The modeling of mechanical properties of materials and structures is a complex and wide-ranging subject. In some applications, it is sufficient to assume that the material remains elastic, i.e. that the deformation process is fully reversible and the stress is a unique function of strain. However, such a simplified assumption is appropriate only within a limited range, and in general must be replaced by a more realistic approach that takes into account the inelastic processes such as plastic yielding or cracking.

This book presents a comprehensive treatment of the most important areas of plasticity and of time-dependent inelastic behavior (viscoplasticity of metals, and creep and shrinkage of concrete). It covers structural aspects such as:

• incremental analysis

• limit analysis

• shakedown analysis

• optimal design

• beam structures subjected to bending and torsion

• yield line theory of plates

• slip line theory

• size effect in structures

• creep and shrinkage effects in concrete structures.

• yield surfaces for metals and plastic-frictional materials

• hardening and softening

• stress-return algorithms

• large-strain formulations

• thermodynamic framework

• microplane models

• localization of plastic strain.

This monograph provides the practising engineer with a concise overview of the methods of water diversion and exclusion or removal of sediment from the diverted water. The emphasis is on flow features and the associated conveyance of sediments.

Structural concrete, although durable, often needs repairing. Impact, abrasion, overloading, fire and aggressive environments all cause damage, and cracks appear, due to errors in design or specification and faulty construction. This text enables the engineer to diagnose the cause of a fault, choose the appropriate remedial technique and ensure that the repair work is completed satisfactorily. It will be of value to all those who need to commission, supervise or carry out repairs to concrete structures.

New materials and methods within the construction industry offer substantial advantages in terms of cost, durability, ease of design, and ease of fabrication. This new book looks at the multitude of uses of polymer composites in construction and discusses fabrication methods, suitability of materials, design methods, construction methods, performance and practical applications.

Treating anchorages as a direct application of the laws of statics and the theories governing the transfer of load, this book focuses on designs that are safe and reasonably priced. It is divided into two parts. Following a general introduction in the first chapter, Part One goes on to explore anchor systems, components, installation and construction details. Presents special anchor systems such as extractable, compression-type, multibell, and regroutable anchors. Analyzes the transfer of load and its relation to failure modes and anchor load capacity; deals with design considerations; covers mechanisms and types of corrosion; and details anchor stressing, testing programs, and evaluation standards. Part Two considers uses and applications and design aspects of anchored structures; presents design examples of practical value and reasonable simplicity; and incorporates examples and case histories.

High performance concrete (HPC) is of great topical interest to the construction industry worldwide, with applications in high-rise, offshore, nuclear and bridge structures, and in precast concrete. Among the benefits of HPC are improved workability and strength, leading to faster and more economical construction; more durable concrete, especially important for bridges, offshore and nuclear structures, and highways; and improved structural characteristics, which allow more economical and efficient structural designs. The French national project, "New Developments for Concrete", is providing important insights into the materials characteristics of high performance concrete, and also of the structural behaviour of a number of major buildings and bridge structures. This book contains a series of 35 selected reviews and reports on HPC by the leading materials scientists and engineers contributing to the French programme. Previously, they have only been available to delegates at seminars and meetings in France but the most valuable have been edited and translated into English in order to make the results of the programme widely available.

New developments in the response spectrum method have led to calculations in seismic stresses that are more accurate, and usually lower, than those obtained by conventional methods. This new textbook examines the wealth of information on the response spectrum method generated by the latest research and presents the background theory in simplified form.
Applications of these methods is essential in the seismic design of critical structures, such as nuclear power plants and petroleum facilities. In new construction, the reduced seismic stresses will result in efficient and economic design. For facilities already built, these more accurate methods can be used where the facility is being reassessed for higher loads and in the calculation of margins.
Written by an acknowledged expert in this and related fields, this volume is ideal as a graduate text for courses in structural and earthquake engineering. It is also an excellent reference for civil, structural, mechanical, and earthquake engineers.

The assessment of structural integrity is a vitally important consideration in many fields of engineering, which has an influence on the full range of professional activities from conception, design and analysis, through operation to residual life evaluation and possible life extension. In devising satisfactory procedures for this purpose there is a clear need for interaction and information exchange across this broad spectrum of activities. This conference provided the forum for this exchange of expertise and knowledge among engineers from diverse professional backgrounds and disciplines. The conference was run under the auspices of the Engineering Integrity Society and the Dynamic Testing Agency and was co-sponsored by the British Society for Strain Measurement, the Department of Trade and Industry, the Institution of Mechanical Engineers, the Joint British Committee for Stress Analysis and the National Agency for Finite Element Methods and Standards. The papers presented are relevant to practitioners in power generation, aerospace, transport, offshore, process and construction engineering.

Provides therapists with an understanding of the principles, applications and implications of paradoxical therapy, the rationale for the use of paradox in family therapy and the therapist's role in paradoxical interventions.

The papers and discussions deal with various types of shear walls, nuclear containment structures, high rise buildings, box bridges, l-girders, columns and shells. They represent early 1990s knowledge of concrete shear in earthquake.

An increasing number of buildings require informed decisions to be made about their continued safety and serviceability. Although social and economic issues are often all-important influences, the technical factors nevertheless need to be addressed objectively, efficiently and reliably. The aim of this book is to bring together those techniques which can be used effectively to monitor building structures. Emphasis is given to reliability, practicality, cost-effectiveness and the use of relevant examples. Written primarily for practising engineers responsible for the assessment of safety and serviceability, and for the client specifying a brief for an assessment or evaluating a report, this book should also serve as a source of reference for those in research involving monitoring, and as an aid to the student requiring a better understanding of the full-scale performance of building structures.

The science of the study of containers of various materials has, in the majority of cases, a uniformity of shape, of function and of loading. The grouping of the papers in this publication lift the barriers and give the state of the art for each sector. More than 50 articles are grouped by theme.

With current moves towards international harmonization, there is a need for rationalization and standardization of test procedures and interpretation of test results in many fields. Testing of metals for use in structures, particularly steel and aluminium, is a subject where information on these aspects is generally lacking. In response to this, RILEM (The International Union of Testing and Research Laboratories for Materials and Structures) organized an international workshop to identify "need in testing metals". Invited experts from Europe, Japan and the USA have contributed papers not only on experimental procedures for testing metallic materials, joints and structural components, but also on analytical models for interpreting their behaviour and for use in calculations. The papers brought together in this book provide reviews of the current situation and signposts for future research and development needs. In response to the recommendations of the workshop, RILEM is setting up new international committees and initiatives on the behaviour of joints, high cycle fatigue, non-destructive testing, structural imperfections, composite and thin-walled structures. This book should be va

This volume consists of papers presented at the International Conference on Earthquake, Blast and Impact held at the University of Manchester Institute of Science and Technology, UK, 18-20 September 1991, organised by the Society for Earthquake and Civil Engineering Dynamics (SECED) and supported by the Institution of Civil Engineers, the Institution of Mechanical Engineers and the Institution of Structural Engineers.

Fly ash is an important industrial by-product, with more 170 million tonnes produced annually throughout the world. It is the fine particulate material which is collected from the stack gases of power stations burning pulverized coal and it is being increasingly used as a partial replacement for cement in concrete and other cement-based onstruction materials. Substantial research and development programmes in many parts of the world are being undertaken to investigate the properties and performance of fly ash in concrete, to ensure satisfactory, economic utilization. This book s a report on the subject, complied under the auspices of RILEM, the International Union of Testing and Research Laboratories for Materials and Structures. In the first chapter, the characterization and properties of fly ash in relation to the coal and burning conditions in the power station are described. The behaviour of fresh mortar and concrete is covered next. A major part of the book deals with hardened mortar and concrete, and covers hydration, strength, deformations, frost resistance, chemical resistance and carbonation, with special attention given to the deformation behaviour of fly ash concretes.

Concrete is one of the principal construction materials used world-wide. Although developments in materials and performance have widened the scope for the use of concrete, they have also affected its properties, particularly in the long term. From this it becomes clear that quality control, which is of vital importance for the building industry in general, needs special attention in its application to concrete structures. The importance of establishing comprehensive quality assurance systems both nationally and internationally is becoming increasingly recognized. Such systems need to take account of the contractual relationships in the industry in order to function effectively. International harmonization of standards and regulations is also putting greater emphasis on such systems. This book forms the proceedings of the Second International Symposium on Quality Control of Concrete Structures which was held in Ghent, Belgium, in June 1991. The volume brings together new information on technical developments, research and practical experience on the following topics: quality management, early age properties of concrete, durability, quality assessment, statistical approaches.

This text contains 28 papers from 12 countries that reflect the current state-of-the-art in the early 1990s of: modelling in loading, fatigue and IMR strategy, and more than 50 per cent of the papers originate from authors based in industry or government departments. The book should be of interest to those working in a wide range of industries such as oil company operators, consultants, certification authorities, construction firms, as well as academics, government departments and laboratories.

This volume sets out to present recent research findings on the applications of fracture mechanics to concrete structures. Papers from international contributors describe existing and new modelling techniques in the analysis of concrete materials and structures. Topics discussed include structural modelling, bending, shear, bond and anchorage. The book forms the proceedings of a RILEM workshop held in Sweden in 1989. It is dedicated to Professor Arne Hillerborg, whose contribution to fracture mechanics is also reviewed.

The book systematically presents variational principles and methods of analysis for applied elasticity and structural mechanics. The variational approach is used consistently for both, constructing numerical procedures and deriving basic governing equations of applied mechanics of solids; it is the derivation of equations where this approach is most powerful and best grounded by mathematics.

Manynationshavebecomevictimsofterrorism. Bombshaveexplodedinand around buildings and other structures. Such events have generated cons- erable concern over the ability of countries and governments to protect - stallations and their occupants against a potential threat of terrorism. Many countries have established defence agencies and research councils who are currently examining the structural integrity of existing buildings and other vital installations. In some countries codi?ed methods have been developed together with the design methodologies and construction techniques to try to protect old installations against vehicle bomb e?ects in particular. The purpose of this book is to give an exhaustive study of buildings structures resistingexplosion with and withoutexternal/internalimpactand ?recaused by such e?ects. A number of case studies with damage scenarios are included. The book is divided into various chapters. Chapter 1 gives a review of bomb-a?ected buildings. Case studies incl- ingAlfred P. Murrah Federal Building in Oklahoma and World Trade Center (WTC) Twin Towers in New York have been given a wide coverage. Notable explosionsintheworldwithrelevantdataaretabulated. Afterthesethed- age scenario of the Pentagon building is fully described. This chapter now resorts to the availability of data on major explosive elements, their ingre- ents and material properties.

The second edition of this book provides structural engineers with a concise introduction to the architectural, structural and technological aspects of cable roofs, and supplies sufficient information for engineers to carry out their own designs. The improved methods for generating wind and earthquake histories have been included as the trend in modern design codes seem increasingly to require that dynamic response of other forms of non-linear structures such as guyed masts is considered at the design stage.

Since the first edition of this book was published, most developments in welding construction have been within the quality assurance element of the process rather than in welding technology itself. The continuous pressures from worldwide clients seeking better reliability from welded structures has focused much attention on to quality. The quality characteristic has a significant effect on safety and economy, and the never ending attention to cost effectiveness requires continuous attention to quality control and quality assurance. New materials, faster welding methods and the needs of economic design mean that such objectives must be carefully studied during the planning and execution of welded work. Quality Assurance in Welded Construction covers the essential aspects of the area, and is suitable for civil and structural engineering designers, welding engineers, manufacturing managers, inspectors and QA personnal. Included in the book are features and illustrations relating to defects in welded construction, a summary of essential data, and a substantial amount of information to assistin the task of getting welded structures right first time.

This book is written by subject experts based on the recent research results in steel plate shear walls considering the gravity load effect. It establishes a vertical stress distribution of the walls under compression and in-plane bending load and an inclination angle of the tensile field strip. The stress throughout the inclined tensile strip, as we consider the effect of the vertical stress distribution, is determined using the von Mises yield criterion. The shear strength is calculated by integrating the shear stress along the width. The proposed theoretical model is verified by tests and numerical simulations. Researchers, scientists and engineers in the field of structural engineering can benefit from the book. As such, this book provides valuable knowledge, useful methods, and practical algorithms that can be considered in practical design of building structures adopting a steel shear wall system.

This book examines the structural and construction design of buildings. The first part presents an overview of materials and structural forms taking the point of view of the designer, architect and engineer.
