Tekst

Extensive monitoring and measuring systems have been installed at different bridges and railways around Norway, with the main goal of generating data that can be used to develop the technology utilized for design of these structures. These systems are funded by the Norwegian Public Roads Administration, the Norwegian National Rail Administration and the Norwegian University of Science and Technology (NTNU).

Monitoring systems have been installed at the Bergsøysund, Hardanger and Gjemnessund bridges. The structures are monitored 24 hours a day, every day of the year. This makes it possible to capture the dynamic behaviour, caused by aerodynamic and hydrodynamic forces as well as traffic, both during extreme weather conditions such as storms and under normal operating conditions.

The railway measuring systems are generally used over a shorter period of time, from a few days up to several months. The main reason why these systems are not monitoring all year is due to higher predictability of the load from the passing trains, considering that the train schedule is fairly equal and permanent all year round.
