Ponti antichi e moderni: utilizzo di tecniche geomatiche per il rilievo, la rappresentazione e la modellazione strutturale
In the last few years, at the SmartLab laboratory of the University of Calabria, there were developed activities in the field of surveying, monitoring and representation of structures. In the framework of these activities, Geomatics techniques for the surveying of bridges are widely used since 2014. The results of the measurements are used for documentation and representation purposes, as well as for the reconstruction of the constructive procedures. The finite element modeling of the structures has been obtained to simulate their behavior in case of earthquake. The article describes the activities relating to two bridges, that have very different characteristics. The first bridge has been recently built, and it is characterized by a superstructure realized with precast prestressed concrete girders and provided with seismic isolators. In this case, the activity is mainly aimed to get an "as built", useful for control and documentation. The second bridge dates back to the 50s of the twentieth century: it is an arch bridge made of reinforced concrete. The surveying in this case is aimed to the exact reconstruction of geometry, the identification of foundation settlement and the finite element modeling, to simulate the behavior of the structure in seismic conditions. The article describes the activities, instruments and techniques used for surveying and modeling operations, along with the deviations between models and "as built".
