As a rule, these structures are made of structural and heat-insulating foam concrete, which has good insulation and technical characteristics and sufficient strength. The object of the study is lightweight steel-concrete slab panels, which are one of the special cases of LSCS, made of monolithic foam concrete with density of 400 kg/m3. An analysis of the bending stiffness of LSBC slab panels by comparing the experimental data with analytical calculations was carried out. It was found that bendable LSCS made of monolithic foam concrete with density of 400 kg/m3 operate in physical nonlinear way. It was shown that the bending stiffness of LSCS floor panels can be determined as the sum of stiffnesses of profiled steel and foam concrete at the linear stage of work. The reliability of the proposed methodology within the limits of linear operation was demonstrated. It was proved both experimentally and theoretically that the bending stiffness of panels based on LSCS is higher than the bending stiffness of similar panels made of lightweight thin-walled steel (LTSS) by about 30%.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Легкие сталебетонные конструкции (ЛСБК) относятся к сталебетонным конструкциям, в которых в качестве заполняющего бетона выступает монолитный (заливочный) пенобетон марки D100-D1000, в качестве профильной стали - легкие стальные тонкостенные конструкции (ЛСТК), а функцию несъемной опалубки выполняют фиброцементные панели. Как правило, в данных конструкциях используется конструкционно-теплоизоляционный пенобетон, обладающий хорошими теплотехническими характеристиками и достаточной прочностью. Исследованы легкие сталебетонные панели перекрытия, являющиеся одним из частных случаев ЛСБК, выполненные из монолитного пенобетона марки по плотности D400. Проведен анализ изгибной жесткости панелей перекрытий из ЛСБК на основе сопоставления экспериментальных данных с аналитическим расчетом. Установлено, что изгибаемые ЛСБК из монолитного пенобетона марки по плотности D400 работают физически нелинейно; на линейном участке работы показана допустимость определения изгибной жесткости панелей перекрытий из ЛСБК как суммы жесткостей профильной стали и пенобетона. Продемонстрирована достоверность предложенной методики в пределах линейной работы. Экспериментально и теоретически доказано, что изгибная жесткость панелей на основе ЛСБК больше изгибной жесткости аналогичных панелей из ЛСТК на величину около 30 %.</p></trans-abstract><kwd-group xml:lang="en"><kwd>lightweight steel concrete structures</kwd><kwd>slab panels</kwd><kwd>profiled steel</kwd><kwd>flexural stiffness</kwd><kwd>foam concrete</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>легкие сталебетонные конструкции</kwd><kwd>панели перекрытий</kwd><kwd>профильная сталь</kwd><kwd>изгибная жесткость</kwd><kwd>пенобетон</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was funded by the Russian Science Foundation Grant No. 23-29-00564, https://rscf.ru/project/23-29-00564.</funding-statement><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 23-29-00564, https://rscf.ru/project/23-29-00564.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Tsvetkova A.A.
