| Abstract: |
Rib-to-deck welded connections of orthotropic steel decks(OSD’s) are prone to fatigue problems and the new type of double-side welded connection is applied for optimization. To further reveal transformation mechanism of fatigue mode, the geometrical parameters of double-side welded connection are analysed based on structural stress method. The results show that, compared with other parameters, the thickness of deck brings the greatest impact on the structural stress at the concerned position, but does not change the fatigue failure mode. The fatigue mode of double-side welded connection is related to both internal and external weld size, and the external weld size should be controlled within a certain range relatively. For the basic structure analyzed, when the external weld size is 4mm, 6mm, 8mm and 10mm, the internal weld size shall not be less than 1.5mm, 1.5mm, 3mm and 4.5mm respectively. |
