Estimation of building metal structures imperfections on the basis of the fuzzy-set theory
Abstract: The article is devoted to the estimation of building metal structures imperfections. A structure gets imperfections in the processes of manufacture, transportation, erection and operation. The basic condition of guaranteeing the trouble-free operation of metal buildings and structures is diagnostics of technical conditions as a whole and available defects and damages in particular. The data about imperfections are obtained when inspecting buildings and structures. There is put forward the mechanism of estimating imperfections at their continuous accumulation. Estimation of technical conditions is based on the results of the primary expert judgement. There is suggested and substantiated a mathematical model of cumulative accumulation of imperfections on the basis of the fuzzy logic apparatus. Analysis of a constructive risk for each element is reduced to the comparison of design, valid and limiting values of the determining parameters. The apparatus offered allows estimating reliability of metal buildings and structures under operation.
Keywords: building metal structures, imperfections, reliability, fuzzy logic, constructive risk.
