Abstract
In offshore technology large diameter steel pipes are often used for pile foundations. Especially when used as foundation elements for offshore wind energy converters, such piles experience not only vertical, but also substantial horizontal loading. In this paper the interaction between axial and lateral forces acting on vertical steel pipe piles in sand is investigated by means of numerical modelling. A three-dimensional finite element model was developed with a non-linear elasto-plastic material law for the sand. It is found that for axial tension loads the decrease of axial pile stiffness due to horizontal loads has to be taken into account. For axial compression loads as well as for horizontal loading the interaction effects are of minor importance and can be neglected in the design.
