Soils formed or now existing under arid climatic conditions cover more than one-third of the world's land surface. Many have unique characteristics which can pose difficult geotechnical problems. This text considers these problems and suggests ways of overcoming them.
It brings together, in a concise format, the key elements of the
loads produced from explosive sources, how they interact with
structures and the way structures respond to them. Explosive
sources include gas, high explosives, dust and nuclear
materials.
This book forms the Proceedings of the International Seminar held by the Institution of Structural Engineers and the Building Research Establishment in Brighton in April 1993. It brings together contributions from 15 countries on recent innovations in building and construction. Developments in the design of structures, improvements in existing materials and the introduction of new materials have historically gone hand-in-hand. The limited range of materials available for construction at any one time dictates the practical range of structural form and performance. It follows that current design methods, materials and construction techniques may not be suitable to meet the demands of particular applications. The introduction of a new material, or new practice may move the performance of the construction away from that which is reasonably well understood in the existing population of structures. By so doing, it may also lead to behaviour which cannot be adequately predicted by the current design methods. Developments such as these therefore bring risks as well as benefits. Innovations required to meet the clients' needs can also have a profound effect on the built environment. It is i
The need for demolition, repair and renewal of concrete and masonry structures is growing all over the world. In recent years natural disasters, such as earthquakes, and war activities in many countries have caused very extensive damage to urban areas. This has led to the need for effective methods of assessing structural damage, site clearance and reconstruction. This book presents and discusses worldwide technical developments in the fields of demolition and recycling. The necessary theoretical technical background has accumulated, but knowledge is not being translated into practice. In particular, information is needed on standards and guidelines to promote quick and safe demolition and reuse of concrete and masonry. RILEM has been actively involved in this field for over ten years, through the work of its Technical Committees and the organization of International Symposia. This book forms the Proceedings of the Third Symposium, held in Odense, Denmark in October 1993, and follows the earlier events in Rotterdam in 1985 and Tokyo in 1988. The book will be invaluable for civil engineers, planners, contractors and researchers, and for government authorities and specialists in urban development and disaster mitigation.
Geotechnical Engineering treats the mechanics of soils and structures interacting with soils. Its primary aim is to reach undergraduate students, however, as it also discusses the more advanced aspects of soil behaviour, it will also appeal to graduate students. Furthermore, practicing engineers who are in search of a rational introduction to the behaviour of foundation structures will find this work a valuable aid. The three areas contributing to a successful teaching of geotechnical engineering are covered: applied mechanics; tests and experiments; and observation. A list of more than 450 selected references has been added for those readers who wish to study specific topics in more detail.
Corrosion of steel reinforcement in concrete is a major problem, with serious implications for structural integrity and durability. Bridges and marine structures are particularly susceptible due to the more chemically aggressive environmental conditions that prevail. Hence there is a need to examine the durability, strength characteristics and suitability of alternative materials to steel reinforcement. This book provides a thorough overview of recent developments and applications in this area of growing importance. This book should be of interest to structural and civil engineers involved in the design and construction of concrete structures; materials researchers investigating durability and strength of reinforcing materials; and advanced students in these fields.
Designed for engineers, this work considers flow-induced vibrations. It covers topics such as body oscillators; fluid loading and response of body oscillators; fluid oscillators; vibrations due to extraneously-induced excitation; and vibrations due to instability-induced excitation.
Lightweight aggregate concrete is undergoing something of a renaissance. Although this material has been available for many years, only now is it being used more widely. The volume of structural aggregate concrete used each year is increasing dramatically. Lower structural weight, better fire resistence, use of waste for aggregate, lower costs for aggregate: all these factors are contributing to the rapid increase in the use of acceptance of structural lightweight aggregate concrete. This book provides a comprehensive review of this growing field from an international perspective. This book should be of interest to structural and civil engineers involved in the design and construction of concrete structures; researchers in concrete materials design and performance.

Poor soil conditions are usually associated with excess groundwater or inadequate strength, which leads to excessive deformation or failure. Improvement of the soil may be needed temporarily, while construction operations lasr, or permanently. The same techniques are applicable all over the world. This book reviews the techniques which are used to improve the engineering behaviour of soils, either in situ or when they are used as a construction material. This illustrated account includes up-to-date references. "Engineering Treatment of Soils" may be valuable for geotechnical engineers working in professional firms and academic institutions all over the world. Many of the techniques are specialized and the contents of the book could be usseful for civil engineers, engineering geologists and mining engineers unfamiliar with them and for students and young engineers.
This text presents the most recent research on fracture and damage of concrete and rock. It provides an improved understanding of the basic physical and mechanical principles of fracture mechanics in these materials with a strong view towards applications in construction engineering and mining engineering. It forms the proceedings of the international conference held in Vienna in November 1992. The background to the book comes from three main areas: fatigue and ageing of complex concrete structures have been responsible both for loss of life and for expenditure running into billions of dollars in recent decades; lack of virgin building land and high property values in cities and urban areas have led to more demolition and recycling of concrete structures, and related environmental problems; and more engineering structures are being built on and in rock mass of low quality and difficult terrain. Rock fracture mechanics has matured to a fully recognized discipline and is now being applied to problems of excavation, tunnelling, blasting and anchoring. FDCR Conferences provide a forum for international, interdisciplinary co-operation and exchange of ideas and experience between scienti
This book contains 12 chapters which were presented as invited lectures at the Third International Symposium on Structural Crashworthiness held at the University of Liverpool, England, 14-16 April, 1993. This symposium was a logical continuation and extension of two previous Symposia held in 1983 and 1988, organized in order to examine recent developments in structural crashworthiness and failure. Particular emphasis has been given in this book to the failure predictions for ductile metal structures under large dynamic loads and to the behaviour of composite and cellular structures. Thus, it is likely that the field of structural crashworthiness and failure will continue to grow in importance. It is also evident from this book that much has already been achieved, but areas are highlighted in which further understanding of the basic mechanics is still required as well as the generation of design methods and design data. Chapters one to four focus on the failure of ductile metal structures, and chapter five examines a related topic on the perforation of metal tubes. Chapter six to eight examine the behaviour of non-metal structures subjected to various large dynamic loads. Chapter ni

The English edition includes an updated state-of-the-art review.
The proceedings of the 2nd International Scale Effects in Rock Masses, held in Lisbon, June 25, 1993. The text includes coverage of scale effects in the determination of the deformability and strength of rock masses and scale effects in the determination of internal rock masses.
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.
This is a comprehensive guide to autoclaved aerated concrete (AAC) for designers, specifiers, users and manufacturers. It provides a model code of practice for the structural use of AAC and provides designers with a complete guide to the structural use of AAC in structural applications in building. The second part contains the complete suite of RILEM Recommendations for specification and testing of AAC. Recommendations for further research, structural design examples and a glossary of terms are also included. The book has been prepared by two international groups of specialists under the auspices of RILEM (The International Union for Testing and Research Laboratories for Materials and Structures). This book should be of interest to architects and structural engineers working in professional practices, as well as building contractors, researchers, manufacturers and testing authorities.
HAPM Component Life Manual has broken new ground, it is the first document to provide extensive life-span assessments (suitable for insurance purposes) for a wide range of building components which are classified within the concept of quality specifications. A further benefit is that it does not seek to be prescriptive. It indicative 'benchmarks' against which new or differing specifications can be assessed, in that sense it is both robust and flexible. The concept of the manual is simple yet profound. Seven component groups contain a range of component types and sub-types each of which has been given a life class designation. The life classes embrace good practice, a normal amount of maintenance and typical exposure conditions. If a new component does not match an existing HAPM class, then a new 'benchmark' can be defined and a life assigned.
A review of open channel turbulence, focusing especially on certain features stemming from the presence of the free surface and the bed of a river. Part one presents the statistical theory of turbulence; Part two addresses the coherent structures in open-channel flows and boundary layers.
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.
Important developments in the progress of the theory of rock mechanics during recent years are based on fractals and damage mechanics. The concept of fractals has proved to be a useful way of describing the statistics of naturally occurring geometrics. Natural objects, from mountains and coastlines to clouds and forests, are found to have boundaries best described as fractals. Fluid flow through jointed rock masses and clusterings of earthquakes are found to follow fractal patterns in time and space. Fracturing in rocks at all scales, from the microscale (microcracks) to the continental scale (megafaults), can lead to fractal structures. The process of diagenesis and pore geometry of sedimentary rock can be quantitatively described by fractals, etc. The book is mainly concerned with these developments, as related to fractal descriptions of fragmentations, damage and fracture of rocks, rock burst, joint roughness, rock porosity and permeability, rock grain growth, rock and soil particles, shear slips, fluid flow through jointed rocks, faults, earthquake clustering, and so on. The prime concerns of the book are to give a simple account of the basic concepts, methods of fractal geometry, and their applications to rock mechanics, geology, and seismology, and also to discuss damage mechanics of rocks and its application to mining engineering. The book can be used as a textbook for graduate students, by university teachers to prepare courses and seminars, and by active scientists who want to become familiar with a fascinating new field.
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.
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.
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.
