positive definiteness of the potential energy functional is studied.
transition from the three-dimensional stability problem to the
problems for bars and plates is executed. Concepts
of displacements through the section of bar and plate thickness are
geometrically nonlinear problems.

The comparison between the obtained numerical
results and experimental data has been presented and discussed. The
of the article is devoted to the models taking into account the
of the connection. The second part is concerned with the models without
explicitly taking into account discontinuities.

The article investigates the mechanisms of corrosion processes in
reinforced concrete in condition of sulfate corrosion. The paper
calculation model and the method that predict the durability of
structures. Experimental studies on the interaction of the
concrete samples with
aggressive sulfate medium are conducted.

The theoretical analysis
was oriented to determine the resistance of mentioned members according to
European and Slovak standards, while the experimental investigation was to
verify the theoretical results and to investigate the behavior of the
above-mentioned members during the loading process. Part 2 is focused on
the numerical analysis of the achieved results, as well as on 3D modeling and
simulation of the experimental tests.

The research was carried
out by the method of photoelasticity "freezing" of deformations using
the ability of epoxide polymers to maintain the constant optical anisotropy,
caused with loading of the model, after unloading. The results allowed to
specify the stress distribution in significant critical structural sections, to
evaluate the reliability of estimates of stress concentrations by the holes in
arches, fulfilled by finite-element method.

The numerical investigation of the problem based on
the program ANSYS is used in this paper. The following topics are considered:
a) what is the difference of maximum ice loads in 3D and 2D solutions; b) how
does dynamicity of the ice/structure interaction process influence on the
loads; c) how does the ice load depend on the main factors – ice strength, ice
thickness and the structural slope angle.

heterogeneous specific features of a structure, linear, non-linear-elastic,
non-linear-viscoelastic properties of soil under different dynamic effects are
given. The result of a dynamic calculation is the study of unsteady forced
oscillations of a number of earth dams taking into consideration non-linear
viscoelastic properties of soil and heterogeneous specific features of a

calculations by the criterion of the shift when the base is under the influence
of horizontal (shifting) forces are made. Initial statistical information is
limited. Random variables in the calculation model are
described by distribution functions of possibility (from the theory of
possibility), distribution functions received from Chebyshev's inequality;
combination of functions.
