Application of uncertainty analysis to stability problems of steel-concrete structural members
The paper deals with the fuzzy analysis of the ultimate limit state of a steel strut with an encased web in compression. The first part of the paper lists presumptions required for the determination of the theoretical load carrying capacity for the column. Stresses in the concrete and steel section...

The paper deals with the fuzzy analysis of the ultimate limit state of a steel strut with an encased web in compression. The first part of the paper lists presumptions required for the determination of the theoretical load carrying capacity for the column. Stresses in the concrete and steel sections are determined according to the principles of elasticity. The ultimate limit state is given as the limit stress attained in the most stressed section of either the steel or concrete section. A general extended principle, which takes into account the epistemic uncertainty of input parameters, was utilized for the conducted analysis.
Neapibrėžtumo analizės taikymas plienbetonio konstrukcinių elementų stabilumo uždaviniuose
Santrauka
Straipsnyje nagrinėjamas plienbetonio konstrukcinių elementų stipris remiantis fuzzy analize. Pirmoje straipsnio dalyje aprašomos prielaidos, reikalingos teoriniam kolonos laikomosios galios nustatymui. Itempiai plieniniuose ir betoniniuose skerspjūviuose nustatomi pagal tamprumo teorijos principus. Ribinis pavojingiausio pjūvio būvis pasiekiamas tada, kai įtempiai pasiekia ribinių įtempių reikšmes plieno apvalkale arba betono užpilde. Analizei buvo pasitelktas išplėstinis principas, kuris įvertina pradinių parametrų „epistematinį“ neapibrėžtuma.
