В.А. Кучеренко. Для статистической обработки отобрана выборка из 41 годного испытания трех серий с единым конструктивным решением. Действующий СП 266.1325800.2016 «Конструкции сталежелезобетонные. Правила проектирования» не содержит частного коэффициента условий работы для рассматриваемых конструкций. По результатам обработки нормированный коэффициент несущей способности подчиняется нормальному закону, что подтверждено критериями Колмогорова–Смирнова и Шапиро–Уилка; коэффициент вариации составил 8,5%. Расчетное значение коэффициента условий работы по 5%-ному квантилю равно 1,15. В работе определено место предложенного коэффициента в действующей нормативной иерархии (СП 266 / СП 63 / СП 16 / ГОСТ 27751) и выполнено сопоставление с аналогичными коэффициентами по нормам Eurocode и AISC. Полученное значение обеспечивает требуемый уровень надежности рассматриваемых конструкций и может быть рекомендовано к включению в профильный раздел СП 266.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of a statistical analysis of the load-bearing capacity of steel-reinforced concrete coupling beams with external steel-plate reinforcement of monolithic linked walls of a high-rise building over 500 m tall, based on experimental research of 159 full-scale specimens of TsNIISK named after V.A. Kucherenko. For statistical analysis, a sample of 41 selected tests of three series with a common structural design was selected. The current Russian Code SP 266.1325800.2016 «Steel-reinforced concrete structures. Design code» does not specify a partial working conditions factor for the considered structures. The processing results show that the normalized load-bearing capacity coefficient follows a normal distribution, confirmed by the Kolmogorov–Smirnov and Shapiro–Wilk tests; the coefficient of variation amounted to 8.5%. The design value of the working conditions factor based on the 5%-quantile equals 1.15. The article establishes the place of the proposed factor in the current regulatory hierarchy (SP 266 / SP 63 / SP 16 / GOST 27751) and provides a comparison with analogous factors of Eurocode and AISC standards. The obtained value ensures the required level of reliability of the considered structures and can be recommended for inclusion in the relevant section of SP 266.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сталежелезобетонная конструкция</kwd><kwd>перемычка</kwd><kwd>листовое армирование</kwd><kwd>коэффициент условий работы</kwd><kwd>частный коэффициент по сопротивлению</kwd><kwd>статистический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>steel-reinforced concrete structure</kwd><kwd>coupling beam</kwd><kwd>steel-plate reinforcement</kwd><kwd>working conditions factor</kwd><kwd>partial resistance factor</kwd><kwd>statistical analysis</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">Motter C.J., Lehman D.E., Lowes L.N.
