Failures In Concrete Structures

Some lessons are only learned from mistakes but, it‘s much cheaper to learn from someone else‘s mistakes than to have to do so from your own. Drawing on over fifty years of working with concrete structures, Robin Whittle examines the problems which he has seen occur and shows how they could have been avoided. The first and largest part of the

Understanding and recognising failure mechanisms in concrete is a fundamental pre-requisite to determining the type of repair, or whether a repair is feasible. This title provides a review of concrete deterioration and damage, as well as looking at the problem of defects in concrete. It also discusses condition assessment and repair techniques. Part one discusses failure mechanisms in concrete and covers topics such as causes and mechanisms of deterioration in reinforced concrete, types of damage in concrete structures, types and causes of cracking and condition assessment of concrete structures. Part two reviews the repair of concrete structures with coverage of themes such as standards and guidelines for repairing concrete structures, methods of crack repair, repair materials, bonded concrete overlays, repairing and retrofitting concrete structures with fiber-reinforced polymers, patching deteriorated concrete structures and durability of repaired concrete. With its distinguished editor and international team of contributors, Failure and repair of concrete structures is a standard reference for civil engineers, architects and anyone working in the construction sector, as well as those concerned with ensuring the safety of concrete structures.

Some lessons are only learned from mistakes but, it’s much cheaper to learn from someone else’s mistakes than to have to do so from your own. Drawing on over fifty years of working with concrete structures, Robin Whittle examines the problems which he has seen occur and shows how they could have been avoided. The first and largest part of the book tells the stories of a number of cases where things have gone wrong with concrete structures. Each case is analyzed to identify its cause and how it might have been prevented. It then looks at how failures in structural modelling can lead to big problems if they are not identified before construction is undertaken. Beyond this it examines how contract arrangements can encourage or prevent problems in the designing and building processes. It concludes with an examination of the role research and development in preventing failures. By identifying the differences between shoddy economizations and genuine efficiency savings, this book offers savings in the short term which won’t be at the expense of a structure’s long-term performance. Invaluable reading if you’re designing or building concrete structures and want to avoid problems which could be expensive or embarrassing further down the line.

Reinforced concrete has the potential to be very durable and capable of withstanding a variety of adverse environmental conditions. However, failures in the structures do still occur as a result of premature reinforcement corrosion. In this authoritative book the fundamental aspects of this complex process are analysed; focusing on corrosion of the reinforcing steel, and looking particularly, at new scientific and technological developments. Monitoring techniques, including the newly developed online-monitoring, are examined, as well as the numerical methods used to simulate corrosion and perform parameter studies. The influence of composition and microstructure of concrete on corrosion behaviour is explored. The second half of the book, which deals with corrosion prevention methods, starts with a discussion on stainless steels as reinforcement materials. There are comprehensive reviews of the use of surface treatments and coatings, of the application of corrosion inhibitors and of the application of electrochemical techniques. In each case the necessary scientific fundamentals are explained and practical instances of use are looked at. This is an invaluable guide for engineers, materials scientists and researchers in the field of structural concrete. Fundamental aspects of corrosion in concrete are analysed in detail Explores how to minimise the effects of corrosion in concrete Invaluable guide for engineers, materials scientists and researchers in the field of structural concrete

First published in 1968, Jacob Feld's Construction Failure has longbeen considered the classic text on the subject. Retaining all ofthe key components of Feld's comprehensive exploration of the rootcauses of failure, this Second Edition addresses a multitude ofimportant industry developments to bring this landmark work up todate for a new generation of engineers, architects, andstudents. In addition to detailed coverage of current design tools,techniques, materials, and construction methods, ConstructionFailure, Second Edition features an entire chapter on theburgeoning area of construction litigation, including a thoroughexamination of alternative dispute resolution techniques. Like theoriginal, this edition discusses technical and procedural failuresof many different types of structures, but is now supplemented withnew case studies to illustrate the dynamics of failure in actiontoday. Jacob Feld knew thirty years ago that in order to learn from ourmistakes, we must first acknowledge and understand them. With thisrevised volume, Kenneth Carper has ensured that Feld'snow-posthumous message will continue to be heard for years tocome. Jacob Feld's comprehensive work on failure analysis has now beenskillfully amended to address current design and constructiontools, materials, and practices. Building on the first edition'speerless examination of the causes and lessons of failure,Construction Failure, Second Edition provides you with expandedcoverage of: * Technical, procedural, structural, and nonstructural failures * Natural hazards, earthworks, soil and foundation problems, andmore * Reinforced, precast and prestressed concrete, steel, timber,masonry, and other materials * Responsibility and litigation concerns, dispute avoidance, andalternative dispute resolution techniques * Construction safety issues * Many different types of structures, including dams andbridges Construction Failure has as much to teach us today as it did thirtyyears ago. This revised volume is an essential resource for designengineers, architects, construction managers, lawyers, and studentsin all of these fields.

Serviceability failures of concrete structures involving excessive cracking or deflection are relatively common, even in structures that comply with code requirements. This is often as a result of a failure to adequately account for the time-dependent deformations of concrete in the design of the structure. The serviceability provisions embodied in codes of practice are relatively crude and, in some situations, unreliable and do not adequately model the in-service behaviour of structures. In particular, they fail to adequately account for the effects of creep and shrinkage of the concrete. Design for serviceability is complicated by the non-linear and inelastic behaviour of concrete at service loads. Providing detailed information, this book helps engineers to rationally predict the time-varying deformation of concrete structures under typical in-service conditions. It gives analytical methods to help anticipate time-dependent cracking, the gradual change in tension stiffening with time, creep induced deformations and the load independent strains caused by shrinkage and temperature changes. The calculation procedures are illustrated with many worked examples. A vital guide for practising engineers and advanced students of structural engineering on the design of concrete structures for serviceability and provides a penetrating insight into the time-dependent behaviour of reinforced and prestressed concrete structures.
