| Abstrakt: |
The oldest of a set of 3 steel Vierendeel bridges, carrying railway tracks across the canal from Mechelen to Leuven, shows various cracks, mainly in the vertical members. Material testing demonstrates that the early age steel characteristics show a large variation for strength, yield point, impact notch energy and chemical composition. A thorough investigation into both the ULS and the fatigue resistance does not imply these to be the cause of the cracks. Comparing the location of the cracks and those of the dynamiting and subsequent repair of the steel structure, reveals that the brittleness of the material must be the cause of the damage. |
