The problem statement related to modification of
structural design model, when stiffness parameters of the structural
undergo changes, was considered. Some data was outlined from the design
concerning design cases that occur during erection and maintenance of
and structures, when stiffness parameters of some structural members
An experimental theoretical method was
for estimating the residual load-bearing capacity of an individual
concrete beam at the operational stage according to the criteria of the
strength and durability of concrete reinforcement compressed zone of
Integrated methods of beam testing and probabilistic methods of random
variables definition were used.

The article presents the results of the
and experimental research of I-beam behavior under combined bending and
torsion. The analysis of numerical models was carried out, including
calculations in which the physical and geometrical nonlinearity was
account. Based on the calculations, the parameters of experimental
the value of the applied loads were determined.

The problem of verification of different program
suites for structural analysis has recently become an important
the construction science. One of the most extensively used benchmark
a classical geometrically nonlinear problem of deflection of the
beam of linear elastic material, under the action of external vertical
concentrated load at the free end.

The method of solving static problems of nonlinear
deformation, buckling, and postbuckling behavior of thin elastic
shells is based on the geometrically nonlinear equations of the 3D
thermoelasticity theory and use of the moment finite-element scheme. A
unified model has been created based on the
universal spatial finite element with additional variable parameters.

The paper presents a computation procedure of
physically nonlinear prismatic shells with the sealed ends. It is known

case the effect of edges on the stress-strained state of plate was
in the form of the elastic support by Winklerian model.
The paper is dedicated to improvement of plate
theory in order to take into account forces, moments and bimoments,
by nonlinear law of displacement distribution in plate cross-sections.
correlations for defining forces, moments and bimoments were given. The
developed bimoment plate theory is described
with two independent two-dimensional systems with nine equations in
The three-dimensional problem of the theory of
elasticity related to isotropic layer compression by normal load,
on a limited area, is solved by the method of initial functions (MIF).
