ACCELERATED LEARNING IN HIGHER EDUCATION AS A CONDITION OF A CONTINUOUS AND HIGHER EDUCATION: PRINCIPLES AND APPROACHES
Balykhin G.A., Balykhin M.G.
Abstract
The process of accelerated learning is differ than the traditional process: the teacher (mentor - a teacher, lecturer, instructor) not only teaches but organizes the educational process in which the student has to learn himself, teaching the same acts as the management of a specific process. Exploring the principles, approaches, continuing education and pedagogical way accelerated learning techniques, the authors argue: by what kind of creative and imaginative facilities teacher will create the conditions, mechanisms for the learning process where the student learns and acts professionally, actively masters of experimental and innovative educational activities at the university.

CABLE-STAYED STRUCTURES
Krivoshapko S.N.
Abstract
Cable-stayed structures are simple in assembling, light in weight, safe in maintenance, and sometimes possess the architectural expressiveness. The well-known structures and build- ings of all types which had practical importance and novelty, were marked by the rewards of professional association or were passed into the top lists of journals are presented in the paper. The author offered his own classification of cable-stayed structures containing nine types of considered structures

ANALYSIS OF THE STRESS CONCENTRATION IN THIN-WALLED ELEMENTS OF STRUCTURES WITH LOCAL IN-DEPTH
Yakupov S.N., Nasibullin T.R.
Abstract
One must use a three-dimensional approach to determine the concentration of stresses in thin-walled elements of structures with local deepenings or defects. The stress concentration is analyzed for shells and panels with local deepenings. The authors investigated the effect of the finite element partition of a panel on the results and the concentration of the stress for the pan- els made from the different type of material: the model of Hooke and the model of Neo-Hooke (rubber-like material).

A METHOD OF DETERMINATION OF STRESS-STRAIN STATE OF 3D STRUCTURES OF COMPLEX FORM
Khayrullin F.S., Sahbiev O.M.
Abstract
In the article, the variation method of definition of the tense-deformed condition of three-dimensional constructions is offered which based on using of functions with final carriers of any extent of approximation that allows making calculations of constructions with curvilinear boundary surfaces, and also compounding constructions

INVESTIGATION OF THE INFLUENCE OF AUSTENITIC STEEL SURFACING ON CRACK OPENING OF PEARLITIC STEEL PIPELINE Du850
Kuzmin D.A.
Abstract
A pipeline with surfacing is investigated. It is shown what happens to the base metal of the pipeline if it is clad with surfacing under normal operating conditions and the obtained stresses and strains are investigated. The influence of surfacing on the through crack in the pipeline was investigated and its influence on a crack opening was also studied

STRIP TENSION UNDER CONDITIONS OF ONE - AND TWO-ZONAL ROLLING
Kokhan L.S., Morozov Y.B., Slavgorodskaya Y.B.
Abstract
Power parameters of free rolling of a strip without tension are compared to rolling with one site of lag and an advancing on the deformation center. Dependences of a choice of limit values of back and forward tension are given

DETERMINATION OF RESIDUAL STRESSES BY ETCHING CANTILEVERED SAMPLE
Belousov Y.V.
Abstract
The article describes experimental-theoretical method of determining technological sur- face residual stresses with application of layer-by-layer etching of the cantilever-fixed sample. The developed method of calculation of residual stresses in the surface layers of the material. It is shown that the proposed calculation method is more sensitive compared to the known and practically coincides with the classic, which uses sample with two simply supported edges.

THE EVOLUTION OF RESIDIAL RESOURCE OF THE MAIN BUILDING R-1 OF "VOLTAYR-PROM" AS A COMPLEX STRUCTURE
Suhina K.N., Pshenichkinа V.A.
Abstract
In this paper, we have proposed a method for determining the law of variation of the resource and the prediction of the service life of the existing buildings, we have modeled the diagram of the main supporting structures of the coating in the form of a complex redundant system with a permanent source, the results of the main numerical characteristics of reliability and determined the mean time between failures of the system "post farm - truss".

PHYSIC-MECHANICAL CHARACTERIZATION OF THE CLAYEY SOILS OF ISSABA DEPRESSION IN THE SOUTH-EAST OF BENIN
AGBELELE K.J., Gerard G.A., Abalo P.K., Gerard D.
Abstract
The instability of soils due to the swelling phenomenon is among others at the origin of enormous damages in civil engineering works, such the deformations, the cracking, the tear- ing, the wear of the rotation surface and the destruction of the foundations observed at the infrastructures level (housing, socio-community centers, covered road or not). This phenome- non is a very complex and particularly threatening situation for the different construction projects, in a lot of regions of the world where these types of soilsare met and at the level of which we note premature damages of the works. It urges then to make specific arrangements during the execution of infrastructures. The phenomenon described above is also present in Benin mainly in the depression of Lama.

SETTLEMENT DEFINITION OF PHYSICAL-AND-MECHANICAL CHARACTERISTICS OF ROCK FOUNDATIONS OF THE SECTION № 28 OF THE CONCRETE DAM OF BOGUCHANSKAYA HPS
Shestopalov P.V.
Abstract
In accordance with the author method of calculation of the physical-and-mechanical characteristics of the foundations of concrete structures based on finite element models, computational studies of deformability and strength characteristics of rock foundation of section №28 of Boguchanskaya HPS concrete dam based on foundation subsidence field data (including its near-contact zones) were performed
