TitleVibration-based Structural Health Monitoring
Project id.78
Reference sectorSMART CITY
IP Protection LevelNo patent is pending. However, the core software for the development of monitoring systems is included in the Special Public List of Software issued by the Italian Society of Authors and Editors.
Description of the innovation projectThe developed monitoring system automatically processes vibration measurements to remotely detect damage in civil structures. This information can support the shifting from the current reactive (we replace a component after it is damaged) and scheduled (we replace structural components at regular time intervals independently of their conditions) strategies to innovative proactive maintenance approaches based on the effective conditions of the structure. Monitoring systems makes timely damage detection possible, with the consequent money and life savings and reduction of downtime. Advanced data processing procedures are integrated with programmable hardware to make costs affordable.
State of dev.Prototype
Industrial applicationThe developed monitoring system is devoted to the analysis of health state and performance of civil engineering structures. It is based on vibration measurements and, by automatically extracting the modal properties of the structure, it is able to remotely detect damage, for instance after hazardous events such as earthquakes, floods. Moreover, it is able to evaluate the vibration level that can cause discomfort for the occupants or cosmetic damage to the structure.
Market segmentMarket segment includes construction companies and public institutions having in charge maintenance of civil structures. The dimension of the market segment is dictated by the presence of a large stock of structures at the end of their lifespan and in need of extension, of historical structures, and of strategic structures exposed at risk.
Advantage factorThe main competitive advantage is related to the availability of an original procedure for modal parameter monitoring developed and extensively validated in an academic context. This is one of the first attempts of technology transfer for this type of technology from academy to industry.
Commercial challengeThe proposed technology for Structural Health Monitoring system is in its prototype stage, but it has already been validated against real data, for instance by some shaking table tests. Thus, the company aims at exploiting the competitive advantage related to the availability of a proprietary technology developed in an academic framework by starting its commercialization.
