Title:
Abstract:	Im Beitrag wird ein neues Berechnungsverfahren zur Ermittlung des Tragverhaltens von axial-zyklisch belasteten Pfählen vorgestellt, mit dem die Nachweise im Grenzzustand der Tragfähigkeit (GZ 1B) und im Grenzzustand der Gebrauchstauglichkeit (GZ 2) geführt werden können. Das Verfahren berücksichtigt sowohl die Abnahme der Mantelreibung mit steigender Zyklenanzahl infolge der Verdichtung des den Pfahl umgebenden Bodens unter zyklischer Scherung als auch die resultierenden axialen Pfahlverformungen infolge zyklischer Verdichtung und infolge der Akkumulation von Schubverzerrungen. A simple procedure to analyse piles under cyclic axial loading. The following paper introduces a newly developed design procedure to calculate the bearing capacity of cyclic axial loaded piles for both the ultimate limit state GZ 1B and the serviceability limit state GZ 2. The procedure incorporates the degradation of shaft friction due to compaction of the surrounding soil under cyclic shear as well as the resulting axial pile deformation due to cyclic compaction and accumulation of cyclic shear strain.
