It includes a specification for the use of polymer fluids and all the information necessary to optimise the use of these materials and the performance of the resulting foundation elements. Polymer Support Fluids in Civil Engineering covers all major aspects, from the fundamental material properties to site testing and case histories of polymer use. It is the first book to be published on polymer support fluids in the construction industry

Structural Analysis offers well-explained worked solutions which complement the discussed theory, allowing students to understand the logic behind the solution. This book covers the full breadth of this core topic including detailed chapter on Finite Element Analysis.

Optimization is generally a reduction operation of a definite quantity. This process naturally takes place in our environment and through our activities. For example, many natural systems evolve, in order to minimize their potential energy. Modeling these phenomena then largely relies on our capacity to artificially reproduce these processes. In parallel, optimization problems have quickly emerged from human activities, notably from economic concerns. This book includes the most recent ideas coming from research and industry in the field of optimization, reliability and the recognition of accompanying uncertainties. It is made up of eight chapters which look at the reviewing of uncertainty tools, system reliability, optimal design of structures and their optimization (of sizing, form, topology and multi-objectives) - along with their robustness and issues on optimal safety factors. Optimization reliability coupling will also be tackled in order to take into account the uncertainties in the modeling and resolution of the problems encountered. The book is aimed at students, lecturers, engineers, PhD students and researchers.

This book, by using SI units, makes finite elements more understandable in terms of fundamentals, provides the student with the background needed to extrapolate the finite element method to areas of study other than solid mechanics, and presents energy principles from a continuum viewpoint.

The structural analysis of multi-storey buildings can be carried out using discrete (computer-based) models or creating continuum models that lead to much simpler albeit normally approximate results. The book relies on the second approach and presents the theoretical background and the governing differential equations (for researchers) and simple closed-form solutions (for practicing structural engineers). The continuum models also help to understand how the stiffness and geometrical characteristics influence the three-dimensional behaviour of complex bracing systems. The back-of-the-envelop formulae for the maximum deflection and rotation, load shares, fundamental frequency and critical load facilitate quick global structural analysis for even large buildings. It is shown how the global critical load ratio can be used for monitoring the "health" of the structure acting as a performance indicator and "safety factor". Evaluating the results of over sixteen hundred calculations, the accuracy of the procedures is comprehensively demonstrated by comparing the discrete and continuum results. Nineteen worked examples illustrate the use of the methods, whose downloadable MathCad and Excel worksheets (www.crcpress.com/ 9780367350253) can also be used as templates for similar practical situations.

All rock masses contain bedding planes, fissures, fractures, joints and other mechanical defects which are here referred to as "discontinuities". The requirement to provide numerical data on discontinuities for engineering design calculations has created the need to apply the mathematical methods of probability theory, statistics, vector analysis and mechanics to a topic that has previously been handled in a largely qualitative way. This book aims to bridge the gap between the descriptive methods of the geologist and the analytical methods of the rock mechanics engineer as applied to discontinuity characteristics. It does not pretend to be the final word on the topic, but rather seeks to explain in simple terms, basic ideas that can be built upon. Advanced undergraduates studying civil, mining and geological engineering and postgraduates pursuing coursework in rock mechanics, soil mechanics and engineering geology should find this a valuable text. It should also serve as a reference tool for practising engineers and geologists faced with the task of collecting, analyzing and applying discontinuity data for the analysis and design of surface and underground excavations in rock associated with a wide range of mining and civil engineering projects. This book should be of interest to undergraduate students studying civil, mining and geological engineering; Msc and PhD students in rock mechanics, soil mechanics, engineering geology, hydro(geo)logy and related subjects; and practising engineers and geologists.

Concrete structures can be designed for durability by applying the principles and procedures of reliability theory combined with traditional structural design. This book is the first systematic attempt to introduce into structural design a general theory of structural reliability and existing calculation models for common degradation processes. It covers both the theoretical background and practical design for service life and includes worked examples which highlight the application of the design procedure and methods.

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.

One of the principal challenges in structural engineering concerns the development of innovative design concepts to better protect structures, together with their occupants and contents, from the damaging effects of destructive environmental forces including those due to winds, waves and earthquakes. Passive energy dissipation devices, when incorporated into a structure, absorb or consume a portion of the input energy,thereby reducing energy dissipation demand on primary structural members and minimizing possible structural damage. This book is a unified treatment of passive energy dissipation systems. Basic principles, mathematical modeling, practical considerations, implementation issues and structural applications are discussed for each major device type. Numerous examples and case studies are included.

The effect of combined extreme transient loadings on a structure is not well understood-whether the source is man-made, such as an explosion and fire, or natural, such as an earthquake or extreme wind loading. A critical assessment of current knowledge is timely (with Fukushima-like disasters or terrorist threats). The central issue in all these problems is structural integrity, along with their transient nature, their unexpectedness, and often the uncertainty behind their cause. No single traditional scientific discipline provides complete answers, rather, a number of tools need to be brought together: nonlinear dynamics, probability theory, some understanding of the physical nature of the problem, as well as modeling and computational techniques for representing inelastic behavior mechanisms. Nonlinear Dynamics of Structures Under Extreme Transient Loads covers model building for different engineering structures and provides detailed presentations of extreme loading conditions. A number of illustrations are given quantifying; a plane crash or explosion induced impact loading, the effects of strong earthquake motion, and the impact and long-duration effects of strong stormy winds-along with a relevant framework for using modern computational tools. The book considers the levels of reserve in existing structures, and ways of reducing the negative impact of high-risk situations by employing sounder design procedures.

A unique presentation of two key elements of structural design

Both damage tolerant design and nondestructive inspection are essential for achieving structural integrity, yet these interrelated disciplines are generally studied independently and implemented by different individuals within an organization. Fundamentals of Structural Integrity is an unparalleled presentation of both of these technologies in a single volume that points out the many interconnected details that must function in concert to assure the prevention of structural failures.

This groundbreaking volume introduces the concept of structural integrity and explains how it is achieved. It provides examples of threats to structural integrity, reviews structural certification policies, and presents detailed coverage of damage tolerant design procedures and nondestructive inspection methods. Outstanding features of this comprehensive guide include:

• In-depth discussions of crack tip plasticity issues and fatigue crack growth
• Methods for obtaining stress intensity factor solutions
• Procedures for anticipating service-induced fatigue and corrosion damage
• In-depth presentations of all major nondestructive inspection techniques
• Coverage of inspection intervals and residual strength
• U.S. Air Force AFGROW life prediction software included on the associated Web site

Fundamentals of Structural Integrity is an indispensable resource for mechanical, materials, civil, and aerospace engineers charged with researching, designing, or maintaining safe operation of high-performance structures.

Features: Examines the probability of several types of structural failure and includes reliability analysis. Presents best practices for predicting the structural lifetime for both onshore and offshore structures and reviews the most advanced methods for repair. Includes numerous practical case studies of structural failure and offers mitigation strategies depending of type of structure.

In the rapid expansion of the construction industry during the 1960s basic advice regarding cover to reinforcement and impermeability of concrete to moisture for subsequent durability often went unheeded. Today the UK is seeing the result and similar effects are being observed worldwide. The book draws together experts from the fields of concrete durability, repair and protection to provide a state-of-the-art review on current thinking, materials and techniques. The basic deterioration mechanisms and methods for the site investigation of distressed concrete structures are initially considered. Materials and techniques for repair are critically reviewed and relatively novel ideas for protection are discussed. The second part of the book is presented as a series of case studies for various structure types. They are written by those who have immediate experience of both the technical and financial difficulties of concrete repair and maintenance programmes. This book should be of interest to civil and structural engineers in consulting engineering firms, contractors and local authorities, repair materials suppliers and technologists, building surveyors and architects, lecturers and stu

Additionally, this topic covers research on novel or existing construction materials and systems based on local resources and regional practices. The following subtopics are included: industrialized construction systems minimizing waste; recycling and reuse of materials and components; 4Ls: local constructions with local materials through local approaches for local development; Digital Manufacturing; design for deconstruction; smart demolition techniques; timber structures; Life-Cycle Assessment of construction materials and technologies; recycling of pavements and materials in roads.

Many types of structure are subject to maritime conditions, and construction and maintenance of coastal structures is a major part of the construction workload of any country bordering the sea. This book is a comprehensive source of information for all who are concerned with the commissioning, design, construction or maintenance of concrete structures in or near the sea. As well as describing the nature of the marine environment and the effects of man-made structures on the behaviour of the sea, this books deals with hydraulic design, the material properties of concrete and the design and specification of structures for coastal environments. The deterioration of concrete in coastal structures is usually a result of lack of durability rather than overloading, so much of the book has been directed towards the production of durable structures. British standards and other standards and codes from around the world are discussed, along with the planning of construction works under coastal conditions, and the maintenance of coastal structures. All of the chapters were written specially for this book by practising engineers with specialised knowledge and wide experience of coastal engineering. As most of the authors have been responsible for work in many parts of the world, this book is relevant regardless of where coastal structures are situated.
