Annotation: The residual stresses effect upon stability and ability to deform of the structures. This influence is ambiguous, so the problem of distribution of residual stresses in sections of elements may be regarded as urgent. In the first turn it concerns the elements with sections made of compressed welded double-tee profiles, tee sections of double angles and straight-seamed electrically welded pipes. It was proved experimentally a reduction of critical forces for compressed welded double-tee elements because of availability in chords the remaining compressive stresses and increase of critical forces for compressed elements made pipes after buttering under the angle 120 degrees. The necessity of making of the present researches has arisen in connection with an absence in normative reference sources the recommendations for determination of parameters of residual stressed state and its taking into consideration during calculation of compressed elements made of pipes.
Keywords: residual stresses, straight-seam electrically welded pipes, stability.
