Description of your role
In our regions, bridges are becoming increasingly older, being in parallel confronted nowadays to an increasing traffic level as well as to a constant increase of the proportion of heavy trucks. Therefore, the condition assessment of bridge structures is particularly important. The present research work aims to develop further an efficient new method for condition assessment called the Deformation Area Difference (DAD) Method and to combine it with modern digital methods such as photogrammetry and drones. This new method represents a powerful alternative to visual inspection and long-term monitoring by simplifying and automatizing the process.
The proposed DAD-Method is based on conventional static load deflection tests. It allows the localization of stiffness-reducing damage on a bridge structure by using a very precise measurement of its deflection line and by combining this outcome to a deflection line generated by a simplified finite element model of the bridge. In order to investigate the condition of a bridge by the DAD-Method modern measurement techniques such as photogrammetry and laser scanning are used. In the framework of the conducted research, these techniques are also compared to traditional measurement systems such as total station and inductive displacement sensors as well as to digital levelling sensors. By theoretical examples and experimental laboratory tests as well as in situ bridge tests, the method has already proven to be able to detect and localize damage when the damage level is dominating measurement noise. The output of this research can be found in literature.
In the new PhD research work, the method will be further developed by using autonomous flying drone.
The project is realized in collaboration with the Luxembourgish Bridge and Road Administration Ponts & Chaussées Luxembourg.
