"The paper deals with the fuzzy analysis of the cross-sectional area within the scope of reliable design of a steel bar. The paper describes the application of the theory of fuzzy sets as a tool in the modelling of uncertainty arising due to human activities. The fuzzy numbers of the geometrical characteristics were derived with respect to the tolerance limits of standard EN 10034 and results of experimental research. The fuzzy number of the cross-sectional area was evaluated according to the general extension principle. Results of the fuzzy analysis are compared with the histogram of cross-sectional area. The paper elaborates on technical knowledge in the field of reliability assessment and design of steel structures."@en . "Corfu" . . "26110" .
