"Effective and affordable sorbents produced from natural organic raw materials and waste products of agricultural and livestock origin, because these sorbents are part of existing ecosystems and, therefore, best meet environmental requirements, in order to ensure the rational nature management and preservation of consumer properties of water resources. For the solution of actual problems, such as the removal of oil and oil products from water surface, as sorbents was investigated by the waste processing of leather and agricultural industries: wool (sheep and goat) and feather (chicken and waterfowl). It is established that application of organic and mineral acids at certain concentrations , for treatment of wastes from the processing of wool allows to obtain sorbents directional spectrum for removal of oil products (such as diesel gas oil and engine oil) and oil from water. The modifiers of wool and feathers obtained after the chemical treatment, was used to study the sorption of oil and oil products from water surface. It was determined by sorption characteristics of the modified sorbents, such as oil capacity and moisture absorption. The kinetics of sorption–desorption of oil, which showed that the greatest degree of absorption is observed for the first 10-15 minutes. It is found that wastes from goat and sheep wool have a 90% holding capacity that persists in time. It was revealed the effect of temperature on oil absorption capacity of the sorbent and the calculation of heat of adsorption. The temperature increase leads to a reduction of the capacity of emulsified oil, reducing the degree of purification by 15-30%."

The results of numeral experiment you show that to split beamless slabs on finite elements without the use of absolutely rigid bodies true the following statement: with the increase of the size of the finite element area is required for calculating the reference valve As.2 is reduced. In all considered grids with the area of the transition from AЖТ to the plate in the form of triangles observed the effect of the increase required for the calculation of rebar on the distance from the face of the column, which in our opinion is illogical and difficult to explain. The creation of transition zones with finite elements having dimensions close to the size of the AЖТ leads to low results and can not be considered a good solution. The transition from AЖТ to the plate with a crushing grid to a size equal to half of the column cross-section gives results almost identical with the variant of splitting the plate into finite elements of size equal to the cross section of the column without the use of absolute rigid bodies. Given the complexity of the representation of junctions of columns with plate type 3хАЖТ practical importance is a variant of the partitioning plates (in the node pair with the column) on a square (close to square) finite elements, whose dimensions are equal to the cross section of the column.

Construction of three-dimensional structures faces the need to cover the hard concrete layer with lightweight insulation and waterproof carpet. This combination of materials with different mechanical and physical properties requires the creation of methods for determining the stress-strain state of elastic composite layer lying on absolutely solid. According to these criteria the general solution of elasticity theory problem for each layer has been calculated. The system of differential equations is solved. A homogeneous solution can be used to study various problems of stress state in a layer. Formation of the problem of infinitely extending beamless surface has been drawn as an example. These solutions can be used in studding various problems of stress state layer. The solutions of engineering problems require the definition of complex roots of transcendental characteristic equation. In this paper, the roots were determined by Newton`s method. The obtained roots of the characteristic equation determine the stress and displacements in each point of a composite layer.

Preliminary tensile steel bars, stacked in the tension zone of reinforced concrete structures, allows significant savings. Research carried out in recent decades, many scientists in the Russian Federation and abroad, show that the reinforcement in the compressed zone, subjected to preliminary compression, and is able to give a significant economic impact. This question has not been investigated. There is no justification for such a common attachment to the transverse reinforcement, especially when you consider that they work only in the short period of hardening concrete (28 days). It may be that there are extra expenses expensive metal, time and labor. These reasons impel to consider in order to create a mathematical model of this problem from the standpoint of structural mechanics and its decision.

The calculation of multi-storey reinforced concrete frame building, consisting of apartments, offices and underground parking, against progressive collapse is presented in the paper. Two different ways of simulation of reinforced concrete building against progressive collapse are suggested, needed for estimation of survivability of building structures. The technique, which allows to carry out the stability of reinforced concrete structure to resist progressive collapse, is presented. This method is based on a nonlinear analysis of framed structures under the special load combination and includes dead and live loads, implying that the loading process modeling is fulfilled on the basis of the adjusted step method. The last one is of great importance for simulation of the processes in the whole life cycle of structures. The obtained results show that the offered strength calculation method of the framed structure against progressive collapse considers both geometric and material nonlinearity and also allows to assess survivability of the construction under conditions of emergency events and its stability to resist against progressive collapse. The step method of solving nonlinear problems, applied for modeling of collapse process, is shown to be more appropriate for these cases. We conclude that applying the proposed method of calculation results in more economic use of materials, giving evidence of its effectiveness.

To the design of roofs and ceilings of modern buildings have high requirements on the bearing capacity and the architectural expression. The article considers a constructive solution to the coating of the building with light cross farms. The spatial work of such coverage is provided by bonds arranged in two directions farms, perceiving external load. The increase in hardness of the coating leads to a decrease in effort in some parts of the coverage. This allows the use of thin-walled steel profiles with less consumption of steel to cover in comparison with splenomegalie rolling beams. It is proposed to use various options of the arrangement of spatial units: 18x18, 24x24, 24х18, etc. the Overall structural stability is ensured by the fact that the coverage is created a few of these spatial blocks around the perimeter. The calculations allowed us to obtain the optimal size and number of cells on which it is conditionally possible to divide the disk coating.
