Structural engineers must focus on a structure’s continued safety throughout its service life. Reinforced Concrete Structural Reliability covers the methods that enable engineers to keep structures reliable during all project phases, and presents a practical exploration of up-to-date techniques for predicting the lifetime of a structure. The book also helps readers understand where the safety factors used come from and addresses the problems that arise from deviation from these factors. It also examines the question of what code is best to follow for a specific project: the American code, the British Standard, the Eurocode, or other local codes. The author devotes an entire chapter to practical statistics methods and probability theory used in structural and civil engineering, both important for calculating the probability of structural failure (reliability analysis). The text addresses the effects of time, environmental conditions, and loads to assess consequences on older structures as well as to calculate the probability of failure. It also presents the effects of steel bar corrosion and column corrosion, and precautions to consider along with guides for design. This book offers guidelines and tools to evaluate existing as well as new structures, providing all available methods and tests for assessing structures, including visual inspection and nondestructive testing for concrete strength. It also presents techniques for predicting the remaining service life of a structure, which can be used to determine whether to perform repairs or take other action. This practical guide helps readers to differentiate between and understand the philosophy of the various codes and standards, enabling them to work anywhere in the world. It will aid engineers at all levels working on projects from the design to the maintenance phase, increasing their grasp of structure behavior, codes and factors, and predicting service life.

Steel-reinforced concrete is used ubiquitously as a building material due to its unique combination of the high compressive strength of concrete and the high tensile strength of steel. Therefore, reinforced concrete is an ideal composite material that is used for a wide range of applications in structural engineering such as buildings, bridges, tunnels, harbor quays, foundations, tanks and pipes. To ensure durability of these structures, however, measures must be taken to prevent, diagnose and, if necessary, repair damage to the material especially due to corrosion of the steel reinforcement. The book examines the different aspects of corrosion of steel in concrete, starting from basic and essential mechanisms of the phenomenon, moving up to practical consequences for designers, contractors and owners both for new and existing reinforced and prestressed concrete structures. It covers general aspects of corrosion and protection of reinforcement, forms of attack in the presence of carbonation and chlorides, problems of hydrogen embrittlement as well as techniques of diagnosis, monitoring and repair. This second edition updates the contents with recent findings on the different topics considered and bibliographic references, with particular attention to recent European standards. This book is a self-contained treatment for civil and construction engineers, material scientists, advanced students and architects concerned with the design and maintenance of reinforced concrete structures. Readers will benefit from the knowledge, tools, and methods needed to understand corrosion in reinforced concrete and how to prevent it or keep it within acceptable limits.

The corrosion of reinforcing steel in concrete is a major problem facing civil engineers and surveyors throughout the world today. There will always be a need to build stuctures in corrosive environments and it is therefore essential to address the problems that result. Corrosion of Steel in Concrete provides information on corrosion of steel in atmospherically exposed concrete structures and serves as a guide for those designing, constructing and maintaining buildings, bridges and all reinforced concrete structures. The present state of knowledge of corrosion of steel in concrete is reveiwed from theory, through to site investigations using the currently available corrosion assessment equipment. There is also a section on building structures to be more corrosion resistant and new developments we can expect. This is a book to educate and guide engineers, surveyors, students and owners of structures so that they will have a clearer idea of the problems of corrosion, its causes and how to find solutions

The Second International Conference on Concrete Repair, Rehabilitation and Retrofitting (ICCRRR 2005) was held in Cape Town, South Africa, from 24-26 November 2008. The Conference followed the very successful First International Conference, also in Cape Town in 2005, and continued as a collaborative venture by researchers from the South African Research Programme in Concrete Materials (based at the Universities of Cape Town and The Witwatersrand) and The Construction Materials Sections at Leipzig University and MFPA Leipzig in Germany. The background, in industry and the state of national infrastructures, continues to be highly challenging and demanding. The facts remain that much of our concrete infrastructure deteriorates at unacceptable rates, that we need appropriate tools and techniques to undertake the vast task of sound repair, maintenance and rehabilitation of such infrastructure, and that all this must be undertaken with due cognisance of the limited budgets available for such work. New ways need to be found to extend the useful life of concrete structures cost-effectively. Confidence in concrete as a viable construction material into the 21st century needs to be retained and sustained, particularly considering the environmental challenges that the industry and society now face. The conference proceedings contain papers, presented at the conference, and classified into a total of 12 sub themes which can be grouped under the three main themes of (i) Concrete durability aspects, (ii) Condition assessment of concrete structures, and (iii) Concrete repair, rehabilitation and retrofitting. The major interests in terms of submissions exists in the fields of innovative materials for durable concrete construction, integrated service life modelling of reinforced concrete structures, NDE/NDT and measurement techniques, repair methods and materials, and structural strengthening and retrofitting techniques. The large number of high-quality papers presented and the wide range of relevant topics covered confirm that these proceedings will be a valued reference for many working in the important fields of concrete durability and repair, and that they will form a suitable base for discussion and provide suggestions for future development and research. Set of book of abstracts (476 pp) and a searchable full paper CD-ROM (1396 pp).

This Digest is in three Parts. Part 1 examines the durability of steel in concrete. With Part 2 on investigation and assessment, and Part 3 on protection and remedial work, it sets out the basic principles for all those concerned with the design and maintenance of durable concrete structures: owners, tenants on repairing leases, architects, surveyors, engineers, material scientists and contractors. It also examines existing standards of construction and the lessons learned from the investigation of cases of corrosion in concrete. This part of the Digest, Part 1, explains the physical, chemical and electrochemical processes involved in the deterioration of reinforced concrete by corrosion; it summarises the mechanisms underlying protection, considers issues associated with the durability management of existing structures, and reviews best practice in designing and specifying reinforced and prestressed concrete for new structures to achieve durable whole-life performance. Part 2 considers how corrosion-induced deterioration in existing steel reinforced concrete structures is assessed and diagnosed. Part 3 describes the repair and protection of concrete structures subject to corrosion damage, or which are expected to need measures to minimise future damage or deterioration. Concrete durability is an area which is undergoing rapid technical development and change; this Digest describes future developments that are expected to have a major influence on the approaches and methodologies in this field. Digests 263, 264 and 265 are withdrawn.
