The term Structural Health Monitoring (SHM) describes the use of one or more in-situ sensing systems placed in or around a structure, with the aim of providing real time evaluation of its performance and ultimately preventing structural failure. Although most commonly used in civil engineering (roads, bridges, dams, etc), SHM is finding application in other engineering environments (i.e. aerospace). This book will present the first comprehensive coverage of SHM.The book begins with a review of the various types of sensors currently used in SHM, including point sensors (traditional strain gauges and more recently developed optical fibre sensors) and non-contact systems (visual / photographic inspection, remote sensing, NDE techniques). The bulk of the text (chapters 4-7) describes the processing and interpretation of data from a number of sensors working in parallel. Chapters 8 and 9 consider issues related to the structures themselves. Chapter 10 looks at the design of a 'tailor made' SHM system, and the final chapter considers some specific case studies.
