Leading international researchers and practitioners of bifurcations and instabilities in geomechanics debate the developments and applications which have occurred over the last few decades. The topics covered include modeling of bifurcation, structural failure of geomaterials and geostructures, advanced analytical, numerical and experimental techniques, and application and development of generalised continuum models etc. In addition analytical solutions, numerical methods, experimental techniques, and case histories are presented. Beside fundamental research findings, applications in geotechnical, petroleum, mining, and bulk materials engineering are emphasised.

This text is an introduction to the dynamics of active structures and to the feedback control of lightly damped flexible structures; the emphasis is placed on basic issues and simple control strategies that work.

Now in its third edition, more chapters have been added, and comments and feedback from readers have been taken into account, while at the same time the unique premise of bridging the gap between structure and control has remained. Many examples and problems bring the subject to life and take the audience from theory to practice.

The book has chapters dealing with some concepts in structural dynamics; electromagnetic and piezoelectric transducers; piezoelectric beam, plate and truss; passive damping with piezoelectric transducers; collocated versus non-collocated control; active damping with collocated systems; vibration isolation; state space approach; analysis and synthesis in the frequency domain; optimal control; controllability and observability; stability; applications; tendon control of cable structures; active control of large telescopes; and semi-active control. The book concludes with an exhaustive bibliography and index.

This book is intended for structural engineers who want to acquire some background in vibration control; it can be used as a textbook for a graduate course on vibration control or active structures.

A solutions manual is available through the publisher to teachers using this book as a textbook.

This book discusses the application of independent continuous mapping method in predicting and the optimization of the mechanical performance of buckling with displacement, stress and static constrains. Each model is explained by mathematical theories and followed by simulation with frequently-used softwares. With abundant project data, the book is an essential reference for mechanical engineers, structural engineers and industrial designers.

This book contains papers presented at the 1st International Conference on Timber Structures, which was held in collaboration with the Technical Centre of Wood Industry in Belgium. It explores the latest developments in wood products and their application as structural components. The focus of the included works is to draw attention to new research and real applications from both researchers and practitioners, and to present new and innovative ideas in this significant field. Rapid advances have recently been made in the development and processing of innovative ecologically friendly wood products. A variation of new structural shapes can now be fabricated and used to construct buildings and bridges that have minimal impact on the environment. Wood is particularly appealing since it is renewable and has no carbon footprint when it is harvested in a sustainable way. Timber structures are ecologically sound and comparatively low cost. The material lends itself to ground-breaking designs and new types of composites offer reliable, robust and safe materials. The content of this book comprises a range of topics: Material properties of wood; Durability aspects, service life modelling; Fire safety of timber structures; Protection against decay; Non-destructive inspection and monitoring; Glued, laminated structures, Xlam and CLT; Timber joints and connections; Vernacular wood and heritage timber structures; Timber housing and eco-architecture; Timber bridges; Large span timber roof structures; Shell structures in timber; Mixed, composite and hybrid structures; Computational analysis and experimental methods; Structural engineering and design; Seismic behaviour of timber structures; Protection of timber; Repaired timber structures; Rapidly assembled and transferable timber structures; Guidelines, codes and regulations; Structural failures; Art and craftsmanship.

This book provides a State of the Art Report (STAR) produced by RILEM Technical Committee 254-CMS 'Thermal Cracking of Mas-sive Concrete Structures'. Several recent developments related to the old problem of understanding/predicting stresses originated from the evolution of the hydration of concrete are at the origin of the creation this technical committee. Having identified a lack in the organization of up-to-date scientific and technological knowledge about cracking induced by hydration heat effects, this STAR aims to provide both practitioners and scientists with a deep integrated overview of consolidated knowledge, together with recent developments on this subject.

Virtual worlds are places where humans interact, and as such they can be environments for research and learning. However, they are complex and mutable in ways that more controlled and traditional environments are not. Although computer-mediated, virtual worlds are multifaceted social systems like the offline world, and choosing to study virtual world phenomena demands as much consideration for the participants, the environment and the researcher as offline. By exploring virtual worlds as places of research and learning, the international practitioners in this book demonstrate the power of these worlds to replicate and extend our arenas of research and learning. They focus on process and outcomes and consider questions that arise from engaging in teaching and research in these spaces, including new approaches to research ethics, internationalization, localization, and collaboration in virtual worlds. This book was originally published as a special issue of Learning, Media & Technology.

This volume includes the papers presented at the North American Tunneling 2002 Conference. The papers deal with three major aspects of underground construction: managing construction projects; public policy and underground facilities; and advances in technology.

Any practitioner who takes his profession in earnest, such that daily work is not a heavy duty but part of their life, will recognize in this book the rigorousness of the analysis and the comprehensive presentation of the problems. This professional attitude is solely able to make the research and design engineer deal with strength structures and their behaviour. Indeed, the computational means that are nowadays available permit the numerical computation of whatever problem; the pro gram libraries are extremely rich and programs themselves have developed intensively. Howeyer, though computers are available at any moment without restrictions on the frequency with which they are employed, they finally impoYerish the creative compe tency of the civil engineer. Thus, he will calculate increasingly more while devising increasingly less. He will draw less and less on the experience gained in devising and implementing bearing structures because the computational process can be repeated as often as desired over a minimum time-period by means of the available programs. \Ve note that nowadays structures are no longer investigated or economically designed to comply with the requirements of the topic of interest.: Much to the contrary, the solutions are chosen so as to comply with the capabilities of the programs. A bearing structure lives as is prescribed by its initial con structive data."

The editors would like to express their sincerest appreciation to all of the anonymous reviewers all over the world, for their diligent work.

Concrete is an integral part of twenty-first century structural engineering and an understanding of how to analyze and design concrete structures is a vital part of your training as a structural engineer. With eurocode legislation increasingly replacing British Standards it 's also important to know how this affects the way you can work with concrete.

Newly revised to Eurocode 2, this second edition retains the original 's emphasis on qualitative understanding of the overall behaviour of concrete structures. Now expanded, with a new chapter dedicated to case studies, worked examples and exercise examples it 's an even more comprehensive guide to conceptual design, analysis and detailed design of concrete structures.
The book provides civil and structural engineering students with complete coverage of the analysis and design of reinforced and prestressed concrete structures. Great emphasis is placed on developing a qualitative understanding of the overall behaviour of structures.

Geotechnical instrumentation is used for installation, monitoring and assessment on any sizeable project, particularly in urban areas, and is used for recording, controlled remedial work, and safety.

This unique and up-to-date book deals with the conceptual philosophy behind the use of instruments, and then systematically covers their practical use. It is divided into displacement dominated systems and stress recording systems. The limitations are discussed and the theoretical background for data assessment and presentation are covered in some detail, with some relevant background material in theoretical soil mechanics. Relevant advanced electronic techniques such as laser scanning in surveying and fibre-optics are also included and communication and data recovery systems are discussed.

It is written for senior designers, consulting engineers and major contractors who need a major introduction to the general purpose, availability and analysis of field instruments before details of their own project can be progressed, and serves as a text book to any specialist geotechnical MSc or professional seminar course in which instrumentation forms a major part.

Non-Destructive Testing (NDT) techniques for the inspection of industrial structural components have to be qualified in respect to the minimum performance to be achieved. The qualification schemes relate to all aspects of the tests: procedure, equipment and personnel and the qualification of inspection should be codified in Standards. Such Standards are of two main types: those that detail the methods and procedures to be used and those that define the results which must be achieved. The European Network for Inspection Qualification (ENIQ) has as its aim the creation of a European collaboration for critical studies, assessment and qualification of inspection procedures for industrial structural components. The final goal is to support international Codes and Standards bodies via technical tools, expertise and demonstrative exercises that can be sponsored and managed at the European level.

The piling industry has, in recent years, developed a variety of press-in piling technologies with a view to mitigate noise & vibration nuisance. This book focuses on the "Walk-on-Pile" type press-in piling system, which offers an alternative engineering solution for piling works. This type of piling has unique features, including the application of the compact piling machine using pre-installed piles as a source of reaction force to jack in a new pile by hydraulic pressure. Moreover, the machine can walk along the top of piles already installed, thus enabling piling in a limited space and headroom with minimum disruption to social functions and services of existing infrastructure. These features are opening up a new horizon in piling, leading to novel application of embedded walls previously considered impossible. This introductory book provides a historical development of press-in piling and various challenging applications worldwide as well as scientific research outcomes, forming a valuable source of reference for readers who are unfamiliar with press-in piling, including project owners, design engineers, practical engineers as well as researchers and students.

For undergraduate courses in Steel Design. * Both Load and Resistance Factor Design (LRFD) and Allowable Stress Design (ASD) methods of designing steel structures are presented throughout the book.

Piled foundations are generally designed using empirical methods, in particular the traditional capacity based approach on which the majority of codes of practice are based. However in recent years the analysis of pile groups and piled rafts has undergone substantial development in the light of new research and the mechanisms for the interactions between piles, soil and rafts or caps have been largely clarified. Paradoxically, with relatively large piled rafts it has been found that a design based on the criterion of serviceability, with the limitation of absolute and/or differential settlement, not only allows a more rational and economical design, but is also simpler and more reliable than one based on the traditional approach.

This book provides an overview of present design practice of piled foundations, under both vertical and horizontal loads, and then a presentation of recent advances in the analysis and design of piled rafts. Altogether it forms a thorough guide to the design and analysis of efficient and effective piled rafts, and it also serves as a useful design handbook for traditional pile foundations.

Intended for structural engineers, this third edition text, a source on the use of matrix analysis for structures of all types, has been revised and updated.

The main advantages of sandwiches as structural components are now well known and well-established. Due to the progress in polymer science and engineering and advances in manufacturing processes, sandwich structures can blend various functional and structural properties and therefore lead to highly innovating systems. The current difficulty to overcome is to provide designers with proper methodologies and tools that could enable them to design improved sandwich structures. Such dedicated design tools should be efficient, reliable, flexible and user-friendly. They should be based on advanced knowledge of sandwich behaviour at global and local scales. Such approach relies on our capability to test, identify, control and model structure performances. The impressive variety of core and face materials and the rapid developments in forming processes give new opportunities to design components which have more complex shapes and higher integrated functional and structural properties. Interest in sandwiches is permanently growing in industry and refined testing and modelling approaches should be encouraged to set up relevant guidelines to design reliable advanced structures. The European Society for Mechanics sponsored the EUROMECH 360 Colloquium on the 'Mechanics of Sandwich Structures' in Saint-Etienne, France, on 13 - 15 May 1997. The main purpose of EUROMECH 360 was to go into the most recent progresses in sandwich analysis and design, including mechanical modelling and testing. It was expected that the Colloquium should contribute to define new research directions to support development of advanced applications in strategic industrial sectors such as ground transportations or building and civil engineering."

Design practice in offshore geotechnical engineering has grown out of onshore practice, but the two application areas have tended to diverge over the last thirty years, driven partly by the scale of the foundation and anchoring elements used offshore, and partly by fundamental differences in construction and installation techniques. As a consequence offshore geotechnical engineering has grown as a speciality. The structure of Offshore Geotechnical Engineering follows a pattern that mimics the flow of a typical offshore project. In the early chapters it provides a brief overview of the marine environment, offshore site investigation techniques and interpretation of soil behaviour. It proceeds to cover geotechnical design of piled foundations, shallow foundations and anchoring systems. Three topics are then covered which require a more multi-disciplinary approach: the design of mobile drilling rigs, pipelines and geohazards. This book serves as a framework for undergraduate and postgraduate courses, and will appeal to professional engineers specialising in the offshore industry.

This second edition of Reese and Van Impe's book has been extensively revised to be compatible in the classroom setting. New features include homework problems with solution aides presented by the student version of the software as well as new case studies and updated existing case studies that agree with modern methods of characterizing soil properties. The thrust of the book is a detailed presentation of methods of analysis for single piles and groups of piles under lateral loading. The method makes use of load-transfer functions that are based heavily on testing results of full-scale, heavily instrumented piles under carefully controlled lateral loading, coupled with the use of soil-structured interaction mechanics. This method is validated by comparing the results from the method of analysis with experimental results from case studies of un-instrumented piles. The book specifically addresses the analysis of piles of varying stiffness installed into soils with a variety of characteristics, accounting for the axial load at the top of the pile and for the rotational restraint of the pile head, possibly nonlinear, offered by the connection to the superstructure. The text provides example designs as well as the design of pile foundations that support an offshore platform. The book also includes references to a rich body of technical material, including citations of hundreds of relevant publications. The user may find the material on pile groups under lateral loading to be particularly helpful. The method begins with the loading at the foundation origin and makes use of nonlinear pile-head functions for the lateral load, the axial load, and the moment, taking pile-soil-pile interaction into account. For two-dimensional cases, the rotation and displacement of the foundation origin is computed to achieve equilibrium, and the resulting pile-head loading may be computed. Results for different loadings can also be readily calculated to seek t

This book will appeal to specialist engineers with enquiring minds and, in a broader sense, to all who live in buildings, especially those in a seismically active region. While the continual development of building codes permits the design of new construction to resist earthquake loads more effectively, a major problem is that buildings which may once have conformed to past seismic codes become structurally unacceptable according to today's codes and need upgrading or retrofitting'. Poor construction methods also result in buildings that do not conform to any codes. Existing vulnerable' buildings that require strengthening in earthquake-prone countries immensely outnumber all recent construction.
The health' of buildings thus requires assessment and rehabilitation. Seismic assessment ranges from the cataloguing of danger symptoms' in individual buildings to structural analyses involving finite element procedures and refined statistical analyses incorporating expert systems, stochastic processes and predictions from available databases. Structures have to be rendered fit for earthquakes, and this book goes a long way towards showing why and how, offering the results of cutting-edge research in the area and presenting innovative methods that enable system improvement while the structure remains in use.

This book was developed while I was teaching graduate courses on analysis, design and optimization of structures, in the United States, Europe and Israel. Structural analysis is a main part of any design problem, and the analysis often must be repeated many times during the design process. Much work has been done on design-oriented analysis of structures recently and many studies have been published. The purpose of the book is to collect together selected topics of this literature and to present them in a unified approach. It meets the need for a general text covering the basic concepts and methods as well as recent developments in this area. This should prove useful to students, researchers, consultants and practicing engineers involved in analysis and design of structures. Previous books on structural analysis do not cover most of the material presented in the book. The book deals with the problem of multiple repeated analyses (reanalysis) of structures that is common to numerous analysis and design tasks. Reanalysis is needed in many areas such as structural optimization, analysis of damaged structures, nonlinear analysis, probabilistic analysis, controlled structures, smart structures and adaptive structures. It is related to a wide range of applications in such fields as Aerospace Engineering, Civil Engineering, Mechanical Engineering and Naval Architecture.
