Fuzzy Sets and Structural Engineering

This paper addresses the issue of uncertainty, with which we are often forced to work with whether we want to or not, in engineering. The article presents an alternate approach in the modelling of initial imperfections as fuzzy numbers. The evaluation of the load carrying capacity of a steel plane frame loaded at the columns is presented. The load carrying capacity was solved utilizing the geometric non-linear beam solution. The fuzzy analysis of the frame load carrying capacity is compared with the random load carrying capacity determined acc. to the LHS method based on real material and geo-metric characteristics and acc. to EUROCODE 3.
