Hell Bridge test arena

The Hell bridge is an open deck riveted pony Parker truss bridge with 5 identical 35m spans which was completed in 1902. The bridge lies 30km north of Trondheim on the line Nordlandsbanen. The exact design of the bridge may be unique, but it shares many structural details with other bridges in both in the Norwegian and the European railway infrastructure. In fact, the majority of the 1000 steel bridges constructed before 1960 in Norway has the open deck riveted details similar to the Hell railway bridge.

The Hell bridge was taken out of traffic in 2016 and replaced by a modern double track ballasted bridge to meet increasing operational requirements, but the old Hell bridge has not completed its service just yet. One of the 35m spans has been moved to new foundations on land to serve as a test arena for researchers and developers working on condition monitoring, inspection and service life estimation. New sensor technology, monitoring algorithms and damage features can be tested on a real civil engineering structure. 

Since the structure is not in service, structural damage can be introduced by removing structural details, such as rivets, steel profiles and components. This also means that researchers gain access to a real structure without going through rigorous safety training and restricted acces to the infrastructure. The research project is funded by Bane NOR, and will involve researchers, PhD candidates and students at both NTNU and SINTEF.

The test arena at Hell is the ideal venue to bring new sensor hardware, monitoring and inspection technology from the desktop and laboratory into real world applications.
