Published: November 2020

Abstract
At present, the problem of energy saving is urgent in the world community. The construction and operation of buildings accounts for over 40% of all materials and energy. The problem of energy saving is an integral part of building design. The world experience shows that one of the most effective ways to reduce specific energy consumption in buildings is additional thermal insulation of enclosing structures. The research of different types of modern facade structures of buildings has led to the development of a new type of enclosing structure-a multilayer facade panel (MFP). This article presents the description of MFP construction and the results of the finite element analysis (FEA) with ANSYS solver.
Risk management in monolithic construction
Authors: Topchiy D , Bolotova A 
Published: November 2020

Abstract
Current statistics with regard to the impact of various random factors on the condition of structural units, building elements and structures clearly indicate a number of problems associated with construction safety in general. Prevention of typical frequent accidents requires that methodological recommendations are in place to control or mitigate risks. Risk management in construction operations is to a large extent focused on the relative safety concept. The main tasks are integrated risk assessment, minimization, identification, and analysis, as well as the development and substantiation of managerial solutions. A vital issue reviewed herein is the problem of insufficient use of the risk management system by building companies. This article identifies the main directions of assessing risk events and the degree of damage in construction projects. Analytical research findings have led to a conclusion on the need for development of risk assessment methods to be applied in the organization of construction operations.

The production chain has been built as part of an assessment of the life cycle of a construction project to address the challenges of sustainable construction. The possibilities of using information modeling for the planning and design of building deconstruction are analyzed. A deconstruction control method using information modeling has been developed, which implements control based on a simple and advanced feedback loop.
Pulse control of temperature mode of buildings with elevator system connection heating
Authors: Panferov S V , Panferov V I 
Published: November 2020

Abstract
The problem of energy saving when heating buildings is considered. The problem of weather regulation of heating systems with an elevator connection has been solved, including during the “cut-off” of the temperature regime. An algorithm for impulse control and the composition of automation systems for its implementation have been developed. The duty cycle of the control pulses is determined by the results of measuring either the temperature of the heating system and its flow rate, or the temperature of the coolant at the inlet of the heating system and its flow rate in it. The repetition period of control pulses is selected based on the required quality of regulation in the steady state. This takes into account both the heat-shielding properties of the heated buildings and the characteristics of their heating systems. A qualitative analysis of the dependences of the duty cycle and the repetition period of control pulses on influencing factors has been carried out. At the same time, the approach to solving the problem used in the work, in contrast to the previously used, is more “transparent” and simpler.

Authors: Biryuzova E A , Glukhanov A S 
Published: November 2020

Abstract
Thermal insulation of pipelines is actively used to reduce heat losses in heat supply systems, as well as to reduce the temperature on the utilities surfaces, for safety during daily operation. This method ensures uninterrupted operation of heating systems in the winter, eliminating the risk of the heat carrier freezing and, consequently, their failure. At the moment, the application of effective thermal insulation of heating network equipment and pipelines is of great importance. The lack of a high-quality heat-insulating coating on the pipeline surface leads to significant losses of fund from various level budgets and a decrease in the quality of the heat carrier, that is, its temperature. Special requirements are imposed on thermal insulation materials, according to current regulatory documents, compliance with which is monitored by specialized organizations. The thermophysical indicators study of modern heat-insulating materials of domestic production and their application impact on the efficiency of the heat supply system is an urgent task aimed at improving energy efficiency and reducing energy consumption by reducing heat losses in heating networks pipelines.

Published: November 2020

Abstract
The paper focuses upon modern methods of wastewater purification in the oil-and-fat industry. The researchers draw attention to the fact that if wastewater of food production is not properly purified it starts to decompose and extricate highly toxic substances. They further describe intensification methods dividing them into two groups and discuss pros and cons of the reagent method of wastewater treatment. Significant advantages of probiotic agents in contrast to the reagent treatment method are revealed. Probiotic agents for wastewater treatment are then proposed for use. It is stressed that is a relatively new method and it has not yet been widely studied. The article describes probiotic products composition and their action. It also explains the impact of various groups of bacteria at the stages of mechanical wastewater treatment in anaerobiosis and aerobic biological treatment. The researchers examine variants of probiotics addition and consider advantages and disadvantages of this method. To compare the results, it is proposed to use probiotic agents at municipal sewage treatment plants and at the oil-and-fat production enterprises. These experiments of probiotics application show the potential of their use for intensifying wastewater treatment processes, reducing the level of unpleasant odours and improving sanitary safety of sewage facilities.
Taking into account nonlinear character of heaving pressure development at frost penetration into the soil in confined space
Authors: Kim V , Kim M 
Published: November 2020

Abstract
The article describes the results of a study of the nonlinear nature of the development of frost heaving pressure during freezing of soil in confined space. It was revealed that the development of freezing pressure in firm and firm-stiff clay soils is due to various processes that occur in them when lowering the temperatures. In water-saturated firm clay soils, heaving pressure occurs mainly when free water freezes in a closed pore volume, and in stiff clay soils, it is caused mainly by the pressure that occurs when film water freezes. Equations are proposed for determining heaving pressure in firm and firm-stiff clay soils.

Authors: Brzhanov R T , Nigmetov M Zh 
Published: November 2020

Abstract
The article presents the results of the studies, including the elements of a theoretical calculation, factors of internal strength and deformation field during volumetric vibrations of offshore drilling platforms on a layered basis. The influence of factors such as seismic dynamic impacts at the regional scale and dynamics of the geomorphology of the sea floor have been studied. Structures with spatial resilient links connected rigidly, hingedly or otherwise are subjected to dynamic force action. Depending on the size of the external forces and the forces of inertia, the flexible elements of the structure of the offshore drilling platform are in a complex three-dimensional stress-strain state. In dynamic calculation of the characteristics of the systems, the finite element method was used by replacing the platform with a system with a finite number of nodal points interconnected by inertia less rods. The masses are concentrated at the nodal points.

Authors: Safin D R 
Published: November 2020

Abstract
The study was aimed at assessing the deformability of a weak water-saturated clay base reinforced with a group of sand piles in the form of a continuous pile field, when they are jointly deformed under load. Existing studies consider the interaction of free-standing soil piles with the surrounding soil, methods for their calculation, without taking into account the joint operation of a group of piles in a deformable soil massif. The main research results were obtained in the form of new experimental data on the operation of a group of sand piles during their joint deformation with weak water-saturated clay soil massif under a stamp. The significance of the results obtained for the construction industry lies in the fact that the experimental data presented can be used in further theoretical studies to develop a calculation model that allows taking into account the peculiarities of the interaction of sand piles in a pile field with each other and with the surrounding soil massif and are of practical value.
Mathematical model of underground structure-soil interaction
Authors: Sultanov K S , Khusanov B E , Rikhsieva B B 
Published: November 2020

Abstract
Based on existing data of experimental studies of underground structure-soil interaction, a condition for boundary interaction between the underground pipeline and soil was developed. The proposed condition (a model) of interaction at the contact boundary takes into account the structural destruction of the contact soil layer and the cyclical nature of interaction process. The authors have shown by parametric analysis of the interaction model, that under cyclic interaction of the underground pipeline with soil, the structural disturbance of the soil contact layer does not reach the peak shear stress; the applicability of the problems of underground structure-soil interaction is also shown. The model of interaction on the contact structure-soil surface in particular cases passes into the existing conditions of interaction, including Coulomb friction.
Wedge-shaped surfaces with constant length generators in architectural design
Authors: Korotkiy V A , Usmanova E A 
Published: November 2020

Abstract
The characteristic feature of ruled surfaces is that they are easy to describe and manufacture; therefore, they are widely used in the design of various architectural forms and building structures. Ruled surfaces are formed when a rectilinear generator moves along the guide curves. The shape of the surface does not only substantially depend on the shape of the guides, but also the law of the generator movement. Three conditions should be specified to select a surface from the whole variety of three-dimensional space lines. The article considers the surfaces distinguished from a linear congruence with u, v axes, subjecting only to two geometric conditions, namely: the conditions of the intersection of the rectilinear surface generators with the congruence axes. The third condition is metric: the length of the segments of all the generators enclosed between u, v axes should be the same. The design parameters of a surface with constant length generators are selected based on the theorem proved in the article. We recommend using the proposed solution in the manufacture of temporary or mobile T-tent structures. We presented examples of portable structures (tent circus, indoor stage for public events).

Published: November 2020

Abstract
In the modern age of globalization and high-tech, when information can be obtained in unlimited quantities, there is an acute problem of selecting really important aspects of harmony. In Russian design, unfortunately, little attention is paid to the consideration of things as an image, its functions and attitudes towards culture. It is obvious that harmonious colour perception is developed in the process of studying the colour science, its bases and laws such as the laws of subjective color perception, optical mixing, mutual influence of colors and types of contracts, as well as the ability to assess the size and consistency of the ojectes color relations, the integrity of perception, the vividness and expressiveness of colour, which from the internal basis of the visual image.
