The dynamic interaction problem of a moving vehicle on the sustaining bridge with uncertain system parameters is studied. The vehicle is modeled as a two-degree-of-freedom spring-mass system and the bridge is assumed to be a simply supported Euler-Bernoulli beam. The vehicle parameters and bridge parameters are considered as random variables. Expressions of the mean value and standard deviation for the displacement response of bridge are developed by using the modal superposition method and random variable functional moment method. The effects of vehicle and bridge parameters on the bridge response are investigated. © 2011 Taylor & Francis Group, London.
