The concept of effective stress and the effective stress equation is fundamental for establishing the theory of strength and the relationship of stress and strain in soil mechanics and poromechanics. However, up till now, the physical meaning of effective stress has not been explained clearly, and the theoretical basis of the effective stress equation has not been proposed. Researchers have not yet reached a common understanding of the feasibility of the concept of effective stress and effective stress equation for unsaturated soils. Effective Stress and Equilibrium Equation for Soil Mechanics discusses the definition of the soil skeleton at first and clarifies that the soil skeleton should include a fraction of pore water. When a free body of soil skeleton is taken to conduct internal force analysis, the stress on the surface of the free body has two parts: one is induced by pore fluid pressure that only includes normal stress; the other is produced by all the other external forces excluding pore fluid pressure. If the effective stress is defined as the soil skeleton stress due to all the external forces excluding pore fluid pressure, the effective stress equation can be easily obtained by the internal force equilibrium analysis. This equation reflects the relationship between the effective stress, total stress and pore fluid pressure, which does not change with the soil property. The effective stress equation of saturated soils and unsaturated soils is unified, i.e., o~=o~t -Seuw-(1-Se)ua. For multiphase porous medium, o~=o~t -u*,u*=Seiui(i=1,2,...,M). In this book, a theoretical formula of the coefficient of permeability for unsaturated soils is derived. The formula of the seepage force is modified based on the equilibrium differential equation of the pore water. The relationship between the effective stress and the shear strength and deformation of unsaturated soils is preliminarily verified. Finally, some possibly controversial problems are discussed to provide a better understanding of the role of the equilibrium equation and the concept of effective stress.

Landslides and slope failure are common in the US and rest of the world. The landslides cause significant damage to infrastructure and millions of dollars are required each year to fix the slope. A sustainable and costeffective option to stabilise the slope can have significant benefits, as it will reduce the cost of maintenance and when using recycled pins, it may help the environment at the same time. The recycled plastic pin is made from recycled plastic bottles and other plastic waste. Several demonstration projects already proved the effectiveness of RPP as an alternative option to fix slope failure, with a maximum failure depth of 7-8 ft. In this book, every detail of the slope stabilisation technique using recycled plastic pins, including the design techniques and several case studies, are included. This will help to explain the basics of this important technique and will be used as reference to design the slope stabilisation scheme using recycled plastic pins.

This book describes the enormous depth of work carried out since the early 1970s on the Messina Strait Bridge, up to the recent award of the detailed design and construction contract. This important work has included extensive studies, concepts and design developments, with far reaching applications, which have all confirmed the feasibility of this huge endeavour and have led to the optimisation of costs and expected performance levels. Attention is focused not only on the design itself, but also on the context for the project (e.g. historical, geological, seismo-tectonic and wind conditions; structural and mechanical properties; project management and financial aspects; and environmental considerations), and on the great challenges involved. Thus, considering the innovations and specific solutions adopted in overcoming the challenges presented by constructing a world record span of 3,300 metres at this site, it becomes clear how the Messina Strait Crossing will take its place as a masterpiece in bridge engineering history. This book will be of interest to bridge and structural engineers, geotechnical and wind engineers, mechanical and earthquake engineers, graduate students in all these areas and all others with a broad interest in bridge design and engineering.

With increasingly sophisticated structures involved in modern engineering, knowledge of the complex vibration behavior of plates, shells, curved membranes, rings, and other complex structures is essential for today's engineering students, since the behavior is fundamentally different than that of simple structures such as rods and beams. Now in its third edition, Vibrations of Shells and Plates continues to lay an analytical and computational foundation for the study of vibration in these structures. Vibrations of Shells and Plates, Third Edition is updated with substantial new material reflecting advances made over the past decade since publication of the second edition. The author demonstrates how the vibration behavior of shells and plates differs from that of beams through theoretical development and examples. He also explains complicating effects on vibration such as the influence of rotation, shear, rotatory inertia, moment loading, residual stresses, and composite layers. New material includes the parabolic cylindrical shell, natural frequencies and modes, power series method, and explicit strain energy equations for many standard cases. Intended for graduate and post-graduate study in vibration, acoustics, noise control, and stress analysis, this textbook provides a strong foundation in vibration theory, offers analytical solutions that illustrate actual behavior of structures, and prepares students to perform finite element and finite difference analysis.

Following his succesful How to Pass the APC: Essential Advice for General Practice Surveyors, Austen Imber's latest publication examines surveyors' work in practice. The case work is based mainly on examples of APC candidates' critical analysis, and is supported by additional guidance on the key issues arising in practice. In a clear, practical way the book covers the public, private and corporate sectors and enables graduates to understand the roles of the various participants in the property industry. Subjects covered include investment valuation, development valuation/appraisal, profits valuation, the Red Book, lettings, sales, rent reviews, lease renewals, estate management, ratings, planning, development, regeneration, compulsory purchase, telecoms and insolvency. The hands-on style of the candidates' critical analysis, clearly shows the detailed reasoning behind the initial strategies and decisions throughout a case. The examples of APC interview questions and tasks for study are invaluable in encouraging graduates to consider further issues - including the many practical problems which graduates need to understand in order to succeed in practice and with their APC interview. Professional ethics are also represented within the cases featured. The APC Casebook is an essential tool in preparing for the final assessment stage of the APC, as well as being an important reference source for candidates throughout their APC training.

The interaction between engineering and the law is undergoing dramatic changes. Product liability, laws have been introduced in Japan, patent claims over living organisms have been made in bioengineering and the differing national laws of copyright protection and liability are in the process of harmonisation, especially in the European Union. The pace and complexity of these changes make it essential for technologists, lawyers, engineers and insurance experts to establish a common basis for understanding, co-operation and exchange of expertise. The recently founded International Society for Technology, Law and Insurance aims to foster such co-operation. This volume features 46 selected contributions which address various topical issues and the law. The most important issues relate to engineering risks, quality assurance and assessment and legal implications assiciated with them. Recent failure cases are explained and the technical, legal and insurance-related issues discussed in detail.

The Audience in Everyday Life argues that a media audience cannot be studied in front of the television alone - their interaction with media does not simply end when the set is turned off. Instead, we must study the daily lives of audiences to find the undercurrents of media influence in everyday life. Applying new developments in cultural anthropology and folklore to media studies, S.Elizabeth Bird offers a series of empirically based audience studies of phenomena that include media scandals, fan culture, representations of race and ethnicity, tabloid journalism, and runaway media hoaxes. Bird provides a range of useful tools and methods for scholars and students interested in the ways media is consumed in everyday life.

The use of modern composite materials in construction offers the structural engineer and designer exciting opportunities for all types of buildings and structures. By far the most commonly used and longest established composite material is the combined use of steel and concrete in the form known in most parts of the world as 'composite construction'.
Composite Construction takes a comprehensive look at recent developments in this fast growing area. With each chapter written by an acknowledged expert in the field, this book aims to link physical behaviour, engineering approximation, appropriately applied theoretical concepts and design approaches.
Composite Construction is not simply a code commentary, nor does it deal with topics purely in terms of developing theory from first principles. Rather, the emphasis is strongly placed on providing both the practising engineer and the student with an understanding of physical behaviour, and the intelligent application of this knowledge in practice

Although primarily designed as a supplement to Soil Mechanics: Basic Concepts and Engineering Applications, this book can be used as anindependent problem solving text, since there is no specific reference to any equation or figure in the main book and contains problems and fully-worked solutions. Written for university students taking first-degree courses in civil engineering, environmental and agricultural engineering, its main aim is to simulate problem solving learning as well as facilitating self-teaching. The special structure of the book makes it possible to be used in two, three and four year undergraduate courses in soil mechanics. As it includes new and advanced topics tis work book will also be a valuable resource for the practising professional engineer. Although readers are assumed to have prior knowledge in soil mechanics; necessary basic information is included in each worked example.

The premixing method involves adding a small amount of cement to the soil used in reclamation. The cement reacts with the water in the soil to produce a stronger, non-liquifying material for construction. The premixing method can therefore reduce construction time, as the counter-measure work is carried out simultaneously with the reclamation process. In addition, the resultant material has enhanced bearing capacity, and there is a reduction in earth pressure due to the increase in cohesion. This book examines the premixing method in detail and is essential reading for coastal engineers, hydrologists, or construction engineers working in soft soil areas.
