Abstract: A compilation of axial load test records for driven pipe piles in clay published by the American Petroleum Institute is analysed to yield new criteria for skin friction and pile scale effects. The concept is directed towards design of large offshore foundations. Peak skin friction alpha values obtained on relatively short, rigid piles are related to the degree of overconsolidation of the soil. A scale factor depends on pile length-to-diameter ratio which is a covenient simplification of pile-soil stiffness characteristics that control scale effects. Predicted capacities for offshore piles are generally greater than given by current API methods.
