Abstract: To obtain bridge accelerations, a dynamic analysis of a bridge is conducted to use a vehicle-bridge interaction model. The load exerted the passing vehicles is a mix of dynamic loading caused by the uneven bridge deck, which creates bridge vibration. Bridge vibration vehicular has a detrimental impact on numerous elements, notably driving safety and pedestrian comfort. As a result, an effective and precise technique to forecasting bridge vibration due to vehicle passing is required at the design stage. A reaction spectrum model is suggested in this paper to predict the bridge root-mean-square (RMS) acceleration response caused by a single-vehicle passage. A Kalman filter-based approach was used to extract the vehicle dynamic loads from a field test. The vibration based NDT, Analysis model in MIDAS, Comparetative study, VBDD methods and Numerical approach is used in these paper.
