Published: March 2020

Abstract
The existing state of the Far Eastern sea cities’ public spaces is characterized by shortcomings and contradictions. Further development of coastal cities requires the development of a scientifically based methodology for the environment’s reconstruction with the aim of developing and improving of public spaces’ system. The research methodology is based on a comprehensive analysis and systematic approach to the problem of forming an effective system of public spaces in the city. An integrated approach provides an effective social and functional reorganization and architectural and artistic improvement of the city’s public space system. The conducted studies allow us to formulate the main directions and principles of the existing system of the Far Eastern sea cities’ public spaces’ reconstruction. The principles and methods formulated in the work were tested during the development of experimental projects’ series for the renovation of public spaces in the city of Vladivostok. Design developments and practical implementation have shown the effectiveness of the basic principles and methodology of the Far Eastern sea cities’ public spaces’ renovating.

Research of Socio-Spatial Aspect of Economic Security of Megacities: Risk Zones and Conflict Nodes
Authors: Orlovskaya T 
Published: March 2020

Abstract
The article deals with the approaches to the analysis and assessment of the global city conflicts, used in the world and Russian practice, which allow conducting comparative studies of local areas in megacities, identifying risk areas and nodes of conflict. The study of economic security of megacities logically justifies the consideration of “conflict nodes” as threats and risks of a certain type, as a result of the analysis of “risk zones” and the conditions of contradictions in megacities, it is possible to use the tools of operational and strategic development management to improve the image of the city, its competitiveness and attractiveness. The Authors propose to consider the theme of “conflictness” of urban space in the context of monitoring the safe development of megacities. Evaluation of the level of safety and conflict within the megacity is based on statistical data and indicators of public opinion about achieved level of security. The results of the study are the clustering of St. Petersburg districts by conflict indicators and risk zones, the evaluation of adequacy of objective indicators of security of residence in a particular area and subjective assessments of residents. The article presents the results of assessing the level of conflicts in St. Petersburg as a global city, a comparative analysis of the subjective and objective component of the socio-spatial aspect of economic security. On the example of St. Petersburg, the Authors compare the identified clusters by risk zones and conflict nodes and illustrate the obtained result.
The Concept of Socio-Spatial Development as the Basis of Economic Security of Megalopolises
Authors: Ershova S A , Orlovskaya T N 
Published: March 2020

Abstract
This paper investigates major lines of research in socioeconomic and spatial analysis of major urban centers. After thorough investigation of previous research in the fields of spatial economics, proximity analysis and using the phenomenological field concepts, authors propose to consider sociospatial development as foundation of urban economic security. In order to measure the state of urban security, authors suggest distinguishing between three phenomenological axes: axis of socioeconomic development, axis of quality of urban environment, axis of crime rates, and to use methodology of proximity analysis. Using the data on St.-Petersburg authors demonstrate degrees of proximity along distinguished axes. Comparative analysis is performed via STATISTICA packages for cluster analysis, grouping major urban centers using agglomerative cluster-method. Indicators relating to phenomenological axes are chosen as a result of previous studies analysis in the areas of quality of urban environment, urbanization rates and conflicts in major urban centers, as well as through expert evaluation of relative importance of indicators for livability provision.

Published: March 2020

Abstract
The article considers the currently relevant issue of achieving the organization of advanced development. Since, as a rule, the innovative development approach is the basis for managing the development of an organization, which suggests the implementation of projects for the development and production of advanced development in an enterprise, the focus is on assessing the organization’s innovative potential in the context of expanding the global information space. As a result of the innovation process carried out by the organization, there is not only the achievement of advanced development, but also the development of highly competitive products that form a new product market and radically change the existing market. Of course, to create a product that leads an organization to advanced development, it is necessary to have a number of resources and competencies discussed in the article. The example of the smartphone market, which characterized by a multidirectional change in the share occupied by the main manufacturers with similar innovative potential, is considered. As part of the mathematical model of Stackelberg, which describes the behavior of players in the oligopolistic market for high-tech products (as discussed in the article, the smartphone market), the game of several players-companies supplying their products to the market was considered.

Authors: Konstantinov A , Verkhovsky A 
Published: March 2020

Abstract
The analysis of negative temperatures influence on air permeability of modern PVC windows was made. For this purpose, complex tests of several types of PVC windows with different profile thicknesses were performed in the laboratory. The determination of the windows air permeability was made under standard conditions (+20 °C) and negative outside temperatures (-5°C, -15°C, -25°C, -35°C, -45°C). For the windows air permeability determination at negative outdoor temperatures was created the special test stand. It was found that at negative temperatures there is a significant decrease in the windows air permeability is observed. However, this process occurs differently for PVC windows with different profiles thickness, this process also depends on the outdoor temperature. The research results are proposed to be used to calculate the buildings heat balance. This will increase the calculations accuracy, since this will use the windows air permeability data, determined not under standard conditions (as it is now), but under real winter conditions. The further research directions of the issue are given.

Published: March 2020

Abstract
Changes in the structure of public spaces of cities are conditioned by spatial-planning, environmental, social factors and often in post-Soviet cities have spontaneous and a little controllable character. At the same time, the set methodology of urban planning cannot provide an effective tool for environment formation, fully complied with new social needs, which makes the development of principles and technologies of the transformation of environment relevant, which is capable of evolution and self-development. The particularity of construction of public spaces of the Soviet city and the features of their social and spatial transformation in the post-Soviet period are considered. Urban public spaces, being in the process of development in space and changing in time, are characterized by the properties of incompleteness and enrichment of their environment with elements of time. On this basis, the typology of public spaces is considered on the example of the territories of the Krasnoarmeysky district of Volgograd as the main semantic structure-forming elements and socially significant dominants of the city, the types of spaces are defined according to the degree of completion of the formation: emerging, habitable, stable, subject to reconstruction and possible directions of their transformation are proposed. The conclusion about the need of preservation of the specific spaces of the city, containing outstanding historical elements, and their transformation based on the principle of historical continuity, built on the combination of historical objects and new components of the environment is made.
Affecting of the Long-Term Deformation to the Stability of RC Frame-Bracing Structural Systems under Special Accidental Impacts
Authors: Fedorova N V , Savin S Yu , Kolchunov V I 
Published: March 2020

Abstract
The paper is devoted to investigation of the loading duration affecting to stability of structural elements of reinforced concrete building frames at post-critical states caused by the sudden removal of one of the load-bearing constructions. Modelling of strength and deformation characteristics of reinforced concrete under long-term loading was performed using the theory of plasticity of concrete and reinforced concrete proposed by G.A. Geniev. Following to this theory, the rheological model of long-term strength of concrete was presented by two elements connected in series, one of which characterizes the process of short-term loading, and the second viscous element corresponds to the Kelvin-Voigt model and takes into account the processes of long-term deforming. It was established that at long-term loads acting to operated reinforced concrete structural system the value of critical force corresponding to loss of stability of the structural element decreases. This fact should be taken into account when assessing the resistance of such building frames to progressive collapse under special accidental impacts caused by removal one of load-bearing elements of a structural system.

Authors: Dolinsky Y A , Starkov G B , Matveev S A 
Published: March 2020

Abstract
Three main factors were taken into account cost, quality, and time when repairing the highway R-256 “Chuysky Trakt” in the Altai Republic. Repairs were carried out using various types of road constructions using cold recycling technology, implemented both at the near-road plant and directly on the road. The four types of structures are most common. The first type is asphalt and granulated concrete with a thickness of 20 cm using a mineral binder. The second one is asphalt-granulated concrete with a thickness of 15 cm using a combined binder. The third is with the use of wear layers of bitumen-mineral mixtures and leveling layers of asphalt concrete mixtures. The fourth - with the use of a combined binder and a layer of wear from the bituminomineral mixture with the use of polymer-bitumen binders. The use of cold regeneration technology of existing pavements allowed not only to restore their bearing capacity, but also to increase it by 50% to 56%, depending on the type of pavement design used.

Published: March 2020

Abstract
The article presents the calculation of a composite reinforced concrete bridge superstructure 42 meters long and 15.9 meters clear width, taking into account the layout cross-section zero axis position correction. It is assumed to pair the concrete slab of the carriageway and the steel main beams along the neutral axis of the section, at the same time reinforced concrete will perceive only compressive forces, and the steel main beams will perceive only tensile forces. Steel beam and reinforced concrete slab are included in the work at the same time and together perceive internal forces from permanent and temporary loads. The bridge superstructure consists of composite steel reinforced concrete blocks, which are prefabricated and combined at the construction site. To ensure the simultaneous inclusion in the work of the whole cross-section, the installation of the bridge superstructure structure by means of a hinged method or on solid scaffolding is provided.

Abstract
In conditions of rower crisis the questions of resource saving have gained special urgency in all spheres. Modern problems in the sphere of effective energy use are versatile and they start to influence architectural and building decisions more and more. A wide range of questions concerns providing buildings with natural illumination as artificial illumination together with central heating charges have got leading positions. They make more than a half of operational charges of a building. The most effective decision is to supply buildings with natural illumination but it is often connected with a few problems because it is important to remember about thermal stability of constructions.
It is known that a building loses less heat as it grows in width. It becomes more resistible to different climatic influences. But as the width of a building grows some hardly illuminated parts of buildings appear. It is possible to supply organizations with sunlight in remote parts of buildings regarding decrease of resource consumption (changing traditional approaches to building illumination with natural light). In the following article the generalization of variants of organization of natural illumination of hardly lighted areas is made. All the positive and negative sides are concerned.

Authors: Shoshin E A , Timokhin D K , Strahov A V 
Published: March 2020

Abstract
The article is devoted to the study of the cement stone hydrate phases formation in the presence of significant amounts (2%) of isomeric disaccharides - sucrose, maltose and lactose. Attention to disaccharides as modifying agents of cement stone is due to their ability to influence the ratio of high and low density cement gels in the composition of cement stone. To implement Portland cement hydration process in the presence of significant amounts of disaccharides cement grinding in the presence of carbohydrate solutions was used. It was found that the molecular structure of carbohydrate does not affect the elemental and phase composition of hydration products. Hydrosilicates in the presence of carbohydrates and aside of the molecular structure of the latter form the phases of the cryptocrystalline structure. The formation of cryptocrystalline phases is accompanied by occlusion of disaccharides; the residual content of disaccharides in the liquid phase of suspensions does not exceed 0.3% of the initial amount of modifying carbohydrate.

Published: March 2020

Abstract
The border area is a space in which there is a special regime of settlement development. Along the long border between Russia and China, there has historically been a cross-border relationship between settlements. Currently, each of them has its own mode of development, determined by socio-economic and political factors. The formation of a cross-border settlement zone in the North-East of China and the Far East is determined by integration processes, which are constrained by the implementation of different program directions of the two States. The Asian vector can be clearly traced in the economy and demography of the South of the Russian Far East. New Chinese cities are beginning to form functional and planning conglomerates with Russian settlements. Two divergent process (Chinese urbanization and suburbanization Russian) has led to the creation of new settlement systems cross – border and transcontinental. The novelty of the study lies in the fact that for the first time new forms of settlement in the border area – transboundary and transcontinental are considered; functional and planning features of their development are revealed.
