The Stability Problems for Bars and Plates (rus)

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

Structural Analysis of Buildings at Explosive Actions in SCAD (rus)

The article also shows how module «Direct integration of motion equations» in SCAD can be used for solving problems of explosion dynamics. In the empirical part of the study the main concern was to compare stress-strain condition of building structures at explosions, using different methods of structural analysis. The results of the study demonstrate the advantages and disadvantages of described methods, as well as the functional abilities of SCAD, when solving the problems of explosion dynamics.

The Simulation of Bond Fracture between Reinforcing Bars and concrete. Part 2. Models without taking the Bond Discontinuity into account (rus)

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

The Resistance Calculation of the Thin-Walled Cold-Formed Compressed Steel Members with Closed Cross-sections. Part 2

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.

Experimental Investigation considering the Stressed State of some Essential Constructions of Large Hydropower Buildings (rus)

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.

Dynamic Interaction between Ice and Inclined Structure (rus)

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.

The Assessment of Dynamic Behavior of Heterogeneous Systems taking into account Non-linear Viscoelastic Properties of Soil (rus)

The mathematical statement, methods and algorithms to assess the dynamic behavior of earth structures taking into account 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 structure.

The Calculation of Foundation Bed Reliability by Bearing Capacity (Shift) during Operation (rus)

New methods of foundation bed reliability 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.
