Joint of External Wall Panels with Monolithic Reinforced Concrete Belt

The design of the horizontal joint of external three-layer wall panels with the monolithic reinforced concrete belt is offered. This design makes it possible to ensure the central transfer of compressive strength, increase the rigidity of floors and external walls, use pre-stressed reinforcement while ensuring heat insulation of the joint. These joints can be used for designing buildings with any number of storeys. It is also recommended for use in earthquake-resistant large-panel buildings.

Keywords: external and internal reinforced concrete layers, heat-insulation layer, insert, water isolation, protruding reinforcement, pre-stressed reinforcement, earthquake-resistant buildings, monolithic reinforced concrete belt.

Heat Transfer in Joints of External Walls of Large-Panel Buildings at Two-Dimensional Air Filtration

The necessity to develop both the methodology of experimental study and the theory of heat transfer through the joint in the course of two-dimensional air filtration corresponding to the physics of this process, for large-panel housing construction in the first place, is shown.

Keywords: two-dimensional air filtration through the joint, heat transfer, heat exchange coefficient, heat losses.

During the commissioning a building there is a great possibility that the building accumulated moisture in the course of construction did not still dry out, and a part of thermal energy consumed by him is spent for drying of building structures. The software based on the improving the model of successive moistening of K.F. Fokin (1) which takes into account the condensation and evaporation of liquid moisture has been developed for the detailed description of processes of heat and moisture transfer in building structures and definition of a part of transmission losses spent for drying.

Keywords: energy audit, three-layer panel, heat conductivity, vapour conductivity, continuity of steam pressure.

A criterion of the concrete strength under triaxial compression is offered. It is shown that the strength depends not only on basic stresses and their relations, but also on an average stress. This influence is expressed the most simply by the function of Lode-Nadai parameter.

Keywords: triaxial compression, criterion of strength, basic stresses, Lode-Nadai parameter.

A new method of calculation of noise spreading in apartments with a cell system of layout is presented. A feature of this method is an account of redistribution of energy in apartment rooms as a system of volumes having the acoustic connection among them. The method and computer program for its realization make it possible to assess objectively the noise regime in buildings with cells and develop efficient noise-protection measures.

Keywords: noise regime, sound field, cell system of layout, reducing noise.

The architecture of noble estates of Russia is considered. Special attention is paid to the city manors of Yekaterinodar, their architectural-artistic and town planning solutions in the system of the city, as well as villas on the Black Sea coast. It is noted that the leading role belongs to the problem of preservation of historical and cultural values and architectural heritage.

Keywords: estate, park, mansion, villa, country house, architectural heritage, architectural monuments.

The numerical methodology of the study of stressed-strained state of beams used for the elastic foundation of a model of half-space non-uniform in depth has been developed. It is shown that the use of this model makes it possible to reduce the distributive ability; an influence of parameters of non-uniformity of the foundation and the flexibility index on the stressed-strained state has been studied.

Keywords: foundation, beam, non-uniformity, flexibility, moment, contact pressure

It is substantiated that the existing approach to the assessment of publication activity of scientific institutions of higher education and scientists including the use of the Russian Science Citation Index does not fully reflect the efficiency of scientific activity. A new algorithm of evaluation is offered.

Keywords: rating of universities, methodology of compilation of university ratings, publication activity, Hirsch index.
