Long span suspension bridges cost billions. In recent decades, structural health monitoring systems have been developed to measure the loading environment and responses of these bridges in order to assess serviceability and safety while tracking the symptoms of operational incidents and potential damage. This helps ensure the bridge functions properly during a long service life and guards against catastrophic failure under extreme events. Although these systems have achieved some success, this cutting-edge technology involves many complex topics that present challenges to students, researchers, and engineers alike. Systematically introducing the fundamentals and outlining the advanced technologies for achieving effective long-term monitoring, Structural Health Monitoring of Long-Span Suspension Bridges covers: The design of structural health monitoring systems Finite element modelling and system identification Highway loading monitoring and effects Railway loading monitoring and effects Temperature monitoring and thermal behaviour Wind monitoring and effects Seismic monitoring and effects SHMS-based rating method for long span bridge inspection and maintenance Structural damage detection and test-bed establishment These are applied in a rigorous case study, using more than ten years' worth of data, to the Tsing Ma suspension bridge in Hong Kong to examine their effectiveness in the operational performance of a real bridge. The Tsing Ma bridge is the world's longest suspension bridge to carry both a highway and railway, and is located in one of the world’s most active typhoon regions. Bridging the gap between theory and practice, this is an ideal reference book for students, researchers, and engineering practitioners.

This book presents extensive information on structural health monitoring for suspension bridges. During the past two decades, there have been significant advances in the sensing technologies employed in long-span-bridge health monitoring. However, interpretation of the massive monitoring data involved is still lagging behind. This book establishes a series of measurements for interpretation frameworks that focus on bridge-site environmental conditions, and global and local responses of suspension bridges. Using the proposed frameworks, it subsequently offers new insights into the structural behaviors of long-span suspension bridges. A valuable resource for researchers, scientists and engineers in the field of bridge structural health monitoring, it provides essential information, methods, and practical algorithms that can facilitate in-service bridge performance assessments.

Original research on SHM sensors, quantification strategies, system integration and control for a wide range of engineered materials New applications in robotics, machinery, as well as military aircraft, railroads, highways, bridges, pipelines, stadiums, tunnels, space exploration and energy production Continuing a critical book series on structural health monitoring (SHM), this two-volume set (with full-text searchable CD-ROM) offers, as its subtitle implies, a guide to greater integration and control of SHM systems. Specifically, the volumes contain new research that will enable readers to more efficiently link sensor detection, diagnostics/quantification, overall system functionality, and automated, e.g., robotic, control, thus further closing the loop from inherent signal-based damage detection to responsive real-time maintenance and repair. SHM performance is demonstrated in monitoring the behavior of composites, metals, concrete, polymers and selected nanomaterials in a wide array of surroundings, including harsh environments, under extreme (e.g., seismic) loading and in space. New information on smart sensors and network optimization is enhanced by novel statistical and model-based methods for signal processing and data quantification. A special feature of the book is its explanation of emerging control technologies. Research in these volumes was initially presented in September 2013 at the 9th International Workshop on Structural Health Monitoring (IWSHM), held at Stanford University and sponsored by the Air Force Office of Scientific Research, the Army Research Laboratory, and the Office of Naval Research.

An Insiders’ Guide to Inspecting, Maintaining, and Operating Bridges Suspension bridges are graceful, aesthetic, and iconic structures. Due to their attractiveness and visibility, they are well-known symbols of major cities and countries in the world. They are also essential form of transportation infrastructure built across large bodies of water. Despite being expensive to build, they are economical structures for the lengths they span. They have evolved significantly from the basic concept dating back to 200 BC China through the first design for a bridge resembling a modern suspension bridge, attributed to Fausto Veranzio in 1595, to present day span lengths close to two kilometers. Offers Insight from Bridge Owners across the Globe Many of these bridges carry significant traffic, and their upkeep is very important to maintain transportation mobility. They offer grace and functionality, yet are extremely complex to construct and maintain. Bridge owners spend considerable amount of time and resources to ensure uninterrupted service, safety, and security for users. Inspection, evaluation, maintenance, and rehabilitation have evolved significantly. Modern materials and innovative design and construction practices have been integrated into these bridges to maintain durability and extended service life. Inspection, Evaluation and Maintenance of Suspension Bridges Case Studies gives detailed case studies of the Manhattan, Akashi Kaikyo, Tsing Ma, Storebælt East, Forth Road, Bronx–Whitestone, George Washington, Angus L. Macdonald, Mid-Hudson, Shantou Bay, and Kingston–Port Ewen Bridges. It is written by the owners and practitioners who strive to cost-effectively manage them, and applies all the inspection, evaluation, and rehabilitation methods discussed in the companion volume to give a comprehensive picture of how suspension bridges are managed. It is invaluable to everyone interested not only in suspension bridges but also in the upkeep of any bridges – students, designers, maintenance personnel, contractors, and owners.
