Authors: Choker H M , Hatoum H M , Abboud M R 
Published: December 2019

Abstract
The terrestrial laser scanner (TLS) method was developed to be the optimal digital technology to protect and preserve various objects, including cultural heritage monuments for about 20 years ago. This method allows the high precise measurements of cultural features at archaeological sites in the aim of preserving them for the future generations. However, the traditional geodetic techniques, such as GPS and Total Station (TS) are still needed for assuring the geo-referencing of the resultant model. This article presents the results of the study of the state of the Temple of Jupiter in Baalbek castle, Lebanon. In addition, a 3D virtual model was created using terrestrial laser scanner [1]. A new method for monitoring strain is also proposed for direct and rapid detection of any changes in building structures [3].

Abstract
Heat and mass transfer in the nature and engineering with the help of the following physical mechanisms: convective heat transfer, mass transfer, radiant heat transfer (transfer of energy by radiation) are studied in the given work. In various cases each of these physical mechanisms can make major or minor (which may be neglected) contribution to heat and mass transfer. Simplified calculation formulas of heat and mass transfer are received for the following cases: heat amount transmitted by radiant heat transfer is small and may be neglected; convective heat transfer is not significant; mass transfer has poor influence on heat transfer.
Results of expedition research of thermodynamic conditions influence in atmosphere on charge transfer under the influence of mechanical forces
Authors: Panchishkina I , Petrova G , Petrov A , Egorov E 
Published: December 2019

Abstract
Observation results accumulated to date show that the processes of mechanical charge transfer in the surface atmosphere play an important role. Mechanical transfer current can be considered as a local generator of electric field acting everywhere in the surface atmosphere layer. Operation regularities studies of such a generator will make it possible to evaluate its effect on the formation of the electrode layer structure. To do this, it is necessary to identify the connections between the mechanical transfer current and other physical factors, which is a complex multiparametric task, the solution of which is facilitated by the analysis of experimental data on the electrical and meteorological characteristics of the atmosphere surface layer. The paper discusses the results of current density measurement of mechanical transfer from the atmosphere to the ground, obtained during a long-term expedition experiment in the Rostov region. Simultaneously with measurements of current density, meteorological parameters were recorded: air temperature, wind speed and direction, vertical air velocity at different levels. To assess the effect of meteorological parameters describing the thermodynamic state of the surface atmosphere on charges transfer under the influence of mechanical forces the method of one-way analysis of variance was used. The F-test calculated according to measurement results in the Rostov region for each investigated case made it possible to reveal the high reliability of this effect.

Use of composite materials for reconstruction of flooring in industrial buildings
Authors: Abramyan S G , Burlachenko O V , Oganesyan O V 
Published: December 2019

Abstract
The paper highlights the relevance of using composite materials for reconstruction of heavy-duty concrete and reinforced concrete flooring in industrial buildings, stating that at the current stage of construction development special attention is paid to the use of steel fiber concrete flooring, as this material allows for reconstruction of industrial floors with minimum financial and labor expenditure. The novelty of the research lies in the fact that the adhesive between the flooring to be restored and reinforced and the new steel fiber concrete layer is a composite polymer-bitumen material with cement and graphite powder additives, which was previously experimentally developed by the authors. This material, given an adequate thickness, also serves as a structural spacing to level the surface of the underlying layer and reduce friction under the bottom of the upper steel fiber concrete layer and the existing floor. The paper describes the reconstruction workflow. The composition of the steel fiber concrete layer has been assumed based on the research of other authors. Although experiments proved the integrity and strength of the flooring after its reconstruction with the new technology, it is noted that the final characteristics of the proposed floor structures and workflow can only be assessed in the course of normal use, which can be the basis for further research aimed to optimize the thickness of the suggested composite layers. The experiment delivered certain labor and material cost figures for evaluating the economic efficiency of the use of the composites described below in the concrete flooring reconstruction.

Published: December 2019

Abstract
The article contains the discussion of materials on the principles of selection of multi-purpose design solutions for the construction industry when conducting a judicial construction and technical expertise, as well as the presentation and an algorithm for solving problems of this type. Based on the interpretation of results of theoretical works and analysis of judicial practice, a method was obtained that can be used when conducting a judicial construction and technical expertise in order to solve the issues of selecting design solutions and materials. When using this method, all rearrangements of variants are checked by their preference and compared with each other. The considered method has been continually applied in solving practical issues of judicial construction and technical expertise. Actually, this type of tasks is often found in the framework of arbitration processes when solving issues on the effectiveness of the use of budgetary funds. The use of the proposed algorithm is the most optimal for the preparation of conclusions of a forensic construction expert for cases of this category.
Supply volume forecasting of building materials
Authors: Kabanov V N 
Published: December 2019

Abstract
Fault times occur due to the late delivery of building materials for which it is impossible to create a stock on a construction site (for example, a concrete mix) when erecting buildings made of monolithic concrete and reinforced concrete. High reliability of supply volume forecasting of building materials per unit time is required to reduce non-production fault times. Based on the equality intensity of the work performance and the structural materials supply intensity, the goal is to develop a generating forecast method of the demand for building materials, taking into account a given level of organizational and technological reliability. The use of classical methods of probability theory made it possible to develop a non-complex mathematical apparatus, which use reliably ensures high confidence of demand forecasts for building materials. The study results can be used in relation to building materials for which it is impossible to create a stock on the construction site, for example, a concrete mix. The practical application of these research results is capable of developing production plans reflecting the real possibilities of contracting organizations, including the production intensity increase of construction and installation works.

Combined pneumatic cleaning and aspiration system using vortex dust collectors
Authors: Azarov A , Zhukova N , Startseva Yu 
Published: December 2019

Abstract
The article discusses the main calculating methods of the dust removal systems. Calculation and design of systems for cleaning is made taking into account the technological features of the production process and operating conditions, the typical equipment designs use and the units and machines sizes minimum number use. As a rule, the dust deposited on the ceilings of the enterprise has smaller fractions than the dust removed from the nodes of the process equipment. What is important is the parameters selection of the dust collecting apparatus for the dust to be cleaned. So, to adjust the vortex dust collectors, when using the existing aspiration systems, for the dust removal purpose, it is proposed to use a probabilistic-stochastic approach to establish fractional efficiency. The vortex dust fractional collectors’ efficiency depends on the probability of trapping dust particles of a certain diameter in the areas of installations. The procedure for determining the fractional efficiency of vortex dust collectors to adjust the stationary aspiration systems for dust removal is considered.

Authors: Sidyakin P , Belaya E , Shchitov D , Pershin I 
Published: December 2019

Abstract
The analysis and selection of the optimal finishing building materials according to the criterion of influence on the formation and propagation of acoustic resonant waves from the external sources of noise in a closed space have been carried out. The buildings located directly on the red line or at a distance of up to 100m from the roadway get most of the acoustic pressure from motor vehicles. Exceeding the permissible norms is especially often observed during the rushhours and on weekends. Acoustic waves, getting into the room and partially reflected from the enclosing structures create a resonance negatively affecting people in the room. This problem can be partially solved by the correctly-chosen home decoration materials, which have an absorption coefficient at average frequencies greater than 0.2 at geometric frequencies of 500-4000 Hz.
Problems of operating the hot water supply system during transfering the hostel to the apartment house status

Published: December 2019

Abstract
The energy infrastructure modernization is a complex social and technical problem that requires an integrated approach. After analyzing the hot water system operation in a residential apartment building, previously a hostel, the reason for the temperature regime violation was determined. In connection with the building status change the number of residents has significantly decreased, the service block has been eliminated, which led to the changes in water consumption conditions. In addition, the requirements for minimum water temperature in the centralized hot water systems have changed. The using a dead-end hot water supply system possibility question, provided for by the project or its reconstruction into the circulation network, was considered.
The studies were conducted in accordance with the methodology described in MUK4.3.2900-11 “The centralized hot water supply systems hot water temperature measurement”. There was a discrepancy in the standard indicators of the coolant temperature at the points of dismantling on different floors of the building. The difference in temperature at the input (data of the heat meter and thermometer) and at the end user is associated with additional water cooling in the supply pipes of the HWS system. When transferring public buildings to housing stock, it is necessary to revise not only water consumption volumes, but also the hot water supply scheme in general. The lack of circulation leads to hot water waste and increases the cost to the consumer.
To ensure the required temperature standards for a full day in a dead-end hot water supply system, which is provided by the project, continuous dismantling of the water is required, which is difficult to achieve with a changed building status. The resolution of the problem is possible only when the hot water supply system is switched to the circulation mode with the installation of circulation piping and the circulation pump.

Authors: Demyanov Al An , Demyanov Al Al , Pavlitskiy B I , Pavlova I V 
Published: December 2019

Abstract
The dead-end stops that prevent the descent and destruction of rail lift and transport facilities are used to ensure their safety. They are shock type, shockless type and combined. The most promising are the dead-end stops of unstressed type, since the main task of the dead-end stop is to stop the rail type device at the minimum distance. The probability of the crane overturning in the longitudinal or transverse planes of the track will depend on the "smoothness", "softness" of the braking. To improve the "smoothness" and consequently the braking safety, the dead-end stop design with the self-reinforcement effect of the resistance forces work is proposed and that can be used both for lifting and transport, and for main rail systems. Analytical dependence for the design calculation of the dead-end stop according to its main functional characteristic was obtained. The calculated dependency includes all the basic parameters allowing to determine its dimensions and configurations of the power elements and is the basis for the development of a diagrammatic layout, a general view drawing and a subsequent refined calculation of the dead-end stop design.

Abstract
Current trends of functional improvement of pneumatic car tires are described in the article. As a rule, these are the structural features of a car wheel that allow getting the nearest service station after a tire damage. The airless tire design eliminates the damages specific for pneumatic tires. They have been used for construction vehicles and military vehicles exclusively. However, improving the durability of pneumatic tires is relevant. This is due to the increase of free speed. There are two ways to improve the durability of automobile tires. The first way is to use tire damping, thanks to the new material structure of the tire. The second way is to use thermoelectric cooling to reduce thermal effects on the tire.
