Abstract
Closed form analytical relations are developed for wave propagation effects on buried pipelines which interconnect tanks and/or buildings. The relations cover the axial strain induced in a pipe with various end conditions, the induced axial force at the pipe/tank interface, and the relative displacement at the tank for a pipe with a free end condition. The relations utilize the concept of a pipe development length, defined as the distance over which soil friction forces must act to induce a pipe strain equal to a given level of ground strain. If the available length is less than this development length, the pipe strain is less than the ground strain. Finally an example illustrates the application of the relations and presents simplified upper bound values for pipe strain, axial force, and relative displacement.
