Structural and space-planning solutions

Building responsibility level – II (normal). The project provides for the construction of a residential building made of monolithic reinforced concrete, consisting of ten sections and an attached parking lot. In the building between the sections, expansion joints are provided. The parking lot is separated from the residential building by a sedimentary seam. Structural system of sections - wall with load-bearing transverse and longitudinal walls. The step of monolithic reinforced concrete walls is from 3,4 m to 6,8 m. The load-bearing monolithic reinforced concrete walls of the basement and 1 ÷ 4 floors are assumed to be 200 mm thick, the walls of 5 ÷ 15 floors are 180 mm thick. Ceilings and roofing - monolithic flat reinforced concrete slabs, 180 mm thick. Bearing external walls (staircases and end walls) are multi-layered from monolithic reinforced concrete, effective insulation and plaster. Enclosing external walls - non-bearing, with floor-by-floor support on ceilings, multilayer - made of ceramic hollow brick M125, F35 250 mm thick, on mortar M75, effective insulation and thin-layer plaster on the grid. Heat-insulating plates are attached to the walls with glue and expansion dowels. Fastening of the outer walls to the supporting structures of the building is provided by flexible stainless steel ties. The walls of the elevator shafts are prefabricated reinforced concrete from three-dimensional blocks. Flights of stairs - prefabricated reinforced concrete, intermediate platforms - monolithic reinforced concrete, reinforced with individual rods. Ventilation blocks - prefabricated reinforced concrete. Construction material: for external walls and floor slabs of the underground part - concrete of class B 25, W12, F50; for walls and floor slabs - concrete class B 25; for external sections of ceilings and coatings - concrete of class B 25, F75; fittings of class A 400, A240. The spatial rigidity and stability of the building is ensured by the joint work of the transverse and longitudinal internal walls, united by horizontal disks of floors and roofs. The load-bearing structures were calculated using the SCAD 11.3 software package, taking into account the joint work of the building with the foundation. Horizontal movement of the top of the building 5,84 cm; acceleration of vibrations of building structures 0,058 m/s2. The main load-bearing structures of the building are designed to meet fire resistance requirements in accordance with STO 36554501-006-2006. The foundations of the residential building are piled. Piles - driven prefabricated reinforced concrete, section 40 x 40 cm, length 19 m (for the 3-storey part of the building - 13 m), from concrete of class B 25, W8, F75, immersed by driving into leader wells. In accordance with the report on engineering and geological surveys, 2011, the lower ends of the piles are immersed in soils: EGE-9, semi-solid loams with gravel and pebbles (E=230 kgf/cm2, IL=0,14, e=0,465) and EGE -10, silty dense sands (E=350 kgf/cm2, φ=32º, e=0,500). The expected average draft of the sections is 4,5 cm. The calculated pile load of 120 tf (for the 3-storey part of the building 80 tf) was adopted based on the results of static sounding. The allowable design load on the pile will be verified by static pile testing prior to mass pile driving. Grillage grillages - tape made of monolithic reinforced concrete of class B25, W8, F50, 900 mm high, united by a monolithic reinforced concrete basement floor slab 200 mm thick. Pairing of piles and grillage is rigid. Under the grillage, concrete preparation is provided from concrete of class B 10 with a thickness of 100 mm. The relative mark of 0,000 corresponds to the absolute mark of 7,900. The car park is designed from monolithic reinforced concrete class B25, with an exploitable roof. The constructive system of the parking lot is column-wall with load-bearing walls and columns. The pitch of the columns is 8,0 × 7,5 m and 8,0 × 5,5 m. The car park building is divided into two blocks by an expansion joint. Columns are taken with a section of 500 x 600 and 500 x 500 mm, external walls - 300 mm thick. The parking lot cover is a monolithic reinforced concrete beamless slab 300 mm thick, with thickenings in the capital part. Capitals measuring 3,0 x 3.0 m and 3.0 x 2 m, 0 mm high. Car parking structure material: for the outer walls and floor slab of the underground part - concrete with compensated shrinkage of class B250, W25, F12; for columns - class B50 concrete; for the roof slab - concrete with compensated shrinkage of class B25, W25, F12; fittings of class A 50, A400. The spatial rigidity and stability of the car park is ensured by the hard disk of the pavement, the rigid junctions of the columns with the pavement, and the pinching of the columns into the foundations. The calculation of the car park structures together with the base was carried out using the SCAD 240 software package. The parking lot foundations are piled. Piles - driven prefabricated reinforced concrete, section 40 x 40 cm, length 12 m, from concrete class B 25, W8, F75. The lower ends of the piles are immersed in the EGE-8 soil, plastic sandy loam with gravel and pebbles (E=230 kgf/cm2, IL=0,14, e=0,462). The design load on the pile is 80 tf, based on the results of static sounding. Expected draft 1,2 cm. The allowable design load on the pile will be verified by static pile testing prior to mass pile driving. Grillage grillages - cluster made of monolithic reinforced concrete of class B25, W8, F50, 900 mm high, united by a monolithic reinforced concrete basement floor slab 300 mm thick. Pairing of piles and grillage is rigid.
