The presented method allows us to con sider the changes of cross sectional sizes, existence of repair stresses, tension imposing, resulting from the reinforcement of a structure. The calculation results illustrating features of tension of the strengthened ferro-concrete construction were given.</abstract><kwd-group xml:lang="en"><kwd>strengthening of constructions</kwd><kwd>ferro-concrete constructions</kwd><kwd>repair stress</kwd><kwd>variational method</kwd><kwd>elastic-plastic deformations</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>усиление конструкций</kwd><kwd>железобетонные конструкции</kwd><kwd>ремонтные напряжения</kwd><kwd>вариационный метод</kwd><kwd>упругопластические деформации</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Будин, А.Я.
