Available in PDF, EPUB and Kindle. Book excerpt: In order to analyze foundations supported by groups of vertical, pin-headed, laterally loaded piles, it is necessary to include in some rational way the effect of pile-soil-pile interaction, or the increase in pile-head flexibility that occurs in each pile in a group in comparison with an isolated pile. A study was undertaken to measure experimentally pile-head flexibility reduction (interaction) factors in a full-scale pile group in sand. The measurements were accomplished by testing individual piles within a pile group of nine piles cyclically at varying magnitudes of applied ground line shear, two-pile subgroups and three-pile subgroups. The response of certain unloaded piles was also monitored during these individual-pile and small-group tests. Analysis of the results indicated a significant effect of position on flexibility reduction in a two-pile group (leading or trailing) for piles spaced 3 diameters on center and loaded in line and a lesser effect for piles loaded side-by-side. A consistent set of interaction factors was developed from the experiments and applied to the analysis of deflection and shear load distribution in the full nine-pile group, which had been tested earlier on the same test site, through the use of simple matrix techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Energy geostructures are a tremendous innovation in the field of foundation engineering and are spreading rapidly throughout the world. They allow the procurement of a renewable and clean source of energy which can be used for heating and cooling buildings. This technology couples the structural role of geostructures with the energy supply, using the principle of shallow geothermal energy. This book provides a sound basis in the challenging area of energy geostructures. The objective of this book is to supply the reader with an exhaustive overview on the most up-to-date and available knowledge of these structures. It details the procedures that are currently being applied in the regions where geostructures are being implemented. The book is divided into three parts, each of which is divided into chapters, and is written by the brightest engineers and researchers in the field. After an introduction to the technology as well as to the main effects induced by temperature variation on the geostructures, Part 1 is devoted to the physical modeling of energy geostructures, including in situ investigations, centrifuge testing and small-scale experiments. The second part includes numerical simulation results of energy piles, tunnels and bridge foundations, while also considering the implementation of such structures in different climatic areas. The final part concerns practical engineering aspects, from the delivery of energy geostructures through the development of design tools for their geotechnical dimensioning. The book concludes with a real case study. Contents Part 1. Physical Modeling of Energy Piles at Different Scales 1.

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

Download or read book Elastic Analysis of Soil Foundation Interaction written by A.P.S. Selvadurai and published by Elsevier. This book was released on 2013-10-22 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geotechnical Engineering, Vol. 17: Elastic Analysis of Soil-Foundation Interaction focuses on the analysis of the interaction between structural foundations and supporting soil media. The publication first elaborates on soil-foundation interaction problems; idealized soil response models for the analysis of soil-foundation interaction; and plane-strain analysis of an infinite plate and an infinitely long beam. Discussions focus on three-dimensional effects in the infinite beam problem, elastic models of soil behavior, foundation and interface behavior, and elastic-plastic and time-dependent behavior of soil masses. The manuscript then ponders on the analysis of beams of finite length, axisymmetric three-dimensional problem of an infinite plate, and analysis of finite plates. Concerns cover axisymmetric loading of a circular plate, analysis of rectangular plates, axisymmetric three-dimensional problem of the infinite plate, modifications of the thin plate theory, finite beams on a two-parameter elastic medium, and finite beams on an elastic solid medium. The book tackles the determination of soil parameters, experimental investigations and field studies, as well as experimental investigations and field studies and measurement and interpretation of parameters encountered in the idealized soil models in relation to soil-foundation behavior. The publication is a valuable reference for researchers interested in the elastic analysis of soil-foundation interaction.

This book was released on 1988 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: A research program to study the behavior of piles and pile groups subjected to cyclic lateral loading was conducted at a Houston, Texas site. A single pile and a nine-pile group situated in the natural clay were tested and then the upper several feet of clay were removed and replaced with sand and the tests were repeated. Following these tests, another study was undertaken to measure experimentally pile-head flexibility reduction (interaction) factors for the pile group in sand. Tests were made cyclically at varying magnitudes of applied groundline shear on single piles and two-pile and three-pile subgroups, and the response of unloaded piles in the group was measured. Concurrent with these studies, pressuremeter (PMT) and cone penetrometer (CPT) tests were performed in both the clay and the sand from which capacity predictions were made. Each of these studies generated a report with voluminous data. This report summarizes the major findings into one volume. Keywords: Cyclic lateral loading, Interaction factors, Piles, Pile groups, Scour, Pile structures. (SDW).

This book was released on 2007-10-01 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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