Seismic Design of Buried Pipeline: Past, Present and Future

Sasan M. Iranpour, Ph.D., P.Eng.

A review of seismic design criteria of buried pipelines shows that these

criteria are not yet fully established. This study reviews the past

methods and recent developments for the seismic design of buried

pipelines, and highlights areas that require more research to develop a

systematic design procedure for practicing engineers.

Using an approach recently implemented by the author, it shows how a

coupled fully nonlinear soil‐structure interaction analysis can be

implemented to design a ductile pipeline system, hence reducing the

possibility of brittle fracture. This, in turn, makes it possible to complete

a design for projects where the available code‐based engineering

approaches cannot provide a solution, and a more robust analysis and

design approach is required.
