Originální abstrakt

In this article, deformations of an I-section steel beam under equal end moments are studied. An initial geometric imperfection of the beam axis according to Eurocode standard is applied. Former numerical studies showed that the lateral deflection of slender beam under major axis bending can be relatively high. The acceptability of high values of lateral deflections within the framework of serviceability limit state is discussed. In the next part of the paper, the limit value of maximum deflection was introduced as a fuzzy number. The fuzzy analysis of the maximum moment which causes the maximum deflection was carried out. The slendernesses of beams for which the serviceability limit state is the limiting state for design were identified.
