Health Assessment of Engineered Structures has become one of the most active research areas and has attracted multi-disciplinary interest. Since available financial recourses are very limited, extending the lifespan of existing bridges, buildings and other infrastructures has become a major challenge to the engineering profession world-wide. Some of its related areas are only in their development phase. As the study of structural health assessment matures, more new areas are being identified to complement the concept.
This book covers some of the most recent developments (theoretical and experimental) and application potentials in structural health assessment. It is designed to present currently available information in an organised form to interested parties who are not experts in the subject.
Each chapter is authored by the most active scholar(s) in the area. After discussing the general concept, various currently available methods of structural health assessment (such as the use of smart sensors) are presented. Health Assessment discusses the following: sensor types, platforms and data conditioning for practical applications; wireless collection of sensor data, sensor power needs and on-site energy harvesting; and long term monitoring of structures. Uncertainty in collected data is also extensively addressed. A chapter discussing future directions in structural health assessment is also included.

Author: Peter C. Taylor | Size: 12.8 MB | Format:PDF | Quality:Original preprint | Publisher: CRC Press | Year: 2013 | pages: 214 | ISBN: 9780203866139
Features
Explains the benefits of curing on concrete performance
Offers guidance on how to select and apply a curing method
Discusses how to specify and measure curing in a project
Includes examples evaluating the use of curing in real-world structures
Discusses U.S. and European Standard specifications, making the book applicable for international use

Summary
Curing is one of those activities that every civil engineer and construction worker has heard of, but in reality does not worry about much. In practice, curing is often low on the list of priorities on the construction site, particularly when budgets and timelines are under pressure. Yet the increasing demands being placed on concrete mixtures also mean that they are less forgiving than in the past. Therefore, any activity that will help improve hydration and so performance, while reducing the risk of cracking, is becoming more important. Curing Concrete explains exactly why curing is so important and shows you how to best do it.
The book covers:
The fundamentals behind hydration
How curing affects the properties of concrete, improving its long-term performance
What curing technologies and techniques you can use for different applications
How to effectively specify, provide, and measure curing in a project
The author also gives numerous examples of how curing—or a lack of it—has affected concrete performance in real-world situations. These include examples from hot and cold climates, as well as examples related to high-performance concrete, performance parameters, and specifications and testing. Written for construction professionals who want to ensure the quality and longevity of their concrete structures, this book demonstrates that curing is well worth the effort and cost.

Corrosion is generally described as "an attack on a metallic material by reaction with it’s environment". The corrosion of metallic materials causes large economic losses and is a high risk for accidents. The cost of corrosion is great but it is possible to reduce this cost by a better employment of existing knowledge. Providing a thorough contribution to knowledge distribution, Bardal combines a description of practical corrosion processes and problems with a theoretical explanation of the various types and forms of corrosion, with particular attention to the interaction between description and theory. A well thought-out introduction to corrosion science, with excellent examples and useful tables of data. Exremley well illustrated with 167 diagrams and photographs. Contains extensive reference material utilising the latest international standards. Vital emphasis is placed on the connections between practical problems and basic scientific principles.
