In the presented paper, a rolled steel beam from the profile IPE 240 with slenderness ë=0.6 is being studied. One of the essential quantities which can be of significance for evaluation of a structure in a decisive manner, is the yield strength of the material. As the yield strength is, by its nature, a random quantity, its variability also influences the variability of the beam load-carrying capacity. The mutual correlation among individual elements of cross-section was considered. The correlation was introduced by using the so-called correlation lengths. The bar was modelled by applying the programme system ANSYS and by using the finite element SHELL 43. In addition to yield strength, also the randomness of the other imperfections (geometrical, structural) was considered. The problem is discussed in connection with design reliability conditions of the Eurocode 1, too.
