Authors: Burlov Vyacheslav , Mankov Victor , Polyukhovich Maxim 
Published: August 2020

Abstract
Sustainable development in the construction industry is hard to imagine without proper electric power supply. The fulfillment of the target by the control object (electric power networks, sources of electricity) can be achieved only if it’s safe. Safety management system should be developed based on synthesis. Only such an approach guarantees the achievement of the goal of activity (timely and high-quality electric power supply of the construction site). The basis of human activity is the decision of the person (decision maker). There is a need to take into account the qualifications of the manager. Human makes a decision based on a model. Therefore, it is advisable to introduce a manager’s qualification indicator into the mathematical model of managerial decision. The manager’s presence of knowledge and skills appropriate to the current situation allows timely response to emerging threats during the operation of the control object. The methodological foundations of creating a model of the managerial decision in managing the safety of the electric power supply process guarantee sustainable development in the field of construction of residential and industrial facilities.

Abstract
One of the current problems of the Russian tax system is optimization of the level of tax burden on agricultural producers. Differentiated business conditions in agricultural production necessitate a review of the definition of the tax base and tax rates of the unified agricultural tax (UAT). The authors propose to calculate the average rate of UAT in the context of the subjects of the Russian Federation (regions) by the country’s average level of climatic conditions, and the natural and climatic potential of the zone should be determined based on the soil fertility index taking into account soil bonitet values and bioclimatic potential. Thus, the results of calculations by regions of the Russian Federation illustrate the following. Regions with the least favorable climatic potential are located within the North-West Federal District-the Komi Republic, the Arkhangelsk Region, the Vologda Region, respectively, and tax rates there should be minimal.

Abstract
The choice of the gating feeding system of castings is made by trial and inevitable errors, which are the less, the more experience of the casting engineer who develops the type of system for different types of casting. The design of the gating system and the modeling of the casting process, the formation of casting, and the analysis of emerging defects can be made more efficiently due to the great possibilities of the computer simulation program “Polygon”. Considering the investment casting, the automated design program greatly simplifies the process of finding the best solution, as the investment casting is a complicated and a multiphase process, which requires taking many steps such as designing a press mold, building a cluster, et cetera. The factory design of the casting model is a stock of unified exemplary segments, which are interconnected and characterized by an unproductive usage of a top part. It is proposed to improve the model casting unit “Flange” of the current production, without changing the design of the model units, and increasing the number of models of the casting from one to four, which can lead to an increase in the yield of fit. In preparation for the calculation, the three-dimensional model was divided into a finite element mesh. The computer program calculates the process of solidification and formation of shrinkage defects for metal. The conducted computer experiment showed that this technology of casting arrangement, developed with the aid of the automated design program, can be used in production, which will significantly accelerate the implementation of the annual program, ensuring the production of high-quality castings, which is confirmed by the experimental fills. Programming processing in SprutCAM allowed to reduce processing time by minimizing idling and to obtain a trouble-free control program for the CNC machine.

Abstract
Successful development of road-construction machinery requires continuous improvement of existing and the introduction of new materials in the production of machine parts. The production of machine parts from polymer composite materials based on various types of binders containing dispersed and fibrous fillers is of a great interest to researchers. Polymeric composite materials consist of two or more components that differ in chemical composition, physical and mechanical characteristics. The main purpose of the filler is reinforcement, i.e. hardening of the material and imparting the required special properties, for example containing fibrous fillers. We took natural flax as fibrous filler in experimental studies. The paper attempts to study the intensity and quality of the grinding technological process depending on the time and frequency of rotation of the mechanism, the factors that influence it, the relationships and the laws of the technological grinding process in drum-type mixers, and increasing the efficiency of grinding material, reducing dynamic stresses.

Published: August 2020

Abstract
The study investigates the pedagogical aspect of forming the professionally significant language skills of future engineers. The results emphasize the determining role of employees who are called “linear personnel”. It stands out that one of the factors ensuring the successfulness and effectiveness of the professional activities of a linear engineer is his ability to act confidently in the foreign environments, receive, process and transmit professionally significant information in a foreign language. In justice to previous research in this direction, we note that they practically do not reflect the problems of developing professionally significant language skills in a technical university that are directly related to the types and functions of an engineer’s professional activity. The results obtained during the experiment showed that situational language teaching characterized by the verbal and cogitative task, problems is an effective means of forming the professionally significant language skills of future engineers. Situations developed and tested by the authors in the training courses build up the language interaction close to as real as in various professional situations.

Authors: Nikolaeva Regina , Sakhapov Rustem 
Published: August 2020

Abstract
Cities are faced with such tasks as providing residents with a quality infrastructure for life support, public transport, and social infrastructure. In order to solve the problems, cities increasingly turn to digital technologies. It has led to the formation of a full-fledged and well-established name for this area of activity-“Smart City”. Using the example of the small town of Zelenodolsk in the Republic of Tatarstan, we carried out the studies to improve transport infrastructure in the context of the transition to the Smart City concept in small towns. To increase the stability of the transport infrastructure, it is necessary to introduce intelligent transport systems. The influence of intelligent transport systems on the transport process in Zelenodolsk was evaluated using the AIMSUN simulation package, which allows simulating traffic. Studies have shown that all indicators characterizing traffic flow have changed for the better. Consequently, the transition to the concept of “Smart City” is applicable not only for large, but also for small cities.

Published: August 2020

Abstract
The method of quality control of building materials is proposed taking into account the indicator of completeness of control. The completeness of the control calculated as the percentage of checked failures. By the example of quality control of ceramic bricks of brand 100, it is shown that the completeness of control of ceramic bricks of grade 100 is from 46.7 to 48.3%. This confirms the requirements of normative document on conducting performance checks (appearance, dimensions, deviations from nominal sizes and shapes, tensile strength in compression and bending, average density) during acceptance tests. Proposed to exclude verification of the width of the brick, which will reduce the complexity of the control.
Sound insulation properties of sandwich panels
Authors: Erofeev V I , Monich D V 
Published: August 2020

Abstract
The sound transmission via building enclosures of finite dimensions has a resonant and inertial components. The resonant transmission of sound takes place in the mode of self-induced vibrations depending on the degree of self-coordination of its own wave field with sound fields present in the air on both sides of the enclosure. The most effective method of sound insulation enhancement of sandwich panels is to reduce the resonant transmission of sound by acoustic separation of the layers. This design solution provides the greatest reduction of the resonance frequency “mass – spring – mass”. Experimental studies for determining the intrinsic sound insulation of sample sandwich panels have been conducted in reverberation chambers in a diffuse sound field. The acoustic separation of sandwich panel layers allowed for the increase of the airborne noise insulation index up to 4 dB: from Rw
= 38 dB to Rw
= 42 dB (for samples with polystyrene foam cores). For the sample with mineral wool core, the increase of the airborne noise insulation index was 8 dB: from Rw
= 39 dB to Rw
= 47 dB. The results obtained allow us to develop rational constructive solutions for enclosures of civil and industrial buildings of sandwich panels, taking into account the spectrum of insulated noise. Improving the sound insulation of sandwich panels is provided without a significant increase of their mass and thickness.
Bended reinforced concrete beams deformability under long-term and environmental influences
Authors: Frolov N V , Smolyago G A 
Published: August 2020

Abstract
The article deals with the problem of determining the bended reinforced concrete beams deformability indices, which are subjected to a combined long-term load and aggressive environment influence during operation. It is noted that due to the concrete creep, the corrosion damages accumulation and cracks formation, the reinforced concrete structures deformability increases in time. In current methods of beams deflections calculating, a stepwise description of stiffness along the span is implemented, which in some cases can lead to significant errors and, as a consequence, to the limiting state. Therefore, during calculations, it is important to take into account the proper stiffness parameters. In this regard, on the basis of predetermined deformations method, a new methodology deformability indices calculation has been developed, in which the hardness in the span is distributed along the parabola. For its validation, special experimental studies of samples of reinforced concrete beams that were under a static load in sulfate and chloride-containing aggressive environments for a long time were carried out. After comparing the corresponding experimental and calculated samples deflections values, it was concluded that the developed method has sufficient accuracy and, thus, can be used for practical calculations of bended concrete elements deformability under long-term and environmental influences.
Reduction of temperature influence in temperature-controlled rooms in the engineering industries
Authors: Ugorova S , Veselov O 
Published: August 2020

Abstract
Typical air conditioning and ventilation systems are used to create and maintain microclimate parameters. Analytical studies have shown that the existing ventilation systems do not provide proper maintenance of the required parameters of the environment, since the influence of the temperature of the enclosing structures is not taken into account. Thus, the paper proposes the structure of the air conditioning System (ventilation), which provides a sufficiently high degree of air purity and excludes temperature increase on the enclosing structures of the thermoconstant room. The technical result is achieved due to the fact that the air conditioning system additionally contains air distributors for supplying air that adheres to the enclosing structures along the perimeter of the clean zone, and devices for removing this air, connected to exhaust air ducts located along the perimeter of the zone at certain intervals. The application of numerical simulation of air parameters in a thermoconstant room was also analyzed using cleanroom software that allows evaluating the degree of temperature impact from enclosing structures.

Published: August 2020

Abstract
A significant source of increased noise in cities is the engineering and technological equipment of enterprises located in immediate vicinity of standardized objects. The expected noise levels from technological and ventilation equipment of an agricultural enterprise located in the city are estimated. A computer model of the territory under consideration is built using the software package “ARM Acoustics”. As the initial data, the results of field measurements were used. The calculation of the expected noise levels near the facades of residential buildings showed the excess of regulatory levels. It is shown the necessity to install noise screens not only near equipment located on the ground, but also near equipment installed on the roof of the industrial building. The calculation was carried out taking into account the location of the U - shaped screens, which provided effective protection against noise. To illustrate the effect obtained, maps of the spatial distribution of noise are constructed.

Published: August 2020

Abstract
The currently used block-conveyor assembling method requires costs for creating an area for blocks conveyed assembly and applying special assembly-and-lifting equipment and tooling; the erection of reinforced-concrete structures by large-sized prefabricated blocks is not possible without a special cross frame and guide casing, imitating a truss structure. The purpose of the research is designing a block-span method of assembling reinforced-concrete roof structures for one-storey industrial buildings, which would allow increasing the labor productivity, ruling out the usage of cranes with increased lift capacity for lifting blocks, reducing the scope of work at heights and increasing the building safety. The developed block-span method of mounting reinforced-concrete roofing structures with secondary trusses implies the assembling of an enlarged roofing block at ground level in the span between previously erected columns, through the full length and width of the span. The block includes secondary trusses, trussed rafters and roof slabs. The block is assembled on the backing 0.5 m high and 0.4…0.5 m off the center line and the width axis of the building. A block is a geometrically stable structure; all joints are connected by welding embedded items. A block is lifted by simultaneous activating of electric hoists. The block is lifted higher than the columns, moved to permanent position and put on top of columns by means of electric hoists. So, the developed method of roofing assembling allows reducing labor intensity by 1.6 times and duration by 1.4 times.

Published: August 2020

Abstract
Currently, regulatory documents for the design of reinforced concrete structures with composite rod reinforcement do not contain unambiguous provisions for the purpose of the design resistances of the reinforcement, there are no instructions for the design of structures to ensure fire resistance. The article presents an analysis of technical documentation and experimental studies to determine the mechanical characteristics of rod composite reinforcement. As a result of the research conducted by the authors, it was found that the tensile strength of rebar decreases in some cases by 35% when the diameter of rebar rods increases from 5 mm to 10 mm. When analyzing technical documentation and test results, the coupling of composite reinforcement rods with screw winding with concrete up to 14.0 MPa is provided. It is proposed to take a value of 50 °C below the glass transition temperature of the matrix polymer as the maximum permissible temperature for heating rebar rods in a concrete structure. The directions of further improvement of the regulatory framework for the design of reinforced concrete structures with composite rod reinforcement are outlined.

Published: August 2020

Abstract
Test methods for reinforcing steel is not suitable for fiber reinforced polymer (FRP) rebars because it can cause destruction of the edge zones of the samples. The polymer matrix and fibers are not able to resist compression across the fibers. Existing test methods for FRP rebars do not contain information about the equipment and composition of the adhesive composition. The purpose of the study is to clarify the adhesive composition and design of the FRP specimen anchor. Methods. There were experimental studies of fiberglass reinforcement polymer rebars samples carried out. The following factors varied: the proportion of the components of the adhesive composition; the area of the adhesive contact of the FRP specimen anchor. Results and Discussion. The proportion of epoxy glue and quartz sand providing the test of automatic transmission is determined. The influence of the thread on the inner surface of the FRP specimen anchor on the adhesive strength in the contact zone «adhesive composition-steel» is estimated. A universal three-dimensional model of the centering plug for manufacturing using additive technologies has been developed. Conclusions. The results of the investigation can be used to upgrade the FRP rebars test methods.
