Abstract
Despite a series of technological and service advantages compared to hot rolled structures, especially in certain fields, the use of cold formed structural elements now cannot be called intense. The main reason is insufficient knowledge about this kind of specific structural elements, features of work elements under load and the absence of normative documents. Introduction of Eurocode 3 in the Republic of Belarus played a favorable role in the implementation of effective constructive solutions on the basis of cold formed profiles. In the article emphasis is placed on the calculation of the effective cross-section characteristics, taking into account the platebuckling (traditional domestic term – local buckling) and distortional (cross-section) buckling. A comparative analysis of the methods of determining effective cross-section according to the requirements of Eurocode (EN 1993) and North American standards are carried out.
