As part of a research project to develop a framework for quantifying cyclic effects on piles, centrifuge model tests on single piles and pile groups in dry silica sand have been carried out at the Centre for Offshore Foundation Systems (COFS) in Perth, Australia. The piles were subjected to lateral cyclic 1-way and 2-way loading investigating the vertical and horizontal load-displacement behaviour. Strain gauges located along the pile shaft provided information about the bending behaviour. This paper considers the tests on single piles and highlights the influence of cyclic load amplitude and number of cycles on the observed response. Furthermore, the test results are compared to results from the Extended Strain Wedge Model (EWSM).
