Abstract In this paper, the main empirical formulas of collision force between ships and bridges are introduced respectively, which are adopted to calculate collision force for four Yangtze River standard bulk carriers. The non-linear finite element analyses are used to calculate the collision force with different DWT and velocities of ships as well. The curves between collision forces and DWT or velocities could be referenced in the bridge piers design. Comparing the collision force between ships and bridges with FEM and formulas, the formulas of JTG and TB are more suitable than IABSE and IABSE to calculate the collision force between bridge and V bow bulk carriers whose DWT are between 500t and 3000t.
