Abstract: Summary To the master’s qualification work Piura S.I, Vashkevich R.V (head). 5-storey residential building with underground parking in Vinnytsia. Lviv Polytechnic National University, Lviv, 2020 Extended annotation The designed building is a residential building with underground parking. The total area of the building is 5188.4 m2. The foundation is monolithic tape, the floor between the floors is monolithic reinforced concrete, the walls are made of 380 mm thick brick, the stairwells and marches are made of reinforced concrete, the roof is multi-sloped with a metal roof structure. In this diploma project a residential building with an underground parking lot was designed, a monolithic reinforced concrete slab of the 1st floor, a monolithic column K-1 of the first floor, a stairwell and a staircase were developed and calculated. In the technological and organizational section, technological maps for the installation of the roof and for the installation of thermal panels of the Fried type have been developed. The diploma project with all corresponding norms, necessary drawings, explanations, calculations and conclusions is developed. Monolithic construction - is the construction directly on the construction site using special forms (formwork structures). This reduces the total cost of the object. The reason is the reduction of logistics costs for the delivery of finished products from the plant and a significant reduction in labor costs. Monolithic structures are 15-20% lighter than prefabricated, and therefore, the amount of material required for the construction of the foundation is reduced and, accordingly, the total cost of the object is reduced. The construction time of such structures differs significantly (to a lesser extent) from the time costs required for the construction of brick buildings. In addition to all of the above, the sound 10 and heat resistance, compared to other construction technologies, increase several times. The master plan of a residential building is developed in accordance with the design task and in accordance with the requirements [1] and [4]. A residential building with underground parking is designed on the construction site. Asphalt-concrete pavement is provided for the designed streets, driveways, platforms for cars and trucks, the carriageway is equipped with curbs along its entire length. Hard paving on sidewalks, footpaths, areas of the pedestrian zone must be made of decorative concrete paving slabs. Spatial planning solutions for a residential building with underground parking have been developed taking into account the requirements [1] and [6]. The building is designed five-storey with underground parking, dimensions in plan 59.22x18.0 m floor height - 2.70 m The connection between the floors is by means of a stairwell, which is located between the axes "5-6". According to these conditions, the geometric dimensions of the residential building, its orientation in relation to the sides of the world, appearance, color of the facade and the tone of shades, and other spatial planning decisions are accepted. When making spatial planning decisions for the design of a residential building with underground parking, the unification of design solutions and structures taken as load-bearing and enclosing was also taken into account. Finishing materials and works are also unified. The center defines symmetry, the right and left parts of the facade are mirror-symmetrical with respect to this center. The building is rectangular in plan (59.22x 18.0m). Step of columns along digital axes - 3,29 m; - step along the letter axes - 6.0 m (section of columns in terms of 0.4 x 0.4 m). The building consists of an underground parking lot and 5 above-ground floors. 11 The planning scheme of the house - frame-monolithic with filling of walls with a brick. The foundation of the building is tape, monolithic (concrete class C16 / 20) according to [2]. External enclosing structures - brick walls. Seismicity of the site - 7 points, soil category by seismic properties - III, according to [5]. The frame of the building is reinforced concrete monolithic according to [3]. Load-bearing structures - floor slabs (flat and without beams), walls, columns. Stairs and internal stairwells - prefabricated reinforced concrete. Internal partitions in a residential building with underground parking are made with a thickness of 120 mm of ceramic solid brick of strength class M125 on the solution of strength class M50, as well as plasterboard arranged on a metal frame. Monolithic reinforced concrete bridges over the openings of a residential building with underground parking are made of concrete class C16 / 20, reinforced at the top and bottom with working reinforcement of strength class A400C for [20] and structural reinforcement of strength class A240C for [20]. The cross section of reinforced concrete monolithic jumpers is rectangular in shape with dimensions: width - 380 mm, height - 220 mm. Prefabricated reinforced concrete bridges over the slots are accepted bar on [21]. Monolithic reinforced concrete slabs of a 5-storey residential building with underground parking are made with support on brick walls, made of concrete class C25 / 30. The cross section of reinforced concrete monolithic slabs supported along the contour is accepted to be continuous over the entire plane and in all directions with a thickness of 180 mm. Reinforcement of reinforced concrete monolithic floor slabs supported along the contour is performed at the top and bottom by working reinforcement of strength class A400C for [20] with a step of 150 mm in both directions, structural reinforcement of strength class A240C for [20].
