Экспериментами установлено, что при определенном конструировании прочность внецентренно сжатых элементов возрастает за счет работы композитной полимерной арматуры, расположенной в сжатой зоне сечения. Однако зависимости для расчета прочности внецентренно сжатых элементов, представленные в действующем своде правил по проектированию бетонных конструкций с композитной полимерной арматурой, не позволяют выполнить учет ее работы на сжатие, а потому требуют уточнения.</p><p>Цель исследования – разработка методики расчета прочности армированных композитной полимерной арматурой внецентренно сжатых бетонных элементов с учетом ее работы в сжатой зоне сечения.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Методика расчета прочности внецентренно сжатых элементов с учетом работы арматуры в сжатой зоне сечения разработана с учетом положений действующих норм проектирования и проверена данными экспериментальных исследований, выполненных отечественными и зарубежными исследователями.</p></sec><sec><title>Результаты</title><p>Результаты.

According to experimental data, at a certain design, the strength of eccentrically compressed elements increases due to the work of a composite polymer reinforcement located in a compressed cross-sectional area. However, dependences for calculating the strength of eccentrically compressed elements, represented in acting regulations for the design of concrete structures with a composite polymer reinforcement, appear to be inapplicable for calculating the reinforcement compression stress and, therefore, require refinement.</p></sec><sec><title>Aim</title><p>Aim. To develop a methodology for calculating the strength of eccentrically compressed concrete elements with a composite polymer reinforcement, considering the work of the latter in a compressed cross-sectional area.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Considering the work of a reinforcement in the compressed cross-sectional area, the methodology of calculating the strength of eccentrically compressed elements was developed taking into account the positions of current design standards and verified by the data of experimental studies performed by domestic and foreign researchers.</p></sec><sec><title>Results</title><p>Results. The results of methodology reliability tests were obtained using the experimental data of test samples with a carbon, glass, and basalt-plastic reinforcement of various profile types. During the calculation of eccentrically compressed elements using the proposed dependencies for calculating the height of an element compressed cross-sectional area, the accuracy and reliability were established to be comparable with those calculated according to dependencies adopted in current regulations for the design of concrete structures with a composite polymer reinforcement.</p></sec><sec><title>Conclusions</title><p>Conclusions. The proposed dependencies for calculating the height of a compressed cross-sectional area provide the sufficient accuracy of strength calculations for eccentrically compressed concrete elements both with and without taking into account the compression work of a composite polymer reinforcement. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>строительные конструкции</kwd><kwd>сжатые элементы</kwd><kwd>композитная полимерная арматура</kwd><kwd>прочность</kwd><kwd>методы расчета</kwd></kwd-group><kwd-group xml:lang="en"><kwd>building structures</kwd><kwd>compressed elements</kwd><kwd>composite polymer reinforcement</kwd><kwd>strength</kwd><kwd>calculation methodology</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">СП 295.1325800.2017 Конструкции бетонные, армированные полимерной композитной арматурой.
