We were outside Austria at the beginning of the week and carried out load tests with heavy vehicles on a bridge. The bridges are loaded on the one hand by crossing at different speeds, but also with full braking on the respective bridge segments. The forces involved are imposing!
We use our autarkic monitoring system to measure paths at neuralgic positions. We use a dynamic measurement mode to ensure that the effects of the dynamic excitations are recorded accurately. This also allows us to measure the dynamic effects of overruns and braking precisely. The load tests were completed at the beginning of the week, but we are continuing to measure for another week during operation.
During the first night, we were already able to determine that higher dynamic effects occurred during regular operation than during the load test series. For an optimal assessment and the calculation of critical limit values, we measure for one week in dynamic measurement mode. We then switch over remotely and monitor the bridge over the next few years. If critical limit values are reached, our monitoring system informs or warns automatically.
By the way, a wired power and data connection on-site is not necessary. This reduces installation costs and increases flexibility and options enormously.
Here is a short video of the load tests:
