The peculiarities of each type behavior were revealed, that is of interest for their prospective reduction to practice of structural design.</p></abstract><trans-abstract xml:lang="ru"><p>Цели. В статье произведен анализ и сравнение результатов статического расчета оболочек на действие распределенной нагрузки типа собственного веса. Исследованы оболочки переноса с одинаковыми габаритными размерами четырех видов: поверхности переноса цепной линии по цепной, окружности по окружности, эллипса по эллипсу и синусоиды по синусоиде. Методы. Для расчетов применялся метод конечных элементов. Исследование проводилось для оболочек из материала с характеристиками условного железобетона. Результаты. Сравнительный анализ результатов показал, что наиболее выгодное для строительных конструкций поведение под нагрузкой демонстрируют оболочки в форме поверхности переноса цепной линии по цепной и окружности по окружности. Наихудшими для железобетонного строительства являются оболочки в форме поверхности переноса эллипса по эллипсу. Выявлены особенности напряженно-деформированного состояния перечисленных объектов, представляющие интерес для потенциального внедрения таковых в практику проектирования и строительства.</p></trans-abstract><kwd-group xml:lang="en"><kwd>translational surface</kwd><kwd>thin elastic shell</kwd><kwd>finite element method</kwd><kwd>static analysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>поверхности прямого переноса</kwd><kwd>тонкие упругие оболочки</kwd><kwd>метод конечных элементов</kwd><kwd>статический расчет</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Novozhilov V.V., Chernyh K.F., Mihajlovskij E.I.
