What is Analysis of Buried Pipelines Subjected to Reverse Fault Motion about?

## Buried pipeline Finite element analysis Nonlinear quasi-static analysis Structural design of pipelines Oil and gas pipelines Earthquake induced ground movements Pipe-soil interaction Pipeline buckling Reverse fault motion a b s t r a c t Presently available simplified analytical methods and semi-empirical methods for the analysis of buried pipelines subjected to fault motion are suitable only for the strike-slip and the normal-slip type fault motions, and cannot be used for the reverse fault crossing case. A simple finite element model, which uses beam elements for the pipeline and discrete nonlinear springs for the soil, has been proposed to analyse buried pipeline subjected to reverse fault motion. The material nonlinearities associated with pipe-material and soil, and geometric nonlinearity associated with large deformations were incorporated in the analysis. Complex reverse fault motion was simulated using suitable constraints between pipe-nodes and ground ends of the soil spring. Results of the parametric study suggest that the pipeline's capacity to accommodate reverse fault offset can be increased significantly by choosing a near-parallel orientation in plan with respect
