Authors: Shelekhov I U , Smirnov E I , Shelekhov M I 
Published: November 2020

Abstract
The article presents the rationale for the use of thermoelectric systems to provide backup power supply for actuators and automation systems for engineering systems of multistory buildings. The experiments were carried out using the developed stand, which modulated the parameters of the engineering systems of multi-storey buildings. The stand consists of a NEPS-100-220-0.03-UHL4 heating element and a CoolerMasterI30 cooler, the temperature on the sides of the thermoelectric module is controlled by a TPM-2 thermostat using a solid-state relay, the thermoelectric power value is recorded by an OVEN IMS device. F1, the electrical load is set by the resistance bridge. Temperature control of thermoelectric elements, hot and cold sides of a thermoelectric module, as well as sources of “heat” and “cold” is carried out by thermocouples, the data is recorded by the TPM138 meter-regulator. As a result of the work carried out, it was found that with the help of new technical solutions it is possible to increase the temperature on the heat exchange sides of thermoelectric modules and bring their technical parameters to the area of maximum efficiency. When organizing thermoelectric systems, it will be possible to provide backup power to the equipment used in heat points of multi-storey buildings.
Concerning the issue of alternative cold supply for building climate control systems

Published: November 2020

Abstract
The possibility of using alternative cold supply in the life support systems of buildings for the climatic conditions of the Central Black Earth region is considered. The results of calculations and selection of an absorption chiller with an array of solar collectors for an office building planned for construction in Voronezh are presented. The analysis of the efficiency of the heat collectors by the average efficiency showed that for the cold supply of the building taking into account the actual actinometric indicators of the region the use of flat devices was the most appropriate. Vacuum collectors for the solved task under the indicated climatic conditions, despite the generation of a high-potential thermal regime, upon reaching the maximum temperature of the coolant, are characterized by a decrease in efficiency as a result of significant losses to the environment. With justified priority use of flat devices capturing solar radiation, for a deeper extraction of alternative energy, an innovative design of devices of this class is proposed making it possible to increase their efficiency. The use of such devices will reduce their number in the array.
The methodology of redundant design schemes and the method of contour minimization for tracing systems of field gas and oil pipelines
Authors: Chupin V R , Maizel D I 
Published: November 2020

Abstract
The goal of the work is to develop a methodology and a method for optimizing the tracing of oil and gas field pipelines. The analysis showed that the solution to this problem does not receive due attention from both designers and specialists in the automation of design solutions. The paper proposes to solve this problem on the basis of redundant design schemes that represent a graph of possible routes for the passage of field pipelines. As a method, the procedure of the contour (coordinatewise relative to the contour variables) minimization of the cost function of the life cycle of the pipeline system is proposed. A procedure for rejecting inefficient connections in the column of an excessive scheme of field pipelines is proposed. The proposed methodology and method are implemented in the TRACE-NG software package, which is successfully used in practice to substantiate the structure and parameters of pipelines for various technological purposes. Findings. The proposed methodology, method and software package are an effective computing tool useful for designers.

Abstract
The process of de-ironizing natural water by filtering through small-sized cartridge ceramic filters is considered. The process of filtration of the suspension through the filter wall, assuming that the filter wall and the sediment is not compressible. Considering, thus, the flow rate of filtrate is proportional to the pressure gradient of the square of the filter and inversely proportional to the resistance. In contrast to the works of V. A. Zhuzhikov, here the slurry is fed inside the cartridge filter. The results of theoretical and experimental studies are presented. Mathematical equations of filtration process are obtained when source water is supplied inside cartridge.
Mathematical modeling of water supply and sewerage systems
Authors: Teplykh S Yu , Bochkov D S , Bazarova A O 
Published: November 2020

Abstract
The paper describes special aspects of mathematical modeling of water supply and sewerage systems. These systems are complex units consisting of extensive pipeline networks, structures, installations, and equipment supposed to work coherently. This task is challenging due to the large number of parameters and technological processes that occur in sewerage and water supply systems. Therefore, in practice, different types of modeling, including mathematical modeling, are used to cope with these tasks. Modeling is a form of reflection of reality. A developed model can only be useful if it precisely corresponds to the real system. The more perfect the model, the closer it is to the reality.
The estimation of efficiency from application the local strengthening of strip foundations by short piles
Authors: Evtushenko S I , Shutova M N , Pikhur V N 
Published: November 2020

Abstract
Currently many multi-populated Russian cities have an acute shortage of usable space in the central part. The superstructure of one or several floors can become a solution, but it entails a danger of overloading the foundations and the occurrence of uneven precipitation. In this connection, the authors proposed a new model for strengthening the foundations of reconstructed buildings: short piles are pressed or stuffed in local areas, the pile heads are tied with a grillage with the existing foundation. The article discusses the practical and theoretical solution of this problem. Two design models were produced on a 1: 5 scale: a strip foundation model and a strip foundation model locally strengthening with short piles. The experimental results are obtained. A sand base was also calculated using the finite element method by PC PLAXIS. The calculated and experimental data have sufficient convergence of the results. Based on the calculation and experiment, it was found that the draft of the strengthening foundation is 1.875 times less than the draft of the strip foundation, which proves the effectiveness of this method of strengthening with an increase in the load on the foundation by 1.5-2 times.
Computer modelling of architectural forms based on ruled surfaces with imaginary axes
Authors: Korotkiy V A , Khmarova L I 
Published: November 2020

Abstract
One of the methods for constructing ruled surfaces is to isolate them from a linear congruence by immersing a guide line into the congruence body. The article considers a linear congruence defined by four intersecting lines. A theorem on the existence of a beam of planes intersecting a ruled algebraic surface of the order k+2 along algebraic curves of the order k (Theorem 1) is proved. The power frame of such surfaces is formed by rectilinear rods and arcs of second-order curves, which is their technological advantage. An algorithm is proposed for the transition from a linear congruence defined by four lines to an identical congruence defined by collinear fields ∏↔∏’. Such a transition makes it possible to solve the practically important problem of constructing a ruled surface passing through two conical sections. The theorem of an existing congruence defined by collinear fields with second-order curves drawn in them (Theorem 2) is proved. Based on Theorem 2, the construction of a ruled surface passing through predetermined conic sections r, r’ is performed. Examples of constructing biaxial ruled surfaces with real and imaginary axes are considered. Architectural forms based on ruled surfaces with imaginary axes are proposed. The practical use of ruled surfaces with imaginary axes allows expanding the scope of ruled structures in architectural design.

Authors: Kheyfets A L Kheifetc 
Published: November 2020

Abstract
The results of the experimental study and testing of the theorem by M. Chasles are given. The theorem shows the peculiarities of the intersection of an arbitrary tetrahedron with an arbitrary quadratic surface (second-order surface). The multiple variants of the intersection stipulated in the theorem have been considered. It has been experimentally proven that for the majority of these variants the four intersecting lines constructed according to the algorithm of this theorem belong to the surface of a single one-sheeted hyperboloid. For two of the variants, the results that differ from the theorem have been received. The experiments implied building and studying 3D computer models obtained using the AutoCAD and SolidWorks packages. All the variants of the quadratic surface at different mutual position with respect to the tetrahedron have been considered. The methods of holding the experiments have been considered in detail. The proof of the theorem for one of its variants has been obtained and presented.

Authors: Dormidontova V 
Published: November 2020

Abstract
The article discusses the architectural and landscape organization of the district of energy-efficient houses Norra Djurgårdsstaden in Stockholm. Since the end of the 19th century, the Norra Djurgårdsstaden district, with an area of more than 2 thousand hectares, has been part of the industrial area of the Royal Seaport. At the beginning of the 21st century, it was decided to modernize this area and destroy previous industries. Construction began in 2011 as part of the Living City strategy, which envisaged a balanced integrated design and construction of housing, trade, offices, services and public places. The strategy of resource management and responsibility for the climate meant that the city should develop in the direction of a resource-efficient and non-toxic future free of fossil fuels. Using the energy characteristics of buildings, monitoring the amount and recycling of construction and household waste, as well as soil restoration, has significantly reduced the impact on the environment. It was revealed that the architectural and landscape organization, based on the principles of individualization of “spaces of movement” and “spaces of being”, ensured maximum contact with nature, conservation of biodiversity, ecological, visual and social value of streets and courtyards.

Published: November 2020

Abstract
The article is dedicated to the issue of evaluating yard area quality of apartment buildings. According to the analysis of methods of evaluating quality of the urban environment as well as the analysis of urban residents, we have determined the factors contributing to the quality of yard areas and determining satisfaction of residents with their living environment. Using the method of qualimetry, we calculated weight coefficients of various factors from the point of view of their significance to urban residents. We suggest comprehensively evaluating yard area quality using significance (weight) coefficients. The results will allow defining a set of measures intended to improve yard area quality. From the point of view of their significance to urban residents, these coefficients may be used in the housing pricing policy.

Arborsculpture: a promising trend in the interior gardening of buildings
Authors: Smolina O O 
Published: November 2020

Abstract
The article is dedicated to a special form of decorative gardening - winter gardens. Their formation will allow organizing an interior private space for human recreation and meeting the need for a comfortable rest and recovery. Designing winter gardens in residential buildings, in shopping and business centers etc. creates the possibility of year-round human-nature interaction, regardless of season, weather conditions, or daytime. Landscaping of winter gardens is diverse. According to current trends, it is necessary to consider the possibility of integrating arbor sculpture objects into the general composition of winter gardens of various stylistic directions, taking into account environmental, strategic, landscape-functional, visual and aesthetic aspects. Arborsculpture is the art of forming architectural and artistic objects of tree and shrub species adapted for humane growth correction. The use of arborsculpture is possible both in open and closed spaces. However, interior operation is characterized by a shorter formation of arbor sculptural objects and is most often represented by decorative sculpture and/or functional design objects. The use of arbor sculptural objects in winter gardens will improve the ecology, increase the aesthetics of the environment, create unique design solutions, as well as contribute to a more careful, responsible attitude of citizens to wildlife elements.

Construction project as a tool for forming a comfortable and accessible environment: risks and threats
Authors: Filimonova L A , Deviatkina (Abusheva) Y A 
Published: November 2020

Abstract
This article raises the problem of the ambiguity of the use of design documentation for reuse, the superficial attitude of architects to the need for deep processing of documents. When adapting a project to building conditions, important aspects such as insolation, prevailing winds, annual rainfall and temperature conditions, innovative resource-saving and construction technologies are omitted. Unfortunately, many investors, customers and contractors neglect these provisions, and the regulatory and legal framework is not enough to achieve the goals of creating a comfortable and accessible environment. Often, projects that were previously recognized as cost-effective do not correspond to modern realities. The article sets out the basic principles for implementing socially-oriented projects for the construction of a public building, summarizes and systematizes a set of regulatory legal regulation of urban development, formulates the primary tasks of adapting the project to the conditions, substantiates the importance of a creative approach to project development. The authors of the article, using the reuse project as an example, raise the problem of “moral aging” of design decisions and the superficial attitude of architects to the adaptation part. The author’s project of the scientific and educational center is focused on a new reading of the technical and technological parameters that meet the requirements of modern society.
The architecture of banking institutions in Changchun city (1932-1945)
Authors: Tceluiko D S 
Published: November 2020

Abstract
The article is devoted to the architecture of banks in Changchun from 1932 to 1945 (Manchou). At this time, Japan had a great influence on this territory, which invariably influenced the new bank buildings. Four buildings were built: Manchuria Daxing Bank and Manchurian Industrial Bank, Yitong bank and two buildings of Central Bank of Manchou. The article describes each of these objects. The study describes the design solution, functional blocks, outdoor materials, interior, as well as the history of the building and companies located inside. Many of the banks that existed earlier were disbanded, and as a result, their buildings were used for other purposes and subsequently lost their value, which generally made Changchun less diverse from an architectural point of view, if we only consider financial institutions. Typology of a banking institution has clearly developed, with a large hall, spaces for employees and customers, as well as a developed storage system.

Protection of residential buildings from vehicle emissions using landscaping areas of various design
Authors: Balakin V V 
Published: November 2020

Abstract
The gas protection efficiency of green spaces on highways and transport infrastructure objects in residential areas and historical centers of cities has been studied in this article. The most effective protection of roadside areas from gas contamination is provided by dense landscaping strips. The rows of plants closest to the edge of the roadway should be represented by shrubs that form two-tiered hedges, and trees with a low crown. In such rows, the height of woody plants should be gradually increased to form a step-shaped strip per cross section. In order to expand the zone of gas-protective influence of landscaping strips, it is necessary to provide for ordinary planting of high-growing trees in their composition. If the street width is not sufficient to accommodate linear-lane structures of green spaces with the maximum density with a value of the openness coefficient K, close to 1, it is necessary to form landscaping strips of optimal density with a value K=0.5…0.6. On streets with multi-section front buildings in green belts, the most preferable is the height of trees at the level of the middle floors, which provides lower concentrations in front of the strip and uniform dispersion of ingredients at the walls of buildings, as well as intensive air exchange in the pedestrian traffic zone.
