Generally, piles are slender structural elements that transfer the vertical and horizontal structural loads to stiffer soil deposits or bedrock. In particular, the axial load transfer is through the pile shaft and/or via the pile end. These piles are defined as friction or end bearing piles when one of the two previously mentioned load transfers are negligible with respect to one another. This paper considers the influence of the pile head restraint, as well as lateral soil support, on the stability of axially loaded piles. This is commonly referred to as pile buckling.
