Time histories of responses using the vehicle-bridge coupling dynamic system: (a) vertical displacement of the bridge deck under the action of a 2-axle vehicle; (b) contacting force between the tires of a 2-axle vehicle and the bridge deck; (c) vertical displacement of the bridge deck under the action of a 3-axle vehicle; (d) contacting force between the tires of a 3-axle vehicle and the bridge deck; (e) vertical displacement of the bridge deck under the action of a 4-axle vehicle; (f) contacting force between the tires of a 4-axle vehicle and the bridge deck; (g) vertical displacement of the bridge deck under the action of a 5-axle vehicle; (h) contacting force between the tires of a 5-axle vehicle and the bridge deck; (i) vertical displacement of the bridge deck under the action of a 6-axle vehicle; (j) contacting force between the tires of a 6-axle vehicle and the bridge deck.
