The questions related to the study of various varying factors on the strength of normal sections in beams. Here's a program of research by one methodology designed to study the effect of the type and content of steel reinforcement and externally composite on the strength of normal sections that have not previously been investigated.
Keywords: Concrete, reinforced concrete, the percentage of reinforcement, carbon frp sheets, fiberglass, laminates
Some information was provided about the influence of type and percent of steel and composite reinforcement, on the strength and deformability in strengthened reinforced concrete beams. It was found, that the increment degree of strength in beams decreases by the increasing in percentage of steel reinforcement, especially, when a carbon fiber plastics with hot and cold hardening was used.
Keywords: Concrete, reinforced concrete, steel, composite, the reinforcement rate, the efficiency of strengthening , the varied factors, strength, limit strength, maximum allowable deflection, deformation.
An analysis for the influence, of type and quantity of steel and composite reinforcement, on the normal cracks development, at different load levels, and by the maximum allowable deflection in beams. It was Found that throughout the load range, the reference beams are most cracked. The reduction degree in crack width depends on the strength and percentage of the steel reinforcement.
Keywords: concrete, reinforced concrete, steel, fiberglass, carbon fiber, laminate, maximum allowable crack width, load level, the development of cracks, the relative width
It was provided some information about the character of crack formation and failure of prototypes, which strengthened by three deferent type of composite materials. It was fixed some increased in the crack’s number in beams which reinforced with glass fiber canvas, and 6 deferent mode of failure in strengthened beams.

Development of urban areas, especially Rostov-on-Don, which is one the largest city of the south of Russia, should be based on a comprehensive assessment and analysis of the structure of housing stock and engineering services, which provide all types of resources for the city. Research of the structure of housing stock, analysis of residential and private housings, municipal and business buildings, information on the territorial distribution of these objects with reference to the topography would allow to create a reliable information base for the development of district heating schemes. Housing stock of Rostov-on-Don was ranked by the year of construction, number of floors and material of the wall. The article assesses the providing of municipal and business buildings, kindergartens, schools, institutions consumer services, culture and sport institutions.
Keywords: urban development, energy, heating, year of construction, material of walls, floors
Some information was provided about the experimental values of crack width in reinforced concrete beams, which strengthened by three deferent types of glass and carbon fiber reinforced plastics. It was found that, when the strength and modulus of composite are increased, to the width in normal cracks is reduced. Having U-shaped clamps, anchors at the ends of the composite caused a greater reducing in their development. These factors should be considered in theoretical matters.
Keywords: Concrete, reinforced concrete, the reference beams, prototypes, cracks, crack width, the level of the composite reinforcement
The article is devoted to the peculiarities of eclecticism in the central part of the city of Rostov-on-Don at the turn of the XIX - XX centuries. The Russian architecture in the years 1840-1850. prevailing eclecticism. All the variety of its variants is reduced in the Russian architecture in two varieties: the first of which dates back to the tradition of a warrant (neogrek, Renaissance, Baroque, Rococo, pampeyansky), and the second - to the non-classical heritage (Byzantine, Russian, Gothic, Romanesque styles). In Rostov architecture became widespread both varieties. This was facilitated not only the diversity of life in the city, the intensive development of trade industry, generating a variety of new types of buildings, but also the technical progress by which the means of production have changed.

The article is devoted to a brief presentation style features Constructivism in the city of Rostov-on-Don. The construction boom in the city begins with the 1920s, a new style of Constructivism, had already fully declared itself in the capital. In the early 1930's. architectural development in Rostov took the path of development of the principles of the avant-garde. The very principles and forms of avant-garde come to the Rostov practice with some delay - as a kind of well-established tradition, continuity of development projects in Rostov architects

"Examines the relationship of the concepts on the example of post-war reconstruction of post-war reconstruction of the city of Rostov-on-Don.
In 1945, the Chairman of the Committee on Architecture AG Mordvinov announced seven conditions under which you can create the city.
In 1945, the development of the urban plan of rebuilding the city of Rostov-on-Don was appointed academician of architecture VN Semenov.
In 1949. master plan was finalized at the construction site.
In general, the basic idea of the architect was executed. Among the fifteen cities prone to restore the city of Rostov was restored in all seven conditions put forward by the Chairman and the Committee for Architecture AG Mordvinov, projected architecture academician VN Semenov and given a reality by means of the chief architect of YA Rehbein."
