Book Pile groups under cyclic lateral loading

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.

Book On the Face Stability of Shallow Tunnels in Sand

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.

Book Seismic Design and Retrofit of Bridges

Download or read book Seismic Design and Retrofit of Bridges written by M. J. N. Priestley and published by John Wiley & Sons. This book was released on 1996-04-12 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of their structural simplicity, bridges tend to beparticularly vulnerable to damage and even collapse when subjectedto earthquakes or other forms of seismic activity. Recentearthquakes, such as the ones in Kobe, Japan, and Oakland,California, have led to a heightened awareness of seismic risk andhave revolutionized bridge design and retrofit philosophies. In Seismic Design and Retrofit of Bridges, three of the world's topauthorities on the subject have collaborated to produce the mostexhaustive reference on seismic bridge design currently available.Following a detailed examination of the seismic effects of actualearthquakes on local area bridges, the authors demonstrate designstrategies that will make these and similar structures optimallyresistant to the damaging effects of future seismicdisturbances. Relying heavily on worldwide research associated with recentquakes, Seismic Design and Retrofit of Bridges begins with anin-depth treatment of seismic design philosophy as it applies tobridges. The authors then describe the various geotechnicalconsiderations specific to bridge design, such as soil-structureinteraction and traveling wave effects. Subsequent chapters coverconceptual and actual design of various bridge superstructures, andmodeling and analysis of these structures. As the basis for their design strategies, the authors' focus is onthe widely accepted capacity design approach, in which particularlyvulnerable locations of potentially inelastic flexural deformationare identified and strengthened to accommodate a greater degree ofstress. The text illustrates how accurate application of thecapacity design philosophy to the design of new bridges results instructures that can be expected to survive most earthquakes withonly minor, repairable damage. Because the majority of today's bridges were built before thecapacity design approach was understood, the authors also devoteseveral chapters to the seismic assessment of existing bridges,with the aim of designing and implementing retrofit measures toprotect them against the damaging effects of future earthquakes.These retrofitting techniques, though not considered appropriate inthe design of new bridges, are given considerable emphasis, sincethey currently offer the best solution for the preservation ofthese vital and often historically valued thoroughfares. Practical and applications-oriented, Seismic Design and Retrofit ofBridges is enhanced with over 300 photos and line drawings toillustrate key concepts and detailed design procedures. As the onlytext currently available on the vital topic of seismic bridgedesign, it provides an indispensable reference for civil,structural, and geotechnical engineers, as well as students inrelated engineering courses. A state-of-the-art text on earthquake-proof design and retrofit ofbridges Seismic Design and Retrofit of Bridges fills the urgent need for acomprehensive and up-to-date text on seismic-ally resistant bridgedesign. The authors, all recognized leaders in the field,systematically cover all aspects of bridge design related toseismic resistance for both new and existing bridges. * A complete overview of current design philosophy for bridges,with related seismic and geotechnical considerations * Coverage of conceptual design constraints and their relationshipto current design alternatives * Modeling and analysis of bridge structures * An exhaustive look at common building materials and theirresponse to seismic activity * A hands-on approach to the capacity design process * Use of isolation and dissipation devices in bridge design * Important coverage of seismic assessment and retrofit design ofexisting bridges

Book Deformation Characteristics of Geomaterials

Download or read book Deformation Characteristics of Geomaterials written by H. DiBenedetto and published by CRC Press. This book was released on 2005-03-03 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solutions for soil engineering and soil-structure interaction problems need realistic and pertinent experimental and modelling tools. In this work, extensive developments proposed by the invited speakers of the Lyon International Symposium held in September 2003 are presented, including experimental investigations into deformation properties; laboratory, in-situ and field observation interpretations; behaviour characterisation and modelling; and case histories. The contributions include recent investigations into anisotropy and non-linearity, the effects of stress-strain-time history, ageing and time effects, yielding, failure and flow, cyclic and dynamic behaviour. In addition, advanced geotechnical testing is applied to real engineering problems, and to ways of synthesising information from a range of sources while engaging in practical site characterisation studies.
