The proofs of the theorems show that all theorems depend on the linear superposition of load cases to form load combinations. If the behavior of the structure becomes geometrically nonlinear because it is affected by large displacements, load cases can no longer be superimposed. New concepts are therefore required for the limit and shakedown analysis of structures with significant geometric nonlinearity.</abstract><trans-abstract xml:lang="ru">В данной работе приведен обзор существующих теорем, позволяющих определить предельные нагрузки и нагрузки приспособляемости стальных конструкций при малых перемещениях путем решения задачи оптимизации. В ней показано, что все рассмотренные теоремы используют принцип линейной суперпозиции для формирования сочетаний нагрузок. Если поведение конструкции становится геометрически нелинейным вследствие больших перемещений, то суперпозиция нагрузок становится невозможной. Сделан вывод о невозможности использования теорем о приспособляемости и, как следствие, основанных на них методов оптимизации, при расчете конструкций со значительной геометрической нелинейностью</trans-abstract><kwd-group xml:lang="en"><kwd>steel structures</kwd><kwd>plasticity</kwd><kwd>shakedown</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>стальные конструкции</kwd><kwd>пластичность</kwd><kwd>приспособляемость</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Качанов Л.М.
