Title:
Abstract:	Die Beton-Stahlrohrsteckverbindung wird in dieser Arbeit für die Anwendung bei hybriden Mastkonstruktionen aus der Stahlrohrsteckverbindung weiterentwickelt. Die maßgebende Biegebeanspruchung der Maste wird dabei vom Stahlrohr mit Schubrippen über die Mörtelfuge in das darunterliegende Schleuderbetonrohr eingeleitet. Der Kraftfluss in der Verbindung ändert sich fortlaufend mit der Lastzunahme und wird entscheidend vom Verformungsverhalten der Rohre beeinflusst. Das Trag- und Verformungsverhalten der neuen Verbindung wird in diesem Beitrag anhand zweier durchgeführter Großversuche und begleitender FEM-Simulationen untersucht. Des Weiteren wird anhand zweier variierter Parameter, der Position der Schubrippen sowie einer Steckverbindung ohne Schubrippen der Einfluss auf das Trag- und Verformungsverhalten ermittelt und diskutiert. Investigation of the load-bearing behaviour of connections of the hybrid mast construction - Large-scale tests and FEM-simulations The grouted concrete-steel slip joint is developed in this paper for the application in hybrid mast constructions from the grouted steel slip joint. The decisive bending stress of the masts is transferred from the steel pipe with shear keys via the grout joint into the spun concrete pole below. The force flow in the connection changes continuously with the increase in load and is decisively influenced by the deformation behaviour of the poles. The load-bearing and deformation behaviour of the new joint is investigated in this paper by means of two large-scale tests and accompanying FEM simulations. Furthermore, the influence on the load-bearing and deformation behaviour is determined and discussed on the basis of two varied parameters, the position of the shear keys and a grouted slip joint without shear keys.
