The Deutsche Bahn draws up recalculations at different levels for their railway bridges. New evaluations on complex bridge constructions must be carried out with the assistance of measurement technology.
This new evaluation can be implemented with short-duration measurements – so-called system measurements. They are however extremely complex and only provide a time-limited glimpse of the real loads.
Permanent monitoring solutions offer an alternative to short duration measurements. They show the behavior of the bridge over a longer period of time and provide information about the resulting load collective which includes not only the traffic loads, but also wind forces, temperature changes and other influences. This allows changes to the bridge to be detected in time and so avoid accidents.
