Published: September 2020

Abstract
The article analyzes the formation of the modern ethnic design structure under the influence of certain ethno-cultural components. The ethnic direction development in contemporary environmental design is considered as an indicator of the various cultural zones’ uniqueness preservation, with the subcultural identity components’ inclusion in its structure, which allow preserving individuality in the cultural globalization space.
The creative environment of ethno-design contributed to the definition of the traditional “pole architecture” of nomads as a creative source for the Lagan tourist base design during the pre-project analysis. Based on the example of our own design - project, design means analysis of the ethnic design structure’s components.
The article provides a comparative analysis of this area development in the Russian practice of environmental design. The article defines Russian ethno-design as a new scientific direction, examines the fundamental principles of designing regional cultural and tourist sites of ethno-design in the unique ethnic traditions’ context. The formation of ethnic design structure under the influence of nomadic architecture traditions is analyzed. The creative position of ethnic design in the world today is determined by transforming the cultural images of the past in a new context. The importance of ethnic design in shaping the region’s image for ethno-tourism is considered.

Published: September 2020

Abstract
Under the influence of global, including the innovative processes in order to free land for the new objects’ construction the unique examples of immovable cultural heritage are destroyed, which radically changes the appearance of the historical environment. At the same time, against this background, interest in ethnography, the architectural monuments and the samples of folk architecture of different eras has increased. In addition to the aesthetic qualities proper, the objects of historical and cultural heritage embody interesting, specific historical and memorial events of previous centuries. Ethnographic parks are an effective form for preserving and presenting historical and cultural material heritage, as well as for demonstrating the unique natural landscapes by including their individual fragments in the ethnographic parks’ structure. Despite the huge volume of immovable heritage, architectural monuments of various eras and unique natural landscapes of various regions, in Armenia there are no ensemble and environmental ethnographic parks. The article discusses the architectural problems of creating ethnographic parks on the basis of a scientific approach to the study of their nomenclature, structure, functional orientation, territories’ zoning, placement in the planning framework of the region, city, exposition. The problem of the ethnographic parks’ architectural and spatial organization is studied taking into account the historical development specifics and the climatic features of Armenia. Based on the analysis, a number of recommendations are made.

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

Abstract
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

Abstract
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.

The study of the silica clay dust elemental composition in building materials’ production
Authors: Evtushenko A I , Sakharova A A , Kharlamov V O , Azarov V N 
Published: September 2020

Abstract
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: Shalenny V T , Andronov A V 
Published: September 2020

Abstract
The research discusses the ways to ensure the construction and operation reliability of the designed buildings and structures in earthquake-prone areas, which include the Republic of Crimea. Substantiated techniques for improving the installation structures’ technology of kinematic insulation systems developed and tested in the Krasnodar Territory of the Russian Federation are shown. The improvement consists of the innovative three-stage method of installation and alignment of concrete pipes, including successive concreting of foundations, assembly, alignment and pouring in the lower part of the column, and finally after maturing, non-alignment assembly of the middle and upper parts of the column. To reduce the intensity of inertial seismic loads, the use of precast-monolithic ceilings from hollow-core pinched reinforced concrete slabs or monolithic slabs with plastic inserts partially replacing reinforced concrete is justified. Improved designs of such plates are presented; their effectiveness and rational application are evaluated. Taking into account the preferable long periods of the insulation systems and foam glass-based finishing maintenance-free operation, their improved structural and technological solutions are presented as a part of earthquake-resistant wall filling of frame buildings.

Published: September 2020

Abstract
The article is devoted to the stress-strain state of multilayer beams’ study of the. The beam model is represented by the main and connecting layers. For the main layers, the classical Euler-Bernoulli hypotheses are used. The contact layer model is used to describe the connecting layers. As a result, a system of resolving equations for solving numerous problems is obtained. As an example, the analytical solution to the problem of bending a two-layer beam is given. The resulting solution describes the stress-strain state of the beam in the range from the ideal contact of the main layers to the complete absence of the contact. It is shown that the used model of the contact layer allows satisfying all the boundary conditions, including the fact that the tangent stresses at corner points are equal to zero. The influence of the contact layer’s stiffness on the model’s stress-strain state is analyzed.

Published: September 2020

Abstract
The paper presents an effective scheme for studying the direct and inverse problems of identifying the delamination of the elastic layer from the base. The proposed approach is based on the problem’s asymptotic analysis, based on the assumption that the relative size of the defect is small. In the framework of the asymptotic approach, the transcendental equations for reconstructing the bundle parameters are obtained. Identification is carried out using the additional information about the amplitude values of the displacement field measured at the upper boundary of the layer. The numerical results of the restoration are presented.

Boundary rod elements for modeling the railway at the bridge crossing under the action of the speed railway load
Authors: Ivanchenko I I 
Published: September 2020

Abstract
New rod boundary elements on an elastic foundation (finite elements of large length, when approximating the displacements by a set of linear and trigonometric functions) are proposed for calculating the path oscillations outside the bridge and on the bridge, combined with a double-track beam bridge connected through a layer with a high-speed rolling stock movement. The selection of interlayer material is related to the dynamics of the bridge. To build the methodology, the articles published earlier by the author are used: a step-by-step procedure for solving the problems of unsteady dynamics of structures and the method of “nodal accelerations” to take into account the action on the structures of a moving inertial load.

Authors: Klochkov Yu V , Vakhnina O V , Sobolevskaya T A , Klochkov M Yu 
Published: September 2020

Abstract
The technique of forming a stiffness matrix of a volume prismatic finite element with a triangular base and with six nodes located at the vertices of the prism is presented. The discretization element is formed on the basis of the interpolation procedure vector form with consideration as the interpolation object of the displacement vector of an arbitrary point of the engineering structure. It is proposed to improve the compatibility of the prismatic discretization element at the boundaries of the docking of the bases by using Lagrange multipliers as additional nodal unknowns, which are introduced in additional nodes located in the middle of the prismatic discretization element bases’ sides. The presented vector form of interpolation allows one to obtain the correct finite element solutions in the problems of determining the stress-strain state of engineering structures using curvilinear coordinate systems.
