In the past, facilities considered to be at the end of their useful life were demolished and replaced with new ones that better met the functional requirements of modern society, including new safety standards. Humankind has recently recognised the threats to the environment and to our limited natural resources due to our relentless determination to destroy the old and build anew. With the awareness of these constraints and the emphasis on sustainability, in future the majority of old structures will be retrofitted to extend their service life as long as feasible. In keeping with this new approach, the EU s Construction Products Regulation 305/2011, which is the basis of the Eurocodes, included the sustainable use of resources as an "Essential Requirement" for construction. So, the forthcoming second generation of EN-Eurocodes will cover not only the design of new structures, but the rehabilitation of existing ones as well.
Most of the existing building stock and civil infrastructures are seismically deficient. When the time comes for a decision to prolong their service life with the help of structural and architectural upgrading, seismic retrofitting may be needed. Further, it is often decided to enhance the earthquake resistance of facilities that still meet their functional requirements and fulfil their purpose, if they are not earthquake-safe. In order to decide how badly a structure needs seismic upgrading or to prioritise it in a population of structures, a seismic evaluation is needed, which also serves as a guide for the extent and type of strengthening. Seismic codes do not sufficiently cover the delicate phase of seismic evaluation nor the many potential technical options for seismic upgrading; therefore research is on-going and the state-of-the-art is constantly evolving. All the more so as seismic evaluation and rehabilitation demand considerable expertise, to make best use of the available safety margins in the existing structure, to adapt the engineering capabilities and techniques at hand to the particularities of a project, to minimise disruption of use, etc. Further, as old structures are very diverse in terms of their materials and layout, seismic retrofitting does not lend itself to straightforward codified procedures or cook-book approaches. As such, seismic evaluation and rehabilitation need the best that the current state-of-the-art can offer on all aspects of earthquake engineering. This volume serves this need, as it gathers the most recent research of top seismic experts from around the world on seismic evaluation, retrofitting and closely related subjects."

This book focuses on the impacts of the built environment, and how to predict and measure the benefits and consequences of changes taking place to address sustainability in the development and building industries. It draws together the best treatments of these subjects from the Leeds Sustainability Institute's inaugural International Conference on Sustainability, Ecology, Engineering, Design for Society (SEEDS). The focus of discussion is on understanding how buildings and spaces are designed and nurtured to obtain optimal outcomes in energy efficiency and environmental impacts. In addition to examining technical issues such as modeling energy performance, emphasis is placed on the health and well-being of occupants. This holistic approach addresses the interdependence of people with the built and natural environments. The book's contents reflect the interdisciplinary and international collaboration critical to assembly of the knowledge required for positive change.

Oak-framed Buildings is a practical and inspiring guide to their design and construction, written by expert craftsman Rupert Newman. Oak-framed buildings have been with us for centuries and they are here to stay. They are beautiful, durable and environmentally friendly, and by marrying traditional and modern materials they can be brought to a very high standard of energy-efficiency. This is a practical book on the technique of timber-frame construction for carpenters, builders and aspiring self-builders, but it will also be a source of inspiration to anyone who appreciates beautiful buildings. Full-colour photographs show projects by the author and others both complete and under construction, and structural details are clearly explained both in photographs and in three-dimensional drawings. Here is a traditional craft brought fully up to date for the 21st century. Topics covered include: past and present, making a start, understanding the structure, frame design, the construction process, raising the frame, walls and roofs, second fix, finishing off, and future of timber building.

This book examines pedestrian shoe-floor slip resistance from an engineering standpoint in order to better understand friction and wear behavior. This analysis includes an extensive investigation into the surface properties of shoes and flow, and the measurement of dynamic friction and other mechanical and physical aspects of shoe-floor tribology. Lastly, the book proposes a measurement concept for the identification and classification of operational floor surfaces under a range of different conditions. Novel techniques and methods are proposed that can improve the reliability of slip resistance assessments. The current state of knowledge is critically examined and discussed from a tribological perspective, including aspects like friction, wear, lubrication and the mechanical behavior of shoes, floors and their wider environment. Further, the book reports on extensive experimental investigations into the topographical characteristics of shoe and floor surfaces and how they affect slip resistance. Slips resulting in pedestrian falls are a major cause of injuries and deaths for all age groups. This important book provides essential insights for researchers, practicing engineers and public safety officials wishing to learn about how the risk of pedestrian slips can be assessed and understood.

This book focuses on the implementation of Quality Function Deployment (QFD) in the construction industry as a tool to help building designers arrive at optimal decisions for external envelope systems with sustainable and buildable design goals. In particular, the book integrates special features into the conventional QFD tool to enhance its performance. These features include a fuzzy multi-criteria decision-making method, fuzzy consensus scheme, and Knowledge Management System (KMS). This integration results in a more robust decision support tool, known as the Knowledge-based Decision Support System QFD (KBDSS-QFD) tool. As an example, the KBDSS-QFD tool is used for the assessment of building envelope materials and designs for high-rise residential buildings in Singapore in the early design stage. The book provides the reader with a conceptual framework for understanding the development of the KBDSS-QFD tool. The framework is presented in a generalized form in order to benefit building professionals, decision makers, analysts, academics and researchers, who can use the findings as guiding principles to achieve optimal solutions and boost efficiency.

Huge earthquakes and tsunamis have caused serious damage to important structures such as civil infrastructure elements, buildings and power plants around the globe. To quantitatively evaluate such damage processes and to design effective prevention and mitigation measures, the latest high-performance computational mechanics technologies, which include telascale to petascale computers, can offer powerful tools. The phenomena covered in this book include seismic wave propagation in the crust and soil, seismic response of infrastructure elements such as tunnels considering soil-structure interactions, seismic response of high-rise buildings, seismic response of nuclear power plants, tsunami run-up over coastal towns and tsunami inundation considering fluid-structure interactions. The book provides all necessary information for addressing these phenomena, ranging from the fundamentals of high-performance computing for finite element methods, key algorithms of accurate dynamic structural analysis, fluid flows with free surfaces, and fluid-structure interactions, to practical applications with detailed simulation results. The book will offer essential insights for researchers and engineers working in the field of computational seismic/tsunami engineering.

The weathering of historical buildings and, indeed, of monuments and sculptures of natural stone is a problem that has been encountered for hundreds of years. However a dramatic increase in deterioration in the structure of our built heritage has been observed during the past century. To understand the complex interaction that the stone in a building suffers with its near environment (the building) and the macro environment (the local climate and atmospheric conditions) requires an interdisciplinary approach and the application of many disciplines. Climate change over the next 100 years is likely to have a range of direct and indirect impacts on many natural and physical environments, including the built environment.

The protection of our architectural heritage has both cultural and historical importance, as well as substantial economic and ecological value. Large sums of money are being spent world-wide on measures for the preservation of monuments and historical buildings. The past few decades has seen an unprecedented level of research activity in this area, the result of whichis often difficult to access and are summarized in the new edition of STONE IN ARCHITECTURE.

The 4th edition of Stone in Architecture: Properties, Durability, is a sophisticated and thorough exploration of stone its properties, performance and conservation in monumental contexts. The current editors, Siegfried Siegesmund and Rolf Snethlage, note the pioneering work of Erhard Winkler who wrote the first edition in 1973 when so little information could be found in the literature on the subject. This new edition, also published by Springer, nearly doubles the size of Winkler s 1994 effort. If you are familiar with the field and need to know little more than this statement, you can put aside this review and go buy the book.

This study presents exploratory work and seeks to identify and evaluate the success and failure factors that could form a guideline for further study and to some extent help professionals to understand some critical aspects that impact project performance concerning construction in India. A total of 55 attributes affecting the performance of construction projects are analysed in terms of their level of influence on four key performance criteria - schedule, cost, quality, and no disputes - using a two-stage questionnaire survey. These attributes are then further analysed, interpreted and evaluated. Based on the critical success factors obtained from the study, a neural network model-based predictive model for project performance has been developed. The performance prediction models have been derived for all four project performance criteria. Further, a hypothesis that 'project success' is influenced by 'success traits' has also been formulated. The hypothesized positive inter-relationships between success traits and project success have been tested using the structural equation modelling technique. Besides supporting the intuition of past researchers in recognizing 'coordination' as a key success factor, this study has revealed that coordination is not an isolated and independent activity, but is a typical management function with an inherent role in all major management activities. Key elements affecting coordination have also been identified and their influence on coordination effort has been studied. Furthermore, the present study has also identified three broad skill groups required of effective project coordinators. The results are validated through case studies of live projects and structured interviews with experts in the field of construction management.

Cementitious materials, rocks and fibre-reinforced composites commonly termed as "quasibrittle," need a different fracture mechanics approach to model the crack propagation study because of the presence of significant size of fracture process zone ahead of the crack-tip. Recent studies show that concrete structures manifest three important stages in fracture process: crack initiation, stable crack propagation and unstable fracture or failure. Fracture Mechanics concept can better explain the above various stages including the concepts of ductility, size-effect, strain softening and post-cracking behavior of concrete and concrete structures.

The book presents a basic introduction on the various nonlinear concrete fracture models considering the respective fracture parameters. To this end, a thorough state-of-the-art review on various aspects of the material behavior and development of different concrete fracture models is presented. The development of cohesive crack model for standard test geometries using commonly used softening functions is shown and extensive studies on the behavior of cohesive crack fracture parameters are also carried out. The subsequent chapter contains the extensive study on the double-"K" and double-"G" fracture parameters in which some recent developments on the related fracture parameters are illustrated including introduction of weight function method to Double-"K" Fracture Model and formulization of size-effect behavior of the double-"K" fracture parameters. The application of weight function approach for determining of the "KR"-curve associated with cohesive stress distribution in the fracture process zone is also presented. Available test data are used to validate the new approach. Further, effect of specimen geometry, loading condition, size-effect and softening function on various fracture parameters is investigated. Towards the end, a comparative study between different fracture parameters obtained from various models is presented."

The volume is devoted to the dynamics of rods, which is a branch of mech- ics of deformable bodies. The main goal of the book is to present systema- cally theoretical fundamentals of the mechanics of rods as well as numerical methods used for practical purposes. Linear and nonlinear equations governing a rod's oscillations are p- sented. Methods of determining eigenvalues and eigenfunctions in conser- tive and non-conservative problems along with numerical methods dealing with forced, parametric, and random oscillations of rods are given. Some - sues of interaction of rods with air (liquid) flows and the dynamics of spa- curved rods containing flows of liquid are considered. The book consists of nine chapters and appendices and may be conv- tionally divided into two parts. That is, Chapters 1 to 6 contain, in the main, theoretical material, whereas Chapters 7 to 9 illustrate the application of the theoretical results to problems of practical interest. Problems for self-study are found in Chapters 3, 5, and 7. The solutions to most of the problems are given in Appendix B. The monograph is addressed to undergraduate and postgraduate students and teaching staff of technical universities. It may also be useful for scientists and mechanical engineers working in a wide range of industries. I wish to express my deep appreciation to my colleagues, Dr. S.A. Voronov and C.B. Danilenko, for their help in preparing the manuscript.

The First African InterQuadrennial ICF Conference "AIQ-ICF2008" on Damage and Fracture Mechanics - Failure Analysis of Engineering Materials and Structures," Algiers, Algeria, June 1-5, 2008 is the first in the series of InterQuadrennial Conferences on Fracture to be held in the continent of Africa. During the conference, African researchers have shown that they merit a strong reputation in international circles and continue to make substantial contributions to the field of fracture mechanics. As in most countries, the research effort in Africa is und- taken at the industrial, academic, private sector and governmental levels, and covers the whole spectrum of fracture and fatigue. The AIQ-ICF2008 has brought together researchers and engineers to review and discuss advances in the development of methods and approaches on Damage and Fracture Mechanics. By bringing together the leading international experts in the field, AIQ-ICF promotes technology transfer and provides a forum for industry and researchers of the host nation to present their accomplishments and to develop new ideas at the highest level. International Conferences have an important role to play in the technology transfer process, especially in terms of the relationships to be established between the participants and the informal exchange of ideas that this ICF offers.

Optimization techniques offer immense potential for the improvement of performance-driven design, since they allow the adoption of an holistic approach. This can lead to great advantages: optimal design solutions can be properly identified only if all criteria are considered at the same time, rather than separately. There are two barriers which obstruct optimization from being applied to building design: a technological barrier (applying the algorithms is not easy and can be quite time-consuming) and a cultural one (architects and engineers are required to change their perspectives as the design process has to be handled in a new way). This book explores these barriers from the perspective of both engineers and architects, and proposes a change in the attitudes of these two "actors": an engineer and an architect develop a dialog which helps them understand each other's perspective; in this way they find how they must both make a step forward.

Masonry constructions are the great majority of the buildings in Europe's historic centres and the most important monuments of its architectural heritage. Given the age of these constructions, the demand for safety assessments and restoration projects is pressing and constant; still within the broad studies in the subject it is not yet recognised, in particular within the seismic area, a unitary approach to deal with Masonry structures. This successful book contributes to clarify the issues with a rigorous approach offering a comprehensive new Statics of Masonry Constructions. This third edition has been driven by some recent developments of the research in the field, and it gives the fundamentals of Statics with an original and rigorous mathematical formulation, further in-depth inquired in this new version. With many refinements and improvements, the book investigates the static behaviour of many historic monuments, such as the Gothic Cathedrals, the Mycenaean Tholoi, the Pantheon, the Colosseum, the domes of Santa Maria del Fiore in Florence and St Peter's in Rome, as well as the Leaning Tower of Pisa. The last chapter - the 11th - regarding the behaviour of masonry buildings under seismic actions, has been modified and integrated in order to take into account the numerous recent achievements of the research in the dynamic and seismic analysis. The focal point is that there's no dissipation of energy during the deformation of masonry structures, even if accompanied by cracks. If properly reinforced, masonry constructions have the sole resource to escape the seismic action developing the rocking without failure, under alternate seismic action. In this context, the rocking of pier walls, the main resistant components of the masonry structure, has been here thoroughly examined. Furthermore, the out of plane and the in-plane seismic strengths of masonry walls with openings has been investigated within the framework of Limit Analysis. Through an interdisciplinary approach, involving Mathematics, Engineering and Architecture, this book highlights the tight connection existing between the Statics of Masonry constructions and the principles that ruled the history of constructions, since the beginnings as far as the Seventeenth century.

When Seon (Zen) Buddhism was first introduced to Korea around Korea's late Silla and early Goryeo eras, the function of the "beopdang" (Dharma hall) was transfused to the lecture hall found in ancient Buddhist temples, establishing a pivotal area within the temple compound called the "upper monastic area." By exploring the structural formation and dissolution of the upper monastic area, the author shows how Korea established its own distinctive Seon temples, unlike those of China and Japan, in the course of assimilating a newly-introduced foreign culture as its own. To accomplish this, the author analyzed the inscriptions on stone monuments which recorded the lives of eminent monks and also numerous excavated temple ruins. These analyses give us a new perspective on the evolution of the upper monastic area, which had the beopdang as its center, at a time when early Seon temples were being established under very adverse and unstable circumstances. The exploration of the spatial organization and layout of Korean Seon temple architecture has illuminated the continuity between Korean Buddhist temples of both the ancient and medieval eras.

By the beginning of the nineteenth century, over ninety-five percent of all the productive land in Ireland was in the hands of Anglo-Irish landowners. They lived in the 'big houses', some of which still exist today, resplendent within their walled estates. Many others are now only gaunt ruins silhouetted against somber Irish skies, victims of 'the troubles' in the 1920s. There is a continuing fascination with the history of the big house in Ireland. Much of this interest stems from the Anglo-Irish living in places apart, in their estates, often in remote areas of an undeveloped and hostile land. Part of the appeal is in the characters, neither wholly English nor Irish, who made up this landowning class in Ireland. However, another part, largely ignored until this study, is how many of these landowners not only met these challenges but achieved remarkable levels of self-sufficiency. It was their exploitation of technology that hugely bolstered their status and independence and enabled them to lead an exotic lifestyle in Ireland. Although much has been written regarding the social and political history of the Anglo-Irish in Ireland, little research has been conducted into the practical problems of living there. At a time when there were few roads, no railways, and sailing ships were the unreliable connection with England, existence might have been very basic indeed. Charles Carson uncovers and explains in simple terms the technologies employed, to not only make life bearable, but in some case to become a triumph over seemingly impossible odds. An appreciation of this background helps to explain the sense of status and independence that emanates from the big house in Ireland until their demise in the late twentieth century. Interdisciplinary investigative methods were used in this work. These included extensive archival research of estate papers throughout Ireland; fieldwork involving examination and photography of still-extant big house technology; and the use of published fictional and biographical big house material. Much additional insight, and suggestions for further research, resulted from visits to various big house locations. Owners, often descendants of the original families, or managers and ground staff, provided important local knowledge. Climbing amongst stored artefacts in cellars, barns, and subterranean tunnels helped to bring the past alive. Something of the ambiance of these explorations informs this book, thus helping towards an understanding of the fundamental importance of technology in underpinning the status and independence of the big house in Ireland. By examining the range, costs, and changing nature of the technologies employed, this book makes an important contribution to a deeper understanding of life in the big house in Ireland circa 1800 to circa 1930. Brief descriptions, accompanied by drawings or photographs, are employed to explain the operation, limitations, and improvements of many of the installations and techniques. These include water closets, pumps, cisterns, boilers, and firefighting equipment; open fires, hot air stoves, and central heating; walled gardens, hot walls and beds, warm air, steam, and hot water heating of glasshouses; the construction, location, stocking, and use of ice houses and ice; daylight enhancement, candle, oil, gas, and electric lighting; an optical telegraph, a church spire, engine driven equipment on the estate farm as well as mapping of bogs and their reclamation by wooden railways. Technology and the Big House in Ireland, c. 1800-c. 1930 is an important reference source for Irish study groups worldwide.

The main purpose of this book, Hygrothermal, Building Pathology and Durability, is to provide a collection of recent research works to contribute to the systematization and dissemination of knowledge related to construction pathology, hygrothermal behaviour of buildings, durability and diagnostic techniques and, simultaneously, to show the most recent advances in this domain. It includes a set of new developments in the field of building physics and hygrothermal behaviour, durability approach for historical and old buildings and building pathology vs. durability. The book is divided in several chapters that are a resume of the current state of knowledge for benefit of professional colleagues, scientists, students, practitioners, lecturers and other interested parties to network.

This book provides a general introduction to the topic of buildings for resistance to the effects of abnormal loadings. The structural design requirements for nuclear facilities are very unique. In no other structural system are extreme loads such as tornadoes, missile and loud interaction, earthquake effects typical in excess of any recorded historical data at a site, and postulated system accident at very low probability range explicitly, considered in design. It covers the whole spectrum of extreme load which has to be considered in the structural design of nuclear facilities and reactor buildings, the safety criteria, the structural design, the analysis of containment. Test case studies are given in a comprehensive treatment. Each major section contains a full explanation which allows the book to be used by students and practicing engineers, particularly those facing formidable task of having to design complicated building structures with unusual boundary conditions.

This book is devoted to two primary objectives. The first is to present the errors, inadaptability and mistakes arising when the current theory on concrete is applied to explaining practical construction of concrete; the second is to put forward viewpoints in modern concrete science. Taking a number of engineering cases as examples, we experimentally studied and theoretically analyzed the errors, inadaptability, and mistakes when the current theory on concrete is applied to explaining practical construction of concrete. Moreover, we investigated the use of mixing ratios, aggregates, cement, high-performance concrete and fibers, as well as the frost resistance, cracking behavior, durability, dry shrinkage and autogenous healing to address and remedy the shortcomings in today's concrete science, put forward new proposals and make a number of innovative achievements in the field, particularly in modern theory on concrete science. The results and topics which will be of particular interest to engineers and researchers include: corrections to several one-sided, even mistaken views on concrete construction in the field and a new theory that can be adopted to improve the durability of concrete projects, to control and improve the implementation quality of concrete projects and to guide teaching in universities.

In this volume scientists from different disciplines present their experience and their scientific work in progress. These concern the properties of a series of stones that have been used for the erection of some of the most important stone monuments of international cultural heritage and are also used today for substitution of missing parts or completion of damaged ones. It deals with the subject globally and contains unpublished research results.

Cumulative impacts on construction projects remain largely an ill-defined concept. A more thorough understanding of cumulative impacts as defined by the construction industry and courts and boards will aid the contractor in preparing its damages and proving causation. The information herein provides a blueprint for the contractor seeking to recover costs that result from disruption and the cumulative impact of changes. Conversely, information is also provided that can be used by the owner to identify weaknesses in the contractor's claim submittal to better defend against a cumulative impact claim.

These proceedings include most of the available information on this major seismic event and its consequences. With an estimated moment magnitude of 7.7 and a heavy toll in terms of human and economic losses, it ranks as the largest intermediate-depth earthquake in Europe in the twentieth century. Nevertheless, because of the difficult conditions in the 1940s, the lessons learnt after the Vrancea earthquake were not extensively shared with the international scientific community and thus, this book fills a gap in the literature discussing the knowledge acquired after major disasters. Past experience together with current understanding of the 1940 Vrancea earthquake are presented along with the latest information on Romanian seismicity, seismic hazard and risk assessment, and seismic evaluation and rehabilitation of buildings and structures. Moreover, it includes excerpts from Romanian post-disaster reports and textbooks concerning the earthquake.

This timely book introduces architects, engineers, builders, and urban planners to a range of contemporary community design concepts and illustrates them with outstanding case studies from around the world. Drawing on successful projects from London, New Mexico, Austria, and the Netherlands, "Innovative Sustainable Communities" presents planning concepts that minimize developments' carbon footprint through compact communities, adaptable and expandable dwellings, edible landscape, and smaller-sized yet quality designed housing.
