Twentieth century brought a lot of forward‐moving inventions. In the field of bridges and structural engineering we could witness the birth of the first steel‐concrete composite bridges and their rapid development. In 1985, the perforated steel strips were officially introduced to the eyes of researchers by a patent from Wolfhardt Andrä. Encased in concrete to make composite bridges they have several advantages – low construction height, lower usage of steel in comparison with embedded I‐beams, etc. In practise, they are mainly used as short railway bridges due to their practicality during the construction works. Nowadays, many research groups all around the world focus on improving the above mentioned invention by tuning the geometry of the strips as well as the concrete dowels to increase its composite action. Such research is also currently running at the Technical University of Košice, Faculty of Civil Engineering, which developed five perforated steel strip types. The specimens are tested at Laboratory of Excellent Research and are modelled in software for finite element analysis (ABAQUS) to simulate the performed tests.
