Моделирование конструкций выполнено с использованием объемных конечно-элементных моделей в программном комплексе «ЛИРА-САПР». Исследования проведены для образцов 4 видов, различающихся между собой габаритами в плане и армированием. Дано подробное описания использованных зависимостей и законов деформирования материалов в ходе построения моделей. Сравнительному анализу подверглись величины сжимающих напряжений в бетоне и арматуре, а также растягивающих напряжения в арматуре, полученные в результате моделирования. На основе проведенного исследования установлено, что использование несъемных пустотообразователей в монолитной железобетонной плите не снижает ее прочность, при этом позволяет сократить расход бетона на 18,3÷23,1 %.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of a numerical experiment to determine the effect of non-removable void generators on the strength of monolithic reinforced concrete floor slabs clamped along the contour. The experimental samples are made in the form of spatial models using volumetric finite element models in the LIRA-CAD software package. The tests were carried out on 4 series of samples, differing in terms of dimensions and reinforcement. Detailed descriptions of the dependencies used and the laws of deformation of materials during the construction of models are given. The values of compressive stresses in concrete and reinforcement, as well as tensile stresses in reinforcement obtained as a result of tests, were subjected to comparative analysis. Based on the conducted experiment, it was found that the use of non-removable voids in a monolithic reinforced concrete slab does not reduce its strength, while reducing concrete consumption by 18.3-23.1%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>железобетон</kwd><kwd>монолитная плита</kwd><kwd>плита с пустотообразователями</kwd><kwd>прочность</kwd><kwd>численное моделирование</kwd><kwd>конечно-элементная модель</kwd><kwd>программный комплекс «ЛИРА-САПР»</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reinforced concrete</kwd><kwd>monolithic slab</kwd><kwd>slab with voids</kwd><kwd>strength</kwd><kwd>numerical modeling</kwd><kwd>numerical experiment</kwd><kwd>non-removable voids</kwd><kwd>finite element model</kwd><kwd>software package «LIRA-CAD»</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">ГОСТ 9561-91 «Плиты перекрытий железобетонные многопустотные для зданий и сооружений технические условия».</mixed-citation><mixed-citation xml:lang="en">GOST 10180-2012 «Reinforced concrete multi-cavity floor slabs for buildings and structures technical conditions».
