This article presents some results of the author’s dissertation research dedicated to formation of an architectural typology of high urbanized multifunctional units of urban structure of the largest cities (further HUMUUS) as centers of social activity, which include buildings, constructions, transportation equipment and open spaces, where human flows transpose, start and end with the purpose of bringing into this space a concentrated maximum of goods, services and information with minimum time expenditures. This article draws attention to the development analysis of the structure-forming functions of HUMUUS and their town planning and environmental impact on the surrounding area. The study of planning structures of the largest Russian cities (Samara, Kazan, Nizhny Novgorod) made it possible to identify a number of main objects, in which structure-forming functions of HUMUUS are materialized: railroad complex (historically formed, developed, dominated, system-wide road junction), transport interchange hub (providing intraurban messages), public office and business centers, leisure and entertainment centers, shopping centers. Basing on researches of Russian and foreign experience, it is possible to predict with full confidence the following trends and streams of environmental and urban development of HUMUUS in the near-term perspective: Strengthening of the environmental and urban frame by network evolution of HUMUUS; Inclusion of green areas of HUMUUS in the system of citywide green areas; Increment of the interest of the investors to the public road junction for the purpose of reorganization of them to full HUMUUS with all characteristics of high-urbanized and environmental and urban reorganization (separation of traffic and pedestrian flows, maximum capacity, multiple-level system, multifunctional, increase in landscaped green space, reconstruction of engineering systems and communications, the use of modern ecological building designs and finishing materials); Preferential development of the intracity HUMUUS with all the characteristics of intensification of using space (reduction in area of transporting communication with the help of multilevel junction, increment of a number of stories in a building, the use of the levels of the underground space, mechanization of horizontal communication, release of the territory for planting, use of intelligent eco-stabilizing systems of control and management of functioning HUMUUS); Development of the territorial growth trends of HUMUUS with reconstruction of the functional processes and environmental settings in joint junction area; Emphasis of landscape and recreational areas development; Strengthening the role of creation of living environment and planting in the existing urban planning and functional HUMUUS.

In this paper the author offers is the classification of the formulae of Finite Element Method. This classification help to orient in a huge number of published articles, as well as those to be published, which are dedicated to the problem of enhancing the efficiency of the most commonly used method. The third part of the article considers the variation formulations of FEM and the energy principles lying in the basis of it. If compared to the direct method, which is applied only to finite elements of a simple geometrical type, the variation formulations of FEM are applicable to the elements of any type. All the variation methods can be conventionally divided into two groups. The methods of the first group are based on the principle of energy functional stationarity - a potential system energy, additional energy or on the basis of these energies, which means the full energy. The methods of the second group are based on the variants of mathematical methods of weighted residuals for solving the differential equations, which in some cases can be handled according to the principle of possible displacements or extreme energy principles. The most widely used and multipurpose is the approach based on the use of energy principles coming from the energy conservation law: principle of possible changes in stress state, principle of possible change in stress-strain state.

Today works in cosmos and at great sea depths are becoming very current. In order to execute these works tanks with great mass perfection are needed, which represents the relation of the product of pressure and inner volume to its mass. Usually such tanks are usually produced as a cocoon by winding methods, which can be automated. The simplest model of a cocoon is a cylinder with hemispheric blinds at the edges. The radial stresses arise in thick walled composite cylinders due to anisotropic thermal shrinkage during cooling process after curing. It also can lead to formation of radial cracks. The results of the analyses when a material is simplified to a homogenous orthotropic material show a very small residual radial stress value. In this paper we have used discrete model to evaluate residual radial stresses in thick-walled unidirectional filament wound cylinder and the results were compared to the results of homogenous orthotropic model.

The increase in noise level at cities is increasing the requirements to functional interaction of road users - pedestrians and drivers - with the parameters of the environment as a leading component of Afferentation synthesis in the complicated complex of locomotive activity. City noise is one of the most widespread factors of unfavorable living and working conditions. The noise of high intensity provokes diseases, lowers labor activity. At present, many large cities pay much attention to electric vehicles. The authors present an analysis of the poor state of tram track in areas of high noise and vibration of car and under-sleeper base design. A negative effect of noise and vibration on the formation of urban areas environment is shown as well as the impact of these conditions on the person. The advantages of the application of electric transport are specified, noise displacement curve of railway and under sleeper base is plotted depending on the frequency of the applied load and the modulus of elasticity, as well as under sleeper base vibroacceleration depending on time. The authors offer a systematic study on the basis of a mathematical model of the sources of noise in the process of a tram motion.

Initial and boundary conditions are always given for solving the problem of calculating the interaction of tunnels and other underground structures with soil and rocks. The same conditions are set for calculating the surface buildings. These initial data for calculation are divided into three groups: 1) the geometrical shape of the layers of rocks (geological structure); 2) the parameters of the strength and compressibility of rocks; 3) compressive stresses in the array. These data all over the world are set with engineering surveys. In engineering surveys there are good methods of determining the source of the data 1 and 2. But there is no available methodology for determining the natural stress state. Therefore, compressive and tensile stresses are usually determined by mathematical modeling. The calculation of the compressive stresses is done on the basis of the following hypotheses: compressive stresses are created by the weight of rocks; they go down in proportion to the density of rocks; the main normal stress is has a vertical direction; normal stress in horizontal direction is smaller. The value of the horizontal stress is was calculated using Poisson’s ratio. This hypothesis of the nineteenth century was used another 50 years ago, when it was not known exactly about the movement of the continents and when compressive stresses in the earth’s crust have not yet been measured. Today a universal application of this hypothesis is not correct. Now the application of this hypothesis in many cases is not correct. In this research paper an attempt is made to specify the area, in which the above hypothesis can be used. This is done on the basis of current scientific evidence. Abroad this way of calculating tunnels and other underground structures and bases of buildings should be done taking into account the real field of natural stresses. The geological characteristics of the location of the axes of stresses in soil body are based on the study of fractures. Also the article shows the influence of the surface topography of the territory on stress in soil. In order to draw conclusions the author uses his observations of the construction in Siberia and Mongolia, as well as publications of other scientists. The author notes that in engineering surveys for construction of tunnels, high-rise dams, high rise buildings there is no good method of determining the natural stresses in rocks and soils, which is equal in accuracy to the methods of construction of geological sections and methods for determining the estimated characteristics of the soil. This gap needs to be filled. The possible direction of work is: to combine the methods of direct measurements of compressive stresses with indirect geophysical methods and computer modeling.

The mechanical-geometric model of the suspension filtering in the porous media is considered. Suspended solid particles of the same size move with suspension flow through the porous media - a solid body with pores - channels of constant cross section. It is assumed that the particles pass freely through the pores of large diameter and are stuck at the inlet of pores that are smaller than the particle size. It is considered that one particle can clog only one small pore and vice versa. The particles stuck in the pores remain motionless and form a deposit. The concentrations of suspended and retained particles satisfy a quasilinear hyperbolic system of partial differential equations of the first order, obtained as a result of macro-averaging of micro-stochastic diffusion equations. Initially the porous media contains no particles and both concentrations are equal to zero; the suspension supplied to the porous media inlet has a constant concentration of suspended particles. The flow of particles moves in the porous media with a constant speed, before the wave front the concentrations of suspended and retained particles are zero. Assuming that the filtration coefficient is small we construct an asymptotic solution of the filtration problem over the concentration front. The terms of the asymptotic expansions satisfy linear partial differential equations of the first order and are determined successively in an explicit form. It is shown that in the simplest case the asymptotics found matches the known asymptotic expansion of the solution near the concentration front.

Today the technologies of trenchless reconstruction of pipelines are becoming
more and more widely used in Russia and abroad. One of the most perspective is methods is shock-free destruction of the old pipeline being replaced with the help of hydraulic installations with working mechanism representing a cutting unit with knife disks and a conic expander. A construction of a working mechanism, which allows making trenchless reconstruction of pipelines of different diameters, is optimized and patented and its developmental prototype is manufactured. The dependence of pipeline cutting force from knifes obtusion of the working mechanisms. The cutting force of old steel pipelines with obtuse knife increases proportional to the value of its obtusion. Two stands for endurance tests of the knifes in laboratory environment are offered and patented.

The authors present an analysis of various types of internal protective pipeline coatings to ensure the strength and hydraulic characteristics of a remodeled pipeline and related coating methods for effective trenchless renovation of engineering systems, water supply systems and sanitation. As protective coating the authors considered a round profile tube of a smaller diameter than of the old pipe, close to the old pipe, sprayed lining on the basis of inorganic and inorganic materials. The article analyzes the methods of trenchless renovation for applying protective coatings: routing in the old pipeline of new pipes made of polymeric materials or polymeric sleeves, centrifugal spraying on the inner surface of pipelines’ inorganic and organic protective coatings. Special attention was paid to bag technology, providing the required strength properties at specific values of the modulus of elasticity and a number of external factors such as the depth of the existing pipe, the existence and magnitude of the horizon groundwater over it. Also attention is paid to the application technology of tape coatings ribbed profile on the inner surface of pipelines. This technology has a unique feature, which is the ability of recoverable pipeline functioning during its renovation by winding an endless belt and the formation of a new pipe. The tape coating winding is carried out by different types of spiral winding machines. The thickness of the protective coating layer forming the tube remains minimal. Inorganic cement-sand and organic coatings were considered as alternative options for repair of pipelines, which allow to localize the defects in the form of a fistula, minor cracks and other damages. However it is noted that a cement-sandy covering is inferior to organic, because it does not provide the strength characteristics of the pipeline system. The main advantage of the organic coating is mudding fistula of a large diameter, making a high wear-resisting pipe, ensuring a smooth surface. Then the protective coating almost merges with the old pipeline. The conclusion is made on the necessity of taking account of the potential for energy saving in case of various protective coatings and implemented trenchless technologies application.

In the article the short historical review on the design of sanitary rooms and their configurations is given. The main errors of the recent years, which led to the decrease in accommodation convenience because of the wrong approach from both the architect and engineers, are given. It is possible to use a small useful area for sanitary facilities, but it is connected with the lack of possibility of connecting washing and dishwashers. The author considers the options of engineering equipment placement in sanitary rooms taking into account the convenience of use, safety, and also resource-saving aspect. Various solutions on the organization of heating and ventilation are provided. The possible technical solutions allowing solving a flooding problem of the first floors in elite housing estates in case of accident are offered with the help of full waterproofing of sanitary rooms, and also the whole area of the apartment. The main attention was focused on the improvements of sanitary rooms for one-room and two-room apartments, which are the most demanded in the modern market of real estate. Layout solutions of the reduced bathrooms on the placement of the necessary equipment with choice justification are provided. The attention is paid to the layout solution for modern kitchens on order to increase their comfort by the use of special two-section sinks, and also a grinder of food waste in order to allow to lower the load of the systems of rubbish disposal of a building, by dumping the crushed garbage in an internal sewer network. Various options of evolutionary development of sanitary rooms for increasing the comfort degree are given. First of all, the development should happen in the direction of not only sanitation and hygiene, but also of the maintenance of the physical health of the people living in the building. It can be carried out by increase in a useful area of sanitary rooms, installation of exercise machines, medical bathtubs and a Jacuzzi, which allows receiving good relaxation after a difficult day. Also one more direction will be the organization in occupations of an aquacycling, so-called water trainings in a special bathtub by means of exercise machines for strengthening of health of the population.

The author considered the problem statement on the pipes freezing in emergency regimes of building engineering systems and external pipe nets using liquid water as working fluid under boundary conditions of the 3rd type. This problem is a high-priority task now because of actualization of building standards in Russian Federation and because of the increasing requirements to safety and security of heat supply. That’s why it is very important to find a simple but accurate enough dependence for the freezing time in pipe nets. The system of differential and algebraic equations of external heat exchange and internal heat transfer with account for heat ingress from hydraulic friction at water flow and Stephan’s condition on the freezing front is presented. The analytical solution of the given system is obtained as a quadrature for the dependence of the current coordinate of the freezing front. The results of numerical calculation of the corresponding integral are shown and their comparison with the former author’s researches concerning the solution of the considered problem at the boundary conditions of the 1st type is conducted. It is shown that the account of intensity of external heat exchange causes retarding of freezing because of adding thermal resistance on the external surface of the pipe. The former author’s conclusion on the existence of the ultimate water velocity, when freezing doesn’t take place, is verified. The area of use of the presented dependence is found. The obtained model contains is easy to use in engineering practice, especially during preliminary calculations. The presentation is illustrated with numerical and graphical examples.

The practical projections of cyclic theories are of a great interest. Our preferences moved again from apartment houses and vertical cities to low-rise buildings. Circles set the development vector for natural, human sciences and sciences on society. The article researches the problem of cyclic development of scientific schools and their innovation ideas in the sphere of space-territory property development. The phases of the cycle were researched on the example of Bauhaus architecture school. This enables to reveal the demands and specifics of the development of new technological platforms, as well as to create the effective formats of public-private partnership. Cyclicity of business activity development under the conditions of awareness of the evolution of senses of interdisciplinary approaches utilization permits to produce the adequate development paradigm.

The article reveals the possibility of creating and implementing teaching conditions for the rational organization of the independent work of first-year students in state of adaptation to the study of the course of engineering drawing. Theoretical and methodological aspects of students’ independent work are presented: types and forms of organization and control, training and methodological support of their independent work. The authors used such an approach to independent work organization: teacher-led classes during the main types of training activities (lectures, practical and laboratory work); form of organization of training (extracurricular), and also self study using innovative teaching methods promotes creative activities of students and the development of competencies of a future skilled construction industry professional. The role of modern information and communication technologies in independent work of students was specified. According to the degree of coverage of students, taking into account individual characteristics and different levels of preparedness, the following forms of independent work organization were detached: individual, differentiated and front.In the process of engineering graphics studying it is recommended to use the following basic forms of independent work: ongoing work with the lecture material; selection and study of literature and electronic sources of information on the problems of the discipline; preparation for the main classroom training; performing calculation and graphic works; work in student scientific societies and carrying out research work; participation in scientific conferences, seminars and other. Emphasis on the formation of students’ skills in working with different types of educational and scientific literature, the ability to analyze, organize information in electronical library systems, open educational resources.
