Seismic Performance Evaluation of Buried Pipelines Retrofitted with Cured-in-Place Pipe Liner Technology under Near-Fault Ground Motions

Seismic vulnerability of buried pipelines has been identified in many post-earthquake reconnaissance reports. Efficient retrofit of critical lifelines to improve their seismic performance becomes an urgent requirement nowadays. The cured in place pipe (CIPP) liner technology is an effective trenchless method for repairing existing underground lifelines with minimal ground surface disruption. However, the seismic performance of CIPP …
