Internationally, the mechanized excavation of tunnels has intensified in the last two decades, as the number of tunnels being constructed for subways and railway underpasses increases. The subject of mechanized tunnelling in urban areas has not previously received the attention that it deserves, despite there being specific hazards associated with the construction of tunnels in metropolitan areas, including poor ground conditions, water tables higher than the level of tunnels, and subsidence leading to damage to the existing structures on the surface. The application of technologies for achieving the stability of the tunnel and for minimizing surface settlement is described in this book. Accurate characterization of the ground; rigorous assessment and management of risk from design to maintenance; the correct choice of a tunnel boring machine and a plan for the advancement of the tunnel; specific excavation procedures and real-time monitoring of excavation parameters are all discussed in this thorough work.

This classic and essential work has been thoroughly revised and updated in line with the requirements of new codes and standards which have been introduced in recent years, including the new Eurocode as well as up-to-date British Standards.

It provides: a general introduction; details of analysis and design of a wide range of structures and examination of design according to British and then European Codes.

Civil Engineering has recently seen enormous progress in the core field of the construction of deep foundations. This book is the result of the International Workshop on Recent Advances in Deep Foundations (IWDPF07), which was held in Yokosuka, Japan from the 1st to the 2nd of February, 2007. Topics under discussion in this book include recent research achievements and case histories; and current advances in the applied aspects of deep foundations, such as reliability-based design, field tests and experimental field work. The book also features the latest numerical simulation methods and theoretical findings. There are nine keynote lectures, focusing on foundation engineering in different parts of the world, and thirty-three state-of-the-art papers from eminent international experts. The techniques covered include sheet piles, piles, pile-ground improvement and ground improvement, while dynamic aspects and design are also discussed.. This book is intended for an international audience of researchers and professionals in soil and foundation engineering.

A new analytical method that uses the capacity axis of a section to determine its minimum capacity for biaxial bending as well as provide the reference for equilibrium of external and internal forces has been developed. Introducing this method, Structural Analysis: The Analytical Method illustrates the procedures for predicting the capacities of circular and rectangular sections in concrete and steel materials. By applying basic mathematics to the standard principles in structural analysis, the author derived for the first time all the equations required for solving the true capacity of circular and rectangular sections in structural design. Previous authors have been unable to employ basic mathematics and thus resorted to approximate methods, such as the standard interaction formula for biaxial bending or more sophisticated methods illustrated in current literature on the subject of determining the capacity of above structural sections. The book begins with a discussion of the capacities of rectangular and circular footing foundation for a given allowable soil-bearing pressure followed by the author's latest integration of the Boussinesq's elastic equation for the dispersion of surface loads in determining the exact average pressure to use in the standard soil settlement formula. The author provides all the equations and tabulated values of key point's capacities of commercially-produced steel pipe, rectangular tubing, and steel I-sections. He then lists the derived equations for the determination of the ultimate strength capacity curve of reinforced concrete columns and concrete-filled tubular columns without using the rectangular stress block method of analysis. Elucidating an elegant, straightforward, and precise method, thus limiting guesswork, this book makes it easier to confirm the adequacy and safety of designs by direct comparison of the external loads to the internal capacities of circular and rectangular sections in structural analysis and design.

The construction materials industry is a major user of the world's resources.

The three volumes of Fracture Mechanics of Concrete and Concrete Structures comprise the Proceedings of the 6th International Conference on Fracture Mechanics of Concrete and Concrete Structures, Catania, Italy, 17-22 June 2007. Volume 1, New Trends in Fracture Mechanics of Concrete, is divided into four parts: (1) Theoretical and Numerical Methods in Fracture Mechanics of Concrete; (2) Experimental Methods in Fracture Mechanics of Concrete; (3) Constitutive Damage Modelling of Concrete; (4) Time Effects in the Damage and Fracture of Concrete. Over the last twenty years, many theoretical, numerical and experimental methods have evolved in the field of Fracture Mechanics of Concrete. These have led to practical applications in reinforced-concrete design, assessment, monitoring and retrofitting, as well as innovative high-performance and durable cementitious materials. Although Fracture Mechanics of Concrete is now mature as a framework for defining and solving a variety of engineering problems, there is still much work to be done in improving previous theoretical and numerical models, and for re-interpreting established phenomena. In particular, there are new developments in the treatment of scale effects; the implementation of 3D-discretisation; and the combination of continuous and discontinuous models. Other areas of rapid progress are the development of innovative testing techniques; the proposal of non-local and anisotropic constitutive laws; the formulation of lattice and multiscale models, and the development of coupled multifield theories. Volume 2, Design, Assessment and Retrofitting of RC Structures, also has four parts: (1) Theoretical and Experimental Investigation on the Mechanical Behaviour of RC Structures; (2) Practical Problems in RC Structural Applications; (3) Monitoring and Assessment of RC Structures ; (4) Maintenance and Retrofitting of RC Structures. Fracture Mechanics is used to interpret different problems: anchor fastening; plastic rotation capacity in RC beams; and minimum reinforcement and ductility. It is also relevant to questions of size effect; flexural-shear-crushing failure mode transition; cohesive crack modelling; and rebar corrosion. Traditional problems arising in RC structures are also reconsidered and reinterpreted: crack width evaluation; dynamic and impact loading; fire and thermal degradation; fatigue strength assessment; as well as punching and spalling. Monitoring and assessment issues in RC structures come under discussion, such as acoustic emission and ultra sound. Maintenance and retrofitting techniques are treated, including the increasing popular technique of fibre-reinforced polymer sheets used as wrapping around cracked structures, for example, to strengthen beams and columns. Volume 3, High-Performance Concrete, Brick-Masonry and Environmental Aspects, is divided into four parts: (1) High-Performance Concrete; (2) Fiber Reinforced Concrete; (3) Brick-Masonry and other Quasi-Brittle Materials; and (4) Environmental Issues. Concrete technology has developed at a fast pace during the last two decades and material performance has been significantly improved. High-performance concrete (HPC) is now a reality. Initially, attention focused on compressive strength and the enhanced concrete was named "high-strength concrete" (HSC). Later, however, other issues arose, such as workability and durability. There was an increasing demand for enhanced rheology (in terms of flowability and cohesion, i.e. no segregation effects) in the fresh state, and compactness in the hardened state. Researchers responded with the development of self-consolidating concrete (SCC). Since higher strength generally implies higher brittleness, fibre-reinforced concrete (FRC) has generated considerable interest for its enhanced toughness under both static and dynamic loading, as well as for its ability to control concrete cracking. Nowadays, there are many types of fibre on the market, with different material and geometric qualities. The remarkable toughness of FRC, due to its fracture energy, combined with advances of nonlinear fracture-mechanics in modelling the structural behaviour, means that the advantages of incorporating fibres can be fully exploited. Furthermore, by adopting optimized mix-designs (in terms of fibre content and type, and of pozzolanic or hydraulically-active adjuncts) the increasingly important requirements of durability can be met, even under the most severe environmental conditions (like chemical aggression, high and low temperatures, and fatigue). Recently, the field fracture mechanics has extended to other brittle or quasi-brittle materials, such as brick-masonry, glass, polymers and ice, and a more realistic evaluation of the safety level of structures has been obtained. These proceedings present a wealth of information, and will be useful to professional civil engineers, postgraduate students and researchers.

A detailed view on the effects of seismic activity on tank structures As the use of aboveground and underground storage tanks (ASTs and USTs) continues to grow--with approximately 545 thousand in the US alone--the greatest threat to from AST and USTs is the contamination of groundwater, a vital source of drinking water throughout the world and one that close to half of Americans rely upon. These tanks suffer a great deal of strain during an earthquake, as a complicated pattern of stress affects them such that poorly designed tanks have leaked, buckled, or even collapsed during seismic events. Furthermore in oil and gas industrial plants, the risk of damage is even more critical due to the effect of explosion, collapse, and air or soil contamination by chemical fluid spillages. Seismic Design and Analysis of Tanks provides the first in-depth discussion of the principles and applications of shell structure design and earthquake engineering analyses focused on tank structures, and how these methodologies can help prevent the destruction of AST and USTs during earthquakes. Providing a thorough examination into the design, analysis, and performance of steel, reinforced concrete, and precast tanks, this book takes a look at tanks that are aboveground, underground, or elevated, anchored and unanchored, rigid or flexible, and evaluates the efficacy of each method during times of turbulence--and it does so without getting bogged down with impenetrable math and theory. Seismic Design and Analysis of Tanks readers will also find: Global approach for the best analytical and practical solutions available in each region: Discussion of the latest US codes and standards from the American Society of Civil Engineers (ACSE 7), American Concrete Institute (ACI 350,3, 371.R), American Water Works Association (AWWA D100, D110, D115), and the American Petroleum Institute (API 650) An overview of European codes and standards including Eurocode 8-4 and CEN-EN 14015 Hundreds of step-by-step equations accompanied by illustrations Photographs that feature real-world damage to tanks caused by seismic events Perfect for practicing structural engineers, geotechnical engineers, civil engineers, and engineers of all kinds who are responsible for the design, analysis, and performance of tanks and foundations--as well as students studying engineering--Seismic Design and Analysis of Tanks is a landmark text, the first work of its kind to deal with seismic engineering performance of storage tanks.

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.

Ordinary concrete is strong in compression but weak in tension. Even reinforced concrete, where steel bars are used to take up the tension that the concrete cannot resist, is prone to cracking and corrosion under low loads. Prestressed concrete is highly resistant to stress, and is used as a building material for bridges, tanks, shell roofs, floors, buildings, containment vessels for nuclear power plants and offshore oil platforms. With a wide range of benefits such as crack control, low rates of corrosion, thinner slabs, fewer joints and increased span length; prestressed concrete is a stronger, safer, more economical and more sustainable building material. The introduction of the Eurocodes has necessitated a new approach to the design of prestressed concrete structures and this book provides a comprehensive practical guide for professionals through each stage of the design process. Each chapter focuses on a specific aspect of design * Fully consistent with Eurocode 2, and the associated parts of Eurocodes 1 and 8 * Examples of challenges often encountered in professional practice worked through in full * Detailed coverage of post-tensioned structures * Extensive coverage of design of flat slabs using the finite element method * Examples of pre-tensioned and post-tensioned bridge design * An introduction to earthquake resistant design using EC 8 Examining the design of whole structures as well as the design of sections through many fully worked numerical examples which allow the reader to follow each step of the design calculations, this book will be of great interest to practising engineers who need to become more familiar with the use of the Eurocodes for the design of prestressed concrete structures. It will also be of value to university students with an interest in the practical design of whole structures.

The use of tiebacks has evolved from simple lateral support during construction or excavation, to an increased number of permanent installations. This book examines the process of choosing the right tie-back or anchor for the job and the varying factors that influence those decisions from concept to construction, including corrosion, long-term capacity and soil conditions.

Topics covered in this title include: the fracturing and damage of composite materials; ceramics; metals; and concretes and rocks at different scales in both monotonic and cyclic loading.

This volume covers the second great period of developments in iron construction from 1850, following its establishment as a structural material described in Volume 9 of this series. Using the Crystal Palace of 1851 as a starting-point, the papers trace the history of iron-frame construction in Britain, France and America, and show its importance in fireproof construction, and in lattice truss and arch bridge design. A final group of papers illustrates the emergence of steel in framed buildings in both Britain and America. The selection brings out the important and daring contribution of individual engineers in their use of this material.

Today's construction environment is more complex than any previous era. The possible impediments to a project's successful completion include not only "bricks and mortar" issues like material availability or curtain wall testing, but a broad array of concerns involving the economic, political, social, environmental, archeological, community, and historic preservation aspects of the project. Costly delays are common; regulatory processes can be prohibitive; stakeholders have more say. All of the people involved in an urban construction project must be knowledgeable about, and conversant with these conditions.

Bringing together over 500 years of combined professional experience, Construction in Cities: Social, Environmental, Political, and Economic Concerns provides you with a compendium of knowledge with which to solve problems and propel your projects. Beginning with an overview of the regulations governing construction in cities, the book continues with concrete, practical advice for below-ground work such as tunnels, roadways and foundations. It follows with an examination of five actual projects to explore ways to complete elaborate urban buildings. Finally, the book takes you deep into the murky waters of issues that often halt construction projects.

Since the unexpected always happens in construction, you need a book on your shelf to reach for when it does - a source that delineates clean and concise recipes for successfully dealing with such diverse conditions as unexpected archeological finds, dying trees, and toxic air. If you play a role in ensuring the delivery of capital projects in an urban environment, Construction in Cities serves as a handy reference of actions and methods for overriding these barriers.

This book proposes the concept of a multi-layer pavement system to fulfill the blast resistance requirement for pavement design. It also presents a damage pattern chart for multi-layer pavement design and rapid repair after blast load. Such a multi-layer system consists of three layers including asphalt concrete (AC) reinforced with Geogrid (GST) at the top, a high-strength concrete (HSC) layer in the middle, and engineered cementitious composites (ECC) at the bottom. A series of large-scale laboratory impact tests were carried out to prove the usefulness of this concept and show its advantages over other conventional pavement system. Furthermore, field blast tests were conducted to show the actual behavior of this multi-layer pavement system subjected to blast load under real-world conditions.

The importance of design has often been neglected in studies considering the history of structural and civil engineering. Yet design is a key aspect of all building and engineering work. This volume brings together a range of articles which focus on the role of design in engineering. It opens by considering the principles of design, then deals with the application of these to particular subjects including bridges, canals, dams and buildings (from Gothic cathedrals to Victorian mills) constructed using masonry, timber, cast and wrought iron.

Woodworking has been one of the most important technologies from the earliest times. Carpentry was important for buildings and bridges and as an integral part of most construction processes. The history of this subject has been explored by a variety of scholars, from archaeologists who have studied medieval timber techniques to engineers who have been interested in the development of bridges. The different studies have explored the methods of carpentry, the behaviour of the structures that were built and even the economic and social histories behind the development of carpentry techniques. This book collects together a number of papers representing this full range of scholarship as well as providing a general review of work in the field.

There are various techniques to optimize either structural parameters, or structural controllers, but there are not many techniques that can simultaneously optimize the structural parameters and controller. The advantage of integrating the structural and controller optimization problems is that structure and controller interaction is taken into account in the design process and a more efficient overall design (lower control force/lighter weight) can be achieved, and also multidisciplinary design optimization can be performed. The down side is that the combined optimization problem is more difficult to formulate and solve, and computations are increased. This volume is a comprehensive treatment of dynamic analysis and control techniques in structural dynamic systems and the wide variety of issues and techniques that fall within this broad area, including the interactions between structural control systems and structural system parameters.

Many traditional masonry buildings are exposed to high intensity earthquakes where the collapse of masonry claims the majority of casualties. This workshop provided a forum for discussion, including survey and measurement, retrofitting criteria and approaches used in different European countries.
