Structural and space-planning solutions

 The projected 20-storey residential building - a normal level of responsibility, consists of two separate buildings (building 6.1 and building 6.2). Building 6.1 is designed from 5 sections separated by expansion joints. Building 6.2 is designed from 4 sections separated by a sedimentary expansion joint. The designed stand-alone one-story underground car park of a normal level of responsibility is divided into two blocks by a sedimentary expansion joint. The calculation of the building of a residential building and a parking lot was performed using the software systems Lira SAPR-2012, LIRA. Version 9.6, LIRA. Version 9.4. SCAD.
Version 11.3.

The outer layer in the basement panels is made of concrete class B 25, W 6, F150, the middle layer is made of PSB-25 foam plastic. The fastening of the outer walls is provided to the bearing transverse panels and floor slabs. The floor-by-floor installation of wall panels is designed on a freshly laid layer of cement-sand mortar M 200. The outer end walls are load-bearing three-layer reinforced concrete panels 440 mm thick, consisting of an outer layer 70 mm thick of concrete of class B 25, W4, F100, a middle layer of mineral wool slabs. Concrete Element Butts "and an inner layer 180 mm thick from concrete of class B 30. The outer layer of the basement panels is made of concrete class B 25, W8, F 150, the middle layer is made of PSB-25 foam. The outer and inner layers in the panels are connected using flexible ties made of 6.0X18H100 wire. Sealing the joints of the outer panels is provided by sealing gaskets "Vilaterm-SP", thiokol mastic and caulking with polymer cement mortar. Internal walls - load-bearing, reinforced concrete panels 180 mm thick. The step of the transverse walls is 3,3 m, 3,6 m, 4,0 m, 5,1 m. Wall material - class B30 concrete. Conjugation of load-bearing wall panels and floor slabs - platform joint with the transfer of forces to the underlying floor through the floor slab. Fastening of all wall panels to each other - by welding with welding of steel plates 6 mm thick to embedded parts of wall panels in two levels along the height of the panel. Installation of wall panels floor by floor is provided on a freshly laid layer of cement-sand mortar M 200. Sealing joints with M200 solution. Partitions - reinforced concrete panels 80 mm thick made of class B 15 concrete. Ceiling above the basement - monolithic reinforced concrete slab 250 mm thick made of concrete class B 25, W 6, F100, class A III reinforcement. Ceilings - reinforced concrete flat panels with a thickness of 160 mm from concrete of class B 25, above the technical underground - from concrete of grade F 50. The support of the plates on the walls is provided on 2 and 3 sides, with a support value of 80 mm. The floor slabs are connected to each other in a hard disk by welding with welding of steel plates or reinforcement to the loop outlets or embedded parts of the slabs. Balcony slabs - reinforced concrete flat panels 160 mm thick, with a span of 2,6 m, 3,6 m, 4,0 m, 5,1 m with thermal breaks, supported on both sides by reinforced concrete panels. Balcony railings - reinforced concrete elements 100 mm thick. The material of the balcony slabs and railings is concrete of class B 25, W4, F 100. The coating is reinforced concrete hollow core slabs 350 mm high, with a heater thickness of 230 mm. The material of the slabs is concrete of class B 25, W 4, F 100. Elevator shafts are self-supporting, reinforced concrete three-dimensional blocks, with a wall thickness of 120 mm, made of concrete of class B 25. Ventilation blocks and smoke exhaust blocks are reinforced concrete three-dimensional elements, with floor-by-floor support on floor slabs . The material of the blocks is concrete of class B 22,5. Stairs - reinforced concrete marching platforms made of concrete of class B 22,5. Reinforcement of all prefabricated reinforced concrete elements is provided from reinforcement class A500C, VR-I. Ventilation shafts and smoke exhaust shafts - steel from rolled profiles with support on the grillage plate and fastening to the floor slabs of the buildings. The material of steel structures is steel C 245 GOST 27772-88. The heating point is designed from prefabricated reinforced concrete structures on a monolithic reinforced concrete slab 300 mm thick on a natural base. Underground car park. 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 load-bearing elements with a monolithic coating, the rigidity of the supporting nodes of the columns and stiffness cores (staircase walls). Internal walls - monolithic reinforced concrete 250 mm thick. The columns are monolithic reinforced concrete. The main pitch of the columns is 6,5 x 5,5 m, 6,5 x 6,07 m. The cross section of the columns is 400 x 400 mm. Covering - a monolithic reinforced concrete slab 300 mm thick on monolithic reinforced concrete beams 400 x 600 (h) mm and walls. Stairs and ramps are monolithic reinforced concrete. The material of monolithic structures is concrete of class B 25, B 30, W8, F 100, class AIII reinforcement. The foundations of the building of a residential building and a parking lot were designed based on the results of engineering and geological surveys and pre-design tests of soils with driven reinforced concrete piles with a vertical static indentation load. The design of the foundations of a residential building is a monolithic reinforced concrete slab grillage 800 mm thick on piles. Piles - driven prefabricated reinforced concrete (composite) with a section of 35 x 35 cm, length 17 m (building 6.1) and length 19 m (building 6.2) according to the type series 1.011.1-10 issue 8. The joint of piles is welded, the pairing of piles and grillage is rigid. At the base of the piles - hard sandy loam and loam, hard sandy loam with characteristics e = 0,263, e = 0,330, IL = - 0,32, IL = -0,34, E = 200 kg / cm 2, E = 190 kg / cm 2 According to the results of testing piles with a static load, the design load on the pile is assumed to be 90 tf. Control tests of piles are provided during the execution of pile fields. A concrete preparation 100 mm thick is provided under the grillage. The construction of the foundations of the underground car park is a 600 mm thick foundation slab on a natural base. At the base of the foundation slab - plastic sandy loam with characteristics: e = 0,520, internal friction angle 17, c = 0,18 kg / cm 2, E = 100 kg / cm 2 and fluid loam with characteristics: e = 0,923, internal friction angle 10 deg., c \u0,06d 2 kg / cm 70, E \u2d 0,8 kg / cm 2. The calculated resistance of the soil at the base of the foundation slab is 0,7 kg / cm 2, the average pressure on the base is 100 kg / cm 200. Under the foundation slab provides for concrete preparation with a thickness of 25 mm and crushed stone - with a thickness of 8 mm. The material of the grillage and piles is concrete of class B 100, W 30, F 8, the foundation slab is concrete of class B 100, W 5, F12, reinforcement of class A I, A III. The excavation is provided under the protection of a sheet piling made of L20-um steel sheet piling, 1 m long with strapping beams made of I-beam No. XNUMX KXNUMX.
