Abstract:

To obtain the dynamic response characteristics of long-span continuous beam bridges under coherent excitation of the bridge deck, a comprehensive analysis was conducted based on the principle of virtual work. Firstly, a dynamic model of a five-axle heavy-load vehicle was established. Then, the bridge's dynamic equation was derived using the modal superposition method, a wheel-deck coherent excitation model was established by considering the geometric and mechanical coupling between the wheels and the bridge. The coupled vibration analysis system of the long-span continuous beam bridge was implemented using Matlab software. Subsequently, the impact of different levels of coherent deck excitation models on the dynamic response of the bridge was investigated. The findings revealed that when the influence of bridge deck irregularity was ignored, the impact coefficients of the bridges were smaller than the standard values. However, as the condition of the bridge deck deteriorated, the dynamic response of the representative cross-section of the structure increased significantly. Moreover, it was observed that the completely coherent excitation model had a greater influence on the dynamic response of the bridges compared to the partially coherent excitation model, exceeding the standard values. The maximum deviation of the deflection amplitude was approximately 7.7%, with a maximum deviation of bending moment amplitude of around 20%. The relative errors in deflection impact coefficient ranged from 4% to 34%, while the relative errors in bending moment impact coefficient ranged from 2% to 43%. Additionally, it was noted that the impact coefficient of the bridge initially increased and then decreased with an increase in vehicle speed. Finally, an envelope diagram illustrating the deflection and moment impact coefficients of the long-span continuous beam bridge was provided. These research findings offer valuable insights for the analysis and study of the structural dynamics and response of continuous beam bridges.
