Based on equilibrium equations of a shell element for the membrane theory and continuity equations of its middle surface to derive relationships between the components of the surface load in the shells of revolution. These relations are convenient to go to special cases of shells of revolution in their original ax symmetric subcritical state.

  Given the task of calculating the stresses in the radiation-thermal plant screen. This design, also known as «dry protection» is intended to reduce the effects of radiation and heat, generated in the reactor. A significant redistribution of stresses due to changes in elastic modulus due to the above effects.

Keywords: thermal loading, loading of radiation, the calculation of protection for accident-mode for trouble

In this paper, on the example of spatial mechanical and mathematical model of a residential building in an emergency Belovo Kemerovo area the opportunity to assess the actual condition of buildings and structures on the basis of geodetic observations and a series of numerical experiments. The obtained data were used to develop the methodology for assessing the technical condition of buildings and structures on the basis of monitoring.

Considered sharing FEM and BEM for the calculation of the dynamic behavior of the surface structures on the basis of a multilayer. To implement the BEM in calculating base proposed analytical method is effective for an arbitrary number of layers and the relations of their parameters. Given system approximating functions in the interface methods and proposed numerical integration formulas on the mating elements.

In the framework of the nonlinear buckling considered the problem of determining the critical pressure, distributed over the face of the cylindrical shell. Buckling criterion is the appearance of positive acceleration directed along the normal to the middle surface of the shell. Numerical solution of the system implemented in MathCAD. Given its comparative analysis with the known solution formula Papkovich.

Energy method in the form of Tymoshenko Ritz-solved the problem of stability of a circular cylindrical shell under uniform axial compression. Considered axisymmetric shape shell buckling during buckling and axisymmetric initial state, as well as axisymmetric subcritical state during compression. The resulting solution is exactly consistent with the decision of the Lorentz-Tymoshenko known as a classic.
