The rapid improvement in telemetry and computer technology is literally driving a revolution in earthquake engineering and, in particular, in the monitoring of civil built infrastructures. Monitoring buildings in earthquake-prone areas is a task of major importance both to ensure their structural integrity and to obtain an insight into their responses in the event of an earthquake in order to mitigate urban earthquake risk by new, effective seismic design provisions.
This revolution started in the late 1990s (Straser and Kiremidjian 1998), when the earliest applications of wireless communication technology were connected together with embedded pc and sensors for structural monitoring purposes. These earlier applications first showed that real-time processing of data can be performed locally and that wireless monitoring systems are feasible, reliable and cost-effective. Over the last few years, prototype structural wireless monitoring systems have been validated by tests performed on...
