ABSTRACT
In the coming years, bridge maintenance will be an essential task for the upkeep of the infrastructure. Especially in the case of bridges with small and medium spans in the municipal road network, in many cases there are no longer sufficient personnel available for the inspection and maintenance of structures. Therefore, it will be necessary in the future to develop concepts for a partially automated bridge inspection. If information is available from the actions and resistances of structures, the measured values contain important information on the condition of the structure. One concept for this can be digital twins. Based on digital twins and the information they contain; intelligent maintenance management can be implemented. In this paper, we present the challenges and chances of implementing the digital twin concept on a single-span prestressed concrete frame bridge.
