  • About New Normative Value of Wood Elasticity Modulus
  • UDC 624.011.1:539.32(083.75)
    Dmitry K. ARLENINOV
    Abstract. A new value of the wood elasticity modulus along the grains is introduced into the RD 64. 13330 when designing wooden structures. The author shows that the new value of the elasticity modulus augments values of coefficients j and x, and at the same time reduces the value of deforming bending moment that, at the stage of calculation according to new norms, leads to reduction in reliability of structures.
    Key words: wood elasticity coefficient, compressed-bending wooden elements, deformation bending moment, flexibility, dimensionless coefficient.

    Abstract. Results of the monitoring of simulation of heat insulating materials work in the structures of a flat roof and ventilated and plaster facades are stated. It is established, that the maximum effect on properties of items and their stability is exerted by the strength of mineral wool slabs in the course of compression in the structures of flat roofs, by pull strength of layers - in structures of plaster facades, by air permeability and grains erosion - in structures of ventilated facades. Data obtained make it possible to substantiate the reasonability of using slabs of double density on the basis of mineral wool in the studied structures.
    Key words: double density slabs, insulating shell of buildings, design of flat roof, ventilated and plaster facades, mineral wool.

    Abstract. When designing structures, statically indeterminate systems in particular, with the use of a computer it is not always possible to verify calculations. Results of the work connected with the derivation and analysis of ready made formulas for calculation of statically indeterminate rafter systems are presented. The use of these formulas makes it possible to exercise control over computer-aided calculations and as well as quickly calculate internal forces (a bending moment, transverse and longitudinal forces) of all points of the structure and determine the reaction of supports and linear displacements. Correctness of formulas presented has been verified with the help of the software complex "SCAD".

    Abstract. Approaches to the assessment of bearing capacity of vaulted steel-concrete coverings are considered. It is proposed to account the bearing capacity of cylindrical concrete vaults in the structure of steel-concrete coverings for constructive decisions with a spacing of secondary beams over 1.4 m. This recommendation is confirmed by calculations of cross-sections of concrete with the use of a deformation model making it possible to account the work of concrete in tension.
    Key words: bearing capacity, covering, vault, beam, span.

  • Heat-Shielding Properties and Air Permeability of Ceramic Blocks Izotereks in Wall Masonry
  • UDC 691.421-412:699.86
    Igor L. SHUBIN, Aleksey I. ANANIEV
    Abstract. Results of the study of ceramic blocks "Izotereks" with cells filled with mineral wool inserts are presented. A wall fragment with plaster layers has the reduced total thermal resistance equal to 2,32 m2C/W under operating conditions B. The similar fragment of a wall with an additional facing brick layer under the same humidity service conditions has Ro = 2,95 m2C/W. The experimental value of the factor of heat conductivity of the masonry is 0,19 W/(m).
    Key words: blocks "Izotereks", heat-shielding properties, air permeability.

  • Development of Domestic Systems of Cold Accumulation
  • UDC 628.82/.84
    Vladimir V. EFREMOV
    Abstract. An innovative design of a cold accumulator principally different from the known domestic and foreign analogs has been developed. The operation of the cold accumulator is based on the use of heat of the phase transition (freezing) of water. The use of cold accumulators in air-conditioning systems makes it possible to bring down the cost of a live cycle of a building, to reduce costs for electricity, as well as reduce initial investments in equipment and connection of power capacities.
    Key words: air-conditioning system, cold accumulator, phase transition of water (freezing).
