The Role of Soil Structure Interaction in the Fragility Assessment of HP/HT Unburied Subsea Pipelines
Subsea high pressure/high temperature (HP/HT) pipelines may be significantly affected by the effects of soil structure interaction (SSI) when subjected to earthquakes.Numerical simulations are herein applied to assess the role of soil deformability on the seismic vulnerability of an unburied pipeline.Overcoming most of the contributions existing in
