Abstract:

In this paper criteria and related features are described pertaining to the seismic design of pipelines and pipeline systems. The presentation begins by describing the past performance of pipelines in earthquakes, and identifying the key ground motion parameters, geotechnical parameters, and structural factors of concern in design of pipeline systems. The seismic effects addressed include vibratory effects, relative ground motion, surface faulting, soil liquefaction, landslides, tectonic uplift and subsidence, and traveling seismic waves, all of which can lead to overstraining. Techniques for estimating these effects and for handling them in design, including connections and penetrations, soft soil bedding, and transition from soft to hard zones, are described, with reference to where more detailed analysis and design treatment can be located.
