EQE 696 – Special Topics in Earthquake Engineering: “Seismic Safety of Buried Pipelines"

COURSE NO AND TITLE : EQE 696 – Special Topics in Earthquake Engineering: “Seismic Safety of Buried Pipelines

INSTRUCTOR : Assoc. Prof. Dr. Eren Uçkan
 
COURSE OBJECTIVES :  The course focuses on the seismic analysis and design of buried pipelines subjected to permanent ground deformations and wave propagation hazard.  Simplified procedures will be presented  to quantify the response  of buried pipes subject to  different earthquake hazards. 
 
COURSE SYLLABUS : 
  • Introduction and Observed damage
  • Classification of  pipelines: Segmented and continous pipes, on shore (buried)  and off-shore  water and hydrocarbon transmission pipes
  • Earthquake hazard: Wave propagation (WP) and Permanent  Ground Deformations (PGD)
  • Design criteria
  • Pipe Limit States and Failure Criterion
  • Simplified models: Beam on elastic foundation method
  • Response of Buried Continuous Pipelines to Transverse PGD
  • 3D Nonlinear Pipe-Soil interaction model
  • Response of Buried Continuous Pipelines to longitudinal and Transverse PGD
  • Response of Buried Continuous Pipelines to faulting
  • Performance based design
  • Seismic Fragility Relations for Buried Pipe
  •  Countermeasures to Mitigate Seismic  Damage
  • Applications:  Simplified models and  3D FE models

PREREQUISITES : Familiarity with the commonly used FE software
 
DURATION & HOURS PER WEEK : 12 weeks, 3 hours/week   / 3+0+0
 

GRADING BASIS : 

Quiz + Term project + Presentations ; no mid-term or final exam.
