Presented herein is a summary of the results from the first two years of a fouryearstudy on damage detection and health monitoring of buried, segmental concretepipes, such as those used in urban water distribution networks. The rapid assessmentof damage to such networks from earthquake-induced permanent grounddeformations is an essential component to recovery efforts. To identify the failuremodes that occur in the pipelines subjected to permanent ground deformation and toassess the performance of sensor technologies for detecting these modes and forpotential use in situ, large-scale tests were performed at the NEES LifelineExperimental and Testing Facility at Cornell University. The predominant failuremodes identified in the tests performed to date include compression at all joints andcombined compression and bending at the pipe joints closest to the fault. Accuratemeasurements of the pipeline displacements and strains were recorded up to thecompressive and flexural failure of the pipeline joints.
