PROSPECTS OF DEVELOPMENT OF HIGH-RISE BUILDINGS TYPOLOGY FUTURE CITY
GENERALOV V.P., GENERALOVA E.M.
Abstract

The current questions of prospects of modern cities development are viewed in the light of steady growth of population and urbanization connected with enhancement of cities role in social development. The problem of urban densification and the prospectivity of large cities vertical growth are considered. China practice is analyzed because this state is acknowledged global leader in the matter of high-rise building and its achievements can be useful for the Russian Federation. The article concerns activities of the Council on Tall Buildings and Urban Habitat (CTBUH) researching high-rise building. Modern approaches to highrise buildings typology are examined, their main point is defined as «mini-city in city».

GRAPHICALLY ANALYTICAL APPROACH TO THE DEFINITION FUNCTIONAL SPECIALIZATION OBJECTS OF THE TRADE IN THE TOWN PLANNING STRUCTURE
KARAKOVA T.V.
Abstract

In professional activities of an architect-city planner the important place is occupied by the problems of determination of various functional objects locations. During the formation of a spatial network optimization schemes of retail facilities in the territory of Samara the questions not only about the placement of objects, but also about their functional specialization are revealed. These questions resolving was the main task of a city planner, able to provide a number of emerging risks to the business framework. Avoiding of retail facilities excessive competition in functional spatial aspect and smart zoning require new professional approaches and methodologies, among which the most important is graphical analytic approach.

CONSIDERATION ON THE POSSIBILITY OF SAMARA'S ROAD NETWORK DEVELOPMENT AT THE STAGE OF MASTER PLAN DESIGNING
LAVROV S.E.
Abstract

The article views transport availability degradation in Samara. Options for additional throughput capability of transport hubs are presented. Design limitations of road junctions in different levels in urban areas are considered. The possibility of realization of master plan of highwayroad network development in Samara on one line example is analyzed. Comprehensive analysis of mutual combination of horizontal and vertical alignment of adjacent traffic intersections in the particular conditions of their placement on the basis of compliance with regulatory requirements is made. The main problems of realization of master plan of highwayroad network development are formulated. Proposals for the creation of a new mechanism for master plan development, proposals for the specification of plan of continuous motion lines creation are given taking into account real economic conditions.

MODERN METHODS TO AERO PHOTOFILMING IN THE ARCHITECTURAL AND PLANNING ANALYSIS OF THE URBAN AREA
LITVINOV D.V.
Abstract

In article the modern aerial photography from unmanned aerial vehicles as one of methods of the analysis of city building and the territory in design and exploration work is considered. A number of advantages of aerial photography before land photographing is allocated. The retrospective analysis of aerial photography, allowing to track its development from amateur to the professional is carried out. Its application in town planning, reconstruction and new construction is defined. Two main types of aerial photography, used in construction planned and, - «perspective» are «allocated».

ENVIRONMENTAL CRITERIA IN FORMING SPATIAL BORDER ARCHITECTURE AND URBAN PLANNING
RADULOVA Y.I.
Abstract

The concept of international environmental standards is presented. Environmental criteria in architecture and urban planning are viewed. Identify environmental problems in the formation of spatial boundaries of architecture and urban planning. In design practice the examples of new environmental approaches including energy saving, air cleansing, reducing hazardous waste in manufacturing and construction and increasing the environment visual comfort are such systems of international environmental standards as american LEED, english BREEAM and german DGNB.

COMPUTER SIMULATION OF WATER FLOW IN CAPACITIVE STRUCTURES DURING START-UP WORKS AND EXPLOITATION
BARINOV A.M.
Abstract

As a result of commissioning of rainwater treatment installation at the Adler sewage treatment plants in Sochi its signifi cant design disadvantages are revealed. Thin layer tank unit doesn’t meet project requirements. Computer hydrodynamic model of an existing plant is built to obtain the coefficient of volume usage. Also design changes that improve the performance of the installation are proposed and simulated.

USE OF INFORMATION SYSTEMS TO IMPROVE THE EFFICIENCY OF WATER SUPPLY COMPANIES (THROUGH THE EXAMPLE OF TUMEN VODOKANAL)
IVANOV V.M., BYCHKOV D.A., IVANOVA T.Y., BAKHTINA I.A.
Abstract

In the article the steps required to create a detailed hydraulic model of the water network Tumen with the use of geographic information systems (GIS) «Zulu» are described. The effectiveness of the design scheme for solving a number of applied problems of water utility network optimization, implementation of programs to reduce pressure and planning for a case of emergency are shown. Real-life experience of GIS using for accidents analyze, certification, introduction of the water supply objects single classifier are presented. Perspective ways of information system development are viewed.

EVALUATION OF STRAINS OF RUN-OF-RIVER UNIT EARTH DAM
BAL’ZANNIKOV M.I.
Abstract

The earth dam of run-of-river unit - Kuybishevskaya hydro-electric power station on Volga - is viewed. The main characteristics of earth dam, particularities of its construction and exploitation are presented. The factors that have changed initial design specifications of its exploitation are highlighted. Evaluation of geometrics of earth dam in different exploitation periods and potential causes of their tolerance are analyzed. Measures for exploitation reliability growth are proposed.

EVALUATION OF FIRE-RESISTANCE OF STRUT REINFORCED CONCRETE STRUCTURES
ILYIN N.A., PANFILOV D.A., LITVINOV D.V., SLAVKIN P.N.
Abstract

In SGASU a new engineering solution for buildings fire protection is developped. It’s especially efficient for classification of reinforced concrete structures according to their resistance to high-temperature impact in case of fire or technological emergency that gives an opportunity to use a structure with actual fire resistance grading in buildings of different structural fire hazard. Evaluation of actual fi re resistance grading by engineering analysis (as opposed to inplace tests of reinforced concrete structures) makes possible resource and energy saving.

STUDY OF SPLIT-SYSTEM IN HEATING MODE
KARTASHOVA A.O., KORTYAEVA D.O., KULYASOVA K.E., TSYNAEVA A.A.
Abstract

In this article there is a study of the heat pump for heating the premises of a public building (academic building of Samara State University of Architecture and Civil Engineering). The aim of the work was to determine the parameters of the heat pump and the impact of his work on the microclimate parameters of heated space. As the heat pump was activated split-system, operating in the heating mode; analysis was performed changing the state of the working fluid (Freon-R410A) used in this split-system. The studies revealed that the use of the heat pump (split system, operating in heating mode) allows you to maintain optimum parameters of the indoor environment. With the help of the tests revealed that the use of split-system as a heating system reduces the inertia of the system to ensure the indoor environment. This leads to maintain a comfortable environment for human habitation when the external operating conditions typical of the autumn-spring period, and demonstrates the effectiveness of the use of split systems, the use of which may in residential and public buildings. Furthermore, was prepared a graph of the room temperature before and after the operation of a split system.

UNSTEADY HYDRODYNAMIC PROCESSES IN THE SLIT GAPS NONCONTACT SEALS IN A STEP CHANGE IN PRESSURE
KRESTIN E.A.
Abstract

Determination of leakage of fluid through the slotted annular gaps in dynamic studies leads to the discrepancy between the theoretical and experimental results. This discrepancy is particularly large for non-stationary processes in hydraulic systems. Dynamic characteristics of annular sealing cracks in a typical non-contact seals in stepwise (unit step) change of pressure are found. The velocity profile, the flow of leaks, the force of viscous friction on the channel wall are determined, the relaxation during the defined transition and the weighting function of the sealing gap are viewed.
