THE RESEARCH OF STRAINED SILO STATE USING CAD
Markovich A.S., Pankratova G.E.
Abstract
The repeated failures and destructions of silо constructions are the result of inconsistency of existing methods of calculation. Using CAD, present article gives the analysis of strained state of round silo as the system of plain rings and thin-walled cylindrical cover. The results of calculations are appreciated critically and compared with the results, conducted before by the authors of experimental researches of silo stress strain behavior (SSB) on the model.

THE SETTLEMENT OF THE DAY SURFACE HETEROGENEOUS IN DEPTH HALF-SPACE AS THE RESULT OF UNSPECIFIED DISTRIBUTED LOAD
Hajiyev M.о., Draz V.M.
Abstract
The technique for the calculation of day surface settlement of half-space with linear increase of deformation module in correlation with depth with the use of piecewise linear approximation of the actual load is presented in this article. The numeric examples show that half space inhomogeneity decreases distributing capacity of the foundation in depth.

DETERMINATION OF MAXIMAL BENDING OF THREE-CORNERED PLATES ON RESILIENT FOUNDATION WITH THE COMBINED SCOPE TERMS
Korobko V.I., Aktuganov A.A.
Abstract
Task of cross-bending of three-cornered plates with the combined scope terms (all possible combinations of the joint leaning and gesture-who jammings on sides) on resilient foundation, loaded with the equipartition on all area loading decides the method of interpolation on the coefficient of form (MIKF). For every combination of scope terms approximating functions are built for the count of two auxiliary coefficients, necessary for the choice of supporting decisions at the use of method of MIKF.

ON THE PROBLEM OF TWIRLED MOVEMENT OF VISCOUS LIQUID IN A PIPE
Ponomarev N.K.
Abstract
L.G. Loytsyansky put and solved system from four differential equations in private derivatives for the laminar twirled movement of viscous liquid in a pipe opening in space [1], filled with the same liquid. It found speeds of particles and pressure in the form of the ranks depending on longitudinal distance. Author considers other decision where there is a vurfovy proportion between three components of speed of a particle of liquid.

THE PERFECTION OF AN ANALYSIS METHOD OF SPATIAL SYSTEMS CONSISTING OF BOUND CLOSED CYLINDRICAL SHELLS
ShAGIVALEEV K.F., BUROV S.N.
Abstract
The way of optimization of calculation of the jointed closed cylindrical covers is offered. The essence of a method is stated on an example of the thin-walled spatial system, consisting of two closed barrel shells, one of which is subjected to internal pressure.

MODELING OF THE STRESS-STRAIN STATEOF STRENGTHENED BEAM SYSTEMS
Ubaydulloye M.N., Serazutdinov M.N.
Abstract
In the paper, the variation method of calculation of the loaded beam systems strengthened in the ways of increase of section of elements and change of the constructive and settlement scheme of structures by installation of additional elements is presented. Taking into account plastic deformations of influence of repair and mounting stresses on degree of increase of load-carrying capacity of strengthened statically indeterminable structures was researched.

MONOLITH HOLLOW FLOORS FOR DWELLING HOUSES
Glotov D.A., Loskutov I.S., Kantur O.V.
Abstract
This work summarizes monolith cellular floors design and construction within the site of a residential apartment house. The questions of engineering design, reinforcement and erection technology are considered. Attention is paid to the construction arrangement, workers training, technical and economic effectiveness of the approach compared to the similar procedures used for solid reinforced concrete floors.
