Definition of reliability at the the non-centrally compressed rod in conditions of elastic deformation at the limited statistical information
The Vologda state technical university
Abstract. In article the technique of definition of points of the appendix of forces the non-centrally compressed rod with various types of sections, special cases of model of a limiting condition are considered. In article the new technique of definition of reliability of similar steel cores in conditions of elastic deformation is offered at absence of the full and exact statistical information, the numerical example is given.
Keywords: the non-centrally compressed rod, the elastic deformation, limited statistical the information, reliability, a method of opportunities.

Optimization membrane environments with greater вырезом on the oval plan
Department of theoretical and applied mechanics,Donbas National Academy of Civil Engineering and Architecture
Abstract. In clause application of methods of optimization to membrane to an environment of a covering of stadium on the oval plan with greater aperture is described. Optimization it was spent on dimensionless parameter and the area of cross-section section of an internal basic contour (rigidity on a stretching-compression) for criterion function of t-thickness of a membrane.
Keywords: steel membrane an environment of the constant thickness, the is intense-deformed condition, a technique of the optimization, the approached design procedure of an environment.

The account of loads and effects in mechanical calculations of H-frame structure of switch-gears
Donbas National Academy of Civil Engineering and Architecture
Abstract. The article is dedicated to questions of the account dynamic influence when designing H-frame structure of switch-gears. Comparative analysis of results of dynamic calculations under the simplified and volumetric calculated schemes is executed. The results of the calculation of influence of dynamic component for different variant of the constructive scheme and of joins are analyzed. Comparative analysis of results of dynamic calculations of effect of a short-circuit for different variant of the constructive scheme is executed.
Keywords: h-frame structure, dynamic influences, tense-deformed condition, effect of a short-circuit.
