Practical Methods For The Analysis Of Piled Raft Foundations

The use of piled raft foundations has significantly increased over the last few decades since taking into account the contribution of the raft to the overall bearing capacity enabled the engineers to design much more efficient piled foundations which perform as well as the conventionally designed ones with significantly lower number of piles. However, although many researchers have been studying on this subject, a user-friendly design procedure is still not available in the literature. This book, therefore, offers two different simple methods to estimate the settlements of the piled raft foundations. Utilizing the charts provided in this book, the settlement of a piled raft foundation can be obtained by simple hand calculations in the first method while it can be calculated by computerized analysis in the second one. This book should be especially useful for the geotechnical experts and/or engineers looking for a simplified method for the analysis of piled rafts and academicians who are interested in the subject.

Available Textbooks, Handbooks, Various Publications And Papers Give Widely Different Approaches For Design Of Raft Foundations. These Approaches Make Their Own Assumptions And Deal With Ideal Raft, Symmetrical In Shape And Loading. In Actual Practice Rafts Are Rarely So. A Structural Designer Engaged In The Design Of Raft Foundations Finds It Hard To Select The Method That Can Be Carried Out Within The Time And Cost Available For Design And Give Adequate Safety And Economy.This Book Covers Complete Design Of Raft Foundations Including Piled Rafts, Starting From Their Need, Type, All The Approaches Suggested So Far In Published Literature, Effect Of Assumptions Made And Values Of Variables Selected, On The Design Values Of Stresses, And Brings Out The Limitations Of These Approaches Using Actually Constructed Rafts.Results Of Studies Carried Out By The Author Are Summarised And Final Recommendations Given. Solved Examples Are Included For Each Of The Methods Recommended. Comprehensive Treatment Of The Subject Makes The Book Helpful To The Design Engineers, Engineering Teachers, Students And Even Those Who Are Engaged In Further Research.

This book examines alternative design procedures for plain and piled raft foundations. It explores the assumptions that are made in the analysis of soil - structure interaction, together with the associated calculation methods. The book gives many examples of project applications covering a wide range of structural forms and ground conditions.

Piled foundations are generally designed using empirical methods, in particular the traditional capacity based approach on which the majority of codes of practice are based. However in recent years the analysis of pile groups and piled rafts has undergone substantial development in the light of new research and the mechanisms for the interactions b
