MODELING SPATIAL CRACKS IN CONCRETE STRUCTURES IN TORSION BENDING
Abstract
The article discusses modeling of spatial cracked concrete structure, working in bending and torsion. Variants of surfaces modeling spatial crack are right helicoid,bicubic Coons sur- face, and bilinear surface. The analysis of these surfaces gave a possibility to choice the most suitable simulation

CALCULATION OF REINFORCED CONCRETE BEAM RELIABILITY ON THE CRACK LENGTH CRITERION
Abstract
The article describes the methods of calculation of reinforced concrete beams reliability at operation stage by the concrete crack length criterion. The offered methods differ in the fullness of statistical data about controlling parameters in mathematical design model. The numerical examples of reliability calculation are given. The article also illustrates the applica- tion of evidence theory for evaluation of mathematical expected value of reliability in the presence of statistical information in the form of a subset of intervals.

STRESS AND DEFORMED STATE OF TWO-LAYERED ANISOTROPIC FOUNDATION IN THE ABSENCE OF FRICTION BETWEEN THE LAYERS
Abstract
The technique of determining displacements and stresses in anisotropic two-layer basis, in the absence of friction between the layers, under the influence of normal surface load is given. The solution is based on the equations of the plane problem of elasticity theory. The diagrams of change of stresses plotted on the characteristics of the material layers are presented.

THE NATURAL FREQUENCY OF THE COMPOSITE LAMINATED ROD
Abstract
Oscillations in the multi-layer composite bodies are studied. Natural vibrations of a reinforced many-layered rod are researched. For determination of the characteristics of multi- layered rods and for clarify of the role of some of their parameters, a rod of the rectangular cross section and the most simple forms of vibrations were considered. The results of numerical calculations are compared with experimental data

ROD VIBRATIONS CONSIDERING NON-LOCAL DAMPING
Abstract
In this paper, an impact made by non-local damping on rod vibrations under the periodic and stochastic load is considered. The relationship between the non-local damping characteris- tics and the dynamic behavior of the rod is analyzed. The solution is obtained using the Galerkinmethod.

INFLUENCE OF THE THERMAL MODE OF THE PACIFIC OCEAN ON RAINFALL IN HYDROGRAPHIC DEMARCATION OF THE MANABA (ECUADOR)
Abstract
In the article, results of the analysis of influence of the thermal mode of the Pacific Ocean on volumes of loss of rainfall in hydrographic demarcation of Manabi (Ecuador) for 51 annual periods which have shown that change of an amount of precipitation doesn't depend on air temperature in the territory of demarcation are stated, and depends on the water temperature of the Pacific Ocean.

ANALYSIS OF UNSTEADY LIQUID MOTION IN CIRCULAR CYLINDRICAL SHELLS FOR COMPLEX SCHEME INCLUDING SEVERAL RINGS
Abstract
He analysis of parameters of the unsteady fluid motion for complex circuits containing several circular rings is given in a paper. The author has set the task to carry out the calcula- tions of long hydraulic circuits with the presence of several circular rings included in the ge- ometry of the outline with different diameters of the pipelines with the specified estimated consumer spending with many points of branching pipelines. Thermal circuit of Nizhniy Novgorod city is adopted in the enlarged view.
