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 and 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, the 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 the 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.
