The article considers the methodology for structural analysis of reinforced under load open-section steel structure elements for strength with multi-parameter loading. In order to reduce the volume of calculations, the reverse course of solving the strength problem is proposed using the «Section» algorithm in dimensionless parameters. According to the limit state of the rod in the most loaded main section and given relative eccentricities, real acting forces are determined taking into account the elastic-plastic performance of the section.
