This study centers on experimental assessments of AWWA C900 DR14 iPVC pipes, subjecting them to bending forces. The primary objective was to determine the pipes’ capacity to maintain their full-service functionality following seismic events, thus bolstering seismic resilience. To explore this, two types of restraints were employed to connect the pipes, and rigorous lab tests were executed. These tests entailed applying a monotonic force at the center of the specimens, oriented perpendicular to the pipeline’s direction. The experiments continued until reaching critical points, such as severe pipe damage or significant water leakage. For a comprehensive understanding of the deformation and failure mechanisms involved, distributed fiber optic sensors were deployed. This study also delves into the distinct failure modes related to the use of different restraint systems.
