Summary

This paper is focused on the numerical modeling of steel bearing elements and their verification using experiments. Currently, for the stress-strain analysis of the elements supporting structures it is possible to use many commercial software systems, based on the finite elements method. It is important to check and compare the results of finite element analysis with the results of physical verification test, in which the real behavior of the bearing element can be observed. The results of the comparison can be used for calibration of the computational model.

The paper deals with the physical test of the steel supporting elements, whose main purpose is to obtain the material, geometry and strength characteristics of the fillet welds. The main aim was to definine numerical models for use in a finite element analysis with the commercial software ANSYS. The pressure test was performed during the experiment, wherein the total load value and the corresponding deformation of the specimens under the load was monitored. The measurements were carried out for a more detailed analysis of stresses and deformations in the weld samples using a strain-gauge and a Q100 laser device for measuring the three-dimansional deformation and infrared thermographic non-destructive testing.

The date obtained were used for the calibration of the numerical models of the test samples and they are necessary for further strain analysis of the steel supporting elements.
