    Abstract. Issues of the efficiency of reinforcement of reinforced concrete structures with minimization of specific consumption of reinforcement, expenditures for construction and maintenance of buildings are considered. At the same time all requirements concerning normalized limiting states should be fulfilled. The use of deformed reinforcement, ensuring the defect minimum fR >= 0,075 rated for production, improves the crack resistance, reduce the deformability of reinforced concrete that makes it possible to use the rolled metal of A500 (A500SP) and A600 classes not only in compressed but also in flexural beam and plate reinforced concrete constructions with a span over 4 m without prestressing.
    Key words: efficient reinforcement, reinforced concrete structures, deformability, crack resistance, progressing destruction, two-side and four-side crescent-shaped section of reinforcement

    Abstract. Modern concretes produced with the use of efficient additives on the basis of mineral substances and organic plasticizer have low permeability. The diffusion mechanism of the transfer of aggressive chemicals dominates in such concretes. Concretes with the coefficient of diffusion for aggressive solutions 10-8 cm2/s and less have a high resistance to corrosion in chlorides and sulphates. Concretes of such quality are not subjected to carbonation.
    Key words: ñoncrete, permeability, diffusion, corrosion resistance, chlorides, sulphates, carbonation.

  • The Use of Non-Destructive Methods for Control of Strength of High-Strength Concrete
  • UDC 691:620.179.1
    Mariya G. KOREVITSKAYA, Bobobek Kh. TUKHTAEV, Sergey I. IVANOV
    Abstract. Modern high-strength concretes and technologies of their laying differ from concretes used in the course of development of the existing standards on the use of non-destructive methods of concrete strength control. It makes necessary to check and specify the procedures of operating normative documents. The usability of normative documents developed previously with due regard for features of modern high-strength concretes is shown.
    Key words: high-strength concrete, control of strength by non-destructive methods, pull-out testing with shearing, shock pulse method, ultrasonic method.
  • Prospects for Reducing Cost and Time of Repair-Construction Works
  • UDC 69.059.25:69.003.13
    Larisa A. TITOVA
    Abstract. One of the methods to reduce or remove the shrinkage strains of concrete structures - the use of self-stressing concrete and its variant - concrete with compensated shrinkage developed at NIIZHB named after A.A. Gvozdev - is presented. The use of such concretes makes it possible to construct the structures and facilities which technical and operation characteristics exceed the analogues constructed from concretes with portland-cement.
    Key words: self-stressing concrete, concrete with compensated shrinkage, underground facilities, water resistance, crack resistance.
  • Issues of Fire Resistance of Reinforced Concrete and Eurocode EN 1992-1-2
  • UDC 699.812:691.32
    Vladimir V. SOLOMONOV, Irina S. KUZNETSOVA
    Abstract. The article is devoted to engineering problems arising in the course of development of the National attachment to Eurocode EN 1992-1-2-2004, Part 1-2 "General rules -Definition of fire resistance". Arguments complicating and at this stage not allowing to develop the National attachment to the mentioned Eurocode are presented. The difference between European and Russian methodological principles of designing reinforced concrete structures is shown from the position of ensuring the fire resistance. The conclusion about the necessity to conduct experimental studies for eligibility of application of the provisions of Eurocode is made.
    Key words: reinforced concrete structures, concrete, fire resistance, designing.
  • New in Methods of Concrete Tests
  • UDC 620.17:691.32
    Aleksey V. ANTSIBOR, Mark I. BRUSSER
    Abstract. New methods of the determination of strength characteristics of concretes including especially high-strength during the tensile test and split test of small-size samples of cylinders are stated. The reduction of laboriousness in the course of selection and preparation of samples for testing, enhancement of the possibility of using this method for determination of strength in dense reinforced structures are distinctive features of these methods.
    Key words: core (kern), determination of concrete strength, high-strength concrete.

  • Defects of Welded Joints of Steel Sheet Structures of Industrial Pipelines
  • UDC 669.018:69.059.22
    Konstantin I. EREMIN, Galina A. PAVLOVA, Aleksandr N. SHUVALOV
    Abstract. The analysis of the causes of breakdowns of technical devices at metallurgical plants shows that they are the result of an unfavourable combination of several factors. Reasons for their appearance and level of their influence on the operation reliability are different but damages as a result of combination of such factors can create an emergency situation at objects with above-standard periods of operation. Data on main defects of welded joints of sheet linear spread metallic structures (SLSMS) of metallurgical plants are presented. The distribution of typical defects of welded joints of SLSMS is analyzed.
    Key words: sheet structures, casing, pipeline, damageability, defect, metallurgy.

    Abstract. Parameters of the urban morphology (a number of variables and qualitative characteristics describing the morphology of the city in detail) are designed for monitoring current changes of an urban form and are used as input data in the process of urban planning and decision making. On the basis of the comparative analysis of different approaches of Chinese scientists to the determination of urban morphology parameters, the "parametric model" meeting the current aims of subjects of town planning regulation in China has been established.
    Key words: morphology of city, parameter of urban morphology, factor, macro and microlevel.
