Structural and space-planning solutions

The car park building is designed in a bonded prefabricated reinforced concrete frame series 1.022 KL2. The spacing of the columns is irregular from 3,0 m to 8,4 m. Columns - section 400x400 mm. Crossbars - two-shelf 450 mm and 600 mm high, depending on the span of the frame. Floor slabs with a thickness of 220 mm: hollow-core flooring and solid strut slabs. The stability and spatial rigidity of the building is ensured by the spatial work of vertical, horizontal stiffening diaphragms and structural elements of the frame. Prefabricated reinforced concrete vertical stiffening diaphragms with a thickness of 140 mm are the walls of the stairwells and form the stiffening cores. Floor slabs are horizontal stiffening diaphragms: spacer slabs have welded joints with crossbars, hollow core slabs are installed between the spacer slabs, hinged on the crossbars. Material of overhead structures: columns - concrete class B40, F100 (lower tier); B2.25, F100 (upper tier); stiffness diaphragms - class B25 concrete; F100; floor slabs - class B40 concrete; F100. Fittings for all structures of class A400; A500C, rope reinforcement as prestressing reinforcement for floor slabs. Static and dynamic calculation of the building's load-bearing structures was performed by Barrikada Production Association OJSC using the Lira 9.6 software package. The level of responsibility of the building is normal. The foundations of the building are monolithic reinforced concrete free-standing grillages for columns 1500 mm high on a pile foundation. Reinforced concrete driven piles with a section of 35x35 cm, length 23,0 m. At the base of the piles at absolute elevations of minus 15.90 and 15.20 there are hard clays with a total deformation modulus of 240 kg/cm2. The design load on the pile - 110 tf, was adopted based on the results of static sounding of soils and by an analytical method using the main regulatory documents. Static load testing of piles and, if necessary, adjustment of the pile field are provided. Material of underground structures - concrete class B20, B22,5, B25 (piles); F100, W8, fittings class A500C. In places where the level difference is 1,5 m between the ground floor and the layout, angle-type retaining walls made of monolithic reinforced concrete are designed, which are not connected with the grillages of the building. The apartment building consists of 4 sections. Two sections are interlocked into a separate block, all other sections are separated by expansion joints. The building was designedThe building was designed in a cross-wall system of prefabricated reinforced concrete products produced by ZAO DSK Blok. The basement structures of all sections are monolithic reinforced concrete walls and a 200 mm thick ceiling. Internal walls - reinforced concrete panels 200 mm thick (1-8 floors); 160 mm. Interfloor floors - prefabricated reinforced concrete flooring 160 mm thick. External walls: single-layer reinforced concrete panels with a facade insulation system - load-bearing end panels 160 mm thick; non-bearing hinged - panels 120 mm thick; three-layer end walls with a thickness of 420 mm with flexible connections, the thickness of the bearing layer of reinforced concrete is 160 mm. Panels are installed in places of expansion joints. The joints of the outer walls are closed, sealed with mastic over sealing gaskets. Conjugation of load-bearing wall panels and floor slabs in the form of a platform joint. The vertical joints of the load-bearing panels are provided with keyed connections and steel mounting connections with the joints sealed with fine-grained concrete. The spatial rigidity of the building is ensured by the joint work of the transverse and longitudinal walls, combined into a single spatial system by disks of interfloor ceilings. The static calculation of the load-bearing structures of the building was performed using the Lira 9.6 software package. The level of responsibility of the building is normal. Horizontal movement of the top of the building - 8,8 cm; acceleration of oscillations of section structures, arising from the pulsation of the velocity pressure of the wind 0,044 m/sec2, which does not exceed the maximum allowable values. The maximum values ​​of mutual shifts between walls and ceilings in the platform joint are 0,7 mm. The maximum values ​​of mutual shifts between the walls of the perpendicular direction are 0,1 mm, which does not exceed the maximum allowable values. The foundations of the sections are monolithic reinforced concrete strip grillages 600 mm high on a pile foundation. The grillages are united by a plate 250 mm thick. Piles - reinforced concrete driven with a section of 40x40 cm, 23 m long; 24 m, composite along the length, the joint of the piles is welded. The connection of piles with grillage is rigid. Material of underground structures - concrete class B25; W10; F100. At the base of the piles at elevations from minus 21.30; 22.30:240 p.m., silty hard clays occur with a total deformation modulus E = 2 kgf / cm120. The design load on the pile is 0,000 tf, based on the results of static sounding of soils. Static load tests of piles are provided. Waterproofing of basements from groundwater: the use of high-grade concrete for water resistance for the foundation slab and external walls, the use of waterstops in expansion joints and in working joints of concreting. During the construction period and in the initial period of operation until the stabilization of the sediment, it is planned to conduct observations of the precipitation of a multi-apartment residential building under construction.
