Vehicle load loading method for the fatigue analysis of long-span suspension bridges with straddling slings
In this study, the bridge structure is subjected to fatigue analysis. While the vehicle load application method for medium- and small-span bridges is relatively well-established, methods for fatigue analysis of large-span bridges under vehicle loads are still limited. This paper summarizes the vehic...

| description | In this study, the bridge structure is subjected to fatigue analysis. While the vehicle load application method for medium- and small-span bridges is relatively well-established, methods for fatigue analysis of large-span bridges under vehicle loads are still limited. This paper summarizes the vehicle load application 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 application method for sling fatigue analysis in long-span suspension bridges is proposed. The proposed method is compared and analyzed, and relevant conclusions are drawn, which provides a reasonable approach for the fatigue analysis of cable structures in long-span bridges. |
