The main stages of steel-restrained beams–purlins of the sloping roof for the typical metal frame with the initial geometric imperfections under the deformed scheme are considered. The restraint can occur, for example, by means of connecting to the steel beam light enclosing structures of warehouse space, namely profiled flooring. On the basis of a new approach to the analysis of internal power factors, it was aimed to find and describe the peculiarities of beam operation conditions under the joint action of the transverse bending in two planes and the warping torsion, which arises due to the eccentric laying of the load. The existing theoretical model has been improved by eliminating the shortcomings present in it. There has been carried out the comparison of techniques for determining bearing capacity by stability for flexible elements that are affected by bending and bending with torsion. Their advantages and disadvantages have been revealed according to the principles of simplicity and accuracy. It is proposed to increase material savings through a detailed calculation.
