The condition of a structure – similar to that of people – is characterised by an ever more rapid degradation as it ages. Preventive measures against ageing are all the more successful the earlier they are taken. This Priority Programme “Hundred plus” aims to extend the service life of complex structures through intelligent digitalisation. Three core research areas are launched in the proposal for the entire program: (1) digital models, (2) digital linkage, and (3) condition indicators. Digital models and digital linkage are the focuses of funding period 1. The successful development of methods in the SPP is supported by two essential elements. The first element is the central coordination of the activities, the promotion of a mutual, fruitful exchange of knowledge and experience as well as comprehensively coordinated support for young scientists. Various activities are planned for this purpose, e.g. organisation and implementation of annual key meetings of all researchers in the SPP, interdisciplinary cluster workshops, events for doctoral training and the involvement of guests and associates. Specific public relations work will promote the visibility of the SPP.The second element is the research on the validation structure within the scope of an accompanying scientific project. The aim is to test and validate the methods, which are developed in this SPP, regarding model generation, digital linking and the derivation of condition indicators on a real demonstrator structure. The Weserstrombrücke (Weser River Bridge), which is an overpass of the BAB A2 over the Weser near Bad Oeynhausen, has been selected as the validation structure. In funding phase 1, digital models will be created, tested and improved using various resources such as existing plans, laser scans and photogrammetry measurements as well as non-destructive methods. The results form the basis for a digital twin. This and all other data will be stored, processed and sustainably saved on the platform, which is to be concurrently set up, for data management and exchange. Besides, an initial structural health monitoring system for the validation object is to be developed and installed. This will create a real data basis. In addition, all these heterogeneous models and data, which come from different sources, will be linked together. This whole system can be used to realise a comprehensive scientific exchange across all research projects in phase 1. Furthermore, sub-projects can be developed in phase 2 on the basis of this existing system.
