Analysis of the Regulatory Base for Designing Reinforced Concrete Structures The emergence of new building materials, technologies, and design methods leads to the necessity of permanent renovation of the construction regulatory base, and the expansion and deepening of cooperation between the states entails the necessity to harmonize Russian regulatory-technical documentation with international documents. Technical regulation in the field of design and construction with the use of reinforced concrete is of particular importance due to the leading positions of reinforced concrete in the overall structure of the world manufacture of building products. The analysis of domestic regulatory documents on the design of reinforced concrete structures has been made. The systematization of legal, technical and methodical documents, codes of rules, standards related to the design of reinforced concrete structures has been executed. Have been analyzed the most widespread foreign and international systems of regulatory documents in the field of reinforced concrete structures design, their requirements have been compared with requirements of domestic norms. The issues which were partially covered in the existing regulatory-technical documents have been revealed. Documents required to be developed, redeveloped or canceled have been determined. On the basis of results obtained, the hierarchical structure of the complex of regulatory documents in the field of the design of reinforced concrete structures including the basic and three consistently subordinated levels of regulatory documents has been formed. Proposals on correction and addition of the domestic system of regulatory documents, making changes in the existing documents and development of new ones have been developed. Among the most important areas of work on the development of the regulatory base it is necessary to identify the regulation in the field of operation of reinforced concrete structures and buildings, regulation in the field of scientific-technical support of design and construction, regulation in the field of providing the fire resistance and fire durability of reinforced concrete structures.

Keywords: design, reinforced concrete structures, regulatory-technical documentation, standard, code of rules.

Reinforcement of An600C Class in Modern Construction Rebar of An600C class made of 20G2SFBA steel has been developed and is manufactured by Cherepovets Steel Mill of PAO “Severstal”. Due to the chemical composition including niobium and vanadium, this thermo-mechanically hardened steel has high corrosion resistance, fire resistance and ductility. Research in the use of the rebar of An600S class in prefabricated reinforced concrete structures has shown the possibility to reduce the consumption of rolled product in structures with frame-reinforced concrete frames by series 1.020-4 and 1.420-35.95 with overlappings from multi-hollow slabs. Reduction in the consumption of reinforcing bars reaches 13.3% in comparison with rebar of A500C class , and in buildings of the series 1.020-1/ 83 (87) – 9% in comparison with the rebar of A500C class. For multicore slabs, the reduction in consumption of the reinforcement used in the frames of these series in comparison with rebar of A500C class can reach 21%, and when compared with the widely used rebar A600, the savings can be 7%.

Keywords: reinforcing bars, prefabricated reinforced concrete structures, columns, beams, multicore slabs.

Production of Autoclaved Aerated Concrete in Russia in 2017 Volumes of the production of autoclaved aerated concrete in Russia are shown; the dynamics of production of aerated concrete in 2012–2017 is traced. The analysis of production capacities for producing the autoclaved aerated concrete by workload is presented. The structure of release of products made of autoclaved aerated concrete by types (reinforced, for stone masonry), by brands of average density (from D200 up to D800) is given. It is shown that the production of aerated concrete reduced less than the production of other piece materials (by 2.2% comparing with 2016), and the shear of aerated concrete at the market of wall materials increased even more. The analysis of the dynamics of output costs is made, their reduction and the subsequent stagnation in 2013–2018 are shown. It is concluded that the volumes of production of autoclaved aerated concrete retain a high correlation with the volumes of housing construction and their share at the market of piece materials.

Keywords: autoclaved aerated concrete, cellular concrete, statistics, production volume, output prediction.

Research and Development of Pulse Current Generator (PCG) for Installation of Bored Piles The impulse-discharge technology of installation of bored-injection piles opens a new direction in geotechnical construction. Due to its specific qualities, it is an original technology. Unlike other technologies, it makes it possible to install bored-injection piles with an increased bearing capacity. The originality of this technology is the use of pulse current generators to create an electro-hydraulic effect in a borehole drilled and filled with fine-grained concrete. The technology of bored piles with the help of a pulse generator improves reliability and electrical safety by reducing the operating voltage. While forming a high-energy pulse, conditions are created under which a shock wave is formed and developed in the form of an electrohydraulic effect in a medium of fine-grained concrete on the ground of the walls of a borehole. The generator of pulse current and high-voltage discharger are a uniform construction. At the same time, PCG is an electric energy storage device, and the discharger discharges this energy in the form of an electrohydraulic effect. This creates a pile-ERT with increased values of the bearing capacity on the ground. PCG is widely used in geotechnical practice for new construction and reconstruction. Being a unique tool for the installation of piles-ERT and cementation of bases, the generator of impulse currents has a wide practical significance in construction.

Keywords: capacitor bank, working voltage, coaxial cable КВИМ, step voltage, PCG, bored pile, impulse-discharge technology (IDT), multi-site broadenings.

An Empirical Method for Calculating Wetness-Carbonization Stresses Emerges in Panels of Aerated Concrete, with Considering its Rheological Properties The problem of estimating the shrinkage stresses taking the creep into account arising in the outer layers of the wall panels made of aerated concrete with a contemporaneous action of wetness and carbonization processes is considered. A practical calculation method is proposed for the determination of these stresses. The method is based on the classical approach and principles developed by Aleksandrovsky and Arutunyan for solving applied problems in the theory of creep but with considering the influence of wetness and carbonization on shrinkage, creep and stress relieving of autoclaved aerated concrete. The calculations performed by this method made it possible for the first time to obtain information about the development of intrinsic stresses in cellular concrete wall panels. This method allows also to determine their limiting total values at which shrinkage cracks can form on the surface of the wall panels and calculate their depth. This gives us the opportunity to develop technological and constructive activities aimed to improve the longevity of the aerated concrete wares.

Keywords: aerated concrete, carbonization, shrinkage stresses, creeping, stress relieving, crack resistance, longevity.
