"Guidelines for the classification and management of risk, for the evaluation of safety and for the monitoring of existing bridges". An automatic calculation model of the seismic attention class optimized for the use of cloud computing services

The Italian road network is complex due to the particular orography of the territories crossed, often characterized by areas of high seismicity. In addition, bridges and viaducts present a peculiar state of decay mainly due to their remote period of construction. The situational picture is also difficult to understand due to the absence or non-uniformity of infrastructural safety management systems (SMS). To fill this gap, the Italian Higher Council of Public Works has issued guidelines for risk management, that allow the classification, safety assessment and monitoring of existing bridges. The central focus of the new approach is the identification of the overall attention class, which allows to move from assessments on a territorial scale to safety assessments on a limited number of bridges. This work focuses on the development of a prototype for the automatic calculation of the seismic attention class that has been optimized for cloud computing services. In particular, a standardized procedure has been defined that guides the operator in the evaluation of the seismic attention class. The model also allows to carry out the validation of other software. Finally, the prototype created is easily extensible to other attention classes which are therefore manageable independently in the perspective of modular development of an open access and open source platform.
