This book presents new guidelines for the control of cracking in massive reinforced and prestressed concrete structures. Understanding this behavior during construction allows engineers to ensure properties such as durability, reliability, and water- and air-tightness throughout a structure’s lifetime. Based on the findings of the French national CEOS.fr project, the authors extend existing engineering standards and codes to advance the measurement and prediction of cracking patterns. Various behaviors of concrete under load are explored within the chapters of the book. These include cracking of ties, beams and in walls, and the simulation and evaluation of cracking, shrinkage and creep. The authors propose new engineering rules for crack width and space assessment of cracking patterns, and provide recommendations for measurement devices and protocols. Intended as a reference for design and civil engineers working on construction projects, as well as to aid further work in the research community, applied examples are provided at the end of each chapter in the form of expanded measurement methods, calculations and commentary on models.

This report contains technical and scientific information presented at the 4th workshop "Control of Cracking and Durability of Reinforced Concrete Structures", held on 20-21 March 2014 at the Joint Research Centre, Ispra, Italy. Co-sponsored by the Joint Research Centre, this event was the fourth of a series of "Control of Cracking" workshops (ConCrack) organised by the French research programme CEOS.fr. This programme was the framework set up by French professionals to make a decisive step in the predictive capacity of models to describe the state of cracking of buildings and civil engineering works, with the final objective of developing tools for designers and support the evolution of standards. The main purpose of the workshop was to improve engineering practices related to the cracking process in special massive concrete structures, thus enhancing the prediction of crack evolution during the service life of special structures. The international scientific and engineering community acknowledged the significance of the research findings and the practical results presented at the workshop enabling the exchange of expert know-how and codification. There was a strong motivation among participants to pursue further research work on the topic of cracking and durability of massive concrete structures, addressing aspects of cost, safety and sustainability.

Concrete structures must be designed not only to be safe against failure but also to perform satisfactorily in use. This book is written for practising engineers and students, and focuses on design methods for checking deflections and cracking which can affect the serviceability of reinforced and prestressed concrete structures. The authors present accurate and easy-to-apply methods of analysing immediate and long-term stresses and deformations. These methods allow designers to account for variations of concrete properties from project to project and from country to country, making the book universally applicable. Comprehensively updated, this third edition of Concrete Structures also includes four new chapters covering such topics as: non-linear analysis of plane frames, design for serviceability of prestressed concrete, serviceability of members reinforced with fibre polymer bars, and the analysis of time-dependent internal forces with linear computer programs that are routinely used by structural designers. A website accompanies the book, featuring three design calculation programs related to stresses in cracked sections, creep coefficients and time-dependent analysis. The book contains numerous examples, some of which are worked out in the SI units and others in the Imperial units. The input data and the main results are given in both SI and Imperial units. The book is not tied to any specific code, although the latest American and European codes of practice are covered in the appendices.

This report establishes a user's manual for the acceptance, repair, or rejection of precast/prestressed concrete girders with longitudinal web cracking. The report also proposes revisions to the AASHTO LRFD Bridge Design Specifications and provides recommendations to develop improved crack control reinforcement details for use in new girders. The material in this report will be of immediate interest to bridge engineers.

This highly successful textbook has been comprehensively revised for two main reasons: to bring the book up-to-date and make it compatible with BS8110 1985; and to take into account the increasing use made of microcomputers in civil engineering. An important chapter on microcomputer applications has been added.

PREFACE Teaching reinforced concrete design, carrying out research relevant to the behavior of reinforced concrete members, as well as designing concrete structures motivated the preparation of this book. This volume is considered part of a series of books that covers the subject of Reinforced Concrete Design. The success and the po.sitive feedbat;k that we have received from our students and colleagues have provided the inspiration for us to proceed with volume three. Due to the numerous changes in the provisions of the 2007 edition of the Egyptian Code of Practice ECP 203, the publication of this volume became more of a necessity than mere addition. The first vol.\.! covers the fundamentals of reinforced concrete design and the design of beams whereas the second volume focuses primarily on the design of slabs, columns and frames. This third volume covers the following topics: • Arches, Special Types of Frames and Vierendeel. • Deep Beams and Corbels. • Control of Deflections and Cracking. • Design of Shallow and Deep Foundations. • Strut-and-Tie Model. • Prestressed Concrete. Numerous illustrative examples are given, the solution of which has been supplied so as to supplement the theoretical background and to familiarize the reader with the steps involved in actual design problem solving. To ensure the accuracy, all of the examples in this book are solved and verified using EXCEL spread sheet programs that were prepared exclusively for this book. In writing the book, the authors are conscious of a debt to many sources, to friends, colleagues, and co-workers in the field. Finally, this is as good a place as any for the authors to express their indebtedness to their honorable professors of Egypt, Canada and the U.S.A. Their contributions in introducing the authors to the field will always be remembered with the deepest gratitude. The book is aimed at two different groups. First, by treating the material in a logical and unified form, it is hoped that it can serve as a useful text for undergraduate and graduate student courses on reinforced concrete. Secondly, as a result of the continuing activity in the design and construction of reinforced concrete structures, it will be of value to practicing structural engineers. The authors strongly recommend that the Code be utilized as a companion publication to this book.

Designed primarily as a text for undergraduate students of Civil Engineering for their first course on Limit State Design of Reinforced Concrete, this compact and well-organized text covers all the fundamental concepts in a highly readable style. The text conforms to the provision of the latest revision of Indian Code of Practice for Plain and Reinforced Concrete, IS : 456 (2000). First six chapters deal with fundamentals of limit states design of reinforced concrete. The objective of last two chapters (including design aids in appendix) is to initiate the readers in practical design of concrete structures. The text gives detailed discussion of basic concepts, behaviour of the various structural components under loads, and development of fundamental expressions for analysis and design. It also presents efficient and systematic procedures for solving design problems. In addition to the discussion of basis for design calculations, a large number of worked-out practical design examples based on the current design practices have been included to illustrate the basic principles of reinforced concrete design.Besides students, practising engineers would find this text extremely useful.
