A necessary procedure for the evaluation of reliability and durability of supporting steel structures is an identification of critical points with the stress contractors because the critical areas are decisive with regard to location of supporting structure damage or loss of functionality. The identification of critical points can be performed by means of various methods. The full-field optical method can be found among the most often used ones. In this article there is presented an application of the transmission photoelasticimetry at the full-field stress analysis of the selected construction elements.
