IoT4SHM - Wireless sensor systems for structural monitoring

The starting point for further developments in IoT4SHM are the technologies developed in the FFG project "PreMainSHM" and the EU project "SensMat", namely a wireless sensor system and, as a special feature, an intelligent software framework that has extensive analysis functions. Thus, analysis and forecasting procedures relevant for condition and risk assessment as well as service life prediction were and are being further developed, adapted and evaluated with the aim of on-site data cleansing and simultaneous data reduction and data fusion. In addition, both data models and analysis tools were prototypically developed and integrated into an interoperable software framework. The latter enables the representation of the state information in the form of a georeferenced digital twin via web user interfaces. Within IoT4SHM, a sustainable and cost-efficient overall solution (modular system) for building monitoring in the form of a wireless incl. cloud-based software framework with tools for data analysis and visualisation, preventive risk assessment, documentation and alerting will be developed to market maturity. End users will have an IoT system at their disposal with which they can not only record and seamlessly document environmental influences in a simple and clear manner, but can also use specific analysis tools for the variety of different damage mechanisms and causes of damage, which enable a simple and plausible condition assessment and damage prognosis of buildings without complex calculations. The applications range from monitoring existing structures (especially bridges) to historical structures. Software interfaces enable the use of the monitoring data or the knowledge gained from it in GIS or BIM-based systems, in tools for structural design or recalculation or in asset maintenance and management systems.
