“…Спектр их применения необычайно широк и включает в себя объемно-планировочные решения как небольших зданий сельскохозяйственных предприятий и малого бизнеса, так и каркасов большепролетных зданиях спортивного или общественного назначения [1][2][3][4][5][6]. 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].…”

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.

“…It includes small buildings of agricultural enterprises, small business and large-span buildings for sports or public purposes [1][2][3][4][5]. 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].…”

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.

Introduction. Currently, the purification of wastewater and technological solutions by membrane methods is considered a promising way to neutralize liquid waste. Therefore, the task of developing an engineering method for calculating baromembrane devices is a challenge. Studies on methods involving calculation of design and process variables, membrane equipment design, research of technological features of membrane devices, selection of design schemes, as well as methods of strength and rigidity analysis, are investigated.Materials and Methods. Basic elements of the body of the combined membrane apparatus are considered, a design scheme is proposed, and a method for calculating the strength and rigidity of the main load-bearing element, the cover, is described. Results. The methods determine the required dimensions of shells and plates for the development of a combined membrane apparatus, and evaluate the strength properties of the devices of this class. The construction elements of the apparatus (primarily, the load-bearing covers) must meet not only the requirements of efficiency and quality of separation and cleaning of solutions, but also the conditions for safe operation. Therefore, the design of the device covers should be based on the optimal design dimensions (thicknesses of round plates, toroidal shells, and support rings). To test the method, the stress-strain state of the membrane apparatus structure was calculated for strength and rigidity. As an example, we consider one cover presented in the form of an open toroidal shell. The evaluation of the application of this technique, taking into account the fact that the shell is mated with a round plate in the inner diameter, and with a ring in the outer diameter, has provided the determination of the required parameters.Discussion and Conclusions. The obtained method of analytical description of the mechanical impact on the elements of the combined apparatus and the example of calculating the toroidal shell and plate, enables to evaluate the stressstrain state of the structure for strength and rigidity. The results of the calculation of covers made of various materials at different pressures are presented. Loading the combined apparatus with transmembrane pressure made it possible to determine the required dimensions of the shells and plates for its design and development.
