Abstract：The fatigue property of the bridge crane girder under random fatigue load is researched in the paper , and the static characteristics in five typical structural conditions were analyzed by finite element software .The results showed it is easy to be stress concentration and cause fatigue cracks , in fillet weld seat between web plate near the 1/2 cross and low cover plate , and the connection welded toes between transverse stiffened thin plate and web plate .Stress key node ’ s stress curve and its corresponding load spectrum of the crane main gird-er are determined by multi load step transient analysis .The FE-safe software is used to calculate the fatigue life under various load time based on the results of finite element analysis .Finally, according to statistics , the fa-tigue life of crane girder is estimated .
