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.

The integration of photovoltaics (PV) into buildings goes beyond energy saving by providing a clean and elegant way of actually generating electricity. There are already numerous successful examples and rapid technological improvements promise expansion of PV's present niche market to that of a major energy provider of the 21st century. This handbook is the outcome of a five year programme which took place under the auspices of the International Energy Agency. Architects and solar experts from 13 countries addressed the wide range of engineering and architectural issues involved in the successful integration of PV into buildings. It demonstrates how to maximise the overall solar contribution to the building; integrate PV effectively with the building structure; clarify the relationship of PV with other elements of the building's energy system; optimise the system economics. It forms a thorough design guide that covers all aspects if the subject and will enable all building designers, engineers and property owners to make the integration of PV into buildings an architecturally appealing and energetically effective option.

This text discusses factors such as mast overload, capacity of drawworks, and deviation in the hole to be drilled and the strata to be drilled. An omnibus approach to drilling techniques and problems is adopted.

Deals with the design and execution of grouting works in all kinds of rock and soil, including jet grouting. Design principles are discussed whereby different approaches, exercised in different parts of the world, are compared to each other and evaluated.

Invited international contributions to this exciting new research field are included in this volume. It contains the specially selected papers from 45 key specialists given at the Symposium held under the auspices of the prestigious International Union of Theoretical and Applied Mechanics at Turin in October 1994.

Tunnelling is a high risk business. Success depends crucially on the nature of the ground through which the tunnel is being driven. The cost of a thorough site investigation is usually only a small fraction of the cost of the construction work but this crucial phase of a project is often given too low a priority. This text provides a review of tunnelling contracts, particularly those for sewerage and drainage tunnels. It reviews site investigation methods, contract preparation and tender evaluation, tunnel costruction, claims and records, and the post-construction phase. Examples of good and bad practice of site investigation and other aspects of tunnelling are given, and the text is supported by over 500 references. Supplementary information in the second part of the book expands on particular aspects such as ground vibration and noise. Among other topics covered are quality assurance, rock properties and testing, pollution, permeability and dewatering.

In the late 1990s there has been a dramatic increase in the number of mathematical models developed to tackle geomechanics problems, largely as a result of the increasing availability and power of computers and the parallel evolution of versatile numerical techniques. This text examines the experimental and theoretical aspects of the pre-failure and post-failure behaviour of geomaterials within the frame of bifurcation theory. Coverage includes basic continuum mechanics for dry and fluid infiltrated porous media, bifurcation and stability analyses applied to layered geological media and granular materials, and theories for generalized continua (Cosserat and gradient theories) as applied to materials with microstructure and in relation to strain localization phenomena. This volume will be a source of reference for researchers and practitioners in soil and rock mechanics, and foundation engineering, and engineers, geologists and structural, civil and geotechincal engineers.

A state-of-the-art report prepared by RILEM Technical Committee 116-PCD. At present, durability of concrete is controlled by specifying the materials to be used, the methods of mixing, placing, curing and so on. This approach is often unsatisfactory and it is a common objective of concrete researchers and engineers to develop performance criteria which allow the potential durability of a particular concrete mix or structure to be estimated. However, the complexity of concrete as a material and the difficulty of developing consistent and reliable test methods has meant that progress has been slow. International interest in the subject is growing strongly with the development of international standards and so this book is very timely in giving an authoritative, international review of the subject. It will set the scene for the next few years as a key source of information and advice.

This book addresses problems in structural dynamics and control encountered in such applications as: aerospace structures, robotics, earthquake-damage prevention, and active noise suppression. The rapid developments of new technologies and computer power have made it possible to formulate and solve engineering problems that seemed unapproachable only a few years ago. The treatment combines concepts from control engineering (such as system norms and controllability) and structural engineering (such as modal properties and modal models), thereby both revealing new structural properties as well as giving new insights into well-known laws. The techniques discussed will make it easier for structural engineers to design control systems and for control engineers to deal with structural dynamics. The discussion begins by defining flexible structures and structural models, using such examples as the international space station and the antennas of NASA's deep-space network. The book then turns to controllability and observability; properties of system norms (Häsubinfinityü, Häsub2ü, and Hankel); and model reduction in terms of these norms. A discussion of sensor and actuator location follows: selecting these is rarely an easy task. The concluding chapters discuss the design of dissipative LQG and Häsubinfinityü controllers. Matlab codes for many of the procedures and methods discussed in the book are included.

At some point, most home-owners have to make a choice: whether to move or extend their property. In the case of the latter, there is a further choice - to put the whole matter into other hands or to try to understand the processes involved so that the whole business is carried out efficiently and cost-effectively. Those working or planning to work in the construction industry also need to be reminded of the pitfalls of local authority requirements, building control and planning, and this text provides an account of the necessary action.

Post-tensioning is the most versatile form of pre stressing, a technique which enables engineers to make the most effective use of the material properties of concrete, and so to design structural elements which are strong, slender and efficient. Design in post-tensioned concrete is not difficult and, if done properly, can contribute significantly to the economy and the aesthetic qualities of a building. Post-tensioned floors have found widespread use in office buildings and car park structures, and are also frequently employed in warehouses and public buildings. However, in spite of this, most prestressed concrete texts devote comparatively little attention to floors, concentrating instead on beam elements. This book answers the need for a comprehensive treatment of post-tensioned floor design.

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."

It draws together research and new applications in continuum, damage and fracture mechanics approaches.

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.

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

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.

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.
