Book Description
The dynamic response of pile foundations in soft clay and liquefiable sand during strong earthquake shaking was evaluated. The research consisted of two major components: (1) a series of dynamic centrifuge tests of pile-supported structures in soft clay and liquefiable sand; and (2) an evaluation of dynamic "beam on a nonlinear Winkler foundation" (BNWF) analysis methods against the centrifuge model results.

Single Piles in Liquefiable Ground
Author: Rui Wang
Publisher: Springer
ISBN: 3662496631
Category : Science
Languages : en
Pages : 131
Book Description
This thesis focuses on the seismic response of piles in liquefiable ground. It describes the design of a three-dimensional, unified plasticity model for large post-liquefaction shear deformation of sand, formulated and implemented for parallel computing. It also presents a three-dimensional, dynamic finite element analysis method for piles in liquefiable ground, developed on the basis of this model,. Employing a combination of case analysis, centrifuge shaking table experiments and numerical simulations using the proposed methods, it demonstrates the seismic response patterns of single piles in liquefiable ground. These include basic force-resistance mode, kinematic and inertial interaction coupling mechanism and major influence factors. It also discusses a beam on the nonlinear Winkler foundation (BNWF) solution and a modified neutral plane solution developed and validated using centrifuge experiments for piles in consolidating and reconsolidating ground. Lastly, it studies axial pile force and settlement during post-earthquake reconsolidation, showing pile axial force to be irrelevant in the reconsolidation process, while settlement is process dependent.

Design of Pile Foundations in Liquefiable Soils
Author: Gopal Madabhushi
Publisher: Imperial College Press
ISBN: 1848163630
Category : Science
Languages : en
Pages : 232
Book Description
Pile foundations are the most common form of deep foundations that are used both onshore and offshore to transfer large superstructural loads into competent soil strata. This book provides many case histories of failure of pile foundations due to earthquake loading and soil liquefaction. Based on the observed case histories, the possible mechanisms of failure of the pile foundations are postulated. The book also deals with the additional loading attracted by piles in liquefiable soils due to lateral spreading of sloping ground. Recent research at Cambridge forms the backbone of this book with the design methodologies being developed directly based on quantified centrifuge test results and numerical analysis. The book provides designers and practicing civil engineers with a sound knowledge of pile behaviour in liquefiable soils and easy-to-use methods to design pile foundations in seismic regions. For graduate students and researchers, it brings together the latest research findings on pile foundations in a way that is relevant to geotechnical practice. Sample Chapter(s). Foreword (85 KB). Chapter 1: Performance of Pile Foundations (4,832 KB). Contents: Performance of Pile Foundations; Inertial and Kinematic Loading; Accounting for Axial Loading in Level Ground; Lateral Spreading of Sloping Ground; Axial Loading on Piles in Laterally Spreading Ground; Design Examples. Readership: Researchers, academics, designers and graduate students in earthquake engineering, civil engineering and ocean/coastal engineering.

Analysis of Pile Foundations Subject to Static and Dynamic Loading
Author: Amir M. Kaynia
Publisher: CRC Press
ISBN: 1000398587
Category : Technology & Engineering
Languages : en
Pages : 401
Book Description
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.

Seismic Response of Pile Foundations

Book Description
"A boundary element formulation is presented to analyze the seismic response of a single pile. The piles are modeled by compressible beam-column elements and the soil as a hysteretic elastic half-space. A new Green's function corresponding to dynamic loads in the interior of a semi-infinite solid is developed for this study. The governing differential equations of motion for the pile domain have been solved exactly for distributed periodic loading intensities. These solutions were then coupled with a numerical solution for the motion of the soil domain by satisfying equilibrium and compatibility at the pile-soil interface. The responses were evaluated over wide ranges of the parameters involved to vertically and obliquely incident P, SV and SH-waves. Results are presented as dimensionless graphs and the pile-soil interaction is studied. It is observed that the existence of the pile produces a filtering of the waves, reducing the amplitude of motion as a function of frequency. Also, the filtering effects, pile motions and amplitudes are found to be dependent on the slenderness ratio, stiffness ratio and angle of incidence. Finally, an actual transient analysis is performed to study the response of piles to seismic waves in the time domain."--Abstract
