Download or read book Earth Pressure written by Achim Hettler and published by John Wiley & Sons. This book was released on 2020-01-13 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of earth pressure is one of the oldest and most extensive chapters in soil mechanics and foundation engineering and is one of the pillars of structural engineering. First the development of earth pressure theory is comprehensively described. The descriptions range from the first approaches to the determination of earth pressure through continuum mechanical earth pressure models to the integration of earth pressure research into the disciplinary structure of geotechnics. The main part of the book comprises a selection of current calculation basics. The aim is to provide a collection of working instructions for foundation and structural engineers in construction companies, consultants and in building supervision as well as students. In order to further theoretical understanding, the essential basics of the determination of earth pressure are first presented. Then the most important processes for active and passive earth pressure and at-rest earth pressure for practical application are dealt with, with spatial effects also being taken into account. The book sets out to provide brief information about rarely encountered questions with references to further literature. In recent years, the dependency of earth pressure on displacement has been paid ever more attention. This applies not just to the passive but also to the active case. Questions are repeatedly passed to the DIN committee "calculation processes". A selection of these is dealt with in the commentary to DIN 4085, which came out in September 2018. The history of earth pressure theory is supplemented by 40 selected short biographies of scientists and practical engineers, who have taken up the subject and further developed it over the years. The book also has two appendices with terms, formula symbols and indices as well as earth pressure tables.
Download or read book Holistic Simulation of Geotechnical Installation Processes written by Theodoros Triantafyllidis and published by Springer. This book was released on 2015-10-30 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines in detail the entire process involved in implementing geotechnical projects, from a well-defined initial stress and deformation state, to the completion of the installation process. The individual chapters provide the fundamental knowledge needed to effectively improve soil-structure interaction models. Further, they present the results of theoretical fundamental research on suitable constitutive models, contact formulations, and efficient numerical implementations and algorithms. Applications of fundamental research on boundary value problems are also considered in order to improve the implementation of the theoretical models developed. Subsequent chapters highlight parametric studies of the respective geotechnical installation process, as well as elementary and large-scale model tests under well-defined conditions, in order to identify the most essential parameters for optimizing the process. The book provides suitable methods for simulating boundary value problems in connection with geotechnical installation processes, offering reliable predictions for the deformation behavior of structures in static contexts or dynamic interaction with the soil.

Download or read book Recommendations on Excavations written by Deutsche Gesellschaft für Geotechnik and published by John Wiley & Sons. This book was released on 2009-02-05 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of these recommendations is to harmonize and further develop the methods, according to which excavations are prepared, calculated and carried out. Since 1980, these have been drawn up by the working group "Excavations" at the German Geotechnical Society (Deutsche Gesellschaft fur Geotechnik DGGT) and are similar to a set of standards. They help to simplify analysis of excavation enclosures, to unify load approaches and analysis procedures, to guarantee the stability and serviceability of the excavation structure and its individual components, and to find out an economic design of the excavation structure. For this new edition, all recommendations have been reworked in accordance with EN 1997-1 (Eurocode 7) and DIN 1054-1. In addition, new recommendations on the use of the modulus of subgrade reaction method and the finite element method (FEM), as well as a new chapter on excavations in soft soils, have been added.
Download or read book Pile groups under cyclic lateral loading written by Christoph Niemann and published by BoD – Books on Demand. This book was released on 2020-01-01 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is the aim of this research work is to investigate and to assess quatitatively as well as quantitatively the bearing behaviour of pile groups subjected to cyclic lateral loading. In this context, the influences of different boundary conditions, in particular the soil properties and the pile group geometry are to be analysed experimentally and numerically. Based on a brief literature review in chapter 2, model tests (centrifuge and small-scale at 1g) and numerical investigations have been carried out to contribute to a better understanding of the cyclic behaviour of pile groups. Chapter 3 describes the test procedure and summarises the results of centrifuge tests, which have been carried out at the Centre for Offshore Foundation Systems (COFS) in Perth, Australia. Further investigations have been carried out by means of smallscale model tests at 1g in the testing facilities at the University of Kassel, Germany, with the results as summarised in chapter 4. A comparison of individual results of both test series is provided in chapter 5. The numerical studies in chapter 6 have been carried out in order to analyse the general ability of numerical simulations to calculate the response of pile groups to cyclic lateral loading. Based on the previously derived results, chapter 7 provides equations that can be applied to estimate the cyclic accumulation of lateral displacements of pile groups as well as the cyclic changes of the load distribution within pile groups.
Download or read book Combined Pile Raft Foundations written by Oliver Reul and published by CRC Press. This book was released on 2024-12-16 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the fundamental features of the design and performance of combined pile-raft foundations (CPRFs). Whereas in a traditional foundation the loads are carried either by the raft or by the piles, the capacity of CPRFs is assessed for the foundation as a whole, reducing total and differential settlements economically. The five chapters provide an overview of the historical development of piled rafts in practice and research, and of the design concepts developed for piled rafts over the last decades. Fundamental aspects of their bearing behaviour are presented, as well as an overview of the framework of the design process for CPRFs, including the safety concept, the design approach summarised in the ISSMGE Combined Pile-Raft Foundation Guideline (ISSMGE TC 212 2013) and the interaction between structural and geotechnical engineering. For numerical analysis based on the finite element method, guidance is given on creating the model and performing the calculations before providing basic information on the requirements for the site investigation, supervision of the construction process and monitoring of the foundation performance. Detailed case studies illustrate the design and performance of CPRFs, and a design example for the foundation of a multi-storey office building founded in non-cohesive soil is investigated, carrying out 3D finite element analysis to estimate deformations and design parameters for structural engineering. Based on the combined experience of the authors obtained in the last decades working in the industry and research, the book particularly suits consulting engineers engaged in foundation engineering, as well as graduate students and researchers interested in the bearing behaviour of piled rafts and pile groups.

Download or read book On the Face Stability of Shallow Tunnels in Sand written by Ansgar Kirsch and published by Logos Verlag Berlin GmbH. This book was released on 2009 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various models have been proposed for the prediction of the necessary support pressure at the face of a shallow tunnel. To assess their quality, the collapse of a tunnel face was modelled with small scale model tests at single gravity. The evolution of the failure mechanism and the development of the support force at the face in dry sand were investigated. The observed displacement patterns show a negligible influence of overburden on the extent and evolution of the failure zone. The latter is significantly influenced, though, by the initial density of the sand: in dense sand a chimney-wedge-type collapse mechanism developed, which propagated towards the soil surface. Initially loose sand did not show any development of a discrete collapse mechanism. The necessary support force was neither influenced by the overburden nor the initial density. A comparison with quantitative predictions by several theoretical models showed that the measured necessary support pressure is overestimated by most of the models. Only those by Vermeer/Ruse and Leca/Dormieux were able to predict the necessary support pressure on a 95 % confidence level. A three-dimensional finite element investigation of face stability served to assess the ability of two constitutive models, an elastoplastic Mohr-Coulomb and a hypoplastic model, to predict the necessary support pressure and the displacements at the tunnel face. The simulation of the small scale experiments revealed that the observed necessary support pressure and incremental displacements were predicted sufficiently well with both constitutive models.
Download or read book The History of the Theory of Structures written by Karl-Eugen Kurrer and published by John Wiley & Sons. This book was released on 2012-01-09 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book traces the evolution of theory of structures and strength of materials - the development of the geometrical thinking of the Renaissance to become the fundamental engineering science discipline rooted in classical mechanics. Starting with the strength experiments of Leonardo da Vinci and Galileo, the author examines the emergence of individual structural analysis methods and their formation into theory of structures in the 19th century. For the first time, a book of this kind outlines the development from classical theory of structures to the structural mechanics and computational mechanics of the 20th century. In doing so, the author has managed to bring alive the differences between the players with respect to their engineering and scientific profiles and personalities, and to create an understanding for the social context. Brief insights into common methods of analysis, backed up by historical details, help the reader gain an understanding of the history of structural mechanics from the standpoint of modern engineering practice. A total of 175 brief biographies of important personalities in civil and structural engineering as well as structural mechanics plus an extensive bibliography round off this work.
Download or read book Geotechnik written by Dimitrios Kolymbas and published by Springer-Verlag. This book was released on 2017-04-10 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dieses Buch behandelt die Bodenmechanik und ihre Anwendungen in der Baupraxis (Geotechnik, Grundbau, Spezialtiefbau, Tunnelbau). Boden nimmt als granularer Stoff eine Zwischenstellung zwischen Feststoffen und Fluiden ein. Daher ist die Bodenmechanik nicht nur praxisrelevant, sondern auch eines der interessantesten Gebiete für die Forschung. Die Wechselwirkungen des Bodens mit dem Wasser machen die Bodenmechanik theoretisch noch anspruchsvoller und für die Praxis noch wichtiger. Zu einer Zeit, wo Regelwerke und Normen unüberschaubar werden, kommt es mehr denn je auf das Verständnis der zugrunde liegenden Konzepte an. Der Autor legt größten Wert auf ihre übersichtliche Darstellung, sowohl in der Theorie als auch in der Praxis, die sich in der Geotechnik rasant verändert. Veraltete Theorien und Bauverfahren wurden ausgelassen, und dafür wurde ein Einblick in die vielfältigen Randgebiete der Geotechnik gewährt.
