A simple, efficient method is presented for the analysis of large pile groups subjected to vertical loads, horizontal loads, and moments acting either statically or dynamically with low frequencies. The soil profile and the arrangement of the piles may be arbitrary but the solution is particularly efficient for groups with double symmetry or axisymmetry. The group is analyzed directly, avoiding the use of interaction factors, but the interaction factors are also presented. The piles can be of any type, i.e., floating, end-bearing, socketed, or with a pedestal.read more

Analysis of capped pile groups subjected to horizontal and vertical loads
H.H Zhang,John C. Small +1 more
TL;DR: In this paper, a method of analysis for an off-ground cap supported by piles embedded in a layered soil and subjected to horizontal and vertical loads is presented, where the cap is modelled as a thin plate and the piles as elastic beams and the soil is treated as consisting of horizontal layers of different materials.

Pile Foundation Analysis and Design
Harry G. Poulos,E.H. Davis +1 more
TL;DR: In this paper, the authors present a consistent theoretical approach to the prediction of pile deformation and load capacity, and present parametric solutions for a wide range of cases, demonstrating how such solutions can be used for design purposes, and review the applicability of these approaches to practical problems.

The response of flexible piles to lateral loading
TL;DR: In this article, a parametric study was conducted using the finite element method and treating the soil as an elastic continuum with a linearly varying soil modulus, and the results of a simple algebraic expression for the active length of the pile; the ground level deformations; and the maximum bending moment down the pile were presented.

Analysis of the Settlement of Pile Groups
TL;DR: In this paper, an analysis of the settlement interaction between two identical piles in an elastic mass and the increase in settlement of each pile due to interaction is expressed in terms of an interaction factor α.
