This book was released on 2000 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: For years, resistance based strain sensors have been used for the measurement of strain. The resistance-type strain gage provides a very reliable and accurate measurement of strain, but as with any instrument it has its limitations. Extrinsic Fabry-Perot Interferometric (EFPI) fiber-optic strain sensors are now commercially available from several manufacturers. Fiber-optic strain gages have stated advantages over resistance based strain gages, including immunity to electromagnetic interference (EMI) and leakage to ground. This paper presents a limited performance comparison between the (Fabry-Perot type) fiber-optic strain gage and the traditional resistance strain gage. The evaluation was limited to load testing at room temperature and apparent strain characterization cryogenically and at elevated temperatures.

Book excerpt: A comprehensive introduction to strain-based structural health monitoring of civil structures, with focus on measurement and data analysis Introduction to Strain-Based Structural Health Monitoring of Civil Structures focuses on the SHM of civil structures and infrastructure, and develops the relevant topics of measurement and data analysis from a fundamental to advanced level. The book contains an overview of the available and emerging strain monitoring technologies like traditional strain-gauges and vibrating wire sensors, discrete and distributed fiber optic sensors, and large area electronics. The fundamentals of error analysis, as well as typical sources of errors in measurements, are discussed. Sources of strain in typical construction materials such concrete, steel, timber, and composite materials are also discussed, while both basic and advanced data interpretation and analysis for monitoring of concrete and steel structures are presented in detail. Methods applicable to a large spectrum of beam-like structural elements and civil structures, such as bridges, buildings, and pipelines, are summarized. These methods are developed at three scales: local scale (material or structural), global (structural) scale, and integrity scale, and are illustrated with practical examples. Key features: Defines and describes SHM and identifies its main components and stakeholders. Explores the potential and benefits as well as the limitations of SHM. Introduces strain-based structural health monitoring of civil structures, with focus on measurement and data analysis. Covers the physical principles, advantages, and limitations of various types of sensors. Covers fundamental error analysis and presents typical sources of errors. Covers the sources of short- and long-term strain, and how to interpret the strain measurement. Includes basic and advanced model-based methods for data analysis. Contains the basic strain-based SHM methods for monitoring various types of structures at local, global, and integrity scale. Suitable as a guide for practicing engineers, a reference for infrastructure owners, and a textbook for researchers and SHM university courses. A valuable companion to Glisic & Inaudi’s Fibre Optic Methods for Structural Health Monitoring. Introduction to Strain-Based Structural Health Monitoring of Civil Structures is essential, state-of-the-art reading for civil and structural engineers and professionals in SHM, as well as teachers, researchers, and students in civil engineering.
Download or read book Structural Monitoring with Fiber Optic Technology written by Raymond M. Measures and published by Academic Press. This book was released on 2001 with total page 738 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first to address the field of structurally integrated fiber optic sensors. Fiber optic sensors embedded within materials and systems are able to measure a variety of parameters (i.e. temperature, vibration, deformation, strain, etc.) that allows for real time non-destructive evaluation. Examples include the following: monitoring structural fatigue in aging aircraft or loads in bridge structures. In more advanced applications, fiber optic sensors control actuators that allow materials to adapt to their environment. This gives rise to the names, "smart," "intelligent," and/or "adaptive" materials or structures. Structural Monitoring with Fiber Optic Technology is the firs single author book on the new field of fiber optic structural sensing. As such it provides: coverage of the fundamentals of the technology, a coherent and systematic discussion on the most important aspects of the subject, a broad view of the subject, while retaining a degree of focus on those advances most significant in terms of their future potential, particularly in regard to broad implementation of the technology. The book provides an introduction to the relevant value to structural monitoring. It also highlights the advantages of fiber optic based sensors over conventional electrical measurement technology. The book richly illustrates the subject matter with 615 figures and provides many examples of fiber optic structural sensing, including a detailed overview of a number of major field site applications. Most of these large scale applications are drawn from the civil engineering community as they have been the first to strongly embrace fiber optic structural monitoring. This is especiallytrue for bridges, where innovative new designs and the use of fiber reinforced polymer composite materials to replace steel represents a major advance that is expected to revolutionize the construction industry. Examples include new bridges, which are serving as testbeds for these new materials and are instrumented with arrays of fiber optic structural sensors. In one case, this state-of-the-art monitoring system permits engineers at a distant site to track the response of the bridge to traffic loads and keep an eye on the long term performance of the new materials. Fiber optic structural sensing technology is equally applicable to other industrial sectors, such as the aerospace and marine industries. Indeed, several examples of ships being instrumented with arrays of fiber optic sensors are also included. * The author directed one of the leading laboratories in the development of this technology and its application to civil engineering * Provides a strong, concise foundation in the basics of the technology * Includes many examples of the application of the technology, including many major field site case studies * Richly illustrated with 615 figures, many redrawn to make them easier to understand; also includes over 600 references * Written in a style designed to help the reader unfamiliar with fiber optic technology appreciate what can be accomplished with this new form of structural monitoring
