Structural and space-planning solutions.

The projected I stage of construction of a multifunctional complex of a normal level of responsibility consists of residential buildings No. 1, No. 2, with an underground built-in and attached parking of residential buildings No. 3, No. 4. Residential building No. 1 - 9-11 storey and residential building No. 2 - 10, The 15th and 22nd floors are designed from 10 sections each, separated by settlement expansion joints. The underground car park is one-story, divided by sedimentary expansion joints into four blocks. Residential building No. 3 - 17 storey and residential building No. 4 - 9 storey, separate. Calculation of buildings of residential houses and parking lot is made on LIRA software systems. Version 9.6, Monomakh. Version 4.5, SCAD. Version 11.3. Residential buildings No. 1, No. 2, No. 3, No. 4. The structural scheme of residential buildings is a wall system with load-bearing longitudinal and transverse monolithic reinforced concrete walls. Spatial rigidity and stability of buildings is ensured by the joint work of vertical load-bearing elements of buildings with monolithic interfloor ceilings. External walls - non-bearing, floor-by-floor cut, based on floor slabs and consisting of aerated concrete blocks of the AEROK type D 400, B 2,5, F 50, 375 mm thick and face hollow brick 120 mm thick, density 1200 kg / m³, M 150, F 50 on a solution of M 100. Non-load-bearing walls are attached to load-bearing structures. The outer walls of the basement are monolithic reinforced concrete with a thickness of 200 mm, 240 mm with insulation from "foam plex" boards with a thickness of 50 - 100 mm. Internal walls - monolithic reinforced concrete with a thickness of 160, 200 mm. Partitions - from blocks SKU 2 R-19 "Melikonpolar" with a thickness of 80 mm. Ceilings and roofing - monolithic reinforced concrete beamless slab with a thickness of 160, 200 mm. Stairs - prefabricated reinforced concrete marches on monolithic platforms. Separate stairs - monolithic reinforced concrete and from prefabricated steps on steel stringers. External stairs and ramps are monolithic reinforced concrete. Elevator shaft walls - monolithic reinforced concrete with a thickness of 160 mm for buildings with a height of 28 m and a thickness of 200 mm for buildings with a height of over 28 m. The material of monolithic structures above 30 is concrete of class B 8 reinforcement of class A I, Bp I, A 150. Underground parking. The designed parking lot is separated from residential buildings by sedimentary expansion joints. The constructive scheme of the parking lot is a frame-wall system of monolithic reinforced concrete structures. The spatial rigidity and stability of the car park is ensured by the joint work of vertical bearing elements with a monolithic coating, the rigidity of the supporting nodes of the columns and stiffening diaphragms. External walls - load-bearing monolithic reinforced concrete 500 mm thick with foam insulation 0.000-25 mm thick. Internal walls - monolithic reinforced concrete 500 mm thick. The columns are monolithic reinforced concrete. The main pitch of the columns is 4,7 x 7,9 m, the section of the columns is 400 x 600 mm. The covering is a monolithic reinforced concrete slab 300 mm thick with capitals 600 mm thick (plan dimensions 1000 x 1200 mm) and contour beams with a section of 400 x 600 (h) mm. Stairs and ramps are monolithic reinforced concrete. The material of monolithic structures is concrete of class B 25, W8, F 100, reinforcement of class A I, A III. The foundations of residential buildings and parking lots are designed based on the results of engineering and geological surveys carried out at the construction site. The construction of the foundations of residential buildings No. 1, No. 2, No. 3 - monolithic reinforced concrete slab grillages 600 mm thick on piles. Piles - bored monolithic reinforced concrete with a diameter of 520 mm, a length of 21,6 m and a length of 28 m (22-storey sections of house No. 2), carried out from the ground using the Fundex technology with a lost tip. At the base of piles with a length of 21,6 m - silty sandy loam with gravel, pebbles, boulders, solid with characteristics e = 0,329, Ι L = - 0,42, E = 200 kg / cm ². At the base of the piles 28 m long there are silty hard clays with the characteristics e = 0,490, Ι L= - 0,57, E = 330 kg/cm². According to the results of static probing of soils and calculation, the design load on a pile 21,6 m long was taken to be 100 tf, on a pile 28 m long - 270 tf. Before the mass execution of piles, the design load on the piles is checked based on the results of pre-design tests of piles with static loads; control tests of piles are provided in the process of pile fields.
