One of the common types of steel‐concrete composites is the filler‐beam deck bridge with encased steel beams. Steel beams form rigid reinforcement in a longitudinal direction, while such decks are reinforced with secondary cross‐wise reinforcement in a transverse direction. Composite action between the steel and concrete sections is ensured by means of concrete stud connectors. In comparison with the composite action provided traditionally by shear stud connectors, this type of action has higher load‐bearing capacity and fatigue strength, and it is not so labour‐intensive. Great attention is paid to the development of perforated steel strips today. These are employed mainly for the achievement of composite action between a steel beam and concrete slab. To date, a variety of types of composite action have been investigated at the Civil Engineering Faculty of the Technical University of Košice; therefore, the article presented shows some of the test results from push‐out tests performed on various specimens.
