Annotation: In the article problems of designing and manufacturing of steel structures of I sections with a thin corrugated wall are discussed. By means of a method of final elements influence of initial imperfections, such, as local curvature and a deviation of parameters of corrugating, on stability of the thin corrugated walls of bent elements has been investigated. Models have been designed with the deformed scheme taking into account not elastic operation of steel. The basic theoretical positions realized in the personal computer LIRA of a method of problem solving in geometrically and physically nonlinear statement by means of FEM are resulted. The theoretical data is confirmed by results of natural tests. The received results have been used when working out specifications of manufacturing of welded double tee with a corrugated wall.
Keywords: a beam with a corrugated wall, a method of final elements, stability, initial imperfections.
Pages: 143-150.
