Lateral Response of Fixed‐Head Pile

Quantitative estimates of the various soil-pile parameters on lateral pile head displacement, rotation and moment coefficients are presented in dimensionless terms through graphs. The results provide guidelines to predict the lateral response of free-head piles. The illustrative example highlights the utility of the results. These results can also be used to predict the responses of partially restrained head piles.

Lateral Pile Response During Earthquakes

A nonlinear method for seismic soil-pile-structure interaction is presented. Primary features of the proposed method include a consistent approach to determine seismic p-y relationships and a liquefaction model that is suited to pore pressure evaluation for earthquake-type irregular loadings. The seismic- p-y relationships are determined from nonlinear stress-strain relations of soils, and include soil nonlinearity as well as pore pressure buildup effects around a pile. The performance and validity of the method were evaluated through an analysis of shaking table test on model soil-pile-structure systems. Using the proposed method, seismic response characteristics of an idealized offshore pile-supported structure at a sand site were analyzed. Results indicated that liquefaction as well as pore pressure bulidup around a pile can have a large impact on the response of pile-supported structures.

Analysis of lateral response of non-uniform section piles : Poulos, H G; Adler, M A University of Sydney School of Civil Engineering research report R330, Oct 1978, 34P

Two alternative methods of analysing the lateral response of a pile of non-uniform section in an elasto-plastic soil mass are presented. The first utilises a finite element formulation for the pile while the second uses a finite difference formulation. It is shown that, although both methods give similar results for uniform section piles, the finite difference formulation becomes inaccurate when abrupt step changes in pile section are considered. Some parametric solutions are presented for a uniformly tapered pile, and these are presented as correction factors to the solutions for uniform section piles. Finally, two practical examples are given to illustrate the application of the analysis. /Author/

Lateral Response of Piles

Response of a single pile to moment or lateral thrust is analyzed considering the surrounding soil to be an elastic-plastic continuum. The soil mass is considered to be elastic with progressive zones of yielding developing, depending on an arbitrary yield criterion. Curves for a typical example are presented showing pile loading and deflection versus depth, as well as load versus lateral deflection at the ground surface. A nonlinear load-deflection response is predicted that is similar in nature to observed field behavior.
