Experimental studies of reinforced concrete elements in bending with torsion under static and dynamic loadings

The results of experimental studies of reinforced concrete elements in bending with torsion under static and dynamic effects are presented. Experimental studies were carried out at the Department of reinforced concrete and masonry structures of the Tomsk State University of Architecture and Civil Engineering. It is shown that a destruction of reinforced concrete beams occurs with formation of complex spatial cross section, which cracks are at an angle of 45 degrees. A number of aspects that may be useful for dynamic analysis and design of structures are shown.

Keywords: reinforced concrete, bending, torsion, static loading, dynamic loading.

New material for the construction of housing
New material taumalit is presented. It is made on ZhBK JSC Saturn-R (Perm). The history of production of wall panels from this material is given. It is shown that in spite of the higher cost of a taumalit in comparison with other building materials , (its price is 1,5 times more than a gas concrete), in many parameters from the point of view of economy he even wins. If to compare the cost of walls of the house of 100 sq.m, construction from the taumalit blocks will be at 5–6 times cheaper than construction from a ceramic bricks. In this case the speed of construction is the same as in panel housing construction.

Keywords: taumalit, the wall panel, gypsum materials, environmental friendliness, waste of the woodworking industry.

System Approach of “Elticon” Group of Companies to Reconstruction and New Construction of House Building Factories

On the basis of the unique experience accumulated by specialist of the “Elticon” Group of Companies, in cooperation with leading European companies, the system approach to reconstruction and new construction of house building factories and large-panel prefabrication plants has been developed. The essence of the approach is that the process of reconstruction or new construction begins from the preliminary stage, the so-called pilot project. The development of the pilot project is systematized and conventionally presented in the form of 10 consecutive steps from the target setting up to development of a sketch plan of new production.

Keywords: reconstruction of large-panel prefabrication plant, pilot project, flexible production, structural system of a building.

Energy efficient ventilated envelopes with active recovery of the heat flow an insulation

For achievement of norms on a energy efficient envelopes (walls and roofs) the considerable layer of a heater is used that in today's conditions is not always economically and energetically effectually. For this reason in recent years the increasing attention including in our country, it is given to new ideology which received the general name «systems of «active» energy saving» (SAE). Generally systems which use secondary energy resources treat SAE, nonconventional and renewables, and also auto-regulation at change of conditions – as outside, and in buildings. Basis of the offers stated in the present article, the energy efficient ventilated envelopes (EEVE) with active recovery of a heat flow which can be widely used for construction and reconstruction of buildings and constructions with the minimum energy consumption are. Offered envelopes actually become stitched devices of system of ventilation with the subsequent active recovery of heat going earlier to the atmosphere through external protections of buildings. The moist mode and heat-technical uniformity of external envelopes of buildings also improve.

Keywords: еnergy efficient ventilated envelopes, system of active energy saving, recovery of transmission heat.

Influence of Filtration and Exfiltration on Heat Protection of Enclosing Structures with Due Regard for Porosity of Materials

The process of heat transfer through the porous external enclosing structure in the course of filtration and exfiltration is considered. At that, for determining the level of heat protection of enclosures at air permeability the author takes into account not only the heat transfer coefficient but also the porosity of material. The calculations conducted show that when the material porosity is taken into account, temperature values obtained on the inner surface of the enclosure and its resistance to heat transfer considerably better correlate with experimental values and are not overrated.

Keywords: material porosity, heat protection properties, infiltration, exfiltration, air permeability, porous wall, temperature.

Stress-Strain State of Soil Mass When Sinking a Pile into the Guiding Borehole

Statements and solutions of contact problems of the stress-strain state (SSS) of the soil mass interacting with a pile with due regard for elastic-plastic properties of soils are presented. The sinking of the pile into the guiding borehole by jacking leads to the initiation of complex SSS in the soil surrounding the pile and under the pile tip which defines its bearing capacity under the impact of external load. At present, the bearing capacity of jacked piles when arranging guiding boreholes is determined by the tables of normative documents or by the results of field tests of the pile, i.e. without accounting of SSS, which is formed around the pile. The analytical solution of the problem of interaction of the jacked pile with soil ground with due regard for linear and non-linear properties of soils makes it possible to evaluate quantitatively the bearing capacity of jacked piles depending on the parameters of strength and deformability of soil without the use of tables and normative documents.

Keywords: stress-strain state, guiding borehole, jacked piles, deformability of soils.
