| Abstrait: |
The development of automated laser- and laser-hybrid welding has made it possible to fabricate bridges in a new way. Traditional orthotropic decks based on steel-plates with longitudinal trapezoidal stiffeners may experience challenges with fatigue cracks developed at the welds and the edge of cut-out holes. The use of laser- and laser-hybrid can improve fatigue properties in general, but the technology also opens for new designs that improve fatigue properties with use of less material, reduced environmental impact and reduced production costs. A closed multi-box steel panel, also denoted as a steel sandwich element is a promising alternative to conventional orthotropic steel decks. The panels may also replace the concrete slab for traditional composite steel concrete box girder bridges. |
