Кратко представлены результаты анализа отечественных и зарубежных нормативных документов по теме исследования. На основе обзора и обобщения результатов лабораторных испытаний узлов сопряжения плит с колоннами сформулированы факторы, оказывающие влияние на их прочность при сжатии. Описанные в статье численные исследования работы узлов типа «плита–колонна» выполнены с проведением предварительных верификационных расчетов, показавших хорошее совпадение с опытными данными по качественной картине разрушения и разрушающим нагрузкам. На основании результатов расчетов конечно-элементных моделей средних, крайних и угловых узлов «плита–колонна», в которых варьировались соотношения размеров колонн и толщин плит, их классов бетона по прочности при сжатии, а также действующего усилия на плиту и его предельного значения, предложены зависимости для расчета их прочности при сжатии.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the research work aimed at developing a methodology for calculating strength of reinforced concrete slab-columns joints made of different strength grade of concrete in monolithic frame of high-rise buildings. The results of Russian and foreign regulatory documents analysis and technical literature on this issue are briefly presented. On the basis of review and generalization of laboratory tests of slab-columns joints the factors influencing their compressive strength were formulated. Numerical analysis of “slab-column” type units’ behavior was carried out with preliminary verification calculations, which showed good accuracy with experimental data on fracture pattern and ultimate breaking loads. Based on results of calculations of finite element models of middle, extreme and corner slab-columns joints, which had a variation of ratios of column dimensions and slab thicknesses, strength grade of concrete, stress acting on the slab and its maximum value, the formulas for compressive strength analysis were derived.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>железобетонные конструкции</kwd><kwd>высотные здания</kwd><kwd>монолитный железобетонный каркас</kwd><kwd>стык плиты с колонной</kwd><kwd>узел «плита–колонна»</kwd><kwd>высокопрочный бетон</kwd><kwd>прочность</kwd><kwd>смятие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reinforced concrete structures</kwd><kwd>high-rise buildings</kwd><kwd>monolithic reinforced concrete frame</kwd><kwd>slab-сolumn connection</kwd><kwd>slab-column joint</kwd><kwd>high-strength concrete</kwd><kwd>strength</kwd><kwd>crushing</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 267.1325800.2016.
