В России также начал проявляться повышенный интерес к практическому применению трубобетонных колонн (ТБК), особенно при проектировании высотных зданий. Данные конструкции обладают такими ценными качествами, как высокая прочность и пластический характер разрушения, обусловленный большими осевыми деформациями в предельном состоянии. В действующих нормативных документах по проектированию ТБК в России, а также за рубежом содержатся только указания по расчету их прочности на основании метода предельных усилий, а в таком расчете деформативные свойства конструкций не учитываются. Несущую способность необходимо определять не только с учетом ее прочности, но и с возможной необходимостью ограничения осевой деформации. Решению этой задачи на примере центрально сжатых элементов посвящено данное исследование.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Рассмотрен расчет прочности коротких ТБК в условиях центрального сжатия по методу предельных усилий. Известно, что осевые деформации трубобетонных колонн могут достигать слишком больших величин, неприемлемых для эксплуатационной пригодности несущего каркаса. Расчет производится с возможностью ограничения предельных осевых деформаций заранее определенной величиной.</p></sec><sec><title>Результаты</title><p>Результаты. Получена формула для установления осевых деформаций колонн в предельном состоянии по прочности, которые принимаются равными деформациям бетонного ядра при максимальных напряжениях. Проверка точности этой формулы выполнена по результатам сопоставлений вычисленных значений деформаций с опубликованными экспериментальными данными.</p></sec><sec><title>Выводы</title><p>Выводы. Полученные зависимости позволяют оценить деформативность рассчитываемой конструкции и расширяют область применения метода предельных усилий на трубобетонные элементы, в которых предельно допустимая деформация не превышает 25 % от деформации бетонного ядра при максимальном напряжении.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Compressed concrete tube elements have already earned a well-deserved place in global construction practice. In Russia, there has also been increased interest in the practical application of concrete tube columns (CTC), particularly in the design of high-rise buildings. These structures possess valuable qualities such as high strength and ductile failure due to large axial deformations in the ultimate limit state. Current design regulations for CTC in Russia, as well as internationally, only contain instructions for calculating their strength using the ultimate limit method, and this calculation does not take into account the deformation properties of the structure. Bearing capacity must be determined not only by considering its strength but also the possible need to limit axial deformation. This paper addresses this issue using centrally compressed elements as an example.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The strength calculation of short concrete tube columns under central compression using the ultimate limit method is considered. It is known that axial deformations of reinforced concrete columns can reach values that are unacceptable for the serviceability of the supporting framework. The calculation is performed with the option of limiting the ultimate axial deformations to a predetermined value.</p></sec><sec><title>Results</title><p>Results. A formula was derived for determining the axial deformations of columns in the ultimate limit state, which are assumed to be equal to the deformations of the concrete core under maximum stress. The accuracy of this formula was verified by comparing the calculated deformation values with published experimental data.</p></sec><sec><title>Conclusions</title><p>Conclusions. The obtained relationships allow us to estimate the deformability of the calculated structure and expand the scope of application of the ultimate stress method to reinforced concrete elements in which the ultimate allowable deformation does not exceed 25 % of the concrete core deformation under maximum stress.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>трубобетонная колонна</kwd><kwd>центральное сжатие</kwd><kwd>прочность</kwd><kwd>предельно допустимая деформация</kwd><kwd>деформация ядра при максимальном напряжении</kwd><kwd>метод предельных усилий</kwd><kwd>осевые деформации конструкции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>concrete filled steel tube column</kwd><kwd>axial compression</kwd><kwd>strength</kwd><kwd>ultimate allowable deformation</kwd><kwd>core deformation under maximum stress</kwd><kwd>method of ultimate forces</kwd><kwd>axial deformations of the structure</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bhure N.
