The non-linear springs' properties are therefore linked to suction bucket diameter, friction angle and vertical overburden pressure. Lastly...

... friction angle) according to the recommendations of the American Petroleum Institute (API). The p-y-curves published in the API-guidelines (API 2000) are based on model tests with pile diameters of 0.3 m - 0.64 m (Reese et al. 1974, Matlock 1970, O'Neill & Murchison 1983). Pile diameters up to 8 m...

..., the pull-out load of the pile was reduced by 36% in dense sand and to the self-weight of the pile in loose sand. Back-calculation reveals a correlation between the lower tensile capacity of the pile and reduced interface friction angles during the application of vibration indicating that such a method may...
