characteristics. These values can be obtained in two ways: experimental measurements in a specialized
laboratory or computer modelling by FEM. Experimental measurements are significantly more expensive
and more time-consuming. However, for proper tuning, a computer model is very valuable and can provide
the necessary verification by experiment. In the cooperating workplaces of GIG Katowice, VSB-Technical
University of Ostrava and the Institute of Geonics ASCR this verification was successful. The present
article discusses the conditions and results of this verification for static problems. The output is a tuned
computer model, which may be used for other calculations to obtain the load-bearing capacity of other
types of steel arch supports. Changes in other parameters such as the material properties of steel, size
torques, friction coefficient values etc. can be determined relatively quickly by changing the properties
of the investigated steel arch supports.Workplace Institute of Geonics Contact Lucie Gurková, lucie.gurkova@ugn.cas.cz, Tel.: 596 979 354 Year of Publishing 2018 Electronic address http://archiwum.img-pan.krakow.pl/index.php/AMS/article/view/952
