The object of the research is porous ceramic blocks relatively new building material, which appeared in the 80s of the last century. The article examines the characteristics of this material. Highlighted its advantages and disadvantages. Also it found that from porous ceramics as the material of the carrier is allowed to cock the building height of floors 9, inclusive, and if it is used as a self-supporting material or non-structural, that its application is almost unlimited. Technology of using this material is significantly different from the usual brick, since the solution is placed on horizontal joints only, and the vertical seams do not need it due to the fact that the end faces of blocks connected in tongue and groove. The solution is used "warm", since joints are cold bridges and through them to originate the biggest heat loss. Transportation porous blocks is carried on pallets to wrap the package in the film. Keep material as possible in the transport position and in the stack. The study concluded that that "warm" ceramic is a promising replacement for the traditional bricks, as almost all the characteristics except the fragility and frost, it is ahead of him. Also one of the major advantages is the thermal conductivity of the material is several times lower than that of a brick, in accordance with the permitted walling of "warm" without ceramic heater that increases the life of the building and reduce construction costs.

Concrete structures are one of the basic materials in construction. Together with the concrete is usually used metal armature. But the steel reinforcement has a number of shortcomings and high cost. New materials, such as composite rebar, appear on the trading floor and remove the shortcomings, as well as reduce the cost of construction. This article describes a polymer reinforcement. Also, the basic properties of composite and metal fittings. Compiled table diameters of compliance with full-strength replacement. This is complemented by a comparative analysis of the characteristics of valves, namely by comparing two kinds of cores for tensile strength, elastic modulus, density, diameter, length, corrosion resistance, cost, thermal conductivity, and the convenience of shipping and installation. Also, are the main advantages and disadvantages of composite reinforcement. On this basis, indicated the main lines of the new building material. For example, the foundation slab, measuring 10 by 10 meters, is considered justification for the use of composite reinforcement with economic and engineering viewpoints.

The article describes the main types of steel wire ropes, their structure, the materials which they are made of and modern ways to increase their operating characteristics. There are also explores the forces occurring in a double lay rope with organic core, produced the selection of the rope based on forces acting on the polyspast. Taking into account the structure of the steel rope, is calculated the maximum equivalent tension in it, and this value is compared with the maximum allowable tension value in accordance with the labeling group of rope. The calculation scheme of the rope is a rod (the core) working on tension, and a spring (strands) working on torsion, bend and shear, the axes of which is coincide with the axis of the rod. We made calculations with different values of the applied load and came to the conclusion that in the rope occur tensions longer than tensions given in the GOSTs. Therefore it is necessary to increase the strength of the rope without changing the diameter of its strands in order that the rope does not lose its flexibility. It is one of the main directions in the study of the ropes nowadays.

Modern development in urban areas of individual residential development in Russia shows insufficient regulation by the town planning regulations. Balanced development, as a rule, is justified by the initiative of customers or by a successful project solution. The established limit parameters do not form the development of territories, which subsequently adversely affects the aesthetics of development and urban interior, hinders the improvement and maintenance of territories and often puts landowners in unequal conditions. The envisaged parameters of permitted construction do not reflect an integrated approach to the formation of buildings in different urban areas. The purpose of the study is to identify planning methods that affect the development of territories, and to develop approaches that allow for the targeted regulation of building parameters. The article presents an overview of the existing limiting parameters of permitted construction using the example of individual Russian cities. The performed work shows the need to improve the established limit parameters of permitted construction for low-rise residential development.

At present, energy saving tasks are the most acute in modern construction. More than 25% of the total heat losses of the building falls on the foundation, this is a significant figure. Also, it should be noted that in the water-saturated clay soils, widespread in the Perm region, arise the forces of frost heaving. It is the reason for the deformation of the foundation. During the foundation works, it is necessary to take qualitative and effective measures to reduce the heat losses, which simultaneously solve the problem of reducing the impact of the heaving. The article presents recommendations for reducing the heat losses through the foundation part of the building, based on the thermal imaging survey. The design solutions for heat insulation of the foundation are considered taking into account the calculation of the thermal fields on the «Elcut» program and the values of the temperature and heat fluxes in the foundation body are revealed. Based on the results of the calculations, there was performed the comparison of the heat insulation options in terms of the energy efficiency and reducing of the frost heaving forces.

In this article, problems of restoring the bearing capacity of brick walls in buildings that are objects of cultural heritage are considered. An analysis was made of various ways to solve these problems. In particular, traditional and modern methods of reinforcing brickwork are considered. The main disadvantages of restoring the bearing capacity of brick walls with traditional methods, such as the device of the cage, the injection of special solutions and partial or complete replacement of the masonry elements, were revealed. The main problems of the above methods are the impossibility of combining the effective reinforcement of the bearing capacity with the preservation of the external appearance of the building and the minimum labor costs. As an alternative, modern ways of reinforcing brickwork were considered: a patented technology for the use of reinforcing bars and techniques for strengthening the horizontal seam.
