Examines structural aspects of high rise buildings, particularly fundamental approaches to the analysis of the behavior of different forms of building structures including frame, shear wall, tubular, core and outrigger-braced systems. Introductory chapters discuss the forces to which the structure is subjected, design criteria which are of the greatest relevance to tall buildings, and various structural forms which have developed over the years since the first skyscrapers were built at the turn of the century. A major chapter is devoted to the modeling of real structures for both preliminary and final analyses. Considerable attention is devoted to the assessment of the stability of the structure, and the significance of creep and shrinkage is discussed. A final chapter is devoted to the dynamic response of structures subjected to wind and earthquake forces. Includes both accurate computer-based and approximate methods of analysis.

Civil engineering structures such as buildings, bridges, stadiums, and offshore structures play an import role in our daily life. However, constructing these structures requires lots of budget. Thus, how to cost-efficiently design structures satisfying all required design constraints is an important factor to structural engineers. Traditionally, mathematical gradient-based optimal techniques have been applied to the design of optimal structures. While, many practical engineering optimal problems are very complex and hard to solve by traditional method. In the past few decades, swarm intelligence algorithms, which were inspired by the social behaviour of natural animals such as fish schooling and bird flocking, were developed because they do not require conventional mathematical assumptions and thus possess better global search abilities than the traditional optimization algorithms and have attracted more and more attention. These intelligent based algorithms are very suitable for continuous and discrete design variable problems such as ready-made structural members and have been vigorously applied to various structural design problems and obtained good results. This book gathers the authors' latest research work related with particle swarm optimizer algorithm and group search optimizer algorithm as well as their application to structural optimal design. The readers can understand the full spectrum of the algorithms and apply the algorithms to their own research problems.

Research studies on the preparation for and mitigation of future earthquakes, an area of increasing importance to many countries around the world, comprise this volume. The selected papers included in this book have been prepared by experts from around the world in the fields of earthquake engineering relevant to the design of structures. As the world's population has concentrated in urban areas resulting in buildings in regions of high seismic vulnerability, we have seen the consequences of natural disasters take an ever higher toll on human existence. Protecting the built environment in earthquake-prone regions involves not only the optimal design and construction of new facilities, but also the upgrading and rehabilitation of existing structures including heritage buildings, which is an important area of research. Major earthquakes and associated effects, such as tsunamis, continue to stress the need to carry out more research and a better understanding of these phenomena is required to design earthquake resistant buildings and to carry out risk assessment and vulnerability studies.

This book offers an integrated introduction to the topic of stability and vibration. Strikingly, it describes stability as a function of boundary conditions and eigenfrequency as a function of both boundary conditions and column force. Based on a post graduate course held by the author at the University of Southern Denmark, it reports on fundamental formulas and makes uses of graphical representation to promote understanding. Thanks to the emphasis put on analytical methods and numerical results, the book is meant to make students and engineers familiar with all fundamental equations and their derivation, thus stimulating them to write interactive and dynamic programs to analyze instability and vibrational modes.

Geotechnical failures, specially the catastrophic ones, are a stimulus to improve current understanding of phenomena and procedures and tools for analysis and prediction.

This unconventional approach to geomechanics is the essence of this book. In general, soil mechanics and geotechnical textbooks describe first the concepts and theoretical developments and then apply them to interpret or solve a particular applications. This book follows a different course. The case (a failure) is first described and then an explanation is sought. This requires a set of steps which can be summarized as follows: Identify the nature of the problem, develop a dedicated and specific formulation of the case, based on established basic concepts. In general, no single existing theory or procedure is available to solve the case at hand, provide a solution within an acceptable degree of complexity, extract the fundamental aspects of the problem and highlight its relevance.

The cases selected have been grouped into three main topics: Landslides, Embankments and Dams and Dynamics of Failures. Cases selected (Vaiont, Aznalcollar, Brattas-St. Moritz) are unique and illustrate a number of relevant and to some extent controversial issues which are of wide interest, without claiming exhaustive treatment of the subject.

The book teaches how to build the necessary models to understand the failures. Well established soil mechanics concepts are the necessary background. But the cases analyzed require in general a step ahead which is specific for the case analyzed. Balance and equilibrium equations are often required as a starting point. They are formulated at different scales, which are selected having in mind the abstract representation of each case.

Various chapters illustrate also the coupled nature (flow-deformation-temperature) of geotechnical problems and the need to properly address these complexities in some cases. In fact, temperature effects, a subject often neglected in conventional analyses, are necessary to explain some catastrophic landslides (Vaiont). In some of the chapters, specific calculation tools, included in well known and widely available programs (Excel, Maple ) have been used. Details of the ad hoc programs developed have also been included in Appendices to help the readers to follow the details of the calculation.

Finite element methods have not been used. In the landslides analyzed (Vaiont and Brattas-St. Moritz) currently available commercial programs are of limited utility. In the remaining cases the analysis performed provides a sufficient insight and interpretation of field behaviour.

Chapters include also a short description of the changes in the original design and the mitigation measures which could have prevented the failure. Also, a summary section of lessons learned is provided in all chapters. Finally, selected topics and more advanced reading are suggested.

This book is associated with a Master/Doctorate course being offered at the Department of Geotechnical Engineering and Geosciences of UPC, Barcelona. Potential readers therefore include Graduate and Master students, faculty and professionals in the fields of Civil and Geotechnical Engineering."

Science is for those who learn; poetry for those who know. -Joseph Roux This book is a continuation of my previous book, Dynamics and Control of Structures [44]. The expanded book includes three additional chapters and an additional appendix: Chapter 3, "Special Models"; Chapter 8, "Modal Actuators and Sensors"; and Chapter 9, "System Identification. " Other chapters have been significantly revised and supplemented with new topics, including discrete-time models of structures, limited-time and -frequency grammians and reduction, almo- balanced modal models, simultaneous placement of sensors and actuators, and structural damage detection. The appendices have also been updated and expanded. Appendix A consists of thirteen new Matlab programs. Appendix B is a new addition and includes eleven Matlab programs that solve examples from each chapter. In Appendix C model data are given. Several books on structural dynamics and control have been published. Meirovitch's textbook [108] covers methods of structural dynamics (virtual work, d'Alambert's principle, Hamilton's principle, Lagrange's and Hamilton's equations, and modal analysis of structures) and control (pole placement methods, LQG design, and modal control). Ewins's book [33] presents methods of modal testing of structures. Natke's book [111] on structural identification also contains excellent material on structural dynamics. Fuller, Elliot, and Nelson [40] cover problems of structural active control and structural acoustic control.

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 book is an engineering guide for design of slopes and stabilisation works in rocks and residual soils. It is tailored to the practising geotechnical engineer and engineering geologist. Engineering and engineering geology students will find it quite useful and a practical course guide. It can be used as textbook in courses on landslides and slope stabilisation. The book's purpose is to present a concise documentation on how to design slopes and how to select a slope stabilisation method. The authors were selected among those who have lots of experience in their field.

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."

This comprehensive new two-volume work provides the reader with a detailed insight into the use of the finite element method in geotechnical engineering. As specialist knowledge required to perform geotechnical finite element analysis is not normally part of a single engineering degree course, this lucid work will prove invaluable. It brings together essential information presented in a manner understandable to most engineers.Volume 1 presents the theory, assumptions and approximations involved in finite element analysis while Volume 2 concentrates on its practical applications.

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.

Tajikistan is one of the lesser-known and least-researched former Soviet Central Asian republics. The birth of the new state in 1991 was followed closely by a civil war which killed more than 50,000 people and displaced many tens of thousands more. While a peace agreement was signed in 1997, significant political violence continued until 2001 and intermittent outbreaks still occur today. Many claim it remains a very weak state and perhaps in danger of state failure or a return to civil war. However, the revival of Tajikistan should not simply be seen in terms of its post-conflict stabilization. Since its creation as a republic of the Soviet Union in 1920s, Tajikistan has been transformed from being a shell for socialist engineering to become a national society under a modern state. Despite a multitude of economic, social and political shocks, the Republic of Tajikistan endures. This book places the transformation of Tajikistan in its Soviet and Post-Soviet historical settings and local and global contexts. It explores the sources of a state with Soviet roots but which has been radically transformed by independence and its exposure to global politics and economics. The authors address the sources of statehood in history, Islam and secularism, gender relations, the economy, international politics and security affairs. This book is a new edition of a special issue of Central Asian Survey, 'Tajikistan: the sources of statehood', including two additional papers and a revised introduction.

A comprehensive guide to all legal and technical aspects of water boundaries.

"Water Boundaries" is a single-source guide to all critical legal and technical water boundary issues. An indispensable resource for surveyors, political geographers, public land managers, attorneys, developers, real estate professionals, and students in these and other related fields, this book provides: In-depth discussions of the legal issues surrounding all types of water boundariesThe full range of modern methods of precise water boundary locationDetailed technical specifications for mean high water line surveysRelevant algorithms and mathematical formulasIllustrative real-world case studies

Water boundaries are perhaps the oldest and most widely used of man's boundaries. Yet, despite this long history of usage, water boundaries are probably the most frequently and bitterly contested boundaries in today's society. Because shorelines and bodies of water are dynamic rather than static, knotty technical and legal disagreements over water boundaries invariably crop up. Recent land use practices have created a growing demand for precisely located and legally defensible water boundaries. As a consequence, the need for a single-source professional reference such as this has never been greater.

"Water Boundaries" is a comprehensive reference devoted exclusively to this highly specialized area. Written for surveyors and engineers, as well as legal and real estate professionals, it provides in-depth discussions of the legal issues surrounding each type of water boundary while describing the full range of modern methods for precisely locating them.

This volume covers all types of water boundaries, including division lines between private uplands and public submerged lands in both tidal and nontidal waters, lateral division lines between adjacent riparian ownerships, boundaries between state and federal waters, and offshore international boundaries.

For technical specialists, the author provides detailed specifications for mean high water line surveys, as well as all relevant mathematics, including formulas for calculating tidal data and predicting optimum placement of tide gauges, analytical techniques for estimating high water in nontidal bodies of water, and the use of coordinate geometry in constructing equidistant and median lines.

Technical and nontechnical readers alike will appreciate the many illustrative real-world case studies scattered throughout the book.

"Water Boundaries" is an indispensable resource for surveyors, public land managers, attorneys, developers, and real estate professionals, and for all those involved in land planning, offshore mineral extraction, and other related fields.

The dissolution of the communist system led to the creation of new states and the formation of new concepts of citizenship in the post-Soviet states of Central and Eastern Europe. The formation of national identity also occurred in the context of the process of increasing economic and political globalisation, particularly the widening of the European Union to include the central European post-socialist and Baltic States. Internationally, Russia sought to establish a new identity either as a European or as a Eurasian society and had to accommodate the interests of a wider Russian Diaspora in the 'near abroad'. This book addresses how domestic elites (regional, political and economic) influenced the formation of national identities and the ways in which citizenship has been defined. A second component considers the external dimensions: the ways in which foreign elites influenced either directly or indirectly the concept of identity and the interaction with internal elites. The essays consider the role of the European Union in attempting to form a European identity. Moreover, the growing internationalisation of economies (privatisation, monetary harmonisation, dependence on trade) also had effects on the kind of 'national identity' sought by the new nation states as well as the defining by them of 'the other'. The collection focuses on the interrelations between social identity, state and citizenship formation, and the role of elites in defining the content of concepts in different post-communist societies. This book was originally published as a special issue of Europe-Asia Studies.

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."

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.

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.

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.
