Abstract: There are a large number of welded fatigue weak points in steel deck which are prone to fatigue damage under cyclic loads.The second structural system effect has been mainly considered in domestic and international study of the mechanical properties and details fatigue of steel deck.The first structural system effect of fatigue stresses by replacing the corresponding position of fish bone beams with whole shell element through hybrid finite element method,and choosing the fatigue curve of Eurocode to calculate the cumulative damage of fatigue details.The results show that compression beam segment is no need for fatigue checking,while the effect of whole structural system can be ignored in fatigue assessment of tesion beam segment of steel deck.
