Researches and implementations of structural health monitoring systems for long span bridges in China

Abstract

This paper presents the recent development in the research and implementation of structural health monitoring systems for long span bridges in China. Following a brief review on the long span bridge projects in recent years and main deterioration and defects problems of existing bridges, the paper puts the focus on the review of the following three aspects: the implementation of structural health monitoring system for long span bridges, the advanced sensing, transmission, and system integration technologies, and the novel signal processing and condition assessment techniques. Finally, the issues on the future research and implementation of structural health monitoring system are discussed.
