Condition Monitoring and Structural Health Monitoring of Infrastructure Systems presents important developments in this field whilst focusing on specific areas such as bridges, buildings, industrial facilities, dams and hydraulic structures, pipelines, and power generation/transmission systems, to provide the reader with a focused insight into CM/SHM in these areas. The book provides both details of the technologies and applications with a focus on infrastructure components and systems. Given its specific focus on areas of infrastructure it will help researchers, designers, and practitioners in assessing the current state-of-the-art and in the identification of problems/challenges as well as to provide a focus of the “how to” so that they can get ahead in their research/application. It will assist the researcher, practitioner, and engineer in solving the issues of assessment and design which are critically needed as well as those of diagnosis and prognosis of the condition of a structure/system moving away from the inefficient time-based inspection system to a more efficient condition-based one. Written for a wide variety of audience, this book will cover different technologies, sensors, and analysis methods with a view towards application to ensure that the reader gets an integrated overview and in-depth knowledge of the subject.Focuses on background and application so that the state of the art is clearly useable by the researcher, student, and practicing engineerShows breadth and depth in key areas of structuresDiscusses civil infrastructure over a range of systems

Civil infrastructure systems are generally the most expensive assets in any country, and these systems are deteriorating at an alarming rate. In addition, these systems have a long service life in comparison to most other commercial products. As well, the introduction of intelligent materials and innovative design approaches in these systems is painfully slow due to heavy relianceon traditional construction and maintenance practices, and the conservative nature of design codes. Feedback on the "state of the health" of constructed systems is practically nonexistent. In the quest for lighter, stronger and corrosion-resistant structures, the replacement of ferrous materials by high-strength fibrous ones is being actively pursued in several countries around the world, both with respect to the design of new structures as well as for the rehabilitation and strengthening of existing ones. In North America, active research in the design of new highway bridges is focused on a number of specialty areas, including the replacement of steel reinforcing bars in concrete deck slabs by randomly distributed low-modulus fibers, and the replacement of steel prestressing cables for concrete components by tendons comprising super-strong fibers. Research is also being conducted on using FRPs to repair and strengthen existing structures.

This volume gathers the proceedings of the 3rd International Conference on Resilience, Earthquake Engineering and Structural Health Monitoring (ICONREM), held in Turin, Italy on June 24-28, 2024. The conference fostered new paradigms in the interface of critical infrastructures and the economic and social impact of resilience. The volume covers highly diverse topics, including algorithms for structural health monitoring, bridge dynamics, constitutive modelling under earthquake loading, dynamics of concrete, steel and masonry structures, geotechnical earthquake engineering, optimum design & control in structural dynamics and earthquake engineering, performance-based earthquake engineering, reliability of dynamic systems, repair & retrofit of structures, resilience assessment, seismic isolation, seismic risk and reliability analysis. The contributions, which are published after a rigorous international peer-review process, highlight numerous exciting ideas that will spur novel research directions and foster multidisciplinary collaboration among different specialists.

This book provides information about the application of Structural Health Monitoring technologies to civil engineering structures including buildings, bridges, tunnels, dams, and pavements. The book is unique as it covers application of a broad spectrum of sensors for monitoring of cracks, deformations, loads, and other types of structural anomalies. The range of sensors covered includes conventional as well as novel sensors such as resistance type strain gauges, PZT, magnetic, fiber optics and smart materials. The book describes post earthquake structural health monitoring of historic structures such as masonry towers, real time monitoring of modem cable stayed structures and various construction materials including steel, concrete, and fiber reinforced polymer composites (FRP). It covers distributed and multiplexing schemes for monitoring of large structures, data acquisition and processing as well as techniques for interpretation of data. A specific section is dedicated to issues concerning sensor and instrumentation reliability and durability during sensor placement in harsh construction environment, adverse exposure conditions, and long term performance.
