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.
