Abstract
Overall aims of this research are to develop a systematic way of assessing the adequacy and vulnerability of water/sewer distribution systems subjected to seismic loads and also to develop future design methodologies for water/sewer systems. Because of the geographical extent of buried pipelines, analysis and design procedures for buried pipelines are quite different than the standard procedures developed for building type structures. The purpose of this paper is to investigate the following assumptions which form the basis for the presently available seismic design procedures for buried pipelines subjected to ground shaking. (1) It is assumed that there is no relative motion between the pipe and the soil; and (2) It is assumed that the shape of the seismic waves does not change as it traverses the pipeline.
