Abstract: Annotation Sosula OM , Titarenko R.Yu. (head). A complex of stands with the basement of the stadium in Berezhany. Master’s qualification work. Lviv Polytechnic National University, Lviv, 2020. Initial data for design The projected building is part of a complex of buildings on the street. Ivana Franka 15, Berezhany. The construction site of the complex is located in a group of other existing buildings and structures. It is also planned to dismantle existing buildings and build new ones in their place. This complex is designed for construction in 1 climatic region, seismicity of the construction site - 6 points. Spatial planning solution The construction site of the tribune complex is rectangular in plan and occupies 3.08 hectares. The building has a complex sectional shape with the overall dimensions of the sections in the axes: section A 100.8x20.25 m; section B 62.1x20.25 m; section B 62.1x20.25 m; section G 60,3х20,25 m; Constructive solution The basement rooms consist of three floors, the 1st and 2nd closed type, and the 3rd open type. According to the structural scheme, the building is designed with longitudinal and transverse load-bearing walls. In the building, the longitudinal and transverse walls, stairwells and horizontal stiffening diaphragms, which are formed by monolithic reinforced concrete floors, are responsible for the spatial rigidity. Monolithic reinforced concrete stairs with marches 2.8 and 1.4 m wide and 2.0 m wide platforms are planned for the building. Constructive section To calculate the subunit complex, I collected the load on the structure in accordance with DBN B.1.2-2: 2006 "Loads and impacts". The calculation section begins with the selection of reinforcement in the floor slab. The next step is to calculate the frame and introduce additional support. The final stage is the calculation of the folds of the stands with a span of 8.4 m. To calculate the frame and load-bearing structures under the grandstand, I used the software and calculation complex "Lyre". According to the task, the constructive scheme of a frame in the given program was composed. Calculation of the floor slab The calculation of the plate is carried out in the software complex "Lyra" and in the subroutine "Lyr-workstation". After calculating the slab, I designed a monolithic slab of heavy concrete class C25 / 30 and 40 cm thick. I accepted the upper reinforcement of reinforcement A-400C ?12 mm, with a step of 200 mm, in the places of supports. Additional reinforcement is performed in places where there are maximum moments, from the reinforcement A-400C ?20 mm, with a step of 200 mm, in two directions. Calculation of the frame The calculation of the frame is performed in the software package LIRACAD. In the calculation process, an additional intermediate resistance was introduced as the deformation of the frame exceeded the allowable norms. The main frame is made of fittings?16, A400 , auxiliary fittings?10, A400;?20, A400 Calculation of the folds of the stands with a span of 8.4 m The calculation of folds is carried out in the software package Lyra CAD. The following geometrical characteristics are accepted: Plate horizontal: plate thickness H = 15 cm; The wall is vertical: a plate with a thickness of H = 18 cm Wall reinforcement: Top fittings 2?16, A400 Lower fittings 2?25, A400 Transverse reinforcement 1?10, A400(крок_100 / 200) Slab reinforcement: Top fittings 4?10, A400 Lower fittings 4?12, A400 Transverse reinforcement 2?10, A400(крок_ 200 / 400) Construction production technology The technological map is designed for the process of erecting a monolithic reinforced concrete floor over the third floor. The map includes such processes as reinforcement, arrangement of formwork, laying of concrete mix, care of it and dismantling of formwork. Floor height 3.0 m with a floor thickness of 400 mm. The process is carried out by a set of machines according to the main scheme "crane-bucket": tower crane KB-405, delivery of concrete mix is carried out by concrete trucks Ford Cargo ABS-9 DA Tigarbo on distance of 25 km. Works are carried out by complex crews in two shifts. Instructions for work: At the preparatory stage of work it is necessary to control: - correct selection of the composition of the concrete mixture, in accordance with the project instructions; - quality of application of materials for preparation of concrete mix; - readiness of the concrete-mixing, transport and auxiliary equipment for production of concrete works; In the process of laying the concrete mixture it is necessary to control: - condition of formwork and scaffolding, design position of reinforcement products and frames; - quality of laying of mortar; - observance of rules of giving, unloading and distribution of concrete mix on the area; - the thickness of the layer to be laid; - mode and type of concrete mixture compaction; The results of concrete quality control should be reflected in the log and acts of hidden and accepted works. Construction economics In this section, I have compiled a local estimate for the main construction and installation work. All calculations were made on the basis of prices and time norms for major construction works as of November 2020. I calculated the total cost of building a sub-complex. The estimated cost of construction is 28408829 UAH. Research section The aim of the research is to get acquainted with the constructions of these types in the world and directly in Ukraine.
