Abstract:
With advances in sensor technology and availability of low cost integrated circuits, a wireless monitoring
sensor network has been considered to be the new generation technology for structural health monitoring. Wireless
Intelligent Sensor and Actuator Network (WISAN) has hence been developed as a vibration based structural
monitoring network that allows extraction of mode shapes from output-only vibration data from a structure. The
mode shape information can further be used in modal methods of damage detection. This network has been tested on
a pre-stressed concrete bridge in Kuala Lumpur, Malaysia. The results have been compared with a similar sized steel
girder bridge.
