In the article, numerical studies are performed to assess the stress-strain state of the wall of a steel beam with an I-beam symmetrical cross-section. The determination of internal forces and stresses is performed in the SCAD Office computing complex. A new method is proposed for estimating the average stress values in the wall, taking into account the uneven distribution of stress over the area of the wall section where local stability is evaluated. Based on the results of calculations, stress plots and mosaics are constructed, showing their spatial distribution of stress on the controlled sections of the beam wall compartments. Analysis of the research results showed that the most appropriate application of the proposed approach is in areas with uneven distribution of beam stresses, especially in the support sections of the wall.
