STORM-INDUCED CYCLIC LOADING OF ANCHOR PILES IN CLAY

1

TL;DRAbstract

The response of anchor piles in clay under sustained, storm- induced cyclic loading has been investigated in a series of rapid static and cyclic model pile load tests supplemented by static and cyclic laboratory tests used to define the properties of the reconstituted foundation soil. These experimental results are evaluated and compared to similar data from the literature in order to provide insight with regard to some critical design aspects, namely the degradation of cyclic stiffness, the accumulation of permanent displacements and the ultimate pile capacity under combined static cyclic pullout loads. Drainage conditions at the pile-soil interface, as well as, applied load magnitudes and number of cycles are identified as the main factors which control the pile response. The effect of these factors is described by simple analytical expressions and charts that can be used for the design of anchor piles in offshore environment.
