Abstract

Recent catastrophic failures of civil engineering infrastructures have drawn attention on the need to better manage these complex engineered systems to ensure their safe use by the society. Structural health monitoring (SHM) has emerged over the past decade as an active, interdisciplinary research field dealing with the development of sensing technologies and data processing methods aimed to perform condition assessment and damage detection of structural systems. Though many advances have been made over that period, measuring displacements from civil structures is often challenging and costly with the conventional structural health monitoring applications. To overcome the drawbacks due to the wired solutions and the use of expensive equipment, alternative methods were recently developed. This thesis comes with two main innovative aspects. The advancement of wireless sensors to reduce the cost of monitoring systems is at the core of the dissertation. After that, the author activity addresses the need to transmit the information also in emergency situation, by satellites, to the location where the collected data are supposed to be processed. The proposed system is validated, showing control mechanism and laboratory tests, in order to provide a reliable way that may be adopted in the real-time structural health monitoring and managed by remote control.
