A Real-Time and Non Intrusive Structural Health Monitoring System for Buildings

Abstract

The constant innovation in the development of sensing devices for detecting health status of buildings, highlights the importance of this professional field. In fact, correct diagnosis would prevent many pathologies, driving maintenance interventions towards timely and well targeted operations. This paper describes the development of a monitoring system prototype, conceived to be very low intrusive, that can be applied also on existing buildings, without any need to predispose chases for power or communication cables. Its adoption is expected to be useful not only for standard health status monitoring of buildings during their lifecycle, but also for automated monitoring of old buildings during the conduction of works for their renovation. As a matter of fact in this case accidents due to unexpected collapses during work execution are very common, hence the static condition of buildings should be continuously checked automatically and alerts sent in case of high risk of failures. The sensors under development have been programmed in such a way to be able to monitor rotations and send alerts in case critical thresholds are overcome.
