Abstract

Although seismic events only rarely cause structural damage to buried pipelines, they can nevertheless sometimes result in a significant loss of functionality, which will hamper recovery in the affected areas immediately following the earthquake. While the dynamic response of a pipe is obviously dependent on the characteristics of the seismic event and the type of pipe in question, a careful assessment of the stresses induced by the earthquake cannot neglect the interaction between the pipe and the surrounding soil. In the present paper a numerical model is developed for evaluating the dynamic stresses acting on buried pipes under the hypothesis that the soil is a Winkler elastic m
