Abstract: In the article is researched a question about additional efforts in steel farms from roll-formed and welded section (BWF) by series 1.460.3-23.98 on parameters of the is intense-deformed condition. Here are introduced plans examinations farms and results their calculations with consideration of geometrical imperfections. There was given an analysis of takings numerical research and recommendations by reduction value addition efforts in farms from BWF. The obtained values of extra effort and stress indicate that the initial imperfections affect the stress-strain state farms considered series. Results of theoretical calculation can be used during designing or working out of new similar designs from BWF. The account of the considered imperfection at a design stage allows rising in the following operational reliability of the considered designs. It is offered to develop a technique of the account of the basic initial imperfections as a part of universal settlement-graphic program complex Structure Cad.

Keywords: metal constructions, geometrical imperfections, technology of manufacture, MFE, intense- deformed condition, exactitude, numerical design.
