Structures Strengthened with Bonded Composites presents a comprehensive resource on the strengthening of concrete, reinforced and prestressed concrete, masonry, steel and other composite structures using externally-bonded FRP composites. The book emphasizes a systematic and fundamental investigation on bonding and debonding behavior of the FRP-concrete interface and structural performances of FRP-strengthened structures with a combination of experimental, theoretical and numerical studies. This book will appeal to all those concerned with strengthening and retrofitting of existing structures from the effect of additional anticipated loads in the civil sector.

Discusses the FRP strengthening of different types of structures, including bridges, tunnels, buildings, historic structures and underwater constructions Establishes a systematic theory on interfacial fracture mechanics and clarifies different debonding mechanisms Describes design methods and makes comparison of design considerations and methods among different countries Presents temperature and fatigue effects and long-term behavior for different strengthening methods

With rapid urbanization in developing countries and the emergence of smart systems and integrated intelligent devices, the new generation of infrastructure will be smarter and more efficient. However, due to natural and anthropomorphic hazards, as well as the adverse impact of climate change, civil infrastructure systems are increasingly vulnerable. Therefore, future-proofing and designing resilience into infrastructure is one of the biggest challenges facing the industry and governments in all developing and industrialized societies. This book provides a comprehensive overview of infrastructure resiliency, new developments in this emerging field and its scopes, including ecology and sustainability, and the challenges involved in building more resilient civil infrastructure systems.

Structural Health Monitoring and Integrity Management is a collection of the papers presented at the 2nd International Conference of Structural Health Monitoring and Integrity Management (ICSHMIM2014, Nanjing, China, 24-26 September 2014), and addresses the most recent developments in the field of Structural Health Monitoring (SHM) and integrity management from around the world. It is also generally acknowledged that a clear advantage of SHM-technology over traditional NDT methods is the closer interaction and automation of sensing, diagnostics, prognostics and condition-based maintenance that SHM enables. As SHM is a system-level approach which integrates sensors/actuators networks with structures, software to interpret sensor signals, and hardware to process and manage the signals, its maturity based on the complexity and targeted solutions can be classified into four different sequential levels: detection, identification, quantification, and decision. Detection is the lowest maturity level that the technology can achieve. Once detection is confirmed with a highdegree of confidence, identification of the occurrence of the event in time and space domain is critical, which then can potentially lead to the quantification of the event. A more accurate quantification may lead to a better decision, which provides a much more efficient management solution for the structures than traditional inspection techniques, leading to a system platform for autonomous or intelligent structures.Structural Health Monitoring and Integrity Management will be invaluable to academics and professionals interested in applications encompassing traditional aerospace structures and civil infrastructures, in special equipment and marine/offshore structures, as well as in a variety of other structures and platforms.

Over the past two decades, extensive research has been conducted on the application of fiber-optic sensors (FOSs) in structural health monitoring (SHM). In Volume 1 of this book a long-gauge sensing technique for incorporating a proposed areawise sensing, developed by the authors, was introduced. High precision and good durability of the long-gauge sensors were also demonstrated via technical improvements that further enable the applications of optical fiber sensors and carbon fiber sensors. In Volume 2, based on the merits of the long-gauge sensors, the methods that have been developed for processing areawise distributed monitoring data for structural identification are introduced. A discussion follows on how those methods are capable of performing a rich recognition of local and global structural parameters including structural deflections, dynamic characteristics, damages, and loads. Also presented is a three-level method of structural performance evaluation that utilizes monitoring data and identified results.

Structural health monitoring (SHM) can be characterized as the integration of sensing and intelligence to enable the potential damage to be monitored, analyzed, localized, and predicted in real time and in a nondestructive manner. Over the past two decades, extensive research has demonstrated that fiber-optic sensors (FOSs) are well suited for SHM sensing requirements in infrastructure systems. In this book, a brief overview of SHM and the application of FOS are presented. The book focuses on advanced techniques that utilize fiber-optic long-gauge sensing and overcome the limitations of traditional sensing and fulfill the requirements of infrastructure systems. The long-gauge FOSs have the merit of revealing both micro- and macrolevel information. Subsequently, a new approach, areawise distributed monitoring, is thoroughly discussed and its superior performance in SHM demonstrated. Finally, the application of areawise distributed monitoring, combined with the aforementioned long-gauge sensing technique, is presented for groups and networks of complex infrastructure systems.
