That method can be implemented in the conditions of architectural and structural solutions of buildings with the presence of zones which prevent the traditional placement of puffs. There are no research results on this problem in the literature. On the example of a frameless arched building with insufficient bearing capacity of the supports for the perception of the strut, the application of the anticipated reinforcement method is considered with the reduction of two options for anchoring the supports of the arched building with puffs installed for the perception of the strut to semi-buried and sunken ground anchor. For the arched building under consideration, theoretical studies were carried out to determine the prestress value in the installed puffs, at which the load-bearing capacity of the arched building is provided for the variant of the asymmetric snow design load. The significance of the obtained results for the construction industry is that for the first time a method of strengthening arched buildings with insufficient bearing capacity of supports for the perception of the strut is suggested. The projected method of reinforcement is an effective, novel way to increase the load-bearing capacity of structures and supports of arched buildings and can be used in the conditions of architectural and structural solutions of buildings with the presence of zones that prevent the traditional placement of puffs.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Предлагается новый способ усиления арочных зданий с недостаточной несущей способностью опор для восприятия распора. Он может быть реализован в условиях архитектурно-конструктивных решений зданий с наличием зон, препятствующих традиционному размещению затяжек. В литературе отсутствуют результаты исследований по этой проблеме. На примере бескаркасного арочного здания с недостаточной несущей способностью опор для восприятия распора рассмотрено применение предлагаемого метода усиления с приведением двух вариантов анкеровки опор арочного здания затяжками, устанавливаемыми для восприятия распора к полузаглубленным и заглубленным якорям-анкерам. Для изучаемого арочного здания проведены теоретические исследования по определению величины преднапряжения в устанавливаемых затяжках, при которой обеспечивается несущая способность арочного здания для варианта несимметричной снеговой расчетной нагрузки. Значимость полученных результатов для строительной отрасли состоит в том, что впервые представлен способ усиления арочных зданий с недостаточной несущей способностью опор для восприятия распора. Данный способ усиления несущей способности конструкций и опор арочных зданий является эффективным, обладающим новизной и может применяться в условиях архитектурно-конструктивных решений зданий с наличием зон, препятствующих традиционному размещению затяжек.</p></trans-abstract><kwd-group xml:lang="en"><kwd>arched building</kwd><kwd>strut</kwd><kwd>support</kwd><kwd>tightening</kwd><kwd>anchor</kwd><kwd>frameless arched building</kwd><kwd>prestressing</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>арочное здание</kwd><kwd>распор</kwd><kwd>опора</kwd><kwd>затяжка</kwd><kwd>анкер</kwd><kwd>бескаркасное арочное здание</kwd><kwd>преднапряжение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sheidaii M.R., Bayrami S., Babaei M.
