Book Description
This comprehensive treatise covers in detail practical methods of analysis as well as advanced mathematical models for structures highly sensitive to creep and shrinkage. Effective computational algorithms for century-long creep effects in structures, moisture diffusion and high temperature effects are presented. The main design codes and recommendations (including RILEM B3 and B4) are critically compared. Statistical uncertainty of century-long predictions is analyzed and its reduction by extrapolation is discussed, with emphasis on updating based on short-time tests and on long-term measurements on existing structures. Testing methods and the statistics of large randomly collected databases are critically appraised and improvements of predictions of multi-decade relaxation of prestressing steel, cyclic creep in bridges, cracking damage, etc., are demonstrated. Important research directions, such as nanomechanical and probabilistic modeling, are identified, and the need for separating the long-lasting autogenous shrinkage of modern concretes from the creep and drying shrinkage data and introducing it into practical prediction models is emphasized. All the results are derived mathematically and justified as much as possible by extensive test data. The theoretical background in linear viscoelasticity with aging is covered in detail. The didactic style makes the book suitable as a textbook. Everything is properly explained, step by step, with a wealth of application examples as well as simple illustrations of the basic phenomena which could alternate as homeworks or exams. The book is of interest to practicing engineers, researchers, educators and graduate students.

Book Description
This book provides a State of the Art Report (STAR) produced by RILEM Technical Committee 254-CMS ‘Thermal Cracking of Mas-sive Concrete Structures’. Several recent developments related to the old problem of understanding/predicting stresses originated from the evolution of the hydration of concrete are at the origin of the creation this technical committee. Having identified a lack in the organization of up-to-date scientific and technological knowledge about cracking induced by hydration heat effects, this STAR aims to provide both practitioners and scientists with a deep integrated overview of consolidated knowledge, together with recent developments on this subject.

Book Description
Today research on creep and shrinkage of concrete is diversified to such a degree that specialists working in different areas sometimes find it difficult to understand one-another. Materials scientists are mainly interested in processes on a microstructural level but they do not necessarily understand the relevance of time dependent deformation in structural design. On the other hand engineers who apply simplified model laws in non-elastic structural analysis are not always in the position to judge the limitations implied in their approach. It is generally realized that further development can be stimulated by a more effective exchange of results and ideas among the different groups involved. In an attempt to bridge this obvious gap in September 1980 there was a Conference organized at Swiss Federal Institute of Technology in Lausanne. The papers presented at this meeting covered the wide range starting with microstructural aspects and mechanisms and including constitutive modelling and structural creep analysis. These contributions together with summaries of two panel discussions are being published in this volume. All serious of the meeting have been introduced by invited lectures. These papers will be published in a special volume "Creep and Moisture Effects in Concrete". This special volume is rather to be a general survey of the different areas covered while the present conference proceedings provide a unique selection of research papers. Nowadays time-dependent deformation of concrete can be taken into consideration realistically by computerized structural analysis.

Book Description
This book deals with the chemical and physical properties of cements and concretes and their relation to the practical problems that arise in manufacturing and use. Much attention is given to the suitability of materials, to the conditions under which concrete may deteriorate, and to the precautionary or remedial measures that can be adapted.

Book Description
Widely used in the construction of bridges, dams and pavements, concrete and masonry are two of the world's most utilized construction materials. However, many engineers lack a proper understanding of the methods for predicting and mitigating their movements within a structure. Concrete and Masonry Movements provides practical methods for predicting and preventing movement in concrete and masonry, saving time and money in retrofitting and repair cost. With this book in hand, engineers will discover new prediction models for masonry such as: irreversible moisture expansion of clay bricks, elasticity, creep and shrinkage. In addition, the book provides up-to-date information on the codes of practice. - Provides mathematical modelling tools for predicting movement in masonry - Up-to-date knowledge of codes of practice methods - Clearly explains the factors influencing all types of concrete and masonry movement - Fully worked out examples and set problems are included at the end of each chapter

Book Description
Fire design of concrete structures has emerged in recent years as a high profile subject of great interest to both experts and the public. This has been largely prompted by severe damage to concrete in a number of recent tunnel fires, as well as a considerable amount of research and development that has taken place world-wide. fib Task Group 4.3, "Fire Design of Concrete Structures", therefore took the initiative to develop this bulletin in order to present the results of this international research to a wider group of concrete professionals. The report presents a general brief outline of the effect of fire on both concrete material and concrete structures, with emphasis placed on the important developments of the past few years, namely: (a) the increasing use of high strength concrete (HSC) in buildings, tunnels and bridges; (b) the growing acceptance of the use of performance based fire engineering calculations for the structural analysis and design against fire; (c) the problem of, and solutions to, explosive spalling; and (d) fires in tunnels. This report is not intended to be an exhaustive review of the effect of fire on concrete and concrete structures, nor to present a database of properties at high temperature. Instead, the main aims of this document are to present recent trends and developments, highlight key influencing factors, bring together the disparate but related issues in one short document, highlight the deficiencies in current practice and point to the future. The basic principles of performance based codes and fire engineering are also presented on the assumption that the reader is not a specialist in this field.

Book Description
Concrete is commonly regarded as a mundane, prosaic material whilst the sea is perceived as a fearsome environment, endowed with mystery. Mystery stems from lack of knowledge, and to that extent both concrete and sea have something in common-we fall a long way short of knowing enough about them. Fortunately we have learned enough from our investigations and experiences to be able to set the limits within which we should operate. It is important for the engineer to seek to quantify the effects of the environment on materials and structures so that these can be made safe and adequately durable for their intended economic life. This is especially true for marine structures. Thus the primary purpose of this book is to provide a useful synthesis of the behaviour of concrete and concrete structures in the marine environment. An outline of the content of the book is provided in the latter part of the first chapter and so will not be anticipated here. The chief aim throughout, however, is to work as far as possible within a context of the appropriate governing physical phenomena, giving due consideration to the mathematical relationships between them. Moreover, without intending to be a design manual, an introduction is given to the sources of information which designers are likely to use, as well as to structural achievements. It is hoped that there should emerge an implicit integration between structure and constituent materials and the surrounding environment.
