As part of the research project Building with TRUHPC, performed at the Institute for Structural Engineering at the TU Wien; and as the main topic of this master thesis, experimental investigations have been undertaken on carbon reinforced ultra high performance concrete (UHPC) specimens with integrated steel implants. Due to the combination of high performance materials and their material-specific application, it is possible to produce thin-walled and resource saving building elements. The point stress concentrations on thin-walled building elements require appropriate joining techniques. An integrated steel implant can enhance stability by allocating the stresses of the UHPC within the steel implant. Therefore, the toothed strip is introduced with the aim of transferring the compressive stresses of the UHPC to the steel implant. In the investigation, 15 specimens each with a length of 2m; a height of 20 cm, and a width of 3 cm were loaded in 5 different configurations until fracture. The 5 configurations comprised of combinations of 3 different carbon fibre reinforced polymer (CFRP) textiles and 3 different implant types. Each specimen consisted of an implant; a CFRP rod (8mm diameter), a U-shaped CFRP textile, and the UHPC. The implant types differed in their anchoring with the CFRP rod. The reinforcement tensile force of the CFRP rod, especially for two types of implant, is anchored by the bonding between the implants and the UHPC. On a third type, the tensile force of the CFRP rod is glued into the implant. The applied force; the deflection, and the crack widths were measured within the experiment. The load bearing behaviour and the stress distributions of several configurations were investigated in the numerical calculations, by varying the anchoring, and the position of the joint.
