Methods of Boundary and Finite Elements in Structural Mechanics (rus)From 28th till 30th September the traditional 24th Internationalconference "Mathematical Modeling in Mechanics of Solids and Constructions. Methods of Boundary and Finite Elements" (BEM-FEM-2011) took place. The organizer of this event was Saint-Petersburg Research House. Every year the conference attracts key specialists in structural mechanics and shipbuilding mechanics.

paper considers the influence of offsetting
and axes fractures of
wall panels in the process of its installation into large-panel
Comparative analysis of design schemes that takes into account
of errors in installation is done. Conclusions
about need to consider installation errors (caused by a deviation from
of vertical structures) in design model were made, including
calculation in the

Generalized Glowrt-Den-Gartog criterion taking
account mode shape and wind speed instability all along height is
CFX program for determination the aero dynamical coefficients is used.
Functions for approximation and interpolation of aero dynamical
functions of wind angle of attack are offered. The use of obtained
results for calculation of
Glowrt-Den-Gartog criterion and determination of galloping fluctuation
possibility are shown.
In the present research
a nonlinear dynamic analysis of the multi degree of freedom system
with nonlinear single degree of freedom system are used for analyzing
behavior of structures under plastoelastic deformation. The validity of
application of a nonlinear single degree of freedom system is analyzed
comparing the results obtained by single degree of freedom system with
results from nonlinear dynamic analysis of the multi degree of freedom

Using the Bubnov-Galerkin method, the system of
nonlinear ordinary integro-differential equations in partial
obtained. The numerical method based on the quadrature rules was used
solving it. The algorithm for the computer solving was
obtained. The computer steadiness modeling of the analyzed shells was
held, under varying its physical, mechanical and geometrical parameters.

The aim of this work is analysis of strength
deformability of floor by two different methods: analytical calculation
calculation by finite element method using SCAD. It was shown that the
element calculation is more precise and also it allows to use armature
lesser diameter that decreases the cost of the floor.
