In order to explore the effects of ground shaking on buried lifelines new experiments were devised. Single gravity model shaking table experiments were developed and conducted to examine the response of instrumented pipes buried in dry sand when subjected to shaking. This study was aimed to obtain a better understanding of the behavior of embedded lifelines by considering the effects of geometrical complications. Since, such structures may be close to underground concrete walls of adjacent buildings in an urban environment, the influence of nearby concrete structure was also investigated. Details of the experimental setup and procedures are first explained. Then, test data are discussed in terms of longitudinal bending moment and soil pressure distribution of model structures as well as P-Y curves.
