Technology Lecture: Global Trends and Benefits of Structural Health Monitoring for Civil Infrastructure
Date: 04 Mar 2011 - 04 Mar 2011
Venue: SIMTech Auditorium, Level 3, Tower Block
Structural Health Monitoring is a huge international research area as well as an emerging financial opportunity. The term covers a wide range of technologies from sensors to artificial intelligence with commercial applications ranging from static logging and threshold crossing alerts to vast sensors arrays fusing slow and fast-sampled environment, load and response data and feeding directly into operational and strategic decision making. So what technology is available, what can it do for you and where is it heading? The talk addresses these issues with reference to projects operated in North America and Asia where growing and almost impenetrable complexity in comprehensive systems are being pre-designed with a view to life-time management for new ‘super-structures’, particularly cable-supported bridges. Experience in this field shows that simple, well designed, focused and affordable systems have immediate benefits for operational decisions. Hot research topics such as smart sensors and data mining will also be presented.
About the Speaker
James obtained his BSc in Mechanical Engineering at University of Bristol in 1979, then after five years in the industry, he returned to Bristol to do a PhD at the Earthquake Engineering Research Centre (1988) followed by four years as Post Doctoral Researcher. He joined Nanyang Technological University Singapore in 1992 and left for University of Plymouth in 2004. Finally, in March 2005 he joined the University of Sheffield as Professor of Structural Dynamics. He was awarded Doctor of Engineering (DEng) by University of Bristol in 2008. His research and consultancy interests have centred on the dynamic performance of large civil structures, such as long span bridges and tall buildings. He has carried out vibration testing on many full-scale structures, most famously the Humber Bridge and the two suspension bridges over the Bosporus in Istanbul. He has extended these interests to structural health monitoring, a research discipline that encompasses both static and structural response along with simulations, data management, data mining and performance diagnosis.
In addition, he worked on projects involving vibration serviceability of footbridges under pedestrian load and specialist facilities for research, testing and production requiring extreme low levels of vibration. James is a Member of the Institution of Structural Engineers, Fellow of Institution of Mechanical Engineers and (by invitation) a Fellow of the International Society for Structural Health Monitoring of Intelligent Infrastructure (ISHMII). He also contributes to the ASCE Committee on Structural Identification of Constructed Systems. James principal areas of interest within Full Scale Dynamics are vibration testing of bridges, long term monitoring of chimneys and bridge and vibration serviceability assessment of super-low vibration facilities. He is author and co-author of 73 referred international journal papers and 153 conference papers in print on a wide range of topics. As one of three company directors in Full Scale Dynamic Ltd, he is responsible for scientific development, quality assurance and health and safety.
