The complexities of designing piles for lateral loads are manifold as there are many forces that are critical to the design of big structures such as bridges, offshore and waterfront structures and retaining walls. The loads on structures should be supported either horizontally or laterally or in both directions and most structures have in common t
Guiding the professional through the complexities of lateral-load design, this book and CD-ROM combination introduces the procedures involved in piles and pile group design. This is a problem that can only be solved by accounting for the soil resistance as related to the lateral deflection of the pile. Intricate equations are derived and fully explained, enabling the designer to find the critical loads, either causing a pile to be overloaded or causing too much lateral deflection. The CD-ROM contains simplified versions of two required programs that allow the reader to check the solutions of some of the examples given in the book and to find answers to related problems.

The field of lateral-load design is a very complex one. This book and CD-ROM not only provides the reader with an overview of procedures involved in the designing of piles and pile groups, but with a way of finding answers to related problems.
This Handbook is specifically designed as a guide to highway engineers. It was used as a textbook for the FHWA training courses on the above title. Several methods of analysis and design of piles under lateral loading are in use. Two methods are presented: the method of Broms, and the method where nonlinear soil-response curves, p-y curves, are employed. The latter method is given prominence because of its versatility. A computer program is presented for solving the equations giving pile deflection, rotation, bending moment, and shear. An iterative procedure is employed internally in the computer program because of the nonlinear response of the soil. Nondimensional curves are presented that can be used for "hand" solution of the differential equation.
This report focuses on the development of a new method of analysis of laterally loaded piles embedded in a multi-layered soil deposit treated as a three-dimensional continuum. Assuming that soil behaves as a linear elastic material, the governing differential equations for the deflection of laterally loaded piles were obtained using energy principles and calculus of variations. The differential equations were solved using both the method of initial parameters and numerical techniques. Soil resistance, pile deflection, slope of the deflected pile, bending moment and shear force can be easily obtained at any depth along the entire pile length. The results of the analysis were in very good agreement with three-dimensional finite element analysis results. The analysis was further extended to account for soil nonlinearity. A few simple constitutive relationships that allow for modulus degradation with increasing strain were incorporated into the analysis. The interaction of piles in groups was also studied.
Pile Foundations are an essential basis for many structures. It is vital that they be designed with the utmost reliability, because the cost of failure is potentially huge. Covering a whole range of design issues relating to pile design, this book presents economical and efficient design solutions and demonstrates them using real world examples. Coverage includes nonlinear response of single piles to vertical or torsional loading and to cyclic lateral loading, as well as prediction of nonlinear response of lateral pile groups, vertically loaded pile groups and the design of slope stabilising piles. Most solutions are provided as closed-form expressions. Theory and Practice of Pile Foundations is: illustrated with case studies accompanied by practical applications in Excel and MathCad the first book to incorporate nonlinear interaction into pile design. A valuable resource for students of geotechnical engineering taking courses in foundations and a vital tool for engineers designing pile foundations.
This book presents computational tools and design principles for piles used in a wide range of applications and for different loading conditions. The chapters provide a mixture of basic engineering solutions and latest research findings in a balanced manner. The chapters are written by world-renowned experts in the field. The materials are presented in a unified manner based on both simplified and rigorous numerical methods. The first four chapters present the basic elements and steps in analysis of piles under static and cyclic loading together with clear references to the appropriate design regulations in Eurocode 7 when relevant. The analysis techniques cover conventional code-based methods, solutions based on pile-soil interaction springs, and advanced 3D finite element methods. The applications range from conventional piles to large circular steel piles used as anchors or monopiles in offshore applications. Chapters 5 to 10 are devoted to dynamic and earthquake analyses and design. These chapters cover a range of solutions from dynamic pile-soil springs to elasto-dynamic solutions of large pile groups. Both linear and nonlinear soil behaviours are considered along with response due to dynamic loads and earthquake shaking including possible liquefaction. The book is unique in its unified treatment of the solutions used for static and dynamic analysis of piles with practical examples of application. The book is considered a valuable tool for practicing engineers, graduate students and researchers.
