Published: March 2020

Abstract
Establishment of the valid technical condition, research of relationship of cause and effect and hierarchy of the factors influencing use reliability of load-carrying structures of town-planning objects of industrial function at their reconstruction and reprofiling is the main objective of safe and reliable operation. By method of the atomic and emission spectral analysis it is established that separate elements of farms are made of the “boiling” steel that does not conform to requirements of existing rules. Values of movements, efforts on combinations of loads by snow load and ranges of distribution of potential energy of deformation on farm elements are received. The analysis of intense state of strain of roof frames of covering of the inspected industrial buildings has shown that their bearing capacity in zone of possible formation of snow “bag” from height difference and extension to workshop of higher flight is not sufficient. By results of the conducted researches recommendations for safe further operation of roof frames of covering and valid conclusion about degree of their suitability for the planned conversion and modernization of industrial buildings are formulated.

Published: March 2020

Abstract
The paper presents the results of experimental research on establishing the possibility of using furnace gasses and sodium manufacturing waste as low-activity lime dust in the solid building materials manufacturing technology. Research on the changes of physical and mechanical properties and structure of the material based on lime-calcareous compositions that solidify in the environment with increased carbon dioxide concentration after being stored in the natural environment for 24 months were conducted. Material samples constitute semidry-pressed cylinders (compacting pressure – 30 MPa), made of a mixture of low-activity lime dust and a filler, which is waste material from extraction of limestone of Crimean deposit. Conducted research of physical and mechanical properties, of structure and characteristics of material’s porosity had shown that an increase of samples’ strength could be observed both as a result of portlandite changing into calcite upon forced carbonation, as well as a result of repeated crystallization of scalenohedral calcite into rhombohedral shape after storing samples in the natural environment.

With the advent of modern public space, formed around heritage sites, residents of the city are aware of their cultural and historical value. At the same time, entrepreneurs will be convinced of the possibility of commercialization of historical heritage, observing its connection with pedestrian flows and turnover of enterprises, and will be involved in the process of developing rules for organizing and using city streets. The preservation and return to the economic turnover of heritage will not be imposed, but an internal goal, shared by economically active, significantly influencing the decision-making, actors of the urban community.
Using Free Lidar Data with Aerial Photogrammery Images for Construction of 3D Building Models for Openstreetmap
Authors: Youssef A , Prisyazhnuk S , Petrov A , Atlasov R 
Published: March 2020

Abstract
3D-modeling of buildings in OpenStreetMap project (OSM) is a new trend, and the level of detail (LOD) for most 3D building models still present - LOD1 without taking into account the modeling of building roofs. In addition, there are many defects and shortcomings existing in 3D building models that need to be corrected and adjusted. In this article, we propose to use the available data LiDAR (Technology of using light in the form of a pulsed laser to measure distances to objects on Earth) with free aerial photography image to build 3D models of buildings to eliminate existing defects and shortcomings and to obtain fairly accurate 3D building models for OSM. To demonstrate one of the shortcomings of 3D OSM models, we reviewed the 3D model of the building of the St. Petersburg National Research University of Information Technologies, Mechanics and Optics (ITMO) in OpenStreetMap, and, having corrected this deficiency, obtained a revised 3D model. Applying the proposed method of using LiDAR data with aerial photography, we selected a territory in the city of Christchurch in New Zealand, where there are available LiDAR data, downloaded LiDAR data point clouds from the Open Topography site and built fairly accurate 3D models of buildings that exist in this area of study with their roofs using the Global Mapper software. Accordingly, we received good and complete 3D- building models with a level of detail LOD2.
A New Fire-Resistance Test Method for a Reinforced Concrete Truss
Authors: Ilyin N A , Panfilov D A 
Published: March 2020

Abstract
An innovative technology relates to the field of buildings and structures fire safety (hereinafter Buildings). In particular, we can use this technology to classify reinforced concrete trusses according to their resistance to fire. This provides an opportunity to reasonably use trusses with actual fire-resistance of buildings with various fire hazard classes. A summary of the innovative technology is to test tensile and compressive elements of a reinforced concrete truss under fire conditions without destruction according to a set of simple quality factors. The resistance procedure of load-carrying elements of the reinforced concrete truss to standard fire exposure is represented by mathematical dependences that take into account the integral heat engineering and design parameters, as well as the features of tensile and compressive elements reinforcement. The new method application makes it possible to determine the actual fire-resistance of tensile and compressive elements of the reinforced concrete truss without actual heat exposure; increases the reliability of non-destructive tests; makes test conditions of tensile and compressive elements closer to the actual operating conditions. The fire-resistance of the reinforced concrete truss determines the resistance limit to fire exposure of the weakest element.

Study of Air Quality in the Office Building
Authors: Agafonova V V 
Published: March 2020

Abstract
This paper is devoted to assessment of air quality in an office space of a public building. Analysis of the results of researches made in this area by Russian and foreign authors showed that state of human health deteriorates at CO2 concentration level of 600-800 ppm and more and this can lead to decrease in performance and increased fatigue of office workers. Long-term human exposure to carbon dioxide can lead to chronic diseases. Results of experimental study of changes in carbon dioxide concentration in 30 m2 office space of a public building when 5 people are continually present in the office are given in this paper. CO2 concentration measurement was carried out during 24 hour period using MT 8057 portable carbon dioxide detector. According to the measurements results, a graph of CO2 concentration changes versus time was drawn. Conclusion that, in some periods of working day, air quality was unsatisfactory (from 10:40 to 13:30 and from 14:45 to 19:00: CO2 concentration exceeded 1000 ppm) indicates insufficiency of existing ventilation system and excessive room sealing (due to application of plastic windows). There is a need in technical solutions to improve efficiency of supply and exhaust ventilation.

Published: March 2020

Abstract
The theory sound insulation based on the matching of the wave fields by M. S. Sedov and Statistical energy analysis (SEA) are used to model sound transmission through single and double leaf partitions. A fragment of a building is considered as a set of acoustically connected rooms and structures. On the basis of the method of statistical energy analysis, the equations of energy balance are written, the solution of which allows to determine the energy of sound in the rooms and the energy of sound vibration in the structures. A complete model of the SEA, including bending, longitudinal and shear waves in structures and sound waves in the air volumes of the rooms, is proposed. The coupling loss factors from room to room (non-resonant sound transmission through partitions) are calculated on the theory by M. S. Sedov. It is given the calculation of the coupling loss factors, internal losses and modal densities. The results of vibro-acoustic calculations and measurements on models of the building fragments are presents.

Composite Binders for Fastening High Temperature Wells
Authors: Krivoborodov Y , Samchenko S 
Published: March 2020

Abstract
The article deals with the hydration of oil-well cement, intended for cementing high-temperature wells. At high temperatures and pressures (150°C, P = 30 MPa) Portland cement stone does not have the necessary density and resistance to high temperatures due to the formation of hydrated calcium silicates rich in lime during the hydration of Portland cement, therefore, the work was carried out primarily to find appropriate additives to Portland cement, providing the necessary properties of oil-well cement. From a number of additives to ensure the durability of service were selected reprocessing waste of titanium ores (titanomagnetite concentrate) and blast furnace slag. In addition, to improve the crack resistance of cement stone, the possibility of using expansive additives to oil-well cement was investigated. For these purposes, sulfoaluminate, sulfoferrite clinkers and alumina slag were used.
It has been established that during hydration of calcium sulfoferrite ferrous ettringite is formed, which is more stable at elevated temperatures than ettringite formed at hydration of sulfoaluminate clinker and alumina slag. In the presence of sulfated phases and silica, at elevated temperatures and pressures, low-base calcium silicates hydrates and iron contained garnet hydrates are formed.

Abstract
One of the problems of modern road traffic is the problem of icing roads in the winter time, because of this problem the number of road accidents is growing. With this problem every year massively fighting, using different chemical compositions. In addition to this problem, there is also a problem associated with the use of heat supply systems. It consists in the presence of heat energy losses during the delivery of hot water from the heat production site to the heat consumption site. It is also fought, using new thermal insulation materials. All methods of solving both of the above problems are effective for solving these problems in particular, but they cannot be taken to solve them together. For this reason, there is a need to create a method capable of dealing with these problems together. In this article the method allowing to fight against icing of the road by means of increase of temperature of asphalt, using sites of transportation of thermal energy to the consumer will be considered.

Published: March 2020

Abstract
The article presents an algorithm for restoration of the original data table using GRNN artificial neural network and the results of the algorithm in testing and empirical data. The given article also deals with calculations of the relative error for different data types with different percentages of passes. The quality of the analyzed data resulting from the passive experiment, as well as the reliability of the analysis results depends on one of the most important factors: the presence of these missing values. The distortion of the original data or incompleteness may distort the result in the general modeling process. Gaps in the original data table may be associated with a complete lack of data (raw data incompleteness) and contradictions arising from the data. And this kind of problem can occur not only with the values of a single attribute, but also with the values of a certain set of attributes especially in those cases when it comes to the large dimension of the factor space.
