✦ Synopsis

The dynamic response of continuous structures to a stream of arbitrary impulses is considered. The impulses commence at random times and are located at random points on the surface of the structure. The shapes of the impulses can be arbitrary and can have a deterministic or stochastic nature, both i n time and in space. The respective time durations and amplitudes of the impulses are also random. An analytical technique is developed to determine the response of the structure, and explicit expressions are provided for the expected value and covariance of the structure deflection. The results presented in the work can be used, for example, in estimating the reliability of bridge loading by traffic flow.
