Published: April 2021

Abstract
Security of the subject of critical information infrastructure (SCII) is one of the key issues of our time at the international level. One of the guarantors of stability and information security of society and the state as a whole is the reliability of the SCII functioning. The currently existing methods and models for assessing reliability, as applied to CII, are considered without taking into account the factor of influence of the offender, which can have a destructive effect on the subject of CII. This leads to significant errors in the analysis of the information security of the subject of CII, therefore, reduces the effectiveness of the information protection means declared for CII objects.
The proposed logical-probabilistic model is associated with the use of the specifics of the regulatory and legal framework in the field of SCII safety; structured detailing of the CII subject, taking into account the specifics of the subject; stages of the life cycle of the SCII information protection system; highlighted destructive malicious influences of an infrastructural nature; interrelationships of the selected destructs with a number of vulnerabilities on CII objects. The model takes into account physical, physicochemical, chemical, biological, operational factors of threat realization as factors affecting the decrease in the reliability of the functioning of the CII subject. The assessment of reliability indicators is carried out taking into account the characteristics of recoverable and non-recoverable objects, backup methods. The model allows you to assess the reliability of the subject of CII as an integrative characteristic, which is an indicator of the assessment of information security.

Authors: Antonenko J S , Zhdanova N S , Mishukovskaya J I 
Published: April 2021

Abstract
The article considers the experience of studying the design capabilities of unconventional materials in the design process of children’s furniture. Polycarbonate has been known for a long time, it is produced industrially and is mainly used in construction. It has good consumer and aesthetic qualities, high ductility, and relative cheapness. All this prompted a team of teachers and students to experiment in studying the possibilities of using polycarbonate in furniture for children. Children are very active and “destructive” in their activities. Not all furniture objects can withstand such loads, and those that withstand are often very expensive, because for children’s institutions furniture is needed that would be durable and relatively cheap. The purpose of the experimental work is the design of children’s furniture, taking into account the capabilities of non-traditional material, which meets the complex of modern requirements. The experimental work was carried out in three stages, on the first - the test material was corrugated cardboard, on the second - polystyrene, and on the third - polycarbonate. At each stage, a prototype was made and tested in a child care facility through operation for one month. Of the three materials studied, polycarbonate gave the best performance, which withstood all the mechanical loads of operation, retained its original shape, structural strength and external aesthetic appeal. The reviews of educators and employees of childcare facilities testify to the above qualities of the material and products made from it.

Abstract
The article considers the experience of studying the design capabilities of colored plastic in the process of designing furniture for pool locker rooms. Colored plastic is one of the most popular materials - it is a modern, environmentally friendly, and characterized by high impact resistance, resistance to abrasion, and the action of hot and detergent materials. Furniture made of plastic is inexpensive, lightweight and easy to carry; it is stabile, it is resistant to rotting processes, insects and fungi. It is not able to swell or deform under the influence of moisture. Such furniture is easy to care for. Furniture for children is often made of plastic, because it is characterized by low weight and the absence of sharp corners. Due to this, the risk of injury by contact with it is significantly reduced. These advantages have stimulated us to find ways to expand the scope of use of plastic and furniture made of it. A visit to the pool prompted us to use this material for designing furniture for locker rooms for mothers and babies, because it is plastic that is the most suitable option for this subject - spatial environment. A team of teachers and students conducted experimental work to study the possibilities of using colored plastic in furniture for pool locker rooms. The purpose of the experimental work is to design a set of colored plastic furniture for changing the pool to increase the comfortable stay of mother and baby. The development was carried out taking into account the capabilities of the material to create a convenient, safe undressing zone. The study showed that the existing furniture filling of the locker rooms of the pool for mothers with an infant is not fully equipped or does not meet the important requirements for furniture. The experimental work was carried out in three stages, at the first - a sociological study was carried out, at the second - functional ergonomic research, design features and furniture requirements and criteria for evaluating equipment for pools were determined, and on the third - a design proposal for a pool furniture set made of colored plastic was developed. Reviews of employees, managers and visitors to the pools indicate the need for this kit in modern pools in Russia.

Abstract
An attempt to systematize the experience of creating a barrier – free environment in Samara, one of the megacities in Russia, has made. In the course of work, field surveys carried out. The following priority areas for the implementation of universal design methods identified: housing, social infrastructure and a set of elements of urban utilities. In them, the consumer properties of buildings and territories have a decisive influence on the overall assessment of the quality of the urban environment. The examples are given and the difficulties of creating a barrier-free environment in new residential compounds and universities, as well as in the objects of the municipal sphere of the city analyzed. The conclusion that the process of introducing the principles of formation of a barrier-free environment has a rather low pace has made. This is not in line with the city’s sustainable development objectives. The question of the development of local urban planning regulations and design standards, which will allow the transition to the massive use of the principles of universal design, has raised.

Published: April 2021

Abstract
The use of dispersed reinforcement improves the properties of concrete. Recently, some studies have been conducted to explore the effect of dispersed reinforcement on the behavior of structures under a static load of the same sign or alternating static load when reinforcing with relatively long fibers.
The article presents a methodology for experimental study of the behavior of beam elements with dispersed and combined reinforcement under an alternating static load, based on mathematical planning using a specially made frame.
The work considers the results of experimental studies of cubes and prisms on a static load and compression. It also presents the results of an experimental study of the behavior of beam structures with dispersed and combined reinforcement with relatively short fibers under low-cycle alternating static action. The behavior of fiber-reinforced concrete and reinforced concrete beam elements under similar influences are compared.
The presented results of the experimental studies allow us to show a significant effect of dispersed reinforcement with relatively short fibers on the behavior of beam structures with alternating low-cycle static loads and the feasibility of combined reinforcement of structures operating under such loads.
The use of dispersed reinforcement with relatively short fibers in combined reinforced beam structures operating under alternating loads will increase crack resistance, and with a certain percentage of reinforcement, the strength of such structures. Moreover, the use of relatively short fibers will significantly reduce the complexity of manufacturing such structures.

Reconstruction of Industrial Residential Buildings Built in the 1950s–1970s with Application of Modern Wooden Structures
Authors: Podshivalov M E , Aksenova I V 
Published: April 2021

Abstract
A substantial part of the dwelling stock in the Russian cities and towns was built in the period of 1960s and 1970s. In the circumstances of the deficient territorial resources in many cities, the need to renovate the post-war residential constructions of the initial period in the industrial construction of dwelling houses is considered as one of the major vectors in providing the dwelling facilities for the citizens. Basing on the analysis of the modern methods, the authors draw the conclusion that the possibility to realize the renovation programs is available only in the capital cities, where the land is highly attractive in terms of investments. As far as regions are concerned, it would be more adaptive and more beneficial to choose the option of the comprehensive reconstruction. The authors also considered such question as whether it would make sense to proliferate the international experience of applying the new technologies and the modern wood-based structures in reconstruction of buildings. This measure would make it possible to resolve not only the practical, but as well the ecological and architectural plus esthetic tasks in renovation of the existing standard buildings, to raise the status and profitability of the standard dwelling buildings and to reduce the ultimate cost of the reconstruction. Basing on the conceptual project for renovation of a mini-district in the central part of Irkutsk, the authors have demonstrated the possibilities of reconstructing the dwelling quarters with the use of modern technologies for the wooden housing construction.

Published: April 2021

Abstract
The article raises the problem of implementing the principles of the Venice Charter in the practice of restoring architectural monuments that have suffered as a result of natural disasters and human activities. The carried out restorations of various types of monuments of public architecture were considered. The principles that guided the authors of the restoration project, as well as external circumstances that influenced the course of restoration work, were analyzed. Conclusions were drawn about a significant deviation from the principles of the Venice Charter in practice: holistic restorations predominate with the preservation of the familiar appearance, the use of materials that do not differ from the original, the reconstruction of not only facades, but also interiors of architectural monuments in their previous forms.

Published: April 2021

Abstract
The paper deals with the main principles of foam polyethylene production by the addition of recycled polyethylene and a modifier in the initial mixture. Obtaining of the modified foam polyethylene will accomplish two important tasks: solve the environmental problem of recycling polyethylene waste and reduce the cost of the material. The optimal consumptions of recycled polyethylene and a modifier were determined by using the methods of mathematical experiment planning. To predict the main characteristics of the modified foam polyethylene a special nomogram was worked out. The properties of the developed material were studied. Based on the obtained results, it was found that the modified foam polyethylene had quite proper physical and mechanical characteristics and could be recommended for use in insulation systems of frameless and frame buildings, as well as in floating floor systems.

Published: April 2021

Abstract
The process of forming new technological methods of construction of buildings and structures, a high degree of industrialization of construction and unification of elements, lead to the study of various principles of forming the spatial structure of the object from flat scans. The authors consider a new transformable architectural and structural system consisting of rod spatial arches, the main elements of the developed system are rods and hinges that connect them at the ends. The latter are made as an analog of bionic mobile communication. Analysis of the transformation of a rod spatial element into an arch of various shapes is performed by the following methods: traverses, jacks, pneumatic structures and automatic methods. As a result, you can use rod arches to create buildings and structures of various shapes. In the end, the versatility of such spaces allows buildings and structures based on rod spatial arches to be multifunctional. Specifically for the arches of the NPI series, the authors developed a hinge Assembly designed to connect the rods of a fast-erecting light spatial structure of a regular structure. Research has shown that on the basis of the resulting arched strezhnevoy system, it is possible to form spaces close to the cylindrical and spherical shape. The variability of forms based on a single set of structures, low-labor-intensive installation process using the principles of self-construction, create prerequisites for new research in the field of improving this type of transformable architectural and structural systems. These issues provide a wide range of tools for solving architectural, structural and technological factors of shaping, which contributes to the development of creative activity.
Efficient Volume Modules of Polydispersion Composites with Spherical Inclusion
Authors: Erofeev V T , Tyuryahin A S , Tyuryahina T P , Tingaev A V 
Published: April 2021

Abstract
The formula of R. M. Christensen [14], according to the definition of the volume modulus of polydisperse composites with spherical inclusion, is transformed to the dimensionless function k = k (η, θ, w) of these modules, which depends only on three dimensionless parameters. For a given value of the parameters η and θ, the modulus formula becomes a function of k = k (w) of one argument (volume fraction of inclusion). In a flat space k - w, the function k = k (w) is mapped by a curved segment between the points (0, 1) and (1, 0) of the same space. For different values of η, the function k = k (w) displays the spectrum of curved segments between the points mentioned above. This spectrum determines the position of a plane figure in the space k - w. The shape of the figure and its position (in this space) changes with other values of the parameter θ. Examples are given of constructing two similar figures for characteristic subsets of the values of the function k = k (η, θ, w).
Limiting Pressure on Sandy Foundations of Pavements
Authors: Kalinin A L , Martyniuk E V , Kuzin N V 
Published: April 2021

Abstract
The purpose of the article is to determine the limit value of pressure on the sandy foundation of pavement. Such pressure is understood as the first critical load on the soil, which separates the stages of linear and nonlinear deformation of the base. The method of experimental research is testing the base with a hard round stamp. The stamp load was applied in steps, and its value increased until a nonlinear dependence of the shrink from pressure appeared. The tests were performed on a built sandy foundation of pavement on the street Donetskaya in the city of Omsk. For the experiment, 15 points were chosen at which was installed the stamp and loaded with measurement of load and shrink. The test results are processed by methods of mathematical statistics with a reliability of 95%. As a result, a confidence interval is established within which the true value of the limiting pressure on the sand base varies. The value of limiting pressure can be used when designing pavements as a value that limits pressure on the sand base and eliminates shear deformation of the sand.
