This summary report is based on the experimental and numerical research of thin-walled cross-section’s compression resistance carried out in St. Petersburg State Polytechnical University. Current situation on the Russian market concerning the usage of cold-formed thin walled cross-sections is aimed at finding out a base foundation to start up a stipulation of the elements under discussion in the building industry. Some questions about the compression resistance of such cross-sections were raised at different conferences by scientific community and such companies as Arsenal ST, Baltprofile (Russia) and Rautaruukki Oyj (Finland). In this field a number of Doctoral theses have been defended during recent years in Russia (A.R. Tusnin, G.I. Belyy, I.V. Astakhov, D.V. Kuz'menko). Steel galvanized Cand U-profiles and thermo-profiles are the types of thin-walled cross-sections are normally used in small houses construction. Thermo-profiles have slots in webs that decrease the thermal flow through the web, but have negative effect on strength of the profiles. Reticular-stretched thermo-profile is a new type of thin-walled cross-sections that found its place on Russian market. These profiles were an object of the research. The carried out investigations included tests to prove the compression resistance of the thin-walled cross-sections. The compression tests as a result showed the behavior of stud’s profile under critical load. The specimen was compressed under various loads and deformation was recorded. In order to get buckling force a load-deformation diagram was plotted and analyzed. Analytical modeling of thin-walled cross-sections was done with contemporary analysis software (SCAD Office) using finite element method (FEM). During the modeling process the thin-walled profile based on shelland bar-elements were created and buckling analysis task showed good results.
