Original Abstract

The analysis of the influence of stochastic and fuzzy uncertainties of imperfections on the stochastic and fuzzy uncertainties of the load-carrying capacity of a steel plane frame is presented. On a simple example of a steel plane frame, the analyses of the possibilities of system imperfections implementation as random variables are performed. The influence of uncertainty of random characteristics of the correlation coefficient between the random initial inclinations of the frame columns on the load-carrying capacity of the frame is studied. In the next stage, the system imperfections are considered as fuzzy numbers. The fuzzy load-carrying capacity was determined as a fuzzy number, utilizing the general extension principle. The comparison of fuzzy and stochastic load-carrying capacity with the design standard load-carrying capacity acc. to EUROCODE 3 is performed in the final stage.
