ABSTRACT
 
Structural health monitoring has been accepted as a justified effort for long-span bridges which are critical to a region’s economic vitality. In Hong Kong, a structural health monitoring system has been devised and implemented for the three long span cable-supported bridges leading to the Hong Kong Airport. The three bridges, namely, the Tsing Ma Bridge, the Kap Shui Mun Bridge and the Ting Kau Bridge, could be considered as the most heavily instrumented bridge project in the world. The system is known as WASHMS: the Wind And Structural Health Monitoring System, in which a total of about 774 sensors were permanently installed. The system has been operated for nearly ten years and a common concerned problem is how to take full advantage of the real-time monitoring data for effective and reliable health assessment of the structures. The WASHMS for the three bridges will be described first in the seminar, and then a methodology and strategy for fatigue damage assessment and life prediction of bridge-deck sections of the Tsing Ma Bridge will be introduced as an example of practical application of the online structural health monitoring data acquired. Some recent trends in the structural health monitoring will also be discussed.

Prof Tommy H.T. Chan graduated with first class honours in Civil Engineering from the University of Queensland in 1984 and gained his doctorate from the same university in 1988. He joined the Hong Kong Polytechnic University in 1991, after working some time with a consulting firm, Maunsell Consultant Asia Limited, and moved to Australia in 2007. Prof Chan is now an Associate Professor (Reader) in Structural Engineering in the School of Urban Development at QUT. Prof Chan has been actively involved in carrying out research on bridges. He has published more than 170 technical papers and over 15 years of experience in structural health monitoring (SHM) of various significant long span bridges in Hong Kong and the mainland China. He is the founding chair and the President of ANSHM (the Australian Network of Structural Health Monitoring). Besides SHM, his research interests include bridge engineering, structural dynamics, Moving Force Identification and Weigh-in-Motion Studies.
