Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This chapter presents a concise overview of the mechanics of failure, analysis and requalification procedures of pile foundations in liquefiable soils during earthquakes. The aim is to build a strong conceptual and technical interpretation in order to gain insight into the mechanisms governing the failure of structures in liquefaction and specify effective requalification techniques. In this regard, several most common failure mechanisms of piles during seismic liquefaction such as bending (flexural), buckling instability and dynamic failure of the pile are introduced. Furthermore, the dynamic response commentary is provided by critically reviewing experimental investigations carried out using a shaking table and centrifuge modelling procedures. The emphasis is placed on delineating the concept of seismic design loads and important aspects of the dynamic behaviour of piles in liquefiable soils. In this context, using Winkler foundation approach with the proposed p,Äìy curves and finite-element analyses in conjunction with numerical analysis methods, are outlined. Moreover, the feasibility of successful remediation techniques for earthquake resistance is briefly reviewed in light of the pile behaviour and failure. Finally, practical recommendations for achieving enhanced resistance of the seismic response of pile foundation in liquefiable soil are provided.

Download or read book Analysis of Pile Foundations Subject to Static and Dynamic Loading written by Amir M. Kaynia and published by CRC Press. This book was released on 2021-08-30 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Nonlinear Behavior and Modeling of Piles in Partially Liquefied and Layered Soil Conditions written by Barbara Jean Chang and published by . This book was released on 2011 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Saturated soils, particularly cohesionless soils, may liquefy when subjected to earthquake excitation, resulting in reductions in strength and stiffness of the soil. The consequences have shown to be devastating to foundations in past earthquakes. For pile foundations, a reduction of vertical or lateral soil resistance may cause failure of the super structure. To study this issue, two unique 1-g soil-pile tests were conducted. The models were constructed in a laminar soil box which was subsequently placed on a uniaxial shake table. One experiment focused on characterizing the soil resistance of partially liquefied soil, while the other on multi-layered soil and the effect of its movement and load demands on the nonlinear behavior of piles. These two different experimental configurations illustrate scenarios commonly observed in the field, where the behavior of the soil and the pile merit further investigation. While evidence in the literature indicates that the lateral soil ("p-y") resistance of piles in liquefiable soils is significantly reduced, the shape and amplitude of the reduced p-y curve during pore pressure build-up is not well understood. To investigate this, a single steel pile embedded in homogeneous saturated Nevada sand was subjected to sequential dynamic shaking and lateral inertial equivalent loading. A key goal in the test program was to develop a data set capable of rendering insight into the characteristics of p-y resistance under developing and partial liquefied soil conditions. Test data were used to back-calculate p-y resistance curves for partially liquefied soils. These curves are subsequently adopted in a numerical study of the behavior of piles in partially liquefied soils considering different layering conditions. In contrast, in a multi-layered soil profile, if a loose layer liquefies, large localized plastic demands may be generated in the piles. In the case of concrete piles, these demands manifest flexural cracks in the concrete, which weakens the pile and exposes it to subsequent environmental degradation. During the experiments conducted herein to study this issue, plastic demands in the pile were characterized using curvature profiles coupled with back-calculation of the plastic hinge length and post-test physical observations. Numerical modeling studies demonstrate the applicability of current design-oriented tools to capture these key response parameters needed for design.
