Chapter 2: Analysis of laterally loaded pile foundations using subgrade reaction method. Christos Vrettos (Technical University Kaiserslautern, Germany). Chapter 1: Design of piles for static loads. The book is considered a valuable tool for practicing engineers, graduate students and researchers. The book is unique in its unified treatment of the solutions used for static and dynamic analysis of piles with practical examples of application. Both linear and nonlinear soil behaviours are considered along with response due to dynamic loads and earthquake shaking including possible liquefaction. These chapters cover a range of solutions from dynamic pile-soil springs to elasto-dynamic solutions of large pile groups. The applications range from conventional piles to large circular steel piles used as anchors or monopiles in offshore applications.Ĭhapters 5 to 10 are devoted to dynamic and earthquake analyses and design. The analysis techniques cover conventional code-based methods, solutions based on pile-soil interaction springs, and advanced 3D finite element 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 materials are presented in a unified manner based on both simplified and rigorous numerical methods.

The chapters are written by world-renowned experts in the field. The chapters provide a mixture of basic engineering solutions and latest research findings in a balanced manner. Empirical relations for the available experimental findings were established to confirm the source of disagreement as well as to afford a unified relation which might represent data of different materials, and finally to offer an alternative prediction of experimental peak load.This book presents computational tools and design principles for piles used in a wide range of applications and for different loading conditions. This partial disagreement was proved to be attributed to the questionable data extracted from one of the cited work. It was also found that all numerical results agree favorably with the theoretical predictions, but not with all of the experimental findings.

Moreover, the upper bound stress requires both D/t and L/D ratios. It is found that the peak load is unique for a particular specimen, while the lower bound stress can be equal for different values of D, t and L, as long as the D/t ratio is the same. Previous findings were compared with both the theoretical and numerical results of the present work. Numerical simulations were also made to validate these estimates using ABAQUS 14-2 finite element software. Theoretical estimates of the peak load were formulated for lower and upper bounds based on Rankine-Gordon principle and the elastic-plastic criterion of buckling, respectively. The axial crushing of thin-walled metal circular tubes was addressed in this work for its importance in many engineering applications especially when failed in concertina mode.
