General information.

The designed residential building consists of two sections. The level of the finished floor of the 0,000st floor is taken as the conventional level of 1. The absolute mark of 0,000 of a residential building for sections A and B = 142,00. Structural hazard class of the building is C0. Functional fire hazard class – F 1. 3 (apartment residential buildings). Fire resistance degree - II. The width of non-apartment corridors is 1490 mm. Fire compartments are divided into sections. The section has one fire compartment. The designed residential building has a linear configuration in plan. The highest point of the building is 17,700, relative to the level of the first floor +0.000 (mark of the ventilation ducts as part of the parapet of the roof exit booth). The building is five-story with a technical (not heated) underground at elevation. - 2,200. The height of the residential floors is 2,8 m (2,5 m when clear). Floors 1 to 5 are residential. The section consists of apartments 2-1-1-1-2. The entrance to the section is from the first floor. Apartments have from 26.40 to 49.18 m2 of heated area. In each section there is one apartment on the 1st floor for MGNs with two living rooms, one of which is at least 16 m2 intended for the residence of a disabled person and the second living room of at least 12 m2 is intended for the residence of a person caring for a disabled person. There is no living room (common room) in this planning solution. Independent access of MGN to the building is provided only on the first floor according to a letter from the State Public Institution SO "UKS". Each apartment has a standard insolation time. All apartments are provided with modern types of engineering amenities and summer premises - loggias. On the 1st floor of the section, in addition to housing, there is an electrical panel room and a storage room for cleaning equipment, as well as a room with a lift for MGN.

Structural diagram of a residential building with load-bearing brick walls and floor and roof slabs. Masonry of external and internal walls above elevation. 0,000 made of solid silicate brick (GOST 379-95) frost resistance grade MRZ-35 in accordance with the table of brick grades, below the 1st floor - from solid ceramic brick M 100 with mortar M75, MRZ-50 (GOST 530-2012) . The partitions will be laid using gas silicate blocks. Place a reinforced concrete belt under the ceiling of the technical underground; at the level of the bottom of the floor slabs above the 3rd floor, make reinforcements in a layer of cement-sand mortar. The ceiling in a residential building is prefabricated reinforced concrete made of hollow core slabs according to series 1.141-1 issue. 60, no. 63. The staircase is designed from prefabricated reinforced concrete flights of stairs (series 1.151.1-6, v.1) and reinforced concrete landings (series 1.152.1-8 v.1) The calculated forces from external loads and influences are determined taking into account the joint work of all vertical elements combined into a single load-bearing system by floors, lintels and reinforced concrete belts.
