A Study on the Impact Coefficient of Traffic Flows on a Large Cable-Stayed Bridge in a Windy Environment

Figure 17

Time histories of responses at point C of the bridge under the action of wind loads and traffic flows: (a) vertical displacement; (b) vertical moment; (c) contacting force of a 4-axle vehicle with the bridge deck at the wind velocity of 49.8 m/s; (d) surface roughness and additional roughness at one of the contacting points of a 4-axle vehicle’s tires with the bridge deck.
