ABSTRACT

The paper presents an experimental verification of shear connection between steel and concrete part of a composite beam. One of the common types of shear connection is the method of rolled girders encased in a concrete slab. The combination of such method and pcb (precast composite beam) technology is called pcb-W (precast composite beam – coupled in web) technology which has been developing since 2003 in Germany. The longitudinal shear force is transformed by composite dowels instead of headed studs. The standard push-out tests according to EC4 have been performed at the Brno University of Technology to verify the behavior of the composite connection and to investigate the possibility of application of steel fiber reinforced concrete for such technology. The reason of this research is to lower the area of reinforcement bars in composite dowels and make the process less laborious.
