THE DEFINITION OF THE MAXIMAL DEFLECTION OF RHOMBIC PLATES WITH COMBINED BOUNDARY CONDITIONS WITH USE OF THE RELATION OF CONFORMAL RADIUSES
Коrоbkо A.V., Сhernyaev А.А.
Abstract
In the article, the problem of a cross-section bend elastic isotropic rhombic plates with combined boundary conditions (hinge a support and rigid a support) from action of the in regular intervals distributed on all area loading is considered. For estimation of the maximal deflection of plates is suggested use as the basic argument the new dimensionless characteristic of flat area - the relation internal and external of conformal radiuses.

THE COMPLETE SYSTEM OF EQUATIONS OF DYNAMIC LOADING IDEAL PLASTIC SHALLOW SHELLS OF REVOLUTION WITH TAKING INTO ACCOUNT LARGE DISPLACEMENTS
Starov A.V.
Abstract
Statement of problems of plastic deformation of ideally plastic shallow shell of revolution with hinged support and rigid fixing of edge under operation of shock loading of the big intensity in view of greater sags is considered. The complete set of the resolving equations is received, the algorithm of numerical realization of a problem on the basis of a differential-difference method is offered.

THE RESULTS OF NUMERICAL RESEARCH OF FLOATING REINFORCED CONCRETE STRUCTURES OFTHE NORTH TIDAL POWER PLANT
Novikov S.P.
Abstract
This article contains results of the numerical simulation of stress-deformed state and structure strength of floating reinforced concrete caissons of a tidal power plant. Numerical simulation was made using finite-element method. In this work a proposal to place floating caissons on unprepared underwater foundation is justified, taking into consideration, among other factors, seismic forces.

THE DETERMINATION OF UNFAVORABLE TRAJECTORY OF TORNADO MOVEMENT BY ANALOGY WITH ANALYSIS OF TRUSS
Zylev V.B., Grigoriyev N.A.
Abstract
The article discusses the definition of unfavorable trajectory of tornadoes for the elements of the middle of the through span structure of a continuous rail truss. Contains "tornado wind rose' resulting from the calculations, allowing to define stress or displacement in this element of structure at different angles of attack of tornado. Diagrams of horizontal and vertical support reactions at the moment of tornado passing are given.

DESTRUCTION OF ROCKS WITH FORMATIONOF FLAT CRACK
Sinev S.V.
Abstract
Conditions of possibility of formation of a flat crack a parallel the tosemispace from positions of the theory of cracks and mechanics of destruction are analyzed. The photo of flat cracks and the mechanism of their formation is resulted. Presumably they are formed at high-speed unloading of the rock loaded in limits I will rest-gih deformations.
