Published: September 2020

This study is devoted to the architectural and artistic features of the multifunctional concert halls’ construction. Since, in our time, more and more often use non-specialized objects for the concert halls’ function (stadiums, theaters, clubs), this study is relevant. Also, the interest of researchers in the concert halls’ subject is rather mosaic and fragmented, and the works that systematically study the structures’ origin in Russian culture, from the standpoint of architectural and artistic features, are still not observed. It should be noted that the formation of a unique architecture image of a multifunctional concert hall will contribute to the tourism sector’s development, add prestige to the city and satisfy the growing demand of the population for cultural entertainment and a variety of leisure activities.

The article discusses the principles of designing the multifunctional concert halls that can be adapted to various types of concerts (philharmonic, chamber, pop, choreographic, prefabricated), due to the technical equipment that will contribute to the architectural object’s novelty. The article presents the results of studies on the conceptual model formation of a multifunctional concert hall for the city of Rostov-on-Don, which is proposed to be located on the left bank of the river Don, west of the Voroshilov bridge. This place is promising for the construction of public buildings with an entertainment function.

Features of the fine-grained concrete physical and mechanical properties and obtaining a “τ-γ” deformation curve for it based on the author’s theory
Authors: Sokolov B S , Radaikin O V
Published: September 2020

Fine-grained concrete has recently been increasingly used in practice for several reasons. The literature analysis shows that for the classes B15-B60 this type of concrete has lower values of strength characteristics and initial deformation modulus at a higher cement consumption compared to heavy-weight concrete. However, for high strength classes, fine-grained concrete has a higher compressive strength (for the class B100 - by 20.1%) than heavy-weight concrete. The model parameters’ (geometric, physical and kinematic) calculation according to the author’s theory of the anisotropic materials force resistance to compression by prof. B.S. Sokolov for heavy and fine-grained concrete of various classes - from B15 to B100. It has been established that the inclination angle of the shear sites α with increasing concrete class increases nonlinearly, and, starting from class B60, it tends to a certain constant value: for heavy-weight concrete - 73-750, and for fine-grained concrete - 67-710. For the first time on the basis of the theory, a “τ-γ” deformation curve for fine-grained concrete was obtained. It can be used in calculating bent reinforced concrete elements along an inclined section, in calculating the reinforcing bars’ anchoring length in concrete, and also in solving other practical issues.

Published: September 2020

Due to the increased level of background concentrations of pollutants in the urban air environment caused by the environmental factors and increasing annually to a greater extent due to the anthropogenic processes such as industry, transport, housing and communal services, the atmospheric air of the urban environment needs protection. One of the main environmental factors that negatively affects air, and, as a result, the environmental objects, are the solid particles (dust). The article discusses the laws of the adhesion process of the particulate matter contained in air to the buildings and structures’ vertical surfaces, which are made of various building materials. Based on the experimental studies, the regression dependencies were obtained for calculating the values of sticking and removal of solid particles on various vertical surfaces from the random determining factors. The formulas for determining the annual, seasonal, and other dust pollution of vertical surfaces made of construction and finishing materials most typical for the urban environment, are obtained; on the basis of which the methods and a program for calculating current pollution, as well as forecasting dust pollution of the buildings and structures’ vertical surfaces, located in an urban environment, have been developed. Thus, the conducted studies contribute to the solution of a number of problems related to improving the environmental safety of construction and urban economy.

Authors: Evtushenko A I , Sakharova A A , Kharlamov V O , Azarov V N
Published: September 2020

The paper discusses the physical properties of the silica clay used as building material and mineral. During crushing, pouring, packing and other processes the dust which enters the storage bunkers of dust removal systems, is formed; it is emitted from the dust collecting devices into the atmosphere, and a part of the dust enters the working area. The paper compares the elemental composition of the silica clay before the crushing operation; the dust collected in bunkers of dust removal systems; in the air emissions; the dust after using the dust collectors and working area air dust. The study was conducted using a Versa 3D Dual Beam scanning electron microscope. The dust characteristics’ comparative studies were carried out in three intake zones for three types of dust collectors used in dust removal systems: fabric filters, cyclones and swirling approach flows (SAF). The homogeneity hypothesis was tested using the Kolmogorov-Smirnov criterion. Based on the measurement results, it was concluded that the dust from the dust bunkers for all the dust collector options has a close elemental composition and can be returned to the additives’ production process. It is shown that the dust entering the working area air and in emissions into the atmosphere are close in their characteristics. The results of measuring the random distribution functions of the elemental composition and molecular weight are obtained, which allow calculating particle weight and other characteristics with 95% certainty, as well as evaluating the aerodynamic characteristics of dust particles, etc.

Authors: Epifanov R P , Shilova L A
Published: September 2020

The work is devoted to the issues related to the development of the insolation solution for the building within the construction area. It is worth noting that these aspects are regulated normatively in most of the countries. The paper presents one of the possible approaches to the development of a script that makes it possible to automate the process of developing an insolation solution for a building in the constructionarea redistribution according to the criterion of the insolation duration. The introduction of this algorithm in urban planning practice will give the architect a tool that will allow, at the initial conceptual stage of designing a new building, to find the optimal shape and location for the building from the point of view of the insolation duration, as well as to obtain a parameterized BIM model of the building, to create the apartments’ layout, providing the conditions comfortable for the people to live, or during the additional calculations of the “passive house” project development. At the same time, there is a significant reduction in time and labor costs.

A numerical experiment was conducted to study the effect on the restrictions’ cylindrical supports design strength on the crack opening and ultimate strains’ width. The analysis of the effect on the cylindrical supports’ fracture toughness and deformability of the relationship between the prestressed and total reinforcement areas (Asp/As,tot). The research results showed that the dependence of the crack opening width on the ratio Asp/As,tot for all cylindrical racks types is close to linear. The reinforcement coefficient s, tot % does not affect the nature of this relationship. The increase in the torque proportion from the vertical loads Mv/M leads to a significant increase in the crack opening width. The greatest influence on the cylindrical racks’ deflections has the prestressed reinforcement content (Asp/As,tot). In this case, the total reinforcement coefficient practically does not affect the type of function fpr=f(Asp/As,tot).

Geotechnical solutions for high-rise construction in the areas with significant elevation
Authors: Marinichev M B
Published: September 2020

The high attractiveness of the Black Sea coast in the Russian Federation, the ongoing work to create a world-class resort infrastructure lead to the need for the high-rise buildings’ construction and other heavy structures on steep grades that characterize most of the coastal strip. In such cases, they try to find the solutions that do not lead to a significant amount of earthwork when deepening the required number of floors under the stain of a high-rise building. However, with a large steepness of the relief, the excavation volume is always significant. Excavation during the engineering preparation of the territory and the development of deep pits leads to a loss of the slopes’ stability and, consequently, to the complex foundations’ solutions, engineering protection and overhead structures.

The common data environment features from the building life cycle perspective
Authors: Losev K Yu
Published: September 2020

One of the conditions for informational support of the construction projects’ life cycle and, in particular, the capital construction projects is the organization of a common data environment or, as it is called abroad, the Common Data Environment. The common data environment, being an integral part of information modeling technologies in construction, is multilevel in nature. The article draws attention to the fact that the aforementioned research object at present is considered mainly from the standpoint of foreign national standards in the field of information modeling in construction, which considers the common data environment mainly at the level of electronic document management in daily work in the design and operation of buildings and structures. Modern domestic technologies for the organization of construction should necessarily consider buildings and structures in the context of their life cycle, and not the life path, as a sequential set of data state phases. This article discusses the common data environment features from the perspective of managing the buildings’ life cycle. Using the analytical method of similarity and the dialectical method to describe the qualitative change in the model at a new consideration level, it is hypothesized that when moving from the considering interactions within the life cycle stage to the level of interactions between the life cycle stages, the concept of “data” gives a way to the “knowledge” concept. And in order to provide a complete ontology of the buildings and structures’ “life cycle” concept, a model using knowledge share is proposed.
Loads acting on the equipment’s destructive elements for removing the reinforced concrete piles’ ends

Cutting off the reinforced concrete piles’ column heads is an important technological operation in the pile foundation construction. High-quality reinforced concrete piles column heads cutting should be performed at a given mark, without cracking concrete below the cut level. At the same time, reinforcing rods of the pile together with concrete are not removed. The rational equipment design for cutting the reinforced concrete piles’ column heads is complicated by the lack of information on the required forces developing on the working body of the machine. The theoretical justification of these forces is not possible, due to the lack of appropriate guidelines. To this end, the article presents the experimental studies’ results to determine the loads on cutting elements when cutting a reinforced concrete pile of square cross section. The experimental work technique is described, the conclusions of the study are presented.
