7 April 2009Wireless sensing system for bridge condition assessment and health monitoring
Discussed in this paper is the deployment of a universal and low-cost dense wireless sensor system for structural
monitoring, load rating and condition assessment of bridges. The wireless sensor system developed is designed
specifically for diagnostic bridge monitoring, providing independent conditioning for both accelerometers and strain
transducers in addition to high-rate wireless data transmission. The system was field deployed on a three span simply
supported bridge superstructure, where strain and acceleration measurements were obtained simultaneously and in realtime
at critical locations under several loading conditions, providing reliable quantitative information as to the actual
performance level of the bridge. Monitoring was also conducted as the bridge was subjected to various controlled
damage scenarios on the final day of testing. Select cases of detected damage using strain and modal based analysis are
presented.
