The practical structural health monitoring system is suggested aiming to detect certainly the occurrence of damage and to identify the portion with the degree of damage. Our system is highly reliable and simple of low cost adopting new sensors which translate the measurements to the damage indices and transmit in the minimum amount of data. The developed smart AE (acoustic emission) sensor is useful for local monitoring detecting the crack of concrete, and new smart VA (vibration analyzing) sensor is used for global monitoring by arresting the change in dynamic properties of the building structure. The wireless network using the standard ZigBee provides with the reduced consumption of electricity, and is expected to realize multi-hop transmission and mutual communication of sensors in the near future.
