Whether Relations of Designing with Production during Construction of Large-Panel Buildings are Necessary in Russia

The problem of modernization of series, which are widely used in large-panel housing construction, is facing the Russian builders. It is necessary to abandon the construction of twin-houses using similar products. In Europe there is a notion “a building of repeated use”, but of individual geometry, when each product is designed and produced individually. To create more comfortable and diverse environment in Russia it is necessary to move to individual, industrial architecture. An attempt to find out the difference between levels of design in Russia and European countries is made. It is shown that the use of up-to-day software product Allplan Precast makes it possible for a designer to solve faster and more qualitative the problems facing him.

Keywords: large-panel housing construction, flexible designing, Allplan Precast, specification.

Prediction of Durability of Reinforced Concrete Flexural Elements by Method of Degradation Functions

A mathematical model for describing the operation of reinforced concrete products under the joint impact of mechanical loads and aggressive media is proposed. Constants of the chemical resistance of materials, which are the basic kinetic parameters of the model and make it possible to theoretically evaluate the residual lifetime and durability of reinforced concrete products are substantiated. Examples of calculation are considered. It is proposed to use the results of tests on compression of prisms after exposure in the aggressive medium for verification of degradation models recommended to apply for evaluating the residual lifetime and durability of elements of building structures.

Keywords: corrosion, micro-hardness, isochrones of degradation, diffusion factor, destruction front.

Distinctions of determining of the optimal air exchange in rooms of residential buildings
The problem of the existing norms of air exchange in the room of the residential building, which does not take into account the quality of the outdoor air are described. For the indicator of clean air passed carbon dioxide, the concentration of which characterizes the quality of indoor air environment of a residential building. Outdoor air pollution leads to a decrease of oxygen, resulting in the need to increase the air consumption for CO2 below the required values. Unfortunately, the Russian Federation had not approved the rules of allowable carbon dioxide air pollution for a normal human being indoors, however, foreign States have such rules that allows you to analyze the existing rules on the required air exchange in the apartment. Increase ventilation will reduce the concentration of contaminants in the environment, provided that the concentration of contaminants in the air below the maximum allowable concentration.

Keywords: ventilation, air quality, the concentration of harmful impurity, ventilation of residential buildings.

Construction Complex as a Subsystem of Meso-Economics

Results of the study of the place and role of the construction complex in the meso-economic space of Russia are presented. The character of participation of building companies in the meso-economic system is disclosed. The attention is accentuated on the fact that enterprises of the construction complex, in most cases, are not linked with each other organizationally, but their activity is under the control of a single regional centre of executive authority.
It is shown that in the process of the construction complex functioning production and economic inter-industry linkages and relationships creating preconditions for strengthening the significance of the industry in the economy of the country are forming and developing. Construction companies, functioning independently or as a part of financial-industrial groups, significantly influence on the formation of both regional and macro-economic environment of the country. This makes it possible to reasonably affirm that the construction represents a major economic complex with numerous intra-industry and inter-industry links and is a significant subsystem of meso-economics. The generalization of the study results shows that there is a number of scientific tasks and problems solution of which will make it possible to develop recommendations on the formation of practical orientation of the economic policy of the state at the regional and federal levels.

Engineering Method of Calculation of Joints for Panel Buildings External Enclosing Structures with Due Regard for Air Filtration

A substantiation of a new approach to the assessment of the influence of external air filtration with negative temperature on the heat protection of buildings is made; this method consists in quantitative accounting (division) of air permeability as transversal, longitudinal and total. The simplified method for the assessment of the influence of transversal filtration of external, cold air on the heat insulation of external walls is presented. An example of thermal-technical method for assessment of heat protection properties of horizontal joints for a residential nine-storey house made of one-layer cellular concrete panels, when air filtration is available or not, is given.

Keywords: air permeability, filtration, heat losses, resistance to heat transfer, air flow rate.
