The family of multilayered finite elements for the analysis of plates and shells of variable thickness
Authors: Agapov Vladimir
Published: April 2019

Urban development requires careful attitude to environment on the one hand and protection of the population from the natural phenomena on the other. To solve these problems, various building structures are used, in which slabs and shells of variable thickness find the wide application. In this work, the family of multilayered finite elements for the analysis of plates and shells of variable thickness is described. The family is based on the simplest flat triangular element of the Kirchhoff type. The lateral displacements in this element are approximated by an incomplete cubic polynomial. Such an element is unsuitable for practical use, but on its basis, improved elements of triangular and quadrilateral shape are built. Particular attention is paid to taking into account the variability of the cross-section. The results of the developed elements testing are presented, and the advantages of their use in the practice of designing and calculating the structures are shown.
Insulating sheath system and energy efficiency of buildings
Authors: Bobrova Ekaterina , Pilipenko Anton , Zhukov Alexey
Published: April 2019

The article discusses the results of thermal imaging monitoring of building structures with and without insulation. Research and thermal and physical calculations showed that heat loss from the premises is determined by two groups of factors: surface loss depending on thermal conductivity, as well as vapor and air permeability of enclosing elements and heat loss at all types of joints, fasteners, etc. Thermal insulation with plate materials significantly reduces heat losses, but at the same time, heat flows through the joints between the heat-insulating plates and in the areas of their contact with other structures, necessitating the use of steam and waterproof windproof roll materials. The usage of elastic and thermoplastic materials in the insulation circuit allows minimizing heat loss at the joints between the heat-insulating elements and along the smooth surface of the wall due to the low air and vapor permeability of the material. In the systems of frame cottages, when used as a thermal insulation of rolled foam-polyethylene, it becomes possible to form a seamless insulating shell of a building. This is made possible by connecting individual sheets of polyethylene foam into a lock, followed by hot air welding. Seamless insulation systems are used both in the construction of cottages and in the construction of frame and frameless logistic facilities and housing and communal services.

Published: April 2019

Structures in the form of ribbed panels with sheathings from sheet materials are used in construction of buildings and structures of various purposes: civil, industrial, agricultural, etc. Panels are universal enclosures and supporting structures, they can be used as coverings, floors, walls. Ribbed coating slabs simultaneously perform the functions of roof purline, floorboards, sheathing, provide heat and sound protection of the building. They are characterized by unification, high level of factory readiness; the ability to control the strength, sound and heat-insulating properties, and low density of materials used, which allows significantly reducing the cost of laying the foundation of the building. The paper presents the results of investigations of the influence of various parameters on the stress-strain state of panels (type of joints, coefficient of stiffness of the bonded joints, the magnitude of the span, the width of the panel, and the material of anisotropic sheathing).To solve this problem, the well-known solution of the plane stress problem is used (Faylon method), in which the constants of integration are determined as the Fourier series expansion coefficient of contour loads. As a result of numerical researches, reduction coefficients for bendable ribbed wood-composite panels with mechanical joints were obtained.

Authors: Morozovskiy Pavel , Kulish Ilya , Kryzhanovskii Nikita , Filatov Vladimir , Romanovich Marina
Published: April 2019

For the calculation of building structures under the influence of external dynamic loads, it is necessary to know the eigen frequencies of the structures themselves in order to prevent such a phenomenon as resonance. Steel has distinctive properties from concrete, so its consideration is necessary to determine the eigen frequency of the whole structure. This article presents the calculation of the cantilever beam analytically and in the software package Abaqus for linear and volumetric problems with the interaction of concrete and reinforcement. Due to the reinforcement, the beam eigen frequencies differ from the eigen frequency of the conventional rigidly fixed rod, as evidenced by the results of the calculation.

Authors: Ishchenko Aleksandr , Zotov Ivan
Published: April 2019

The paper deals with the lateral buckling problem of a freely supported wooden strip with a constant narrow cross section, loaded with a local force in the middle of the span. A differential equation is given for cases when the force is applied out of the gravity section center. Strain-energy method was used in the study of beam lateral buckling. In the case when the load is applied in the center of gravity, problem comes down to a generalized characteristic equation. The correlation between the magnitude of the critical force and the application point of the load was obtained. The linear approximating function was identified for the indicated dependence. The obtained results are compared with an analytical solution using the Bessel functions and a numerical iterative method.

Authors: Yuilin He , Beljatynskij Andrii , Ishchenko Alexander
Published: April 2019

Traffic congestion is a world problem and an important factor restricting urban development. In order to solve the problem of urban traffic congestion, this paper takes the traffic flow theory and the intersection channel design theory as the research foundation, and conducts in-depth research on the causes of congestion at the intersection and the corresponding solutions, and proposes to cancel the traffic lights at the intersection without any stagnation. This paper proposes a new intersection design scheme, which is like the veins of the flower veins to channel the design intersection, cancel the signal light, and the vehicle can pass through the intersection without stagnation. It proposes a new solution to solve the traffic congestion problem. This new design allows the traffic flow to be spatially separated on the horizontal plane, and due to the cancellation of the signal lights, there is no signal waiting at the intersection, and the vehicle can travel without stopping at the intersection. At the same time, this paper also establishes a plane intersection service capability evaluation system based on simulation and quantitative calculation, which provides an evaluation index and proof basis for the non-stagnation driving channel design of the non-roundabout intersection.

Authors: Qaoud Rami , Djamal Alkama
Published: April 2019

The urban fabric of the desert cities is based on the principle of reducing the impact of urban canyons on direct solar radiation. Here comes this research, which is based on a comparative study of the periods of direct solarisation and values of the solar energy of urban canyons via two urban fabrics that have different building densities, where the ratio between L/W is different. In order to obtain the real values of the solar energy (thermal, lighting), the test field was examined every two hours, each three consecutive days. The measurement stations are positioned by the three types of the relationship between L/W, (L≥2w, L=w, L≤0.5w). According to the results, we noticed and recorded the difference in the periods of direct solarization between the types of urban engineering canyons, reaching 6 hours a day, the difference in thermal values of air, reaching 4 °C, and the difference in periods of direct natural lighting, reaching 6 hours. It should be noted that the role of the relationship between L/W is to protect the urban canyons by reducing the impact of direct solar radiation on urban canyons, providing longer hours of shading, and reducing solar energy levels (thermal, lighting) at the urban canyons. This research is classified under the research axis (the studies of external spaces in the urban environment according to the bioclimatic approach and geographic approach). But this research aims to focus on the tracking and studying the distribution of the solar radiation - thermal radiation and lighting radiation - in different types of street canyons by comparing the study of the direct solarization periods of each type and the quantity of solar energy collected during the solarization periods.

Published: April 2019

The article highlights the problem of sustainable development of the living environment and living standards of the population, which is rather relevant for the governments of most developed countries including Russia. In recent years, the anthropogenic impact of aggressive external medium on the quality of human life increases, which reduces the working capacity of citizens and consequently lowers their labor productivity. The implementation of «Concept for the Transition of the Russian Federation to Sustainable Development», which was elaborated and adopted in 1996, implies a gradual transition to the balanced solution of pressing social and economic issues and problems that concern preserving natural resources in order to meet the needs of present and future generations. The authors emphasized the need for a scientific-theoretical and methodological substantiation of preparing the strategic priorities of the housing development planning with a focus on creating competitive residential housing and renovation projects. The authors note that the greening of housing construction and renovation industry helps to ensure high living standards and contributes not only to improving human well-being and increasing person’s lifetime but also enhances his or her working capacity and labor productivity. The elaboration of strategic priorities of the housing industry development involves the consideration of current challenges of the national economy.
The energy efficient lighting in kindergartens
Authors: Gulbinas Alexandra , Petuhova Vera
Published: April 2019

The article discusses the results of a survey of the light environment parameters in preschool educational institutions in Russia. Improving the light environment means, on the one hand, maintaining the quality of lighting, and on the other hand, improving energy efficiency and thereby reducing the financial burden. The first step in improving energy efficiency can be called an energy audit of educational institutions and the development of economically viable measures to save energy. The energy efficiency indicator was put in the first place, and to some extent the quality indicators of lighting were forgotten (for example, such as color rendition, color temperature, uniformity of illumination and etc). During the survey of the light environment, we made disappointing conclusions about the inconsistency with the parameters of regulatory documents. The lack of visible results of the implementation of energy-based solutions makes the kindergarten’s management adhere to standard solutions for improving efficiency and not worrying about the quality of lighting. It is necessary to comprehensively consider the issues of improving the light environment and take into account not only the energy efficiency, but also the quality indicators of lighting systems. In turn, the number of indicators of energy efficiency of buildings must be expanded.

Published: April 2019

Windows are an essential part of almost every civil building. The existing approach for designing windows is based on ensuring minimum requirements to provide natural lighting functions, thermal protection, etc. This approach does not take into account the interrelationship of certain technical characteristics of windows (for example, heat and lighting characteristics). This leads to the appearance of typical problems at the stage of operating the building (insufficient day light, poor ventilation, etc.). In this work, an analysis of functional and technical requirements of windows of civil buildings was conducted. The review of modern researches of optimal window designs and interrelation of certain technical characteristics of window between themselves was conducted. On the basis of this analysis, the concept of a new complex window design method was proposed. This method is based on the fact that windows are both bearing and enclosing elements of the building. The use of this method will create the standard design solutions of windows for civil buildings of different functional purposes and different climatic areas of construction.

Protection of intellectual property of an architect
Authors: Zhilskiy Nicolay , Shariapova Emma , Matveeva Marina
Published: April 2019

In the paper, the authors raise the issue of protecting the copyright of an architect. One of the ways to protect it is the trial. The RF Constitution guarantees judicial protection of rights and freedoms. Recently, in the Russian Federation, the number of appeals to the court for copyright protection has increased, indicating a large number of infringements of intellectual property rights of architects. The study of the authors showed that often the cause of litigation is the discrepancy of the values of the objects of copyright of the architect. To interpret such concepts as “architectural solution”, “architectural design”, “architect’s concept”, “architect’s idea” and others, the court is forced to involve specialists whose opinions in the court decision become the source of law, which contradicts the theory of state and law. The authors believe that the legislative consolidation of clear, certain essential features of the conceptual and categorical framework used in architectural activity is the improvement of the protection mechanism for the works of architects that are the result of their creative activity.

Authors: Arinshtein Eduard , Tatosov Aleksey , Kutrunov Vladimir , Yanbikova Yulia
Published: April 2019

The Stefan problem in the heat propagation in a two-phase region, which is relevant in the study of the processes of motion of the freezing boundary, taking into account the properties of both frozen and thawed soil, has been considered. In contrast to the standard approach to solving the Stefan problem, when the temperature of one phase is fixed, the paper considers the case when the heat fluxes are determined by the temperature distribution both in one and the other phase. This allows us to clarify the process of the phase boundary motion (the boundary of soil freezing), which must be taken into account when founding the carcasses of the construction of high-rise buildings. The solution is given in a form that makes it possible to implement by numerical methods on an accessible electronic computer technology.

A functional relationship is obtained between the Froude number in an arbitrary section of the Venturi channel and its width normalized by the width of the critical section. It is established that within a rectilinear gorge portion of a Venturi channel, the flow is unstable, which is related to the proximity of its parameters to the critical ones. The method of optimization of a profile of a Venturi channel with a dividing cross-section in a gorge that does not contain empirical coefficients is considered. It is shown that the proposed method allows determining all main geometric parameters and hydraulic characteristics of the Venturi flume, including its flow rate coefficient, distribution of depths and flow velocities along the length of a flume with a relative error of ±1%.

The paper considers the problematic issues of the special aspects of solution of the problems of modern geodynamics and technogenic geomechanics in oil and gas fields based on the results of re-levelling. The disadvantages and fundamental errors traditionally made by mining and land surveyors in organizing and performing re-levelling on the territories of oil and gas fields are given. The results of high precision levelling, obtained on the territory of an oil and gas field using the program and goal-oriented approach for its formulation, are presented. The representativeness and sufficient accuracy of obtaining the results of re-levelling allowed us to establish significant speeds of geodynamic and technogenic displacements of the earth’s surface (0.4 - 3.6 mm/year) in the shortest time possible with high economic efficiency.

This article covers a variety of topics on blockchain and the impact that digital encryption and social engineering will have on finance society. In modernized mortgage market, exchange would happen naturally, allowing users to benefit from a web of trust, where parties do not need to be in a direct relationship with each other to reap rewards from referrals that originate from multiple parties. Pseudonymity and honesty are properties that blockchains handle natively, and this is a candidate solution to the “transparency” problem in lending and borrowing, which acts as a trust inhibitor at scale for many interactions.

As of the end of 2017, in Moscow, there are 286 mapped five-story fully-assembled residential buildings of K-7, II-32, II-35, 1605-AM, 1MG-300 series with total area of 1046,7 thousand square meters. They were built at the beginning of the era of mass construction, in 1959 - 1962 years, and were distinguished by thin outer walls of lightweight ribbed expanded clay panels with unstable thermal protection properties. The technologies used in the construction of such buildings do not allow reconstructing them. Nowadays, the task of demolition of the neighborhood of five-storey houses in Moscow with the maximum possible reduction in terms of production of works and the maximum quality of work is very important. It is also necessary to ensure safe work and compliance with all sanitary standards. The order of execution of the works has a mathematical solution method. It identifies issues that arise in the alternating sections performing the process of demolition.

In article, development of ethnoeconomy is considered as a possibility of overcoming an imbalance in the agrarian sector of the Russian Federation. The carried-out analysis of the definition “ethnoeconomy” has revealed the need of addition of innovative component in interpretation of this term. It will allow giving a new look to traditional forms of managing or carrying out production of ethnic goods according to the latest technologies. Prospects of a clustering of business activity in the sphere of ethnic economy in Krasnodar Region are considered. It is defined that it promotes increase in efficiency of interaction of subjects of small and medium business and also growth of their internal potential in modern economic conditions. It is revealed that the lack of infrastructure for realization of the ethnic production is one of the main problems of ethnic economy of any region of the Russian Federation. The authors consider that “successful” ethnic production should have a certain popularity, to be eco-friendly, to conform to the quality standards, and to possess original packing. The authors have considered theoretical prerequisites of formation of the Cossack farms of innovative type as innovative elements of economic space of the territory.
