The aim of the study is to develop science-based methodology for estimation the values of the partial factors for design of steel structures for the conditions of the Republic of Belarus, taking into account the specified values of reliability levels. The object of the study is steel structural elements. Methods: mathematical modeling, numerical and analytical methods, parametric and graphic analysis. In January 2010 European standards (EN standards, Eurocodes) for the design, fabrication and erection of building structures were introduced in the Republic of Belarus. The system of European standards (EN 1990) recognise the responsibility of regulatory authorities in each country and guarantee their right to determine values related to regulatory safety matters at national level. According to the reliability concept of building structures adopted in the standard ISO 2394, EN 1990 the target reliability levels for designed structures are set. It caused a necessity to calibrate the partial factors of steel structures for Belarusian National Annex to Eurocode 3 based on the target reliability level using probabilistic methods.
