Notes:
1. The loads indicated in position 10 should be taken into account when calculating the load-bearing structures of balconies, loggias and wall sections in the places where these structures are supported. When calculating the underlying sections of walls, foundations and foundations, the loads on balconies and loggias should be taken equal to the loads on the adjacent main premises of the building and reduced, taking into account the instructions of paragraphs. 3.8 and 3.9 SNiP 2.01.07-85*.
2. The normative values of loads for buildings and premises indicated in positions 3, 4, 5 (c, d), 6, 7, 9a, 12 should be taken according to the design assignment based on technological solutions.
3. For the loads indicated in table 5.1, one should take
5.3. The design values of the snow load should be considered as short-term and taken in accordance with the requirements of Section 5 and the mandatory Appendix 3* to SNiP 2.01.07-85*, taking into account the following additions:
Estimated value of snow cover weight in Moscow
should be taken equal to S = 2.0 kPa (200 kgf / sq. m);
For roofs of high-rise buildings with slopes up to 20%, the "mi" coefficient, established in accordance with the instructions of schemes 1, 2, 5 and 6 of the mandatory appendix 3* to SNiP 2.01.07-85*, may be reduced by multiplying by a coefficient equal to 0.6 .
The reduction in snow load provided for by this clause does not apply to the coatings and sections of the coatings of buildings specified in clause 5.5 * b of SNiP 2.01.07-85 *.
5.4. When calculating high-rise buildings for wind loads, it is necessary to take into account general provisions section 6 of SNiP 2.01.07-85* and the following wind effects (Appendix 5.1):
Average and pulsation components of the calculated wind load;
The maximum values of the wind load acting on the structural elements of the fence;
h - height;
d - transverse minimum size;
Impacts that cause violations of the comfort conditions of pedestrian zones.
Aerodynamic coefficients of forces, moments, internal and external pressures, the Strouhal number for estimating resonant vortex excitation should be taken on the basis of testing models of high-rise buildings, including existing buildings, in specialized wind tunnels.
5.5. The load-bearing and enclosing structures of high-rise buildings must be designed for temperature and climatic effects in accordance with the requirements of SNiP 2.01.07-85* in cases where the design solutions do not provide for compensation of forces and deformations caused by changes in the outside air temperature or uneven heating of structures.
5.6. Buildings with a height of 100 meters or more must be calculated for seismic effects in accordance with Appendix 5.2.
The calculation of structures and foundations should be carried out for the main and special combinations of loads. When calculating for a special combination, taking into account the seismic impact, the values of the design loads should be multiplied by the combination factors taken according to Table 2 of SNiP II-7-81*. At the same time, temperature climatic effects, wind loads, dynamic effects from equipment and transport are not taken into account.
5.7. High-rise buildings are structures with an increased level of responsibility, and when calculating their load-bearing structures, bases and foundations, it is necessary to take the following values of the reliability coefficients for responsibility depending on the height h:
Over 75 to 100 m - "gamma" = 1.1;
Over 100 to 200 m - "gamma" = 1.15;
Over 200 m - "gamma" = 1.2.
When calculating the elements of fences and their attachment points
"gamma" = 1.0.
Section 6. DESIGN SOLUTIONS
Engineering-geological surveys. Foundations, foundations
and underground parts of buildings
6.1. A general assessment of the engineering and geological conditions of the construction site and a preliminary selection of the type of foundations should be carried out on the basis of surveys at the pre-design stage. At the same stage, an assessment of the possible manifestation of dangerous geological and engineering-geological processes (karst-suffusion, landslide, etc.) should be carried out to assess the possibility of constructing a high-rise building on this site.
In the design assignment, it is necessary to provide for detailed engineering and geological surveys, which should be carried out at the "design" and "working documentation" stages.
6.2. The results of engineering-geological surveys should contain the data necessary for a reasonable choice of types and sizes of foundations and dimensions of the supporting structures of the underground parts of the building, taking into account the forecast of changes in engineering-geological and hydrogeological conditions and the possible development of dangerous geological and engineering-geological processes (during construction and operation object), as well as the necessary data to assess the impact of the construction of a high-rise building on the surrounding buildings.
6.3. When arranging an underground part under a high-rise building, the program of engineering-geological surveys should include additional requirements for surveys for underground and buried structures.
6.4. Given the significant depths of the compressible thickness of the base of high-rise buildings, part of the field research of soils (probing, soil testing with stamps) should be carried out from the bottom of the pit.
6.5. When using piled and combined pile-slab foundations, piles should be tested with static loads in an amount depending on their total number and the heterogeneity of the base, but at least three tests of piles per object.
6.6. At the construction site of a high-rise building, experimental geotechnical work should be carried out, the composition and volume of which are determined by a special program.
6.7. When constructing a high-rise building in a built-up area, it is necessary to carry out surveys of the bases and foundations of buildings and structures that fall within the zone of influence of high-rise construction, as well as to predict changes in the stress-strain state of the soil massif and the hydrogeological regime of groundwater.
6.8. For a high-rise building, it is necessary to provide for monitoring the components of the geological environment and, first of all, dangerous geological and engineering-geological processes and groundwater dynamics.
Description:
During the period of validity of the Moscow city building codes MGSN 4.19-2005 "Temporary norms and rules for the design of multifunctional high-rise buildings and building complexes in the city of Moscow", significant experience has been gained in the design and construction of high-rise buildings.
A. N. Kolubkov, director of the design and production company "Alexander Kolubkov"
During the period of validity of the Moscow city building codes MGSN 4.19-2005 "Temporary norms and rules for the design of multifunctional high-rise buildings and building complexes in the city of Moscow", significant experience has been gained in the design and construction of high-rise buildings. Thanks to the enormous work done by the specialists of the TsNIIEP housing under the scientific guidance of Yu. G. Granik, this experience, expressed in the form of comments and suggestions, was generalized, submitted for discussion by all interested organizations and was reflected in new edition MGSN with the working title "Norms and rules for the design of multifunctional high-rise buildings and building complexes".
The provisions of MGSN 4.19-2005 were discussed during 2007 at technical meetings at TsNIIEP housing and the Department of Scientific and Technical Policy in the construction industry. To finalize the text of the MGSN, three working groups were created that brought together representatives of design, research, construction organizations as well as investors and customers. The composition of the working groups was agreed with the Department of Scientific and Technical Policy in the construction industry. These were working groups on general, space-planning and constructive sections of the norms; on security and fire safety requirements; on engineering systems of high-rise buildings. Comments and suggestions, as well as a number of discussion issues were discussed at the meetings of the working groups. 9 meetings were held.
In total, the developers of the new edition of MGSN received 835 comments and suggestions from research, design and construction organizations. All these comments and suggestions were considered at the meetings of the working groups and taken into account in the text of the finalized regulatory document.
The new edition of MGSN 4.19 provides for more stringent approaches to the design of high-rise buildings, namely:
When designing high-rise buildings, it is necessary to provide for scientific and technical support.
To design work organizations with at least 5 years of experience in the highest category of complexity may be admitted.
Specifications for the design of fire protection of a particular high-rise building, architectural and technical solutions not provided for in these standards or other applicable normative documents, must be substantiated by the necessary calculations, agreed and approved in the prescribed manner.
Part working documentation a technical passport for a high-rise building and operating rules should be included. AT technical passport indicate all the most significant characteristics of the building and its engineering systems. The operating rules are developed according to a separate design assignment.
Included in project documentation new equipment and materials for which there is no relevant regulatory documentation must have confirmation of their suitability for use in construction conditions and operation in high-rise buildings.
As one of the significant changes, a new approach to establishing the boundaries of fire compartments of a building in height should be noted - the height of each fire compartment of the above-ground part of the building, as a rule, should not exceed 75 m. The previous edition indicated that the height of a fire compartment, as a rule, should not exceed 50 m. In addition, a clarification appeared in the new edition that in the case of placement of crowded premises (restaurants, cafes, etc.) above the first fire compartment, the corresponding fire compartment should not exceed 50 m in height or these premises should be allocated to an independent fire compartment.
The following is an overview of the regulatory requirements for thermal protection of high-rise buildings, heat supply and heating systems.
The new edition notes that the thermal protection of high-rise buildings must comply with the requirements of SNiP 23-02-2003, MGSN 2.01-99 and the requirements
according to the new edition of MGSN (the previous edition of MGSN 2.01-99 was not mentioned). The values of the calculated reduced resistance to heat transfer of enclosing structures (with the exception of translucent ones) R o, (m 2 ° C) / W, which should be at least the normalized values of R req for the corresponding heights of buildings (Table 7.3.1) (t int , ° C is the design temperature of the indoor air).

||||||||||||||||||||||||||||||||||||||||||||
Note. Above the line - when calculating according to the reduced resistance to heat transfer, below the line - the minimum allowable R req . The new edition also included a clarification that at the calculated internal air temperature t int = 20 °C and above, the duration of the heating period is taken at an average daily temperature of ≤ 10 °C. |
||||||||||||||||||||||||||||||||||||||||||||
In the new edition of MGSN, the requirements for filling window openings in high-rise buildings are placed in a separate subsection "External fences and facade systems" of the section " Constructive decisions". In the previous edition, these requirements were both in the subsection "Above-ground structures" of the section "Constructive solutions" and in the section "Thermal protection".
The previous edition of the MGSN stated that “when windows are located above 75 m, blind non-opening covers should be used,” and the use of windows with openable covers was allowed when installing translucent protective screens. In the new edition, these requirements have been relaxed. According to the new edition, when windows are located above 75 m, it is allowed to use the following types:
Windows with fixed non-opening sashes and air valves placed in the windows or in the outer wall.
Windows with blind lower sashes and opening transom.
Windows with inward-opening sashes and a translucent protective screen located on the outside, having air gaps at the top and bottom.
Windows with sashes extending outwards by 100–150 mm parallel to the plane of the façade.
The new edition clarifies that window porches must provide normalized resistance to air penetration according to SNiP 23-02-2003, taking into account the increase in wind speed along the height of the building.
In the section "Thermal protection" there are requirements for the normalized resistance to heat transfer of translucent fences, which have not undergone significant changes compared to the previous edition. In the same section, the requirements for glazing located on the outside of blank walls are clarified. The new edition states that when the blind parts of the walls are located behind the glazing, the space between them must be ventilated. The air gap between the glazing and the wall must be covered every three floors with non-combustible material. When calculating the heat-shielding characteristics of facade systems with an air gap, it is necessary to take into account the effect of heat-conducting inclusions in the form of anchors of the insulation and the supporting frame, as well as metal parts of the supporting frame passing through the insulation layer.
A significant comment to the content of the previous edition of MGSN 4.19, expressed by experts, related to the fact that it is often impossible to fulfill the requirement to ensure uninterrupted heat supply in case of accidents (failures) at a centralized heat source or in supplying heat networks during a repair and recovery period of two (main and reserve) independent inputs of urban heating networks. In the new edition, in the absence of the possibility of a device for a second input of heat networks, it is allowed to use the heat supply through one input. At the same time, it is stipulated that the building should not have consumers of the first category (heating, ventilation and air conditioning systems in which, in the event of an accident, interruptions in the supply of the calculated amount of heat and a decrease in air temperature below the minimum allowable in accordance with GOST 30494-96 [SanPiN 2.1. 2.1002-00] and GOST 12.1.005-88 [SanPiN 2.2.4.548-96]). For consumers of the second category (consumers for whom a decrease in temperature in heated premises is allowed for the period of liquidation of the accident), the fulfillment of the paragraph of the considered MGSN on the decrease in air temperature in residential premises not lower than 16 ° C for the period of liquidation of the accident (no more than 54 hours) must be confirmed by calculation (accumulation capacity of fences, household heat emissions, shutdown of ventilation systems) or compensatory measures in the form of installing an additional heat source in the central heating center for heating needs.
The wording of the provision regulating the determination of the height of the zone of the internal heat supply system has been clarified: the new edition states that the height of the zone should be determined by the hydrostatic pressure in the lower elements of the heat supply systems of each zone.
The paragraph on the supply of heating water to each zone is supplemented with a provision allowing, with an appropriate feasibility study, the installation of one group of heat exchangers operating in several zones.
In the new edition, the item regulating the redundancy of heat exchangers has been significantly revised and expanded.
In the new edition, for heat supply systems of high-rise buildings, it is necessary to provide for equipment redundancy according to the following scheme:
At least two heat exchangers (working + backup) should be installed in each heat carrier preparation circuit, the heating surface of each of which should provide 100% of the required heat consumption for heating, ventilation, air conditioning and hot water supply systems, determined in accordance with the provisions of SNiP 41-02- 2003.
When installing backup capacitive electric boilers in the hot water preparation circuit, redundancy of heat exchangers of DHW systems may not be provided.
It is possible to install three heat exchangers (2 working + 1 reserve) in the heating medium preparation circuit for the ventilation system, the heating surface of each of which must provide 50% of the required heat consumption for ventilation and air conditioning systems.
The previous edition of MGSN 4.19 contained a requirement that equipment for preparing water for internal heating systems of each zone should be installed in separate rooms, as a rule, on technical floors, which also allowed to place equipment for ventilation systems, pumping units and drinking and fire tanks. plumbing. This paragraph has been revised in the new edition. According to this paragraph, the equipment of heat and water supply systems, as a rule, should be located at the bottom of buildings in the common room of the ITP (CTP). With a significant height of the building, based on its design features, the equipment for preparing water for the internal heating systems of each zone should be installed, as a rule, on technical floors in separate rooms. In these rooms it is allowed to place equipment of ventilation systems, as well as pumping units and tanks for drinking and fire water supply. When emptying zone systems, water should be discharged by separate pipelines for the systems of the primary (heating) and secondary (heated) heating and ventilation circuits directly into the ITP (CHP) pit. For cold and hot water supply systems, an independent drainage (discharge) pipeline with water discharge to the pit should be provided. In this case, the point of rupture of the jet should be considered a drainage pit.
