Abstract: Hera S.V., Krochak O.V. (supervisor). Sanatorium "Verkhovyna" in Irshava. Master’s thesis. - National University "Lviv Polytechnic", Lviv, 2022 Extended abctract. The project of the sanatorium "Verkhovyna" consists of architectural, structural and scientific sections, as well as a project of works and an estimate. In the architectural part, the requirements for the project, the characteristics of the construction site and the construction area are given [3,6]. The structural scheme adopted is with load-bearing longitudinal and transverse walls. The ceilings are made in the form of monolithic slabs with a thickness of 18 cm. The load-bearing walls are made of brick. The foundations for the walls are designed as ribbons on prefabricated foundation cushions with a width of 0.8 m. The light engineering calculation of the first floor premises has been carried out. In the structural section, the static calculation of the metal roof truss, monolithic floor slab and strip foundation was performed in accordance with current design standards [1,5]. Static calculations of the truss and monolithic slab were performed using the LIRA software complex. [8] 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 concreting of the floor slab has been developed, with instructions for performing the work, a list of necessary materials and mechanisms, and slinging schemes for lifting loads. 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 dedicated to the review and comparison of different types of ceilings that can compete with the monolithic option. To date, many options for prefabricated monolithic ceilings are being developed, which allow to reduce the construction period and labor intensity, to increase the possible loads on the ceiling or necessary spans. Various types of prefabricated monolithic caisson floors were considered in the work. Prefabricated monolithic caisson floors are made of two types of prefabricated reinforced concrete elements: reinforced concrete beams of rectangular cross-section with conventional or pre-stressed reinforcement and ribbed plates of rectangular or triangular shapes. A beamless and cantilevered frame in which the ceiling consists of 3 types of slabs - above-column, between-column and middle. The slabs are unified and manufactured in factory conditions in the same type of formwork, which contributes to ensuring their high quality and increasing production volumes. The size of the plates is 3000 x 3000 mm. The frame of the ARKOS system consists of vertical reinforced concrete columns and rigidly (or hinged) flat disks of interfloor and attic floors and coverings connected to them. The overlapping disks include prefabricated multi-hollow slabs with cavities open to a fixed depth of 100±20 mm on both ends. The object of research is the stress-deformed state of structures and the spatial stability of the building. The subject of research is a 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, slab, foundation, truss, prefabricated monolithic floor. List of used literature sources. 1. DBN B.2.6-98: 2009.
