Analysis of SayanoShushenskaya hydropower station dam deflected mode (rus)On the 15th February of 2012 in
SaintPetersburg State Polytechnical University (SPbSPU), the seminar
"Use SOFISTIK for advanced structure analysis and geotechnical problems
solution" took place. The main speaker was professor of SPbSPU, chief
of competence centre SOFISTIK V.V. Lalin.

METHODS  
A.V. Ulybin
The paper deals with the main
problem of reinforcement parameters determination of concrete
structures in the inspection. The basic wellknown tracks of a solution
to this problem are analyzed. The availability data of applying the
method of hardness measuring for the reinforcement class determination
is adduced.

In the present research a
nonlinear system with single degree of freedom is used for analyzing
the behavior of structures under elastoplastic deformation. The author
obtained the relationship between plasticity factor and yield strength
of structure characterized by the reduction factor K1. in the case of
earthquake loadings.

This article is written to
continue the article of recent issue of the journal. In the article we
continue realization of finite elements method algorithms and we
consider some test examples about the torsion of the thinwalled beam
having various boundary conditions on the ends.

This article illustrates a
simple method of stability analysis for elastic frames loaded with dead
and follow forces. In its undisturbed state, frame elements might
undergo not compression only but bending and torsion as well. It is
shown that for simple frames there is no necessity of program complexes
using.

ANALYSIS  
G.V. Denisov, V.V. Lalin
In this paper the
highfrequency vibrations of beam structural elements on the example of
cantilever rod are analyzed. With the help of mathematical
transformations and numerical experiments the existence of simple beam
structures mixed spectrum, formed by the discrete and continuous parts,
is shown.

In the article the variation
method of calculation of the loaded statically indeterminable
structures strengthened by increasing the section of elements and the
constructive and design model of structures modifying by installation
of additional elements is presented.

The mathematical expectations
of the crack parameters were deducted. These dependencies are inserted
into a system of building technical condition graphic models and
embedded in a methodical complex of object technical condition
evaluation taking into account visualization of defects.
