It is an essential reference to the most promising innovative rock engineering. Chapters are carefully developed to cover (1) new fractal algorithms (2) five engineering cases. This authored book addresses the issue with a holistic and systematic approach that utilizes fractal theory to nonlinear behavior in rock engineering. The book is written for researchers interested in rock and geological engineering as well as organizations engaged in underground energy practices.

This book presents the general concept of the Virtual Distortion Method with the necessary theoretical background and a number of its applications to problems of structural analysis and design. The approach presented allows for the development of efficient computational methods for the numerical analysis of problems where, e.g., local failures, the temperature field or permanent plastic deformations are described by virtual distortions. On the other hand, properly modelled (fictitious) virtual distortions can be used to simulate structural modifications such as material redistribution applicable in the optimal redesign process. Finally, virtual distortions can be used to mimic the behaviour of actuators in active structural control problems: shape, stress or vibration control. A number of numerical algorithms are developed, enabling one to solve various problems of structural analysis, design and control.

Based upon the author's wide experience in a broad range of projects, this invaluable book sets the scene and places rock installation in the context of the offshore industry today. This is an industry where health, safety and environmental considerations are factored in to a project with the same level of professionalism as regulatory compliance and good design. Full information is provided about planning, preparation, execution and reporting of a rock installation project. Brief but key information is provided about rock types, the nature of the seabed and the relationship between the quarry and the receiving vessel, which together form a system of turning a terrestrial geological formation into a rock berm offshore. Rock installation vessels, their characteristics, equipment and capabilities are examined in outline. This book is based upon personal experience offshore in a series of rock installation projects over the last 16 years. It covers the oil and gas sector, coastal engineering, power and telecom cable projects and draws on practice in the UK, Norwegian and Danish Exclusive Economic Zones where much rock installation takes place. The range in scale is significant, from large oil field development projects to those of a much more specialised nature such as the preparation of sites from which a jackup rig can safely operate. The marine environment is examined in some detail. The author believes that all personnel working in the offshore industry, whether at sea or in onshore positions, need to understand the harsh but majestic, hostile and often unforgiving marine environment. With a number of new operators developing both end of life and new fields, knowledge concerning SRI has been diluted or even lost. This book is a useful enabler for project staff and new client representatives offshore to have a productive rock installation experience from the initial discussions with a contractor to the final results and verification.

A major new reference book bringing together wide-ranging expert guidance on coastal engineering, including harbours and estuaries. It covers both traditional engineering topics and the fast developing areas of mathematical modelling and computer simulation.

Ground motion due to earthquake excitation often induces disastrous disturbances that severely damage structures and their contents. Conventional earthquake-resistant design focuses on the strengthening of structures to avoid collapse, while little attention is paid to the prevention of damage as it is almost impossible to construct completely "earthquake proof" structures at reasonable cost. This state-of-the-art volume explores seismic isolation as an alternative and performance-based design approach to minimise earthquake induced loads and resulting damage in low to medium-rise buildings. A discussion of the characteristics, advantages and limitations of seismic isolation is followed by a demonstration of its capability to decouple a structure from the damaging effects of ground acceleration. Describes currently used seismic isolation systems in detail. Evaluates the performance of seismically isolated structures and provides examples of their response under earthquake action. Proposes a preliminary design methodology for seismically isolated structures. Accessible to both students and practising structural engineers who need to familiarise themselves with this approach.

Soil represents the oldest and most used building material. Current paradox is that up to now this subject of Earth structures was not fully covered. This book describes the principles of soil workability as construction material including two basic forms of its treatment using geosynthetics and stabilization. It describes logics of design and control of Earth structures that significantly differ from other building materials, which brings more uncertainty and risk. Therefore Earth structures are still offering wider space for detailing the design and improvement of financial calculations quality.

Following the general part, where the principles of limit states according to Eurocode 7 - Geotechnical design are also described in more detail, the book concentrates on earth structures of transport, water and environmental projects. The parts devoted to transport projects covers in more details limit states of stability and deformation. The part devoted to water engineering prioritizes the limit state of internal erosion. The part regarding earth structures of environmental structures describes new phenomenon where part of the structure is created from non standard materials, usually susceptible to internal collapse, double porosity, unsaturation, etc. It also concentrates on protection of the surrounding from contamination.

The book focuses on the principles, logic of processes, understanding of the most important problems, so that all participants of the construction (client, designer, contractor and supervisor) are able to build these earth structures more safely and economically.

Innovative Shear Design presents a new, rational and economical design procedure that offers increased protection against shear for all types of structures. The first part of the book describes the internal forces imposed on any flexurally bent member, and goes on to describe how these can interact with external loading forces to cause failure. The author then details the new design approach, and explains how its implementation can prevent cracking and failure for a given load. The book contains numerous practical examples describing optimum design techniques for all types of structure. Innovative Shear Design is an essential reference for structural designers, architects, academics, and researchers. It will also be a key reference text for students of structural design.

The material properties, spatial configuration and variation in the construction of steel structures means they often have the potential for reconstruction. This book provides civil engineers with the necessary information to approach projects of reconstruction and reinforcement of steel structures such as buildings, masts, towers, chimneys, storage tanks and bridges. The book analyses the causes of failures, presents up-to-date information on the methodology and equipment used for diagnosis of failures, and includes a survey of repair and reconstruction techniques. The methods described are illustrated by examples of successful real-life case studies, and relevant codes are examined where appropriate. Assessment and Refurbishment of Steel Structures is a comprehensive combination of both theory and practice, and is an essential reference for engineers engaged in the modernisation and repair of civil engineering steel structures.

Forty scientists working in 13 different countries detail in this work the most recent advances in seismic design and performance assessment of reinforced concrete buildings. It is a valuable contribution in the mitigation of natural disasters.

THis new edition of this successful book has been thoroughly revised to take account of recent advances in our understanding of slope stability and instability. The book begins with a consideration of slope stability processes, including the evolution of natural slopes. Thebehaviour of soil and rocks, and the flow of water through them, (which is of fundamental importance to their shear strength), are explained in considerable detail. The principles and techniques of stability analysis are covered in two separate chapters. From this basic theory the author develops practical design criteria for new slopes, discusses remedial measures for slope stabilization, and provides guidance on investigation of landslides. Computer programs to facilitate analysis and design are discussed where appropriate, and the book concludes with several carefully selected case histories, and design recommendations for man-made slopes.

Serviceability failures of concrete structures involving excessive cracking or deflection are relatively common, even in structures that comply with code requirements. This is often as a result of a failure to adequately account for the time-dependent deformations of concrete in the design of the structure. The serviceability provisions embodied in codes of practice are relatively crude and, in some situations, unreliable and do not adequately model the in-service behaviour of structures. In particular, they fail to adequately account for the effects of creep and shrinkage of the concrete. Design for serviceability is complicated by the non-linear and inelastic behaviour of concrete at service loads. Providing detailed information, this book helps engineers to rationally predict the time-varying deformation of concrete structures under typical in-service conditions. It gives analytical methods to help anticipate time-dependent cracking, the gradual change in tension stiffening with time, creep induced deformations and the load independent strains caused by shrinkage and temperature changes. The calculation procedures are illustrated with many worked examples. A vital guide for practising engineers and advanced students of structural engineering on the design of concrete structures for serviceability and provides a penetrating insight into the time-dependent behaviour of reinforced and prestressed concrete structures.

Motion structures are simply assemblies of resistant bodies connected by movable joints. Unlike conventional structures, they allow large shape transformations to satisfy practical requirements and they can be used in: shelters, emergency structures and exhibition stands aircraft morphing wings satellite solar panels and space antennas morphing core materials for composites medical implants for minimum invasive surgery. Though traditionally the subject falls within structural engineering, motion structures are more closely related to other mechanisms, and they draw on the principles of kinematic and geometrical analysis in their design. Indeed their design and analysis can be viewed as an extension of the theory of mechanisms, such as rigid origami, and can make effective use of a wealth of mathematical principles. This book outlines the relevant underlying theory of motion structural concepts, and uses a number of innovative but simple structures as examples.

Increases in computer power have now enabled engineers to combine materials science with structural mechanics in the design and the assessment of concrete structures. The techniques developed have become especially useful for the performance assessment of such structures under coupled mechanistic and environmental actions. This allows effective management of infrastructure over a much longer life cycle, thus satisfying the requirements for durability and sustainability. This ground-breaking new book draws on the fields of materials and structural mechanics in an integrated way to address the questions of management and maintenance. It proposes a realistic way of simulating both constituent materials and structural responses under external loading and under ambient conditions. Where the research literature discusses component or element technology related to performance assessment, this book uniquely covers the subject at the level of the whole system including soil foundation, showing engineers how to model changes in concrete structures over time and how to use this for decision making in infrastructure maintenance and asset management.

An Insiders' Guide to Inspecting, Maintaining, and Operating Bridges Suspension bridges are graceful, aesthetic, and iconic structures. Due to their attractiveness and visibility, they are well-known symbols of major cities and countries in the world. They are also essential form of transportation infrastructure built across large bodies of water. Despite being expensive to build, they are economical structures for the lengths they span. They have evolved significantly from the basic concept dating back to 200 BC China through the first design for a bridge resembling a modern suspension bridge, attributed to Fausto Veranzio in 1595, to present day span lengths close to two kilometers. Offers Insight from Bridge Owners across the Globe Many of these bridges carry significant traffic, and their upkeep is very important to maintain transportation mobility. They offer grace and functionality, yet are extremely complex to construct and maintain. Bridge owners spend considerable amount of time and resources to ensure uninterrupted service, safety, and security for users. Inspection, evaluation, maintenance, and rehabilitation have evolved significantly. Modern materials and innovative design and construction practices have been integrated into these bridges to maintain durability and extended service life. Inspection, Evaluation and Maintenance of Suspension Bridges Case Studies gives detailed case studies of the Manhattan, Akashi Kaikyo, Tsing Ma, Storebaelt East, Forth Road, Bronx-Whitestone, George Washington, Angus L. Macdonald, Mid-Hudson, Shantou Bay, and Kingston-Port Ewen Bridges. It is written by the owners and practitioners who strive to cost-effectively manage them, and applies all the inspection, evaluation, and rehabilitation methods discussed in the companion volume to give a comprehensive picture of how suspension bridges are mana

An Engineering Companion to Mechanics of Materials is the first volume in the Momentum Press collection The Modern Engineering Companions: A Systems Approach to the Study of Engineering. In Mechanics of Materials, we apply the intuitive "systems approach" to learning, the advantages of which are several. The student first gets a broad overview of the entire subject rather than the narrow piecemeal vision afforded by the traditional "component approach" common to most engineering texts. Mechanics of Materials comes with additional features to improve student learning, including Common Confusing Concepts (C3) noted and clarii ed, indication of key concepts, side bar discussions, worked examples, and exercises for developing engineering intuition. The Companions are intended as a supplementary resource to help both undergraduate, graduate, and post-graduate students better learn and understand engineering concepts.

This text presents the most effective analysis for predicting the true stresses and deflections of concrete structures, accounting for creep and shrinkage of concrete and relaxation of prestressed reinforcement. Sustainability has become a major requirement in modern structures, which need to sustain satisfactory service over a longer life. It is not rare to specify a life span of 100 years for infrastructure such as bridges. This complete and wide-ranging study of stresses and deformations of reinforced and prestressed concrete structures focuses on design methods for avoiding the deflections and cracking that diminish serviceability. This fourth edition has a new emphasis on designing for serviceability. It has been comprehensively updated. It now includes 65 solved examples and more than 45 instructive problems with answers given at the end of the book. An accompanying website contains design calculation programs, which allow interactive data input. Independent of codes of practice, the book is universally applicable, and is especially suitable for practising engineers and graduate students.

Because of their complexity and scale, metro structures capture all the essential aspects of a cut-and-cover structure, and so are given primary focus in this book. The design of a metro construction is outlined coherently and in detail; and the reader is shown how to apply this design process equally well to other, relatively simple, cut-and-cover structures. Geotechnical and structural engineering principles are combined with both design and construction practice to make this book a unique guide for engineers. See www.cutandcoverstructures.com/ for further information.
