SYSTEM FOR THE STRENGTH ANALYSIS OF THE BEARING STRUCTURES OF THE SPORTS FACILITY COVERING
Pages 85 - 90
In the article, the authors consider a computational system composed of standard software
packages ANSYS and MathCAD employed to evaluate the current technical condition of the bearing
structures of the sports facility covering based on the comparison of the calculation results with the
those specifi ed in the normative and technical documentation, by taking account of the cross sections
of the bearing structures weakened by corrosion-related processes.
MathCAD computational modules take account of all peculiarities of the cross sections, namely,
their stiffness-related properties, in order to automate the calculation of the geometrical characteristics
of the covering segments, to consider changes in the geometric dimensions of a cross
section due to reduction of the inner side of the wall section thickness as a result of steel corrosion.
Corrosion processes were subjected to statistical processing to determine the interactions of factors,
as well as further clustering of elements based on the velocity of corrosion-related processes.
The software programme uses geometric dimensions of cross sections as the input data designated
for the calculation of the stiffness of elements exposed to corrosion.
Final results of the calculation of the stiffness of rods are placed into a text fi le to be supplied
into the programme responsible for the static analysis of the covering in the ANSYS medium.
The results of the static analysis of the rod structure of the covering are transported from the ANSYS
programme into the modules of the MathCAD programme as text fi les. Over there, they are used
to analyze the stress state of the bearing elements. This fi nal calculation is the third step of the analysis,
and it is performed to evaluate the operational integrity of the covering on the basis of the fi rst and
second groups of criteria applied to the limit states according to Construction Rules and Regulations.
