При расчете по данному методу используются реальные диаграммы деформирования материала под нагрузкой. Использование данного метода для расчета железобетонного элемента в сечениях с механическими стыками арматуры обусловливает необходимость проведения экспериментальных исследований для уточнения особенностей совместной работы бетона с арматурой в местах установки стыков. В частности, необходимо исследовать особенности деформирования механических соединений арматуры совместно с бетоном при циклическом режиме нагружения. Данные вопросы рассматриваются в предлагаемой статье. Приводятся методики и результаты экспериментальных исследований работы арматурного проката класса А500С и механических соединений арматуры на конической резьбе в свободном состоянии и при совместной работе с высокопрочным бетоном класса В60. Исследованы два режима нагружения – статическое растяжение и многоцикловое растяжение. Выявлены особенности работы механических соединений арматуры на резьбе при указанных режимах нагружения с учетом влияния сцепления с бетоном. Полученные результаты экспериментальных исследований являются основой для развития диаграммного метода расчета железобетонных конструкций в сечениях с механическими соединениями арматуры.</p></abstract><trans-abstract xml:lang="en"><p>The diagrammatic calculation method is used in the calculation of reinforced concrete structures for the most accurate modeling of its stress-strain state. When calculating using this method, real diagrams of material deformation under load are used. The use of this method to calculate a reinforced concrete element in sections with mechanical connections of reinforcement necessitates experimental studies to clarify the features of the joint work of concrete with reinforcement in places where mechanical connections are installed. In particular, it is necessary to study the features of deformation of mechanical connections of reinforcement together with concrete during cyclic loading. These issues are discussed in the proposed article. The methods and results of experimental studies of the operation of rebar rolled products of class A500C and mechanical connections by conical threads in a free state and when working with high-strength concrete of class B60 are presented. Two loading modes have been studied – static stretching and multi-cycle stretching. The peculiarities of the operation of mechanical connections by threads under the specified loading conditions, taking into account the effect of adhesion to concrete, are revealed. The experimental research results obtained are the basis for the development of a diagrammatic calculation method for reinforced concrete structures in sections with mechanical reinforcement connections.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>арматура</kwd><kwd>бетон</kwd><kwd>механическое соединение арматуры</kwd><kwd>циклическое нагружение</kwd><kwd>диаграммный метод расчета</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reinforcement</kwd><kwd>concrete</kwd><kwd>mechanical connection of reinforcement</kwd><kwd>cyclic loading</kwd><kwd>diagram calculation method</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">Liang J., Nie X., Masud M., Li J., Mo Y.
