“…These were further investigated by the same approach in Eroglu et al [41] for parabolic arches; it is found that neglecting the coupling due to crack may be misleading in identification problems, especially for shallow arches. The position of the crack on the cross-section is further examined in [42] for static problems, and in [43] for stability problems of parabolic arches.…”

“…Отличительными особенностями арочных зданий являются возможность быстрого возведения, небольшая масса конструкций, низкая стоимость строительства и необходимость учета при проектировании опор арочных зданий воздействия распорных опорных реакций [7][8][9][10][11]. Проблему восприятия распорных усилий и уменьшения расхода материалов на устройство опор в арочных зданиях решают установкой затяжек между опорами арок [12][13][14][15][16][17][18][19]. Установка затяжек в арочных сооружениях влечет сложности в виде необходимости их скрытой установки в конструкции полов здания, обязательности их преднапряжения при больших размерах пролетов для сохранения рабочего состояния, невозможности традиционной установки затяжек между опорами арок при расположении между ними инженерных коммуникаций, технологических объектов здания.…”

A new way to strengthen arched buildings with insufficient bearing capacity of the supports for the perception of the strut is proposed. 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.

“…Distinctive features of arched buildings are the ability of quick erection, a small mass of structures, low construction costs and the need to take into account the impact of thrust support reactions when designing the foundations of arched buildings [6][7][8][9][10]. The problem of perceiving thrust structures and reducing the material consumption for the foundation construction in arched buildings constructors solve by installing tie-beams between the arches' supports [11][12][13][14][15]. Builders face some problems when installing the tie-beams in arched structures: the need for their hidden installation in the construction of the floors; the necessity to prestress them to maintain a working condition at large spans; the impossibility of standard installation of tie-beams between the arch supports when utility lines of technological objects of the building located between the arch supports.…”

This paper proposes a new way to strengthen arched buildings with an insufficient bearing capacity of the foundations for the thrust perception. The new method of strengthening the arched buildings can be used in architectural and structural solutions of buildings with zones where it is impossible to place tie-beams traditionally. In the literature there are no research results on this issue. The authors described a new method of strengthening arched buildings. Using a frameless arched structure with an insufficient bearing capacity of the foundations for the thrust as an example, they considered the proposed strengthening method with two options for anchoring the arched building's foundation with tie-beams installed to perceive the thrust to semi-buried and buried anchors. The authors carried out theoretical studies and determined the magnitude of the prestresses in the installed tie-beams to ensure the bearing capacity of the arched building for the variant of asymmetric snow design load. Conclusions. The significance of the obtained results for the construction industry is to propose a method to strengthen arched structures with an insufficient bearing capacity of the foundations for the thrust perception. The proposed method of strengthening is an effective and novel way of increasing the bearing capacity of structures and foundations of arched buildings and can be used in architectural and structural solutions of buildings with zones that impede the traditional placement of tie-beams.
