Summary:ÌýThe objective of this study was to impose externally applied axial loading to reinforced gasketed water pipeline joints to establish upper bound performance under worst case conditions of ground movement.Ìý Test protocols included axial tension and cyclic (progressive tension and compression) loading on bell-spigot style C900 PVC pipe to simulate deformations possible during natural hazards such as earthquakes and landslides . The test specimens consisted of either RieberLok Gasketed or Diamond Lok-21 pipe with a restraining ring. Tests provided measures of axial displacement capacity, pipeline connection strength, and failure mechanism. The results indicated these systems as potentially viable solutions for regions prone to persistent soil movement and settlement. Tests were conducted in partnership with Denver Water.
