Deflection of beams with sinusoidal perforation
Authors: Pritykin A I 
Published: September 2020

Abstract
The presence of cutouts in the beams’ walls made of steel or from modern composite materials reduces their shear stiffness and increases deflections in comparison with beams of the same size with a solid wall. In this paper, we study the deflections of perforated beams with a sinusoidal shape of cutouts, which are widely used in construction recently. The cutouts’ effect on the perforated beams’ transverse bending was investigated analytically using the theory of composite bars and the finite element method. The aim of this work was to obtain an analytical dependence that allows to reliably evaluate the deformations of the beams with hexagonal cutouts with different angles of rounding. The study was conducted for the beams of different sizes, made by the non-waste technology from a rolling profile. An analysis of the calculating results for the beams made of different materials showed that with a decrease in the material elasticity modulus, the deflections of the beams increase, and a change in the yield strength of the material does not affect the deformation characteristics. The obtained dependence is applicable for the beams with a relative length l/H ≥ 10 at a relative cutouts’ height h / H = 0.667 The discrepancies with FEM results do not exceed 1.5-3%.

Authors: Tkachenko A V , Yudina I M 
Published: September 2020

Abstract
The article solves the problem of the stress state of a heavy half-plane, weakened by a semicircular recess (modeling a foundation pit) and under the influence of a uniformly distributed load (modeling weight from a nearby building). The solution was obtained in a closed form. Visual calculations results in the form of diagrams and isolines of the total voltage are presented. The resulting solution made it possible to consider two practical problems. In the first statement, to assess the pit parameters’ influence on the components of the additional voltage in the corner zone of the distributed load. In the second statement, to assess the distance influence from the pit to the load on the additional voltage components. The analysis of the obtained solutions is carried out. The quantitative character of the change in the additional stress components, on which the dimensions of the influence zone of the construction pit and the existing buildings foundations’ deformation is of particular practical interest.

Authors: Diakov I N , Tsarenko N V , Diakov M I 
Published: September 2020

Abstract
The experimental studies’ results of the foundations with a soil base interaction are presented. The relevance of the research is associated with increased accidents of buildings and structures in recent decades. The reasons for the occurrence and features of sudden foundations loading are considered. The experimental research methodology, the characteristic models of foundations are presented. The preliminary experimental studies’ results of the foundations with sudden loading are presented and analyzed. Some features of the “foundation-soil” system are determined. A decrease in the bearing capacity of the foundations during sudden loading, depending on the level and prestressing type, was revealed. It is established that the main reason for the decrease in the foundations’ bearing capacity is a change in the normal contact stresses diagram. The necessity and directions of further research in this area are substantiated.
Complex model of fractal architecture building
Authors: Kravchenko G M , Pudanova L I 
Published: September 2020

Abstract
The fractal structures paradigm is applicable for creating the complex architectural objects. Using special programs, it is possible to implement a comprehensive model of the fractal architecture building as a structure consisting of an endostructure and an exostructure. During the study, the first two iterations of the endostructure on the possibility of using such structures’ element as a supporting skeleton of a fractal architecture building were considered. The endostructure elements of the first iteration strengthen the exobase and the lower surface of the f-quarks of the exostructure. The endostructure of the second iteration is much more complex and voluminous than the structure of the first iteration and strengthens the upper part of the exostructure. To ensure the stability of the fractal architecture building, the framework is formed by connecting the elements of the endostructures of the first and second iteration. Based on the fractal structures’ formation analysis results, the unique building stiffness cores formed from the f-quarks exobase have been developed. The strength and rigidity of the building is ensured by the combined action of the endostructure’s elements, the exostructure’s elements and the developed stiffness cores. Comprehensive building model was implemented in ANSYS PC. According to the numerical experiments’ results, the maximum displacements, shapes and frequencies of the fractal architecture object’s natural vibrations are determined. The proposed design solutions for a complex model of a building based on a fractal structure are unique and require the use of innovative technologies and materials.

Published: September 2020

Abstract
The purpose of the article is to consider and analyze the stylistic features of neoclassicism, manifested in the architecture of the Lower Don cities in the early twentieth century. To achieve this goal, literary sources were studied and a visual analysis of the architectural objects of the period under consideration was carried out. The article describes the factors that influenced the formation of neoclassical trends in the Don region in connection with the general dynamics of the architectural development and the peculiarities of its socio-economic and cultural situation at the time. The interrelation of various conditions that affect the choice of options for volumetric, spatial and artistic solutions of architectural monuments of the first two decades of the twentieth century is analyzed depending on their purpose and the general urban situation. The analysis of the used stylistic means and plastic features of the Don region the most significant architectural structures appearance related to pre-revolutionary neoclassicism was carried out. In the final part of the article, the conclusions regarding the regional architecture neoclassical monuments’ features in comparison with the capital’s architectural structures of this period are drawn. In particular, it is noted that, unlike many metropolitan architectural designs, in the buildings built during this period in the cities of the Don Territory, a mixture of stylistic means is often observed due to the regional specifics. The modern look of the Don region cities (primarily their historical part) is largely determined by the neoclassical architecture monuments, and the consideration of their features is necessary when developing the new architectural solutions designed to ensure the comfort for the urban environment.

Authors: Tsanaeva E A , Molchanova K E , Irmanova E V 
Published: September 2020

Abstract
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.

The preserved wall painting dates from the turn of the 19th and 20th centuries. The state of monumental painting, the determination of its preservation degree, the development of methods for its restoration, including disclosure from marks, strengthening, tinting, and making up for losses, are examined. In order to develop the proposals for restoration, a study of its fragments was carried out by the X-ray phase analysis on an “ARLX’TRA” diffractometer to determine the composition of plaster, soil and paint coat. As a result of the analysis, it was established that wall paintings are oil painting on gypsum soil. Based on the studies, it is proposed to carry out the following works: cleaning from whitewash, removing the surface contaminants, strengthening the paint layer.
The place history reading in the image of the urban areas’ formed public space
Authors: Vorobeva A M 
Published: September 2020

Abstract
Modern urban development policy in our country is currently consonant with the trends in environmental decisions of the European countries, namely, a wider landscape approach in the practice of designing and building the urban entities, called “landscape urbanism”. Formation of landscape objects with different “themes” in city centers and individual areas, reflecting the history of the place or a certain historical style inherent in the surrounding buildings, allows not only to create a better environment for permanent residents or visiting tourists, but also to turn these landscape objects into a city attraction. They become unique for the citywide territories.

Published: September 2020

Abstract
The restoration of the “brick facades” of historical objects is a fairly studied task. A large number of materials and technologies are used in its solution today, however, their application does not always lead to the excellent results. The purpose of this study is a comparative analysis of the effectiveness of the materials used and the methods of repair and restoration work with brick materials, depending on the monument’s initial condition, its utilitarian use and the architectural stylization of its facades. This article compares and discusses three methods of repair and restoration of the historical objects’ “brick facades”: the “traditional” method of brickwork restoration, used mainly in the monuments’ restoration experience in Russia; materials and technologies of Caparol company (Germany), as well as the materials and methods of repair and restoration of the brick facades in the Remmers company (Germany). The analysis objects are the history and architecture monuments of a number of South Russian cities; the period of repair and restoration of these facilities from 2013 to 2020 The effectiveness of the indicated methods and materials’ application at the stage is compared: preparatory work, repair and restoration of lost masonry, restoration of masonry with reprofiling; and at the stage of the facades’ finishing. The results of the combined use of various methods are presented. The presented observations and conclusions on the practical conduct of repair and restoration work using various materials and technologies on a number of architectural monuments made in the “brick style” are “equipped” with the data for effective planning and development of “optimal” technological maps for the future restoration objects.
