Transverse seismic analysis of buried pipelines

The objective of this study is to develop an analytical procedure for calculating upper bounds for stresses and strains for the case of the transverse seismic shaking of continuous buried pipelines taking into account the soil-pipeline interaction effects. A sensibility analysis of some critical parameters is performed. The influence of various parameters such as the apparent propagation velocity, the frequency content of the seismic ground excitation, the dynamic soil properties, the pipe`s material and size, on the ratio of the pipe to ground displacements amplitudes and consequently to the induced pipe strains, are studied parametrically.
