Original design incorporation or retrofitting for seismic resilience can play a major role in mitigating the potential damage of buried pipelines from seismic events or merely unstable soils.  Seismic hazards include ground displacement, ground deformation, ground subsidence, or even liquefaction.  Each of these hazards could devastate pipelines not adequately designed to tolerate them.  This presentation discusses: 

  • Seismic Design Standards and the protective framework they provide, 
  • Contributive pipe material properties such as tensile strength, restrained joint deflection along with expansion / contraction capabilities, and  
  • recent developments in earthquake resistant DI pipe couplings (ERDIP).
