LOAD ON PILES

2.2 Introduction

This section of the guide is divided into two parts. The first part gives brief
summary on basic pile arrangements while part two deals with load distribution
on individual piles.

Piles can be arranged in a number of ways so that they can support load imposed
on them. Vertical piles can be designed to carry vertical loads as well as lateral
loads. If required, vertical piles can be combined with raking piles to support
horizontal and vertical forces.

often, if a pile group is subjected to vertical force, then the calculation of load
distribution on single pile that is member of the group is assumed to be the total
load divided by the number of piles in the group. However if a group of piles is
subjected to lateral load or eccentric vertical load or combination of vertical and
lateral load which can cause moment force on the group which should be taken
into account during calculation of load distribution.

In the second part of this section, piles are considered to be part of the structure
and force distribution on individual piles is calculated accordingly.



Objective: In the first part of this section, considering group of piles with

limited number of piles subjected to vertical and lateral forces, forces acting
centrally or eccentrically, we learn how these forces are distributed on
individual piles.

The worked examples are intended to give easy follow through exercise that can
