Based on the summary of the existing analytical methods of buried steel pipelines at crossings with active strike-slip faults, an improved analytical methodology herein is proposed. Based on Karamitros model, the Ramberg-Osgood stress-strain relationships of pipe steel and the effects of nonlinear soil-pipeline interaction in both the axial and transverse directions are taken into account. Compared with existing analytical methodologies and 3D nonlinear finite element analysis, the analytical methodology presented is suitable for engineering applications due to exact and conservative results.
