Digital twins of bridges: notions towards a practical digital twinning framework

Digital twins, the virtual counterparts of objects throughout their life cycle, are a crucial component of ongoing digitization. While the civil engineering community has already recognized the advantages of utilizing digital twinning, there is still a lack of comprehensive research in the field, resulting in uncertainties. This article proposes a set of notions regarding digital twins of bridges - structures of logistic and strategic importance and high demands of resilience. By stating the principles for comprehensive digital twinning, the notions can guide practical applications of digital twins of bridges and other civil engineering facilities.
