Seismic Design of Buried Pipeline Systems

This book discusses the application of seismic design methods for lifeline earthquake engineering to buried pipelines so that readers can analyse their behaviour and structural and functional characteristics, verify the results, and apply appropriate methods to design earthquake-resistant lifelines. The authors focus on four key areas to provide readers with this understanding.First, they comprehensively explain seismic design methods for lifelines by systematically discussing the seismic design methods of expansion and contraction flexible joints.Second, they describe in detail the theoretical background of design formulas for seismic design of pipelines (the “slip concept") and verify the applicability of the design formulas to the elasto-plastic state assumed by the current design method by comparing them with FEM analysis results.Third, they explain how to verify the validity of FEM numerical analysis in line with the theoretical background of the design formulas.Last, they discuss
