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.
