Corrosion and fatigue are two main factors to determine the durability of steel bridges. In this research, first, in order to investigate the time-dependent corrosion characteristics of the uncoated out-of-plane gusset welded joints, accelerated exposure tests were carried out for a period of five months to fifteen months. The corrosive environmental condition was S6-cycle specified in JIS for painted steel. Fatigue tests were also performed on the weld joints before and after the corrosion tests. It was found that the corroded joints had similar or larger toe radius than the uncorroded ones. The fatigue cracks for the corroded joints initiated from the fillet weld toe or the main plate and then propagated. As a result, the corroded joints had the same or higher fatigue strength than the uncorroded ones when the number of corrosive environmental cycles (S6-cycle) was less than 1800 cycles.
