Abstract
The very high-compressive strength of ultra-high performance fiber reinforced concrete (UHPFRC) as well as its enormous durability facilitate innovative design and construction of thin-walled and weight-optimized elements. Because the mixing and casting of UHPFRC are demanding processes, such elements are preferably precast. An auspicious construction method is joining weight- and transport-optimized UHPFRC precast elements to segmental prestressed structures such as segmental bridges, precast towers or precast poles. For the safety of these structures, the structural behavior of the joints between adjacent UHPFRC segments is fundamental. Therefore, experimental and theoretical research on the load bearing capacity of profiled dry joints of precast UHPFRC segments are carried out at the iBMB, Division of Concrete Construction of the TU Braunschweig. Using the results of slant shear tests under monotonic loading, different calculation approaches are evaluated and a modified approach is proposed.
