Seismic Pipeline Design with Ductile Iron Pipe – Allen Cox, PE

This presentation reviews the general design approach for underground ductile iron pipe applications in areas where seismic events such as lateral earth spreading, liquefaction, and fault rupture, etc., result in permanent ground deformation as well as unstable slopes and sinkhole areas. A brief discussion of past experiences is presented along with the various design mechanisms that are to be considered. These factors include the available joints, the deflection and expansion/contraction capacity of those joints, and the strength of the pipe material. The talk also provides a model for engineers and utilities to use to ensure good design for pipelines at risk in seismically active areas. Register here
