Были испытаны на изгиб двухпролетные статически неопределимые железобетонные балки. Было проведено обсуждение результатов определения схемы разрушения, диаграммы прогиб-нагрузка, деформация-нагрузка и коэффициентов перераспределения моментов. Экспериментальные результаты были сравнены с аналитическими расчетами существующих моделей, включая нормы ACI 318-19 и CSA A23.3-19, и другие. Результаты показывают, что коэффициент перераспределения моментов в статически неопределимых железобетонных балках зависит от коэффициента армирования (μs1) и может быть более точно предсказан комплексным анализом. Результаты экспериментов также показывают, что коэффициенты перераспределения моментов испытанных балок превышают значения, предсказанные другими существующими моделями.</p></abstract><trans-abstract xml:lang="en"><p>This article investigates the coefficient of moments redistribution in statically indeterminate RC beams through an experimental and analytical approach. Two-span statically indeterminate RC beams were tested under bending moment. A discussion of the results of the mode of failure, load-deformation, load-strain, and the coefficient of the moments redistribution were conducted. Moreover, the experimental results were compared to the analytical predictions of the related existing models, including the ACI 318-19 and CSA A23.3-19 codes, and others. The results show that the coefficient of moment redistribution is affected by the reinforcement ratio (μs1) and can be accurately predicted by a recent mathematical analysis. The experimental results also reveal that the moment redistribution capacity of the beams exceeds the values predicted by the other existing models.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>статически неопределимые железобетонные балки</kwd><kwd>перераспределение моментов</kwd><kwd>экспериментальное исследование</kwd><kwd>теоретические модели</kwd><kwd>коэффициент армирования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>statically indeterminate RC beams</kwd><kwd>moment redistribution</kwd><kwd>experimental investigation</kwd><kwd>theoretical existing models</kwd><kwd>reinforcement ratio</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">Кальницкий А.А.
