| Abstract: | The vertical loaded free frequency of 3×64m continuous steel truss bridge is influenced by the under-spring mass and the stiffness of the spring for each wheel-set of the vehicle, the vehicle’s length and the mass of the vehicle. But it is independent of the velocity of the train. The conclusion accords with the simply supported bridge. |
