“…The absence of tie-beams between arches always leads to overspending of materials for the construction of building foundations. For some light arched buildings, for example, frameless ones [21,22], made of profiled sheeting, combining both enclosing and bearing functions, the use of tie-beams is one of the prerequisites for the possibility of their use with sufficiently large spans in areas with significant snow load. Scientists of Kazan state university of architecture and engineering (KSUAE) proposed structural solutions (see Figs.…”

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.

Recently, in the practice of design, customers of design works and investors of various projects have a dilemma regarding the choice of building material for load-bearing building structures. At the same time, the choice is usually limited to two types of materials – steel and reinforced concrete. Each of these materials has its advantages and disadvantages, which results in their different efficiency of application for various types of building structures. At the same time, the main attention is paid to the estimation side, because in modern complex and dynamic conditions, it turns out to be dominant in many cases. The article presents the results of research of the completed master's thesis on the comparative analysis of the effectiveness of steel and combined frames (steel-reinforced concrete) on the example of the filter station building. The building has dimensions in plan of 54 × 36 m with a total height of about 22 m. Its supporting frame is a statically nondefined flat frame consisting of columns and crossbars in the form of trusses. In the longitudinal direction of the building, the frames are united into a spatial system by means of covering structures. The building is craneless and has three floors, each about 6.5 m high. In the course of research, the considered variants of the transverse frame were analyzed using the finite element method on the basis of the LIRA-CAD multifunctional design complex. As a result, appropriate cross-sections for loads according to the climatic conditions of Ukraine were obtained. A comparison of variants showed that the first design variant is 9 % cheaper. Taking into account the additional technological advantages in its manufacture, the steel frame can be considered more effective for the given construction conditions and be recommended for practical implementation. Separately, it should be noted that such a frame also has an average of 5 times less total mass, which should be considered its additional advantage.

Purpose. The work is aimed to study the use efficiency of fine-grained heat-strengthened steels (mainly 10G2FB) for steel bunker capacities. At the same time, the structural scheme of such a structure using corrugated steel sheets is considered as the main variant. Methodology. To achieve this purpose, a series of numerical calculations was carried out for a steel bunker capacity of a pyramidal-prismatic type with overall dimensions in plan view of 6×5.2 m and a total height of 4.5 m. The capacity was designed for complicated working conditions, in particular, increased loads, including long-term dynamic ones. The potential possibility of operating the container under conditions of high or low temperatures was also taken into account. At the same time, both the traditional structural scheme of a bunker capacity with horizontal stiffening ribs and the developed structural scheme based on corrugated steel sheets were analyzed. The calculations were carried out by the finite element method based on the SCAD for Windows project complex. Findings. Based on the results of the analysis and comparison of the data obtained in numerical calculations, it was found that the use of fine-grained heat-strengthened high-strength steels (for example, steel 10G2FB) for bunker capacities, both the traditional structural scheme with stiffening ribs and the developed structural scheme based on corrugated sheets, allows reducing material consumption by about 30% in both cases. At the same time, due to the good performance of fine-grained heat-strengthened steel 10G2FB, both at high and at low temperatures, it can be effectively used for steel bunker capacities that work in difficult conditions. Originality. The possibility and efficiency of the use of fine-grained, heat-strengthened high-strength steels for the construction of a steel bunker capacity is estimated. At the same time, such an estimation was given not only for structures of the traditional structural scheme with horizontal stiffening ribs, but also for bunkers with a developed structural scheme based on corrugated sheets. Practical value. From a practical point of view, quantitative parameters of the stress-strain state were obtained during investigations of various design variants for a steel bunker capacity. The data are presented in a compact form that is easy to evaluate and compare. They allow us to state about the improvement of the operation characteristics of capacities and the potential reduction of the risks of their failures and accidents during operation.
