CSIR-SERC begins monitoring health of Chennai Metro Rail’s composite girder span in corridor 4

CSIR– Structural Engineering Research Center (SERC) has deployed a state-of-the-art, real-time structural health monitoring system for a crucial steel composite girder span in Chennai Metro Rail’s phase II project stretch near Poonamallee Bypass. 

“A total of 15 trigger sensors has been installed on the span to continuously record structural responses or deflections or in common man’s parlance, bending of the track, each time a train passes. We have developed a dedicated, secure, web-based real-time monitoring portal at the Structural Health Monitoring Laboratory (SHML) of CSIR-SERC,” said a scientist involved in the monitoring. Over the last 14 days, the deflections have been within prescribed limits.
