Bridge structure is subjected to fatigue analysis, the vehicle load loading method for medium and small span bridges is relatively mature, while the load analysis method for large load bridge fatigue analysis vehicle load is still rare. This paper summarizes the vehicle load loading method for fatigue analysis of medium and small span bridges in foreign countries. Based on the sling of a large span suspension bridge, a vehicle load loading method for sling fatigue analysis of long span suspension bridges is proposed. The vehicle load loading method is compared and analyzed, and the relevant conclusions of this study are proposed, which provides a reasonable loading method for the fatigue analysis of long-span bridge cable structures.
