Remote Structural Health Monitoring of Civil Infrastructures - Recent Trends

摘要

Construction and maintenance of large civil infrastructures are very much essential for development of any country. The modern constructed facilities involve a huge capital cost and complex design procedures to ensure longer service life and better performance in adverse environmental conditions. There is a growing demand to monitor the health of these structures to increase its safety and serviceability. Remote health monitoring (RHM) is a recent methodology, whereby the instrumented structure is continuously monitored from a distant place, using the latest communication and IT tools. Here, multiple structures, located at different places can be monitored from a single station and the response from the structure can be acquired even in adverse situations like flood, cyclone etc., In remote health monitoring, in addition to the provision of continuous monitoring and warning during abnormal behavior, efficient damage detection and performance evaluation algorithms can be integrated with the system. This paper briefly discusses about the various aspects of remote health monitoring techniques, the latest developments in software and hardware associated with RHM, and a short note on the development of a RHM system at Structural Engineering Research Centre, Chennai.
