Annotation: On the basis of generalization of the results of mathematical modeling of the dynamic behaviour of the mechanical system «head-frame structures – a winder» a specification of spThe beams of 12 m long, web thickness is from 6 mm to 12 mm and web depth from 500 mm to 1000 mm, are analysed in this paper. The perforation diameter is selected from half of the web depth to the total web depth 100 mm minus. The cross-section area of two flanges was selected equal to the cross-sectional area of the web. The flanges thickness is equal two times the web thickness. Given beams have been loaded equally as for distributed load the upper flanges deformation are restrained out of plane. The general purpose of this work is to settle the critical shear stresses in the web wall and in this case it would lost the local stability. Calculations have been done using analytical formular and finite elements methods. Calculation results are represented compared with each other and are shown as charts.
