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 behaviour of such structures by considering the effects of geometrical complications. Since, such structures may be close to underground concrete walls of adjacent

Then, test data are discussed in terms of longitudinal bending moment and soil pressure distribution of model structures.
