Load Monitoring of Highway Bridges

The chair of steel and steel hydraulic structures won the public tender for the project “Load-Monitoring” from Toll Collect GmbH and Autobahn des Bundes GmbH and has successfully completed the project. As part of the project the Lehrstuhl developed a concept based on Bridge-Weigh-In-Motion (B-WIM) systems and toll data, which can efficiently determine the axle loads of vehicles on the roading infrastructure and bridges of the german highway system.

B-WIM systems enable a comparatively cheap method of measuring axle loads by using a small number of sensors mounted to the underside of bridges measure their deformation as vehicles drive over them. However, a regular calibration of these systems is required to ensure accurate results. With the help of the toll data collected by Toll Collect GmbH trucks travelling on the highway can be used to automatically and continually calibrate the system. The feasibility of this concept was tested using publicly available data and our own test data from a load test on a highway in the Hamburg area. Additionally a Dashboard-Mockup was developed, which shows the current and historical loading on the bridges of the german highway system. The results of the project were presented in the project report and in a presentation at the IAA Conference in Hannover.
