Abstract

Pile foundations are often subject to lateral loads and axial loads. Although design methods for axial loading are well developed, lateral loading cases have attracted more attention recently following reported case histories of piles damaged during earthquakes. In this work, pile design due to lateral loading in tuff soils is considered. Pile deflections, bending moment and rotation were analyzed with OpenSeesPL program, a 3D finite element tool. OpenSeesPL is used to model the properties of the piles which are embedded in tuff and laterally load tested in Izmir. The displacement calculated by OpenSeesPL of 2.25mm is close to the measured 2.5mm. In this study, influence of pile length was investigated. From the results, it was observed that as the pile length increased from 6m to 20.5m, the movement, displacement and the rotation of the pile has decreased. In addition, with the same program, lateral displacement of a single pile in sandy and clayey soil layers were also analyzed with the results summarized. In all types of soils, as the pile length has decreased, the pile displacement has increased.

Behaviour of Laterally Loaded Piles

Pile foundations are often subject to lateral loads and axial loads.
