Abstract

The aim of the work is a qualitative and quantitative comparison of the results of analysis of stability of the steel section girder framework I-beam, aligning the frame elements and rod elements of the coating, using a finite element method. The advantage of sheet metal cross-sections is the ability to freely select the thickness of the component sheets; the use of rigid belts and slender webs gives the most efficient use of the cross-section load capacity. The plate girders show a large supercritical load capacity during bending, the breaking loads for this type of plate girders can be significantly higher than the critical loads.
