Abstract
Investigations on the interaction relationships for piles under combined loading in cohesive and non-cohesive soils: Foundation piles are normally and favorably used for the transfer of vertical loads into the subsoil. However, in many fields of application piles are used simultaneously for the transfer of horizontal load. This so-called combined loading affects the vertical and horizontal load bearing behavior. In current engineering practice, these interaction effects are not taken into account. For the identification and quantification of the influences a comprehensive investigation based on the Finite Element Method was carried out. The paper in hand presents results of these investigations considering piles in non-cohesive soils regarding drained loading and piles in cohesive soils regarding undrained loading conditions. Thereby the influence of a moment and a rotational spring at the pile head is taken into account. It can be shown, that the combined loading leads to complex interaction effects which can be presented in terms of interaction diagrams. The main focus of the investigation is set on the interaction effects on ultimate loads and pile head displacements. Additionally the influence of combined loading on the pile bending moments is investigated.
