✦ Synopsis
In the present paper a semi-analytical methodology for a nonlinear stress-strain analysis of buried steel pipelines at active fault crossings is presented and verified. The developed model introduces a number of critical refinements to the existing methodologies which extend the application area of analytical models in pipeline design. In particular, a strike-slip and normal-slip fault crossings can be analyzed taking into account material and large displacement nonlinearities, nonlinear pipe-soil interaction. The proposed model is verified against the results by other authors and numerical results, obtained with the finite element method.
