This Code of Practice has been developed as a development SNiP 52-01-2003“Concrete and reinforced concrete structures. Basic Provisions".
The volume of construction of buildings for various purposes from monolithic reinforced concrete in last years increased significantly. At the same time, design practice does not have at its disposal a document that would combine the basic requirements, the fulfillment of which ensures the reliability and safety of this type of building. This Code of Practice aims to fill this gap.
The decision on the application of this Code of Rules in the design of monolithic buildings is the responsibility of the customer or design organization. In the event of a decision to apply this Code of Rules, all the requirements established therein must be met.

3 Terms and definitions
This Code of Practice uses the basic terms and definitions for SNiP 52-01, SP 52-101, SP 52-104 and other regulatory documents.
4 General instructions
4.1 The recommendations of this Code of Practice apply to the design of various structural systems of buildings, in which all the main supporting structures (columns, walls, ceilings, coatings, foundations) are made of monolithic reinforced concrete with rigid and pliable interfaces between them.
4.2 The design of building structures subjected to climatic temperature and humidity influences should be carried out according to SNiP 2.01.07.
4.3 Calculation and design of buildings under seismic effects should be carried out in accordance with WithnIPII-7 . Fire resistance of structures and fire safety of buildings must meet the requirements SNiP 21-01 and STO 36554501-006.
4.4 The supporting structures of the building should be designed taking into account durability and maintainability in accordance with SNiP 31-01, protection of structures against corrosion should be carried out in accordance with the instructions SNiP 2.03.11.
4.5 The values of ultimate deformations of the base of buildings are regulated SNiP 2.02.01. Limit deflections, movements of structures and distortions of vertical and horizontal cells of buildings should not exceed the allowable values given in SNiP 2.01.07.
4.6 For buildings calculated for the combined effect of vertical and horizontal loads according to an undeformed scheme, it is recommended to take the deflection of the top of the building, taking into account the compliance of the base, no more than 0.001 of the height of the building. For large values of deflections, it is necessary to perform the calculation according to the deformed scheme. In this case, the value of the deflection of the building should not exceed 0.002 of its height.
4.7 This Code of Practice should be used in conjunction with SP 52-101 and SP 52-104.
4.8 Reinforced concrete structures must be designed in such a way as to prevent the occurrence of all types of limit states with sufficient reliability. This is achieved by choosing the quality indicators of materials, assigning dimensions and designing in accordance with the recommendations of this SP and current regulatory documents. At the same time, technological requirements for the manufacture of structures must be met, the requirements for the operation of buildings, as well as the requirements for ecology, energy saving, fire safety and durability established by the relevant regulatory documents, must be met, and uneven subsidence of the base must be taken into account.
4.9 When designing reinforced concrete structures, their reliability must be established by calculation of the limit states of the first and second groups by using the calculated values of loads, material characteristics, determined using the corresponding partial reliability factors according to normative values these characteristics, taking into account the degree of responsibility of buildings.
The normative values of loads, load combination factors and reliability factors of structures, as well as the division of loads into permanent and temporary (long-term and short-term) should be taken in accordance with SNiP 2.01.07.
The order of application of permanent and long-acting loads should be determined by the work schedule or after the fact.
4.10 Along with testing the strength of concrete using samples, it is recommended to control the strength of concrete in the finished structure using non-destructive methods according to GOST 22690.
4.11 When using reinforcement of class A500C with an effective profile developed at NIIZhB, one should use the recommendations STO 36554501-005. Docking of fittings at the end at the construction site should be carried out using bath welding, as well as screw and pressed mechanical joints.
It is recommended to use reinforcement of small diameter of the extended range: 5.5; 6; 6.5; 7; eight; nine; ten; eleven; 12 mm of a new periodic profile with a square-shaped core with rounded corners in accordance with TU 14-1-5500, TU 14-1-5501.
