Abstract

In seismically active regions, buried pipelines can be subjected to severe ground deformations due to faulting, landslides, lateral spreading and seismic settlement. The permanent ground deformations (PGD) may induce large strains in the pipeline. Prediction of those pipe strains is required to evaluate pipeline performance and to design earthquake resistant pipelines. Therefore, development of analytical or finite element (FE) model of the problem is necessary. The behavior of buried pipelines crossing faults have been analyzed by several researchers in the past using static analysis due to static nature of fault loading. Consequently, ABAQUS/Standard module is widely used to solve soil-pipeline interaction problems under faulting since it is capable of performing static/quasi-static analysis. In this study, an ABAQUS/Explicit model, which is mostly used for dynamic analysis, was developed to simulate pipelines crossing strike-slip faults considering an energy balance concept. The model results were compared to ABAQUS/Standard and analytical results for validation purpose. The comparison of the results shows that ABAQUS/Explicit module is a reliable tool to effectively analyze quasi-static loading problems.
