Abstract: The work consists of 11 sheets of the graphic part (of which: four sheets of the architectural and construction section; four of the calculation and construction section; three technological and organizational sections) and an explanatory note. In the master’s qualification work, "Residential building with built-in two-level underground parking on the street was designed. Horodotska, 64, in the city of Lviv » on a plot of land with an area of 0.9014 ha. The building area is 1677.0 m2. The architectural and construction section presents general data on the site on which construction is taking place (plot area, construction area, percentage of construction, area of premises, etc.); basic information on architectural and planning, volumetric and design solutions, landscaping and explanation. The main constructive solutions: • structural scheme of the building - load-bearing monolithic reinforced concrete frame. Transverse rigidity of the building is provided by rigid joints of columns and floors, as well as diaphragms; • the foundations - foundation slab, 600 mm thick. Concrete class C25/30 F150 W6-8; A500C class working fittings and A240C class structural fittings • the basement walls - monolithic reinforced concrete with a thickness of 250, 400 mm. Concrete class C25/30. External internal walls and partitions, to be made of regular hollow ceramic brick KRPv-1/100. • the columns - monolithic reinforced concrete sections of 750x250mm, 1250x250mm, 400x400mm, 400x600mm, 1150x250mm, 400x250mm, 250x250mm. Concrete class C25/30; A500C class working fittings and A240C class structural fittings. • ceiling - monolithic reinforced concrete slabs 200 and 250 mm thick. Concrete class C20/25; A500C class working fittings and A240C class structural fittings • stairs - monolithic reinforced concrete with monolithic platforms. The stair railing is attached to the steps. The stairs are finished with ceramic tiles. • the roof is pitched, rafter made on a reinforced concrete frame in the form of reinforced concrete beams and reinforced concrete columns. In the calculation and design section, the calculation of four load-bearing structures was performed, both with the help of programs (PC LIRA - CAD, Monomakh) and manually. 1. Calculation of the foundation slab was performed using the Lyra-SAPR software complex. The reinforcement calculation was performed automatically. The upper and lower mesh with a cell size of 200 mm from O12 A500C and O10 A500C reinforcement is adopted. 2. I perform the calculation of the column based on the results of the calculation of the building frame in PC LIRA - CAD, based on RSZ. I calculate the reinforcement manually. 3. Calculation of a monolithic floor slab of a typical floor. I perform the calculation in PC LIRA - CAD. The plate is supported along the contour (on columns and walls). An upper and lower mesh with a cell size of 200 mm from O8 A500C reinforcement is adopted. 4. The monolithic beam is calculated automatically using the "Monomach" and "Lyra-CAD" programs. The reinforcement is calculated manually. In the technical and organizational department, a technological map for the execution of the floor slab of a typical floor was presented, and a construction master plan for the execution of works was developed. Also described are measures for occupational health and safety, safety and environmental protection. A calendar schedule of construction works has been drawn up. The duration of construction is 176 days. In the economic section, based on the volumes of work on materials, a local, consolidated and object estimate for construction works was made. The labor intensity and salary information for the facility estimate is also calculated. In the scientific section, the most heavily loaded column -2nd floor was investigated for fire resistance. Methods of fire protection of reinforced concrete structures are considered. According to the calculations, it was recommended to protect the column with fire-resistant plates or sheets of fibrous materials to reduce the effect of fire on the exposed surface of the column, this will reduce destruction when extinguishing the fire with water, since large cracks may form due to the difference in thermal deformation.
