaluated results and further development of design methodology of structures according to the limit state theories. The article presents an overview of random input imperfections of steel structures whose histograms and statistical characteristics have been monitored and measured over a long time period. The completeness of statistical information on input data for the purpose of utilization in probabilistic studies is discussed. The quantification of uncertainty of the statistical characteristics of difficult to measure imperfections utilizing the theory of fuzzy set is illustrated on a numerical example. The analysis of the influence of fuzzy uncertainty of random input variables on the fuzzy uncertainty of failure probability is presented. Uncertainty of computational models is discussed and modern instruments utilizable 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.
