The article is devoted to elaboration of the method of comparative analysis of steel corrugated web beams and I-section beams. For greater reliability of comparison beams with different width and thickness of the belts were considered. The comparison was carried out for 6 and 9 m spans at different values of load intensity. As a result of the study, graphs showing the dependence of normal stresses and metal content on the load value were obtained. The study allows to conclude that the efficiency of the application of corrugated web beams increases with increasing load, for small values of the distributed load, the forces in the usual profile will be less, but in all cases the corrugated web beams are more effecient in terms of metal content.
