ABSTRACT
This paper presents a set of undertaken actions for characterizing masonry arch bridges using data structure suitable for proper embedment in Digital Twins and Heritage Building Information Modelling (HBM). Interfaces in bridge maintenance are relentlessly and increasingly sophisticated. For both new and existing bridges, these interfaces are tending towards their ability to deal with different sources of information. Comprehensive digital twins of heritage masonry arch bridges may include several sources of information gathered from the real asset. Measurements can be taken using many different techniques ranging from contact to contactless and from non-destructive to moderately destructive samples. In addition, these twins may base upon different numerical models aimed at predicting and anticipating the present and future behaviors of the asset, respectively. Masonry arch bridges are known for their complex material and structural characteristics. Digitizing these masonry properties is key for effective simulation and analysis, often involving homogenization of diverse material properties. The design of comprehensive information constructs able to store and federate multiple data layers within a single entity is still challenging. Layers must be connected using vast scoped solutions such as knowledge graphs, integrating measurements, simulations and other information sources. In this particular case study on a masonry arch bridge located in Catalonia, Spain, in-situ Non-Destructive Testing (NDT) data is conceptualized for proper infusion within HBIM schemas. This integration pursues a seamless information flow for analysis or predictive purposes.
