In the past decade, the field of trenchless technology has expanded rapidly in products, equipment, and utilization. This expansion would not have occurred without a strong increase ineconomic incentives to the user. Because theoperating environment has changed, trenchless technology is often the preferred alternative to traditional methods of digging holes and installing conduits. The infrastructure in which we live has become more congested and has to beshared by several users. In addition, the cost of restoring a road or landscaped area after construction may be higher than the cost of installing the conduit. These factors add to the need for trenchless technology-the ability to dig holes without disturbing the surface. In some ways, trenchless technology is a futuristic concept. Ruth Krauss in a children'sbookofdefinitions wrote,"AHole...Is to Dig." But thisstatement is not necessarily true. Today, a hole could be to bore. Trenchless technology is not new. But it certainly has become the buzzword of the construction industry and it appears that it will have a growing impact in the way contractors, utilities, and others install new facilities. Methods to bore horizontal holes were practiced as early as the 18005, but this technology has greatly changed. Today's tools include sophisticated drilling methods, state-of the-art power systems, and electronic guidance techniques. These tools can bore faster, safer, and more accurately, and in many instances more economically, than open-cllt methods. Technology has played an important role in these advances, but economics has become the driving force in making these systems popular."

Ferrocement is a versatile, construction material, with applications in low cost housing, rehabilitation, strengthening and repair of structures, especially in the developing world. The material can also be used in more advanced constructions for thin shell structures. This book forms the proceedings of the Fifth International Symposium on Ferrocement. It presents the latest developments in research and application of the material and should serve as a useful reference for all those interested in the material. This includes both researchers in all parts of the world, but also those responsible for low cost housing and construction in developing countries, in South America, Africa and the Far East. This book should be of interest to researchers concerned with building materials, government and international agencies involved with low cost housing, and repair specialists, consultants, contractors and material suppliers.

These proceedings document the various papers delivered and partially presented at the International Conference "From experimental evidence towards numerical modeling of unsaturated soils," which was held in Weimar (Germany) during 18-19 September 2003. The conference was organized under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) and the National German G- technical Society (DGGT). The need to understand the behavior of unsaturated soils is becoming exclusively - sential for the geotechnical engineers and designers. In the last three decades many - searchers have made significant contribution to the understanding of the unsaturated soil mechanics. Nevertheless, application of the subject to variety of new problems still - quires our attention. This International conference is a mere attempt to unite researchers and engineers in geotechnical engineering and to discuss about the problems associated with the unsaturated soils. Doing so the objectives of these lecture notes are as follows: - to promote unsaturated soil mechanics for practical application, - to exchange experiences in experimental unsaturated soil mechanics and numerical modeling, - to discuss application of unsaturated soil mechanics to variety of problems. In other words, we could also name these two volumes as "From theory to daily pr- tice." I would like to extend my deep sense of appreciation as the editor and the Head of the organizing committee, to many persons who have contributed either directly or indirectly to organize the International conference and to finalize these proceedings.

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.
It presents quantitative information and design methods in a useable form without recourse to extensive mathematical analysis. The authors, Peter Smith and John Hetherington, are staff members at the Royal Military College of Science in Shrivenham and have been instrumental in establishing an active group comprising lecturing and research staff concerned with the response of structures to blast and ballistic loading.

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.

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.

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

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.

Covers strata mechanics, numerical methods in geomechanics, water jet cutting and mechanical disintegration of rocks. The preface discusses the option of describing typical interdisciplinarity of geosciences, dealing with the processes induced by human activities in geospere, by the word geonics.

This book contains general recommendations for site clearing after man-made and natural disasters. It provides guidelines on the demolition of damaged structures and the reuse of demolition and construction materials. It has been prepared by an international task force originating from cooperation between RILEM and UNESCO. The book provides guidance for professionals and organizations on this increasingly important subject of disaster planning.

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.

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.

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.

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.

Covering common problems, likely failures and their remedies, this is an essential on-site guide to the behaviour of a building s structure.

It explains the structural behaviour of buildings, giving some of the basics of structures together with plenty of real-life examples and guidance.

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

The area of material damage models has undergone a rapid development in the past few years. This is an extensive and comprehensive survey of one- and three-dimensional damage models for elastic and inelastic solids. The state-of-the-art is reported by about 200 references. The book not only provides a rich current source of knowledge, but also describes examples of practical applications, numerical procedures, and computer codes. The style of presentation is systematic, clear, and concise and is supported by illustrative diagrams.

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 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
