Abstract: Akhmedov A.S., Associate Professor Barabash V.M. (supervisor). Construction of a three-section residential building in Chernihiv, 36 Prydesnyanska Street. Master’s thesis - Lviv Polytechnic National University, Lviv, 2023. Extended abstract. This project envisages the design, construction, and calculation of 4 building structures in Chernihiv at 36 Prydesnyanska Street. Land allocation is provided for the construction of this site. The building layout is structural with longitudinal and transverse load-bearing walls. The external walls of the 1st floor are 680 mm thick with an expanded joint internal walls - 380, 250 mm. The internal and external walls have openings for windows and doors, which are covered with reinforced concrete lintels. The brickwork of the exterior walls for the 1st floor is 680 mm thick. The masonry with an expanded seam of foam concrete is 50 mm thick. The exterior walls are made of 150/25 silicate brick (Samibra Silicate Brick Plant) for floors 1-7, and 125/25 brick for floors 8-10. The mortar grade was M 100 for floors 1-7, M 75 for floors 8-9, and M 50 for the 10th floor and attic. The facing layer is made of ceramic thickened hollow face bricks. The internal walls are 380 and 250 mm thick, made of 150/15 solid silicate brick (Sambir Silicate Brick Plant) for floors 1-7 and 125/15 brick for floors 8-10 and the attic. The mortar grade is M 100 for floors 1-7, 75 for floors 8-9, and M 50 for floors 10 and the attic. The facing layer is made of ceramic thickened hollow face bricks. The internal walls are 380 and 250 mm thick, made of 150/15 solid silicate brick (Sambir Silicate Brick Plant) for floors 1-7 and 125/15 brick for floors 8-10 and the attic. The mortar grade is M 100 for floors 1-7, 75 for floors 8-9, and M 50 for floors 10 and the attic. The masonry walls with ventilation ducts are made with continuous filling of the joints with mortar and mopping of the inner surface of the ducts. The interior partitions are made of brick, and the inter-apartment partitions are made of insulation and brick. The floors are made of monolithic reinforced concrete. These are load-bearing and protective structures. In addition, they give the building spatial rigidity, absorbing all the loads imposed on them, and provide heat and sound insulation for all rooms. All slabs create a single hard disk of the floor. Circular recesses are provided in the longitudinal side faces of the slabs to ensure that they work together to resist vertical and horizontal movement. In this thesis project, a foundation slab is provided. The foundations are designed with loam as the base material. The foundations are laid on compacted soil, followed by 100 mm thick sand, 20-40 mm crushed stone, and then concrete preparation of C10/15 grade is poured. The monolithic embedments between the foundation slabs are made of C10/15 concrete with reinforcement d=10 A240 (8 bars per 1 meter). For drainage of surface water around the perimeter of the building, an asphalt blind area 30 mm thick and 1000 mm wide was made on top of a 100 mm thick gravel-sand fill. To protect the foundation and wall structures from groundwater, the project envisages a two-layer waterproofing with hot bitumen mastic on a leveled surface and membrane protection. All utilities that fall under the building must be removed before the foundation work begins. Backfill under the basement floors, backfill of the sinuses, and backfill under the wings is performed with a sand and gravel mixture or medium coarse sand. The transition to mass construction of high-rise buildings will have a significant economic effect and provide the majority of people with apartments at "affordable" prices. Object of construction - Construction of a three-section residential building in Chernihiv, 36 Prydesnyanska Street. The purpose of the construction is to solve the problematic issues of the region. This object consists of three buildings interconnected by a thermal joint: block section A and block section B, which have a rectangular shape in plan with dimensions along the axes of 15150x27500 mm, 15150x23100, and 15150x27500. The building consists of three sections with 10 residential floors, an unheated basement and a warm attic. The height of the residential floor is 2.7 m, the height of the basement is 1.93 m, and the technical floor is 1.8 m. The relief of the plot is calm. The relief organization project provides for natural water drainage from the territory of the projected building. Asphalt pavement for driveways, parking lots, and tile pavement for sidewalks are used in the landscaping elements. Gravity drainage is provided along the perimeter of the building with water discharge into the city storm sewer. The area under construction covers almost 1500m2, including landscaping and parking areas. The building under construction covers an area of 800 m2 and has a northwest orientation of the main facade. The commercial premises available in the building are located in the northeastern part of the building, which corresponds to the meridional orientation, providing the longest insolation of the building of the second climate zone. The graphic part of the master’s thesis is represented by ten sheets, which include architectural solutions, solutions for the technology and organization of construction production, as well as drawings of structures that were calculated in the structural section. Key words - architectural solutions, monolithic construction, 3-section, project, floors, reinforced concrete frame, graphic part, section.
