Proceeding of the Joint International Symposium on Deformatuon Monitoring. 2-4 November, 2011. Hong Kong. China. Report. Bridges are important transport nodes and play a vital role in socio-economic development across Europe and worldwide. The investments for constructing major bridges are enormous and the associated inspection and maintenance costs can also be very significant. Bridges must survive attacks of high speed winds, earthquakes and current scouring. Aging and increasing traffic are other factors affecting bridges serviceability. The University of Nottingham was one of the very few institutions initiated GPS bridge monitoring in the mid 1990s. This paper overviews the past research and development that were carried out by the University of Nottingham on almost all the major bridges in the UK. This paper also in-troduces a latest Structural Health Monitoring System (SHMS) that is based on real-time high-precision GNSS positioning and taking the maximum benefits offered by the European EGNOS and Galileo Sys-tems. The main contents include these following aspects: 1). design and implementation of the SHMS using existing GNSS equipments, integrated with appropriate terrestrial sensor systems and communications to relay data (network RTK corrections) and alerts to the control centres that are remote from a bridge site; 2). new implementation algorithms to take advantage of the performance benefits by using new European GNSS transmissions (EGNOS, Galileo) to enhance accuracy, quality (integrity), availability, and robustness.
