Abstract: Both the strength of the steel used in steel constructions and that of the reinforced concrete in the concrete constructions have increased considerably in recent years (e.g. steel S460 and concrete grades C60 to C90). Making meaningful use of such considerable increases in the material strength in composite constructions requires testing the shear-resistant connection in the composite joint between the steel and the concrete construction members.
This article summarises the knowledge from the research project "Studies on the ductility of shear connectors when using high-strength steel and high-strength concrete" gathered within the scope of the support from AiF and provides explanatory notes on the proposals developed from the findings here for construction and design.
The purpose of the series of experiments conducted was to determine the load-bearing capacity as well as the ductility of the headed stud shear connectors commonly used in high-strength concrete and to develop new shear connectors of sufficient ductility, whereby a check was also made here of the applicability of the method of evaluation used up to now for the Push-Out tests carried out according to the Eurocode 4 procedure.
Recommendations have also been developed for better characterisation of the load-bearing behaviour of shear connectors.
