At the beginning of the 19th century balconies usually arranged in a mansion on the second floor. Most often, they were made of wooden structures with their own vertical supports. In the second half of the 19th century the use of cast-iron and steel struts rail rolling. Balcony plates are in the form of brick svodikov on rails. In tenement houses balconies began to carry out the scheme on the console (embedded in the masonry exterior walls), departure balconies declined.
At the beginning of the 20th century in the construction of a new material - concrete. Supporting structures balconies as steel beams cantilevered embedded in the masonry. Filling the balcony slabs of concrete performed (rubble mixed with concrete, rebar steel rod in the form of a knitted mesh).
In the mid-60 ÷ early 70s. 20th century 5-storey buildings with brick walls were used precast concrete balcony slabs, cantilever embedded in the masonry (250 mm).

"Application of solar energy in supplying various infrastructure units is urgent these days. Traditionally these were the centralized urban heating systems, which were used for heating buildings. The suggested heating system is composed of solar collectors with a total area of 44.16 m2 and with a volume flow of hot water to the consumer of 1.5 m3/h. Computer-aided heating circuit consists of traditional circuits, composed of solar collectors, circulation pump and a lamellar heat exchanger. Additionally, the scheme is extended by a fixed temperature water tank and a circuit, which interfaces the heating systems. They will be in their turn separated by a heat exchanger. The equipment also provides an opportunity of organizing a reverse pairing with the heating systems to return the excess heat into the network. This scheme has several modes of operation. In the conditions of nighttime, cloudy afternoon, light fog or smog water heating is provided by a central source. If during daytime, while being heated directly by the sun the water gets overheated the overheated water discharge mode is switched on automatically to discharge excess heat to a central heating system. The scheme provides for a “solar connectors and central source of heat parallel operation mode” to maintain the desired temperature, for example in the morning. According to the results of observations the share of water heating due to the solar collectors in summer is on average about 75%. Shared usage of central source of heat and solar collectors allows to efficiently use the available energy resources."

This paper studies the dependence of the ratio of prismatic strength (Rb) from cube strength (R) for high-strength concrete of classes B70 ... B110. Experiments were carried on the concrete cubes with an edge of 150 mm and prisms with a base 150x150 mm and a height 600 mm. The tendency to reduce the ratio Rb / R with increasing strength of the concrete is founded. A new relationship Rb = f (R) is offered

Recommendations are given for the decision of the master plan , space planning and architectural design hotel, located in the mountainous regions of Southern Russia. Cost-effective compact centralized schemes in terms of the relief is difficult to use , so it is possible to use the blocked cells or housing related short covering pedestrian connections. In the design and orientation of the residential floors of hotels to consider an overview of the numbers of interesting species. In the design of the hotel at the foot of a steep slope is advisable to use the gallery schematic layout of residential floor gallery and orient the unfavorable shaded side of the building . When equal landscape conditions, you can use a corridor plan structure with the location of the rooms on either side. For hotels located in mountainous areas, is characterized by two main approaches to their architectural solutions : contrast harmonic landscape or merge with them.

In the field of the Museum exposition design in Russia and abroad considerable experience has accumulated. However currently we can state the absence of a comprehensive approach to create a coherent exposition system Exhibition – exhibition space. In this scientific article we formulated the concept of Space-graphic element. We have identified the structure, types and variants of use of space-graphic elements, as a special category of exposition tools in exhibition spaces. We have identified the main technical and compositional principles of space-graphic elements design. The use of those principles will allow organizing a coherent unity system Exposition – exhibition space. Concept of space-graphic elements is useful in the development of Museum and exposition activity.

Considered the questions connected with estimation of mechanical properties of steel elements of metal construction. The measurements are performed in a non-destructive method on the basis of the analysis of the characteristics of the implementation of the conical indenter in surface materials. This method allows you to get the values of all mechanical characteristics of metal. The measurement of mechanical characteristics can be made to anywhere in the design. At the same time, when large amounts of construction and large volumes of measuring works, you need to evaluate a sufficient number of measurements in a particular place. Proposed and implemented the Bayesian method of consideration of a priori information to reduce the number of dimensions and complexity of the process of receiving mechanical characteristics.
