This article addresses the issue of structural analysis using the light steel thin-walled designs based on Eurocode. The main reason for the insufficient use of structures fromLSTC in Russia is described. Some flexibility, coefficients and their values are given. Indicate the necessary types of checks for each design. The article contains information on the methods of joining elements from bent profiles of LSTC. It is also said about the types of design loads on the steel frame construction from profiles.
