Abstract: The project of the factory building consists of architectural, constructive and scientific sections, as well as the project of works and estimates. In the architectural part, the requirements for the project, the characteristics of the construction site and the construction area are given [3,6]. The adopted constructive scheme is a frame. The frame consists of reinforced concrete columns placed with a step of 6 m along the external axes and a step of 12 inside the workshop. Metal trusses on which roofing sandwich panels are laid serve as a covering. The external walls are designed from aerated concrete blocks and the internal from ceramic bricks. The foundations for the walls are designed as strip foundations on prefabricated foundations, and columnar foundations for the columns. The heat engineering calculation of the outer wall has been performed. In the structural section, the static calculation of the metal covering truss, metal perforated covering beam, reinforced concrete column and columnar foundation was performed in accordance with current design standards [1,6]. Static calculations of the truss and perforated beam were performed using the LIRA software complex. [10] In the work execution project, a general plan of the construction site was developed with the introduction of temporary communications, placement of wagons for workers and administration, warehouses with construction materials. Determined dangerous areas of operation of cranes, measures to ensure safe operation [2]. A technological map for the installation of roof trusses has been developed, which includes instructions for performing the work, a list of necessary materials and mechanisms, and slinging schemes for lifting the trusses. To determine the cost of construction, the scope of work and the necessary materials are determined, on the basis of which an estimate is made. The scientific section is devoted to the study of reinforced concrete structures make it possible to reduce material consumption, increase the load-bearing capacity of structures due to the rational combination of sheet steel and reinforced concrete. In steel-concrete cross-sections, reinforcement is placed on the outer faces, which makes it possible to increase the working height of the cross-section and obtain a corresponding increase in strength and rigidity or to reduce the dimensions of the cross-section of the structure, as well as to use external sheet steel as a formwork during concreting, and after the concrete has hardened - as a load-bearing reinforcement . The work investigated the stress-deformed state of a fragment of the floor, which consisted of a steel concrete beam and a fragment of a steel concrete floor slab connected to each other by anchors using electric arc welding. A full-scale test of the fragment was performed, and the obtained results were used to evaluate the bearing capacity of reinforced concrete structures [7,8,9]. The conducted study of a fragment of a floor with a steel-concrete beam showed that the use of strip reinforcement in the compressed zone of the beam significantly increases its rigidity, and as a result, leads to a decrease in its deflections. The width of crack opening in the stretched zone under operating loads did not exceed 0.01-0.02 mm. In terms of material consumption, this construction is economically beneficial, due to the reduction of the amount of concrete and reinforcement, but at the same time it has a higher labor intensity, which in the modern development of the industry may not be a determining factor. The object of research is the stress-deformed state of structures and the spatial stability of the building. The subject of the study is the shop building. The purpose of the study is to determine the strength and stability of both individual structures and the stability of the building as a whole under the action of a set of permanent and temporary loads. Studies have shown that the strength of structures is ensured by the first and second group of limit states. Key words - building, strength, stability, beam, column, foundation, truss, reinforced concrete floor. List of used literature sources. 1. DBN B.2.6-98: 2009.
