Annotation: Residual stresses influence a structure stability and deformability. This influence is ambiguous, so, distribuation of residual sresses in the component sections is a problem of today. First of all it concerns the I-section components and a T-section of twin angles. A necessity of carrying out these investigations was due to the absence of recommendations on determining a residual stressed state in the normative documents and its accounting in designing compressed components. There has been developed a procedure of calculating the influence residual stresses on stability at their adjustment on a part of a component length by beading at the edges of belts in the middle part of a column length. There was fulfilled the first period of the computer-aided development of the calculation program which allows determining optimal parameters of the adjustment of residual stresses in I-section columns and estimating efficience quantitatively.
Keywords: residual stresses, column, stability, middle length.
