Applicability of Fuzzy Logic to the Definition of the Buckling Length of Steel Plane Frames

Original language description

The aim of the study was to analyse the influence of uncertainty of joint stiffness on the uncertainty of buckling lengths of both columns. The input stiffness and output buckling length are considered as fuzzy number. Generally, engineering procedures employed in the design of load-bearing structures of building objects are essentially based on computational procedures that verify valid normative criteria emanating from the static, respectively the dynamic solution of a model of the real structural system. The paper illustrates the modelling of the vague uncertainty of statistical characteristics of kurtosis of the amplitude of initial curvature utilizing fuzzy numbers. The processes of fuzzification, fuzzy analysis (including the utilization of the general extension principle) and defuzzification are described. Fuzzy analysis enables the verification of reliability indices of the fore mentioned standards, generalization of obtained results and further development of design methods of
