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.

Dear Colleagues, We are pleased to organize the Sixth International RILEM Symposium on SCC and the Fourth North-American Conference on the Design and Use of SCC, held on Sept 26-29, 2010 in Montreal, Quebec, Canada. The RILEM series of symposia started in 1999 in Stockholm, followed by Tokyo in 2001, Reykjavik in 2003, Chicago in 2005, and Ghent in 2007 with a steadily increasing number of papers, participants, and interest from across the globe. Due to the growing success of SCC, regional conferences have been organized, such as the North-American Conference on the Design and Use of SCC held in Chicago in 2002, 2005, and 2008; the International Symposium on Design, Performance and Use of SCC held nd in Changsa, China in 2005 and in Beijing, China in 2009; as well as the 2 International Conference on Advances in Concrete Technology in the Middle East: SCC held in Abu Dhabi in 2009. It can be concluded that these regional Conferences and Symposia were highly successful and reached a far more international audience than anticipated. Nearly 100 papers were submitted for these proceedings from which the International Scientific Committee selected 37 contributions covering a wide range of timely and original subjects from around the world. We would like to acknowledge the input of the International Scientific Committee for providing critical input to guarantee high quality of these peer-reviewed proceedings. We invite you to explore a wealth of information in the electronic proceedings.

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.

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.

This book expounds on progress made over the last 35 years in the theory, synthesis, and application of triboluminescence for creating smart structures. It presents in detail the research into utilization of the triboluminescent properties of certain crystals as new sensor systems for smart engineering structures, as well as triboluminescence-based sensor systems that have the potential to enable wireless, in-situ, real time and distributed (WIRD) structural health monitoring of composite structures. The sensor component of any structural health monitoring (SHM) technology - measures the effects of the external load/event and provides the necessary inputs for appropriate preventive/corrective action to be taken in a smart structure - sits at the heart of such a system. This volume explores advances in materials properties and structural behavior underlying creation of smart composite structures and sensor systems for structural health monitoring of critical engineering structures, such as bridges, aircrafts, and wind blades.

Focusing on techniques that limit the environmental impacts of the concrete industry, the text explores the use of recycled components in the place of virgin aggregates and ordinary binders. Chapters focus on topics including processing procedures, mixture proportioning, mechanical properties, durability and structural applications. Providing a valuable resource to engineering postgraduates and researchers, this book is also intended for civil engineers, geologists, and concrete engineers.

Wood is one of the most intriguing structural materials and the only one that is truly renewable. Along with stone, wood is the oldest structural material on the planet and has been extensively used throughout human history. Due to its aesthetical value and positive environmental impact, wood has experienced a renaissance in construction.

As a biodegradable, hygroscopic, non-isotropic material, wood presents special challenges for a professional and requires through knowledge ranging from biology to continuum mechanics.

This state-of-the-art report reflects the current knowledge in the area of in situ assessment of the physical and mechanical properties of wood structures. Nondestructive, semi-destructive and destructive methods are described in a systematic manner where technology, equipment and limitations are discussed. Some of the discussed methods are used in other materials such as masonry and concrete. Most of the methods, however, are specific to wood and special qualifications are required to understand and apply these methods effectively. Existing methods are constantly improved and new methods are being developed. This report includes methods that are used in practice or have shown significant promise and have a body of knowledge that supports statements made in this report.

The aim of this book is to investigate comfort control inside buildings, and how this can be achieved through low energy consumption. It presents a comprehensive exploration of the design, development and implementation of several advanced control systems that maintain users' comfort (thermal and indoor air quality) whilst minimizing energy consumption. The book includes a detailed account of the latest cutting edge developments in this area, and presents several control systems based on Model Predictive Control approaches. Real-life examples are provided, and the book is supplemented by illustrations, tables, all of which facilitate understanding of the text.

Energy consumption in buildings (residential and non-residential) represents almost the half of the total world energy consumption, and they are also responsible for approximately 35% of CO2 emissions. For these reasons, the reduction of energy consumption associated with the construction and use of buildings, and the increase of energy efficiency in their climatic refurbishment are frequently studied topics in academia and industry. As the productivity of users is directly related to their comfort, a middle ground needs to be found between comfort of users and energy efficiency. In order to achieve this, it is necessary to develop innovation and technology which can provide comfortable environments with minimum energy consumption. This book is intended for researchers interested in control engineering, energy and bioclimatic buildings, and for mechanical and process control engineers. It also accessible to postgraduate students embarking on a career in this area, particularly those studying architecture.

There is a strong need for a comprehensive textbook on construction technology for tall buildings, particularly in reference to land scarce countries and cities. This volume is particularly applicable to the construction industry in the Asean region, where rapid economic development in the last few decades has resulted in an unprecedented explosion in tail building development.

Containing over 200 illustrations, this book describes in detail the latest construction practices and processes for tall buildings from foundation to roof. The construction sequence of the various proprietary systems and their merits and disadvantages are discussed. Comprehensive references for each topic are also provided.

Currently, students and practitioners in the Asean region dealing with construction technology have to rely on textbooks written mainly in the US and UK, many of which are not relevant or not practical for use in the region because of different climate conditions.

This book is written for use as a textbook and reference book by undergraduates as well as practitioners in the fields of architecture, civil engineering, building, quantity surveying, and other related fields.
