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.

Bridges are subject to daily and seasonal temperature fluctuations. The temperature variations can affect bridge materials and structural integrity, often interacting with other loads and masking their effects. Understanding temperature behaviors is crucial for accurate load assessment and bridge performance evaluation.This book comprehensively studies temperature behaviors of bridges, covering beam, arch, cable‑stayed, and suspension bridges using analytical, numerical, and field monitoring approaches. For each type of bridge, it not only reports field monitoring results but also presents an integrated heat‑transfer and structural analysis framework, significantly enhancing the efficiency of simulating bridge temperature behaviors. Moreover, this book derives simple and general analytical formulas for temperature‑induced deformations of bridges that can be easily adopted by engineers. This standout feature has not been previously studied and reported within academic and engineering societies.A unique feature of this book is the presentation of 25‑year field monitoring data of the Tsing Ma Suspension Bridge, the most extensive field data available, showing the long‑term behavior of the bridge. This invaluable data demonstrates the effects of global warming on infrastructure and necessitates the review of current design codes in the context of climate change. Other typical bridges, including the Hong Kong‑Zhuhai‑Macao Bridge and the Hong Kong Polytechnic University Footbridge, are also used as examples to enhance understanding.Temperature Behavior of Bridges is an essential resource for postgraduate students, researchers, and engineers seeking to master the temperature behaviors affecting modern bridge infrastructure.

This book investigates the substructuring technology in structural health monitoring (SHM) to improve the accuracy and efficiency of the present SHM methods. SHM has been developed for monitoring, evaluation, and maintenance of civil structures. As the civil structures are usually large scale and a large number of sensors are deployed on a structure, accurate evaluation and maintenance of civil structures are always time-consuming. The book establishes a fundamental framework of substructuring method for the fast analysis of finite element (FE) model and monitoring data. Several practical civil structures are used for illustration. The book is intended for undergraduate and graduate students who are interested in SHM technology, researchers investigating the accurate, efficient, and effective methods in SHM field, and engineers working on evaluation and maintenance of civil structures or other structural dynamics applications.
