Целью работы является определение степени влияния хомутов различной конфигурации, а также иных факторов, на длину хомута при различных размерах сечения линейного изгибаемого элемента. Полученные данные и зависимости позволяют получать наиболее эффективные решения армирования наклонных сечений минимальной стоимости. Расчетно-аналитический, основанный на анализе результатов расчетов при различных видах поперечного армирования, соотношения диаметров продольной и поперечной арматуры, величин защитного слоя, радиуса загиба хомута и размеров сечения. Предложено выражение для расчета действительной длины хомута в зависимости от размеров сечения, коэффициента армирования и толщины защитного слоя с учетом применяемых оправок. Получены графики, которые говорят об экономии длины хомута от 6,7-7,4%, при использовании рабочей арматуры Ø6, до 12,2-37,9%, при использовании рабочей арматуры Ø40, в диапазоне размеров сечения от 20×40 см до 55×80 см и при коэффициенте армирования 0,1%≤μ≤3%. Проанализированы зависимости уменьшения прочности в условиях неточной привязки рабочей продольной арматуры к хомутам. Полученные данные говорят об уменьшении прочности нормальных сечений балок от 0,33% до 10,78%. В работе рассмотрено влияние различных факторов при конструировании сечений линейных изгибаемых элементов на реальную длину хомутов в соответствии с принятыми нормами. Представленная работа уточняет расход поперечной арматуры для ее наиболее экономичного использования.</p></abstract><trans-abstract xml:lang="en"><p>The paper considers the influence of various factors on the actual length of clamps in the design of sections of linear bending reinforced concrete elements. The aim of the work is to determine the degree of influence of clamps of various configurations and other factors on the length of the clamp at various cross-sectional dimensions of a linear bending element. The obtained data and dependences make it possible to obtain the most effective solutions for reinforcing inclined sections with minimal cost. The calculation-analytical research method was used, based on the analysis of the results of calculations for  various  types of transverse reinforcement, the ratio of the diameters of the longitudinal and transverse reinforcement, the values of the protective layer, the radius of the bend of the clamp and the dimensions of the section. An expression is proposed for calculating the actual length of the clamp, depending on the dimensions of the section, the coefficient of reinforcement and the thickness of the protective layer, taking into account the mandrels used.Graphs of the change in the length of the collar for various section sizes b×h from 20×40 cm to 55×80 cm and with a reinforcement coefficient of 0.1%≤μ≤3% have been obtained. The graphs show savings in the length of the clamp from 6.7-7.4%, when using working fittings Ø6, to 12.2-37.9%, when using working fittings Ø40. The dependencies of strength reduction under conditions of inaccurate binding of the working longitudinal reinforcement to the collars are analyzed. The data obtained indicate a decrease in the strength of normal sections of beams from 0.33% to 10.78%. The paper considers the influence of various factors in the design of the sections of linear bending elements on the actual length of the clamps in accordance with accepted standards. Thanks to the obtained data and dependences, it is possible to refine the consumption of transverse reinforcement in beams for its more economical use.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>железобетонная балка</kwd><kwd>оправка</kwd><kwd>поперечная арматура</kwd><kwd>прочность наклонных сечений</kwd><kwd>прочность нормальных сечений</kwd><kwd>рабочая высота сечения</kwd><kwd>хомут</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mandrel</kwd><kwd>reinforced concrete beam</kwd><kwd>reinforcement clamp</kwd><kwd>strength of inclined sections</kwd><kwd>strength of normal sections</kwd><kwd>transverse reinforcement</kwd><kwd>working height of the section.</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">Tamrazyan А.G., Alekseytsev A.V.
