Probabilistic dynamic analysis of vehicle-bridge system

The dynamic response of a bridge under a moving vehicle with random system parameters is studied. The vehicle is modeled as a spring-mass system and the bridge is assumed to be a simply supported Euler-Bernoulli beam. The vehicle’s mass and stiffness, and the bridge’s parameters corresponding to Young’s modulus, mass and moment of inertia, are all considered as random variables. The computational expressions for the mean value and standard deviation of the vertical response of the bridge are developed by using the modal superposition method and random variable’s functional moment method. The effects of the vehicle’s and bridge’s parameters on bridge’s response are investigated. (a) For the covering record of this conference, please refer to ITRD abstract no E218284.
