Abstract

The problem of dynamic non-linear response of a suspension bridge to the passage of a train of concentrated forces with random weight is considered. Force arrivals at the bridge are assumed to constitute a Poisson process of events. Thus, the excitation process idealizes vehicular traffic loads on a bridge. By use of both iterative and linearization methods the solution for the expected value and variance of the bridge's deflections is determined. As an example, the response of a bridge to a stationary stream of forces is obtained. A numerical technique is developed to compute the solution for a particular bridge and some practical cases of the loading.
