Seismic Analysis of Buried Steel Pipelines Subjected to Strike-Slip Fault: FEA Study
Publication: Pipelines 2022
ABSTRACT
The purpose of this study was to evaluate the nonlinear response of the steel buried pipelines subjected to pipe crossing a strike-slip fault. When pipe crosses a strike-slip fault, the fault moves horizontally. A strike-slip fault can cause significant plastic deformation in the buried pipeline. This analysis is based on numerical simulation of the nonlinear response of the soil-pipeline system through finite element analysis using ABAQUS software. The structural response of a buried steel pipeline in different soil conditions subjected to strike-slip fault movement was evaluated. The parameters evaluated were the soil modulus of elasticity and frictional angle of soil-pipeline system. Stresses at different distances from the middle of the pipe were captured for three circumferential locations: crown, springline, and invert. The results of the FEA analysis were compared with the analytical solution. The present study results can be used to develop and improve steel pipe design methodologies for buried steel pipelines in earthquake hot spot areas.
