Download or read book Uplift Capacity and Displacement of Helical Anchors in Cohesive Soil written by Jessica Marie Young and published by . This book was released on 2012 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Helical anchors are a type of deep foundation element that can be installed quickly in almost any location and can accept the immediate application of operational loads. The use of helical anchors has expanded in recent decades from its established application in the power transmission industry to more traditional civil engineering applications such as residential construction, communication tower installations, and static and seismic structural retrofitting and reconstruction. Despite the wide range of helical anchor applications, few advances have been made in improving the understanding of their behavior. For example, existing helical anchor design methods, for cases where the anchors are loaded in uplift in cohesive soils, are based on the assumption that the soil above the helical plate is mobilized in a manner analogous to that beneath a deep foundation in bearing. An appropriate design method would acknowledge the effect of load directionality on the assumed failure mechanism. This thesis evaluates the existing cylindrical shear and individual plate bearing design methods for helical anchor capacity in uplift. Additionally, new capacity models are proposed to improve prediction accuracy and reduce prediction variability. A load test database of helical anchors loaded in tension is established from tests reported in the literature. The existing and proposed capacity models are compared to the capacities observed during loading tests using the statistical bias and its distribution. Load and Resistance Factor Design (LRFD) resistance factors are derived from closed-form solutions using First Order Second Moment (FOSM) reliability procedures. Finally, load-displacement models are developed through the evaluation of observed individual anchor plate breakout behavior and back-calculation of side shear capacity from load tests on multi-plate anchors. The new displacement models are compared to the load-displacement tests in the database. In general the comparisons indicate that the displacement-based models developed in this thesis provide a reasonable estimate of load-displacement behavior of helical anchors for service-level displacements. These findings provide engineers with new tools for design of helical anchor foundations.

Download or read book Soil Reinforcement for Anchor Plates and Uplift Response written by Hamed Niroumand and published by Butterworth-Heinemann. This book was released on 2017-03-18 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil Reinforcement for Anchor Plates and Uplift Response presents a comprehensive and rigorous review of the current knowledge in soil improvement for anchor plates, and is based on original research that includes experimental data on how to enhance uplift response of soil anchor plates by using several soil reinforcement methods. Divided into 6 chapters, the author makes an introduction to both Ancho Plates and Soil Reinforcement in chapter one, then providing a comprehensive literature review on the topic in chapter 2. Chapter 3 presents how the experiment was set up, the different types of geotextiles used, and the types of soil tested. Chapter 4 presents experimental data, along with data provided by simulation softwares, including Plaxis. Chapter 5 compares the experimental results to the numerical simulation data, providing researchers and geotechnical engineers with tools they can apply to their own projects. In chapter 6, the author presents his conclusions and recommendations on the usage of soil reinforcement to maximize uplift response to anchor plates. Researchers in geotechnical engineering can use the methods and experimental data presented in the book on their own projects, and practicing engineers will benefit from the comparisons between experimental and simulation data provided to make appropriate selection of soil reinforcement techniques that can be applied to their projects. - Presents techniques for improving uplift response by 40% or more - Discusses the uplift capacity of symmetrical anchor plates in several scenarios - Provides a complete review of soil reinforcement for anchor plates - Includes numerical analyses methods for validating experimental test results

Available in PDF, EPUB and Kindle. Book excerpt: Model Uncertainties in Foundation Design is unique in the compilation of the largest and the most diverse load test databases to date, covering many foundation types (shallow foundations, spudcans, driven piles, drilled shafts, rock sockets and helical piles) and a wide range of ground conditions (soil to soft rock). All databases with names prefixed by NUS are available upon request. This book presents a comprehensive evaluation of the model factor mean (bias) and coefficient of variation (COV) for ultimate and serviceability limit state based on these databases. These statistics can be used directly for AASHTO LRFD calibration. Besides load test databases, performance databases for other geo-structures and their model factor statistics are provided. Based on this extensive literature survey, a practical three-tier scheme for classifying the model uncertainty of geo-structures according to the model factor mean and COV is proposed. This empirically grounded scheme can underpin the calibration of resistance factors as a function of the degree of understanding – a concept already adopted in the Canadian Highway Bridge Design Code and being considered for the new draft for Eurocode 7 Part 1 (EN 1997-1:202x). The helical pile research in Chapter 7 was recognised by the 2020 ASCE Norman Medal.

Download or read book Earth Anchors written by B.M. Das and published by Elsevier. This book was released on 2012-12-02 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anchors are primarily used in the construction of foundations of earth-supported and earth-retaining structures. The anchors are used in construction to transmit the outwardly-directed load to soil at a greater depth and/or farther from the structure. Although earth anchors have been used in practice for several hundred years, proper theoretical developments for purposes of modern engineering design have taken place only during the past twenty years or so. This book summarizes most of the theoretical and experimental works directed toward the ultimate and allowable holding capacity of earth anchors. The book contains six chapters with detailed discussions on horizontal, vertical and inclined anchor plates, helical anchors, and anchor piles. Discussions on the failure mechanism in soil located around the anchor, as well as various theories to calculate the ultimate and allowable loads, are presented. Laboratory and field test results which are required to supplement and verify the theories have also been included. This book is of interest to consulting engineers in geotechnical engineering, as well as geotechnical engineering researchers and engineering libraries.

Book excerpt: Anchors are primarily used in the construction of foundations of earth-supported and earth-retaining structures. The fundamental reason for using earth anchors in construction is to transmit the outwardly directed load to the soil at a greater depth and/or farther away from the structure. Although earth anchors have been used in practice for several hundred years, proper theoretical developments for purposes of modern engineering designs have taken place only during the past 40 to 45 years. This book summarizes most theoretical and experimental works directed toward the development of proper relationships for ultimate and allowable holding capacity of earth anchors. J. Ross Publishing offers a supplemental download — A customizable PowerPoint instructional slide presentation prepared by the authors that complements the material covered in the book, chapter-by-chapter.

Available in PDF, EPUB and Kindle. Book excerpt: Theoretical Foundation Engineering provides up-to-date, state-of-the-art reviews of the existing literature on lateral earth pressure, sheet pile walls, ultimate bearing capacity of shallow foundations, holding capacity of plate and helical anchors in sand and clay, and slope stability analysis. The discussion of the ultimate bearing capacity of shallow foundations is the most comprehensive presentation on the subject to be found anywhere, and the review of earth anchors is unique to this book. In addition, each chapter includes several topics which have never appeared in any other book. The treatment is primarily theoretical and does not in any way compete with existing foundation design books. This is the only textbook of its kind. Not only will it be welcomed by teachers and first-year graduate students of geotechnical engineering, but it will be a useful reference for graduate students and consultants in the the field, as well as being a valuable addition to any civil engineering library.
