Abstract

Elements made of ultra-high performance fibre reinforced concrete (UHPFRC) are generally precast. One way to realize a continuous connection between two precast elements is to tension them together with a dry joint between them. The aim of the experimental investigation was to determine the influence of the joint geometry on the load-bearing capacity of dry joints when subjected to static loading. For this purpose shear-compression teste were carried out on 48 prismatic test specimens (600/150/75 mm). The test specimens featured a joint whereby the geometry and the angle of the joints varied. In addition, compression tests were carried out on 5 prismatic test specimens (600/150/75 mm) without joint. The results of the shear-compression tests are presented for each joint geometry in a shear-compression diagram that illustrates the load-bearing capacity of the respective dry joint.
