Abstract: The outstanding properties of ultra-high performance fibre reinforced concrete (UHPFRC) promote innovative applications. The aim of the experimental program presented in this paper is to determine the performance in terms of capacity and ductility of the headed shear stud connectors in UHPFRC joints using a single side push-out test. A total of 5 specimens were tested with various parameters including, concrete type, haunches, stud length. The specimen performance related to the concrete type is considered. Test results showed that the failure mode of composite girder with UHPFRC connection is always by stud fracture through the weld collar. Compared with ordinary concrete, using shear connectors in UHPFRC leads to an increase in the load carrying capacity while presenting high ductility
