ABSTRACT
Continuous shear connectors are a recent invention, from a bridge science point of view as the first one was patented in 1985 by W. Andrä after spare of general interest in this area after the end of World War II. Therefore their development is now still hugely a focus of many researchers. At Technical University of Košice, Faculty of Civil Engineering, new geometrical characteristics of puzzle shaped steel perforated strip were designed. The strip underwent several tests, in which it was closely observed and measured, specifically the push-out tests as well as the bending tests. Both materials, steel and concrete, also underwent testing to find out their exact material characteristics for precise analysis input data along with FEM analysis later in the research. The results were analysed and are presented in this paper together with the geometrical, material and testing process description.
