his paper presents initial results from geotechnical centrifuge experiments on squat gravity caissons/monopiles under cyclic rotational loading in soft clay under undrained conditions. These experiments were conducted in the 150g-ton centrifuge at Rensselaer Polytechnic Institute. In total three monopiles with length to diameter aspect ratios of two were tested. Though this aspect ratio is a bit atypical it could be a reasonable option for offshore renewable hydrokinetic systems or a component in tripod or tetrapod wind tower foundation systems. Results are focused on behavior arising from an unrestricted vertical coordinate, allowing self-weight to contribute to combined loading, and the effect of load eccentricity and depth of rotation on rotational resistance.
