Calculation of cold formed steel panels with double corrugations for for combined bending and axial compression

Cold-formed structures are used in buildings of various functional purposes: industrial, agricultural, sports. Interest in this kind of construction is growing, and this is due to the high speed of setting-up, low material consumption and, accordingly, the low cost of construction. Improvement and development of cold-formed structures in most cases is associated with the expansion of the range of profiles used in these structures, as well as with the development of new structural systems that provide an opportunity to increase the efficiency parameters of the structures. The introduction of the new code СП 260.1325800.2016 ‘Cold-formed thin-walled steel profile and galvanized corrugated plate constructions. Design rules’ became the basis for the development of such structures. But as long as this code does not fully cover all possible design forms and options for calculating the elements, that is why this article was prepared for the calculation of cold formed steel panels with double corrugations for combined bending and axial compression. During the work, an experiment was prepared and conducted with the aim of a combining a developed method of calculating existing panels, to methods of calculating according to СП 16.13330.2017. The article details the methodology of the experiment with a description of the assumptions that allow comparing the results of research with the actual work of the structure. The foundation was also laid for further scientific research on this topic.
